猫湿疹用什么药

1、湿疹简介猫湿疹是一种基于过敏反应的皮肤病,主要表现在耳后、面部和脖子等位置,患处皮肤会出现红肿、瘙痒和炎症等症状。令人遗憾的是,这是一种难以治愈的病症。所以,在治疗的过程中,需要不断尝试以找到最有效的医治方案。2、常用的湿疹药物许多的药品可用来治疗湿疹,但很少有一种药即对所有患者都有效。以下是一些常用的药物:2.1类固醇药膏类固醇药膏是针对炎症及瘙痒等症状的治疗药物。由于使用不能过度,以及会导致副作用,如皮肤变薄,所以请仅在症状加剧时使用。2.2抗生素使用抗生素是针对由细菌感染引起的症状的选择性治疗药物。抗生素可口服或者外用,但也许会引起副作用。所以在使用前,请咨询兽医或者有资质的药剂师。2.3TopicalImmunomodulators局部免疫调节药物是一种新型药物,用于防止炎症和其他湿疹症状。虽然对猫的作用有限,但这类药物对于患者是绝佳的选择。如果在治疗过程中感到不适,应立即停药并咨询兽医。3、选用药品时的注意事项保证病情能够得到有效治疗的同时,还需要在选择药品时注意以下几点:3.1药品的副作用药物的使用还许会产生意想不到的过敏反应,如呕吐、腹泻、中毒等。在使用药物时,请咨询兽医,并在使用过程中密切观察猫咪的反应。3.2药物的用法与用量严格按照指示使用药物,并且不要自行调整药品用量。如果使用不当,则会导致对猫咪的进一步威胁。如果对药品使用方法不确定,建议咨询兽医。3.3治疗时的环境在猫咪湿疹治疗过程中,请保持它的环境整洁和清爽,避免使用有刺激的化学药品。总的来说,治疗猫湿疹是一个需要耐心和坚持不懈的过程。虽然湿疹并不容易治愈,但在经过兽医的指导并积极的行动中,您的猫咪还是可以得到有效的治疗。

请求详细解析一道英语阅读题

CABD 68、 If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements这句话中的they could be expected to show surprise in their faces and movements表示说。如果小孩show surprise 的话,就说明他们可以认知道原本在的东西不见了,这是对事物的一种认识。而不是A所说的视觉效果,因为他们都是可以看到的。B是实验堆baby的影响也不对,D是不同的实验来测试baby的感觉,也不对69 、We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land? 这短话是说把box藏在门背后,然后当box消失的时候看baby是否会惊讶,显然16周和22周的baby给出了不同的反应。所以答案显然是A。70、文章第三段以后很多次提到了screen,所以实验者显然用到了screen来作为道具,所以选B71、可以用排除法来做:A,实验中给孩子们看到东西在哪里,并且孩子可以找到。所以错B,train 和ball 是实验者的道具,并不是baby的选择。所以错C,这是实验者的实验,不是baby自主想要做的事情。所以错答案只有D是正确的,孩子无法辨别真实的东西跟视觉虚拟的东西。

英语过去式作文,My busy day.

My Busy Day>Here begins the tale of my day of many mods. I am going to withhold the names and location of where I got my work done, since the Midwest is conservative, and the city where I got my work done has outlawed scarification, and I don"t want to get anyone who helped me to get into any trouble for a good deed they did.I don"t claim to be any less crazy than any of you who submit to this site (not that I"m passing judgment), and my times of turmoil have had their effect on me. At one of my craziest times, about a year ago, I went through a cutting phase and did about 50 cuts with razor blades, obviously not the smartest thing to do. From that exposition, the most prominent scars were two large ones on my upper arms. They are approximately eight inches long and between 1/4" to 1/2" thick. I wanted to take control of them and turn them into something beautiful, and not let them have control over me. I don"t want them to be a reminder of how crazy I can be; I want them to be a reminder, a beacon of how I am in control of my body, my actions, and my life.I worked at a piercing/tattoo parlor and I was moving, so I needed to have all of my work done before I left. I was adding to the scars on my arms, branding around the scar on my right arm, and scalpeling around the scar on my left arm, getting my guiche pierced, and finishing a large tattoo on my right thigh. The day of my mods, I was very excited, nervous, and a bit scared. I made sure to eat plenty of food for lunch; I knew I was in for a long day. My one concern was that, since I was moving, I had gone out with a friend the night before, and was a bit hung over. But I was going to stop because of that. I got to the shop a little after 4. I was having two different piercers do the cutting and burning, so as I entered the piercing room, they followed me in. After we got done talking about my impending move and work about to be done, they began to mark the spots on my arms, draw up sketches for reference, and see how my skin moves so that the scars would heal evenly, and not bulge out in spots. We also put some topical anesthetic on my right arm, because, hey, I had never been burned before, and I wasn"t sure how bad it was going to hurt.I was getting the cutting done first, and after the lines were marked, we locked the door and got to work. I was getting six lines cut in all, and I was anxious to get to it. The first line was good, I have some masochistic tendencies, and I"ve always been a fan of how cuts feel. "The old familiar sting," to quote NIN, felt superb. We used four scalpels all together, I think and each cut felt better and better. I could feel my skin open up, and it was wonderful. There was a lot of blood, and we got some good pictures of me with my piercer. We did a pressing of the cuts, so I have the shape of them in a blood outline that I still have yet to frame. They now look really good, I just need to get the bottom cut gone over again a little deeper, because we went over it tentatively because it was the first cut. I am really pleased with how it turned out.After that I went out and had a cigarette, I needed to relax a little. I wasn"t in pain, I was just too excited and my adrenaline and endorphins had me bouncing off the walls. I went back in and it was time to get my guiche done. I wasn"t at all worried about getting that done, I had it done before, so I knew what to expect. It wasn"t healing well the first time I had it done, so I took it out, and I had the jewelry sterilized so I could try it again, hopefully with better luck this time. The jewelry is a sweet 6-gauge 5/8" diameter pink titanium circular barbell. I took off my pants, lied on the table, spread my legs and had the piercing done. Something that has consistently surprised me has been how little genital piercings hurt, well, at least all of them other than my apadravya. To report on how my guiche is doing: sadly enough, it fell out last week. I went to take a piss, and lo and behold, the fucker was gone. I guess I"m just not supposed to have a guiche piercing. < p> After another cigarette and a can of Coke, I was back in the room. I felt stoked cause I was halfway done with my list of stuff for the day. The anesthetic had started to work, which was good, because it was time for the branding. I was doing six curved lines around this scar, and we had only one cautery pen, so I hoped things proceeded well. The piercer who had done my cutting warned me that the pen might not hold up for the entire length of what we needed. This branding would be done by the pierced who had just done my guiche. I lied back on the table, and it was time to begin. The anesthetic helped a bit, but there were some parts where I could definitely feel the searing of my skin. It was pretty intense, but once I focused my thoughts, the tingle felt almost good. The stench, however, was horrible. We had the windows open and some incense burning, but damn. The smell of burning flesh was permeating everywhere. And all of a sudden, mid-line, then pen burned out. The othe r piercer was like "told you so." So, the piercer told me to come back in about three months to get it finished. We left the room and then stunk up the whole studio. The place smelled like a crematorium. The smell of singed flesh and hair was thick in the air, and since it was a Friday night, it was busy in the shop, and many of the patrons had a disgusted look on their faces. It scabbed really well, much to the delight of my girlfriend. Apparently she"s a huge fan of scabs, and was begging me every day to let her pick them off. All the scabs are off now, and they look really good. Just another two months and I can get it finished.After yet another cig break and some food and pop to keep my blood sugar up, it was time to get tattooed. I had about two hours ahead of me. I don"t remember exactly how much time it took, by that point I was fairly worn down. I sat for that, and it turned out really well. It"s a large Ganesh piece on my right thigh. I love that tattoo so much.So after my long day, I was fuckin" beat. I had been cut, pierced, branded, and tattooed. I felt tired and weary. Another unfortunate thing was that since I was moving, I had a going away party to go to that night. I was so tired and weary. And then I didn"t even get to leave the party and get to bed until after 7am. Then I woke up at 3pm the next day and dropped acid with a friend of mine. So it was a great way to finish my stay in the city. And my body was, amazingly enough, able to withstand it all.

什么是有机食物

摘要:有机食物是以生命养生命的一种绿色循环,那么,有机食物与无机食物的区别是什么呢?有机食物完全不含有没有生命存在的化学成份。它是以微生物培植或自然转换成的天然的养份来孕育各种人们可食用的植物。对人类健康不存在任何的威胁。下面小编就详细为您讲解什么是有机食物,有机食物与无机食物的区别。【有机食品】什么是有机食物有机食物与无机食物的区别什么是有机食物有机食物是零污染的食物,即是不经过化肥、农药、除草剂等污染的食物,而且肥料必须用自然堆肥,凡是任何加害土壤的添加物,都不可使用。一、有机食物简介有机食物简单的讲,就是以生命养生命的一种绿色循环。它完全不含有没有生命存在的化学成份。它是以微生物培植或自然转换成的天然的养份来孕育各种人们可食用的植物。对人类健康不存在任何的威胁。这包括;蔬菜、水果、禽蛋、各种肉类等等,不胜枚举。总之,它是天然的、无害的、对人身体有益的健康食品。有机食物是极低污染的食物,即是不经过化肥、农药、除草剂等污染的食物,而且肥料必须用自然堆肥,凡是任何加害土壤的添加物,都不可使用。目前经认证的有机食物主要包括一般的有机农作物产品(例如粮食(包括有机大米、有机小米、有机五彩豆、有机荞麦、有机绿豆、有机黄豆、有机红小豆、有机黑豆、有机玉米糁等)、水果(包括有机草莓、有机苹果等)、蔬菜(包括有机生菜、有机西红柿、有机黄瓜等)等)、有机茶产品、有机食用菌产品、有机畜禽产品、有机水产品、有机蜂产品、采集的野生产品以及用上述产品为原料的加工产品。国内市场销售的有机食品主要是蔬菜、大米、茶叶、蜂蜜等。二、有机食物标准食品1.农作种植的水源、土壤与原料、肥料必须符合有机农业标准。2.生产、收成及加工过程不得使用杀虫剂、合成(化学)肥料、农药、化学添加物。3.土壤必须休耕三年。4.食材不得经过任何基因工程改造。5.必须通过政府机构的管制与认证。有机食物农场1.使用天然肥料(堆肥)来喂养土壤,增加土壤养分。2.耕种前经过三年的休耕,让土壤里残馀的有毒物质自然消失。3.耕种过程不使用农药、杀虫剂、合成(化学)肥料。4.尊重天然的生态系统及循环。有机食物饲养1.饲料必须符合有机规范的天然饲料。2.一定要在适合其生存的自然户外环境放养。3.禁止使用抗生素、荷尔蒙或生长激素。4.人道对待饲养的动物。三、有机食物特点1、使用有机肥料:有机食物的种植过程中,只会使用有机肥料,如:花生麸、角衣片和动物的骨粉等,这些天然材料对泥土构成的污染和负荷会减到最低,环保得很。2、使用有机农药:除了种植方法是有机外,防虫的过程也会用有机农药,非常天然,以达到生态平衡、维持生物多样性,令食物不会含有有毒或长期残留的化学添加剂、色素和化学防腐剂等,无论对健康和对环境都有莫大的好处。3、取得有机认证:不同国家都为“有机耕种”定义,在美国,所有使用organic这字的产品,都受美国农业部国家有机标准计划(usdanationalorganicprogram,nop)规管。而世界各地也有不同的官方或私营认证机构。它们会按本身所制定的标准提供认证服务,英国土壤协会(soilassociation)和欧洲的ecocert就是当中的例子,而在众多的认证中,取得ocia和美国usda认证较有保证。四、有机食物争议英国一个研究小组在考查了50年来发表的有关有机食品的文献后得出结论:有机食物并不比用传统方式生产的食品营养价值更高。不过,这项研究没有涉及到与不同农业生产方法相关的污染物或化学残留物。有机食品的一个主要卖点就是无化学添加剂。总部位于新泽西州的行业协会食品研究所(FoodInstitute)所长托德(BrianTodd)回应这项研究时说,有机食品中没有非有机化学物质和杀虫剂,这才是有机食品的诱人之处。这项研究是由伦敦卫生及热带医学学院(LondonSchoolofHygiene&TopicalMedicine)的研究人员进行的,报告发表在周三出版的《美国临床营养学杂志》(AmericanJournalofClinicalNutrition)上。研究报告的作者之一、该学院公共卫生干预研究部门的丹格尔(AlanDangour)说,研究发现有机食品和传统方法生产的食品在营养成分上存在一些差异,不过这对公共健康不太可能有任何影响。由于有机食品据说有健康和营养方面的益处,一些消费者愿意花更多的钱买有机食品。研究人员们说,2007年全球有机食品市场估计规模有290亿欧元(合411亿美元)。其他研究也曾得出结论说有机食品并没有更高的营养,不过研究报告的作者们说,他们的努力是对有关这一课题的已发表报告的第一个系统性评估。在研究中,研究人员搜集了5万多份报告,得出162篇关于有机食品和传统方式生产的农畜产品在营养价值上的对比文章。其中有55篇满足了有机认证和生产食品的种类标准。五、有机食物判断标准1、原料来自于有机农业生产体系或野生天然产品。2、有机食品在生产和加工过程中必须严格遵循有机食品生产、采集、加工、包装、贮藏、运输标准,禁止使用化学合成的农药、化肥、激素、抗生素、食品添加剂等,禁止使用基因工程技术及该技术的产物及其衍生物。3、有机食品生产和加工过程中必须建立严格的质量管理体系、生产过程控制体系和追踪体系,因此一般需要有转换期;这个转换过程一般需要2-3年时间,才能够被批准为有机食品。4、有机食品必须通过合法的有机食品认证机构的认证。六、有机食物与无机食物的区别有机食品是一种原生态的食品,在种植过程中不使用化肥等,从土壤到货品上架都必须严格按照有机食品认证要求。有机产品:被定义为一种利于增进生物多样性、生物循环系统和土壤生物活性的生态生产管理系统,旨在维护、增强生态和谐性。美国相关法规规定有机食品的生长不能使用合成农药、生长激素、抗生素、转基因技术、化肥或下水道污泥。为保证土壤肥力多采用作物轮种、交替耕作与栽培、种植覆盖作物、使用天然肥料等方法。种植有机作物的土地在作物收获前的3年内不能使用任何被禁止的物质,动物需要通过喂食80%的有机饲料9个月,100%有机饲料3个月之后才能称为有机。无机食品:现在没有无机食品这一说法,目前中国市场上只有普通食品没有经过任何认证的,还有一种是无公害食品,还有绿色食品,再就是有机食品,这4种认证的要求是越来越严格,对化肥和食品的添加剂的使用规定也越来越严格,严格意义上讲有机食品是不能含有食品添加剂的。

龋齿【概述】龋齿(dental caries)是牙齿硬组织逐渐被破坏的一种疾病。发病开始在牙冠,如不及时治疗,病变继续发展,形成龋洞,终至牙冠完全破坏消失。未经治疗的龋洞是不会自行愈合的,其发展的最终结果是牙齿丧失。龋齿是细菌性疾病,因此它可以继发牙髓炎和根尖周炎,甚至能引起牙槽骨和颌骨炎症。龋齿的继发感染可以形成病灶(focal infection),致成或加得关节炎、心骨膜炎、慢性肾为和多种眼病等全身其他疾病。【治疗措施】治疗龋齿的主要方法是充填。即将龋坏组织去除净,作成一定的洞形,清洗、消毒以后,用充填材料(filling materrial)填初,并恢复牙齿缺损的外形,龄坏即可不继续发展。浅龋充填效果最好。中龋和深龋的治疗,在去净龋坏组织以后,有时洞底已接近牙髓,就需要在洞底加一层护髓剂再填初。有时深龋在去净龋坏组织以后牙髓就暴露了,就需要先采取牙髓治疗,然后才能填初。充填材料主要用银汞合金(amalgam)或复合充填树脂(composite resin)。乳牙因要换牙,可以用玻璃离子水门汀(glass sonomer cement)填补(暂时性充填材料)。没有形成龋洞的衩期龋,可以用药物治疗的方法,能达到一定的疗效。恒虐待常用氟化钠糊剂涂擦龋损;乳牙可用氟化双胺银(涂擦后有变色,故不用于恒牙)。涂药治疗后,仍可能复发,需要每半年复查一次。因此,治疗龋齿,愈早愈好。【病因学】龋齿是多因素疾病,主要包括三个方面:细菌、饮食、牙和唾液,三者相互关联,缺少一个方面都不能发生龋齿。当前学者们认为唾液作为牙齿的外环境,是重要影响龋病的因素。1.细菌 龋齿发生和发展过程中,由于细菌在龋病发病中起着主导作用,因此,近年来国际上公认龋病是细菌病致龋的细菌种类很多,最主要的是某些变形链球菌和乳酸杆菌。这些细菌与唾液中的粘蛋白和食物残屑混合在一起,牢固地粘附在牙齿表面和窝沟中。这种粘合物叫作牙菌斑或菌斑(dental plaque)。菌斑中的大量细菌产酸,造成菌斑下面的釉质表面脱钙、溶解。临床调查证明口腔中菌斑多的儿童龋齿也多。2.饮食 在龋齿形成过程中,饮食是细菌的重要作用物。食物中含有大量的碳水化合物和糖,这些物质既供给菌斑中细菌生活和活动能量,又通过细菌代谢作用使糖酵解产生有机酸,酸长期滞留在牙齿表面和窝沟中,使釉质脱矿破坏,继之某些细菌又使蛋白质溶解形成龋洞。致龋的糖类很多,最主要的是蔗糖。牙齿发育时期,营养决定牙齿组织的生化结构,钙化良好的牙齿抗龋性高。如果食物中含有的矿物盐类、主要维生素和微量元素,如钙、磷、维生素B1、D和氟等不足,牙齿的抗龋性就低,造成龋齿发病的条件。乳牙在胎儿期即已发生、发育和钙化,母新乳期的营养,对胎儿乳牙的发育虽然没有决定性影响,但加强母体营养仍对乳牙钙化有利的。除非母体患严重代谢障碍病或遗传病,一般乳牙不易受到严重影响。3.牙齿 牙齿的形态、结构和位置与龋齿发病有明显的关系。牙齿咬面的窝沟是发育过程中留下的缺陷,深窝沟内容易滞留细胞和食物残屑,而且不易清除掉,容易诱发龋齿。矿化不足,特别是钙化不足的牙齿,釉质和牙本质的致密度不高,抗龋性低,容易患龋齿。氟在牙齿矿化结构中的含量虽然很微少,但对增强牙齿的抗龋性很重要。牙齿中含适量氟就不易发生龋齿。乳牙和年轻恒牙的结构和钙化程度都还不够成熟,因此容易受致龋因素的影响,患龋率高。唾液是牙齿的外环境,起着缓冲、洗涤、抗蓖或抑菌等作用。量多而稀的唾液可以洗涤牙齿表面,减少细菌和食物残屑堆积。量少而稠的唾液易于滞留,助长菌斑形成和粘附在牙齿表面上。唾液的性质和成分影响其缓冲能力,也影响细菌的生活条件。【流行病学】龋齿是小儿常见的多发病,乳牙患龋率高峰约在5岁左右,恒牙患龋率约在15岁左右。根据上海市1981年调查材料,在15059名幼儿圆儿童和中小学学生中乳牙患龋人数为8523人,乳牙患龋率为56.62%。4岁时患龋率达65.92%,9岁为83.57%。据1983年北京地区对中小学生的调查,城郊区7岁儿童恒牙患龋率平均为48.88%,12岁为67.29%,17岁为73.61%。一般农村较城市人口恒牙患龋为低。资料表明城市人口恒牙患龋率平均为63.65%,平均龋牙数为1.67颗;农业人口患龋率为55.67%,平均龋牙数1.27颗。我国幅员辽阔,各地条件有别,患龋情况也有差别。因此,防龋工作应从牙齿一萌出就开始。【临床表现】龋齿最容易发生在磨牙和双尖牙的咬面小窝、裂沟中,以及相邻牙齿的接触面。前者称为窝沟龋,后者称为邻面龋。儿童发生在牙颈部的龋齿极少,只在严重营养不良或某些全身性疾病使体质极度虚弱时才可见到。根据龋齿破坏的程度,临床可分为浅龋、中龋和深龋(图1)。图1 龋虫及其并发病1.浅龋 龋蚀破坏只在釉质内,初期表现为釉质出现褐色或黑褐色斑点或斑块,表面粗糙。继而形成表面破坏。邻面龋开始发生在接触面下方,窝沟龋则多开始在沟内,早期都不容易看到。只有发生在窝沟口时才可以看到,但儿童牙齿窝沟口处又容易有食物的色素沉着,医师检查不仔细也会误诊或漏诊。浅龋没有自觉症状。2.中龋 龋蚀已达到牙本质,形成牙本质浅层龋洞。病儿对冷水、冷气或甜、酸食物会感到牙齿酸痛,但刺激去掉以后,症状立即消失。这是在为牙本质对刺激感觉过敏的缘故。中龋及时得到治疗效果良好。3.深龋 龋蚀已达到牙本质深层,接近牙髓,或已影响牙髓。患儿对冷、热、酸、甜都有痛感,特别对热敏感,一败涂地去掉以后,疼痛仍持续一定时间才逐渐消失。这时多数需要作牙髓治疗以保存牙齿。深龋未经治疗,则牙髓继发感染或牙髓坏死。细菌可以通过牙根达到根尖孔外,引起根尖周围炎症。可能形成病灶感染。牙冠若已大部破坏或只留残根时,应将其拔除。【预防】预防龋齿是一件非常重要的儿童保健工作,其基本原则是针对发病因素,采用相应措施。1.减少或消除病原刺激物 减少或消除菌斑,改变口腔环境,创造清洁条件是防龋的重要环节,最实际有效的办法是刷牙和漱口。应该加强宣传教育,使儿童从小养成口腔卫生习惯,学会合理刷牙方法。刷牙可以清除口腔中的大部细菌,减少菌斑形成。小儿可由家长用柔软毛巾或绒布擦洗牙齿。幼儿3岁以后就可以开始学习刷牙。尽可能做到早晚各刷一次,饭后漱口。唾前刷牙更重要,因为夜间间隔时间长,细菌容易大量繁殖。要顺刷,即“上虐待由上往下刷,下牙由下往上刷”,“里里外外都刷到”,还要注意刷后牙的咬面。这样就可把牙缝和各个牙面上的食物残渣刷洗干净,刷牙后要漱口。不要横刷,横刷容易损伤牙龈,也刷不净牙缝里的残渣。1975年卫生部、轻工业部和商业部曾共同召开全国牙刷会议,制订了“保健牙刷暂行规格”。1989年卫生部又召开了全国卫生标准技术委员会,由牙刷分会委员会对“暂行规格”。幼儿的牙刷标准毛束不超过两排,每排5~6束,毛质要软,小学生使用的牙刷毛不不超过三排,每排6~7束。又制定了中学生牙刷标准,以备成人牙刷作为参考。应该注意儿童的饮食习惯,按时增加各种辅食,多吃粗糙、硬质和含纤维质的食物,对牙面有磨擦洁净的作用,减少食物残屑堆积。硬质食物需要充分咀嚼,既增强牙周组织,又能磨擦牙齿咬面,可能使窝沟变浅,有利减少窝沟龋。2.减少或控制饮食中的糖 我国是以谷类为主食的国家,控制饮食中的碳水化物防龋是有困难的。但近年来,糖制食品和各种饮料显著增多。应注意宣传使家长教育儿童养成少吃零食和糖果糕点的习惯,睡前不吃糖,注意儿童三餐的质得。从幼儿就养成多吃蔬菜、水果和含钙、磷、维生素等多的食物。要尽可能吃些粗粮。要重视母乳喂养婴儿。近来国际上提倡控制饮食中的碳水化物、使用代糖(sugar substitute)来降低龋齿,这在我国当前是不实际的,也是不经济的。最近据报导美国常用的某种代糖(aspartame)含有毒性,已经引起国际上的注意。3.增强牙齿的抗龋性 主要是通过氟化法(fluoridation)增加牙齿中的氟素,特别是改变釉质表面或表面的结构,增强其抗龋性。近代被认为效果较好的方法有:自来水氟化(central water fluoridation)、学校饮水氟化(school water fluoridation)、牙面涂氟(topical fluoridization)、含氟牙膏刷牙(fluoridetoothbrushing)、氟溶液漱口(fluorde mouthrinse)等方法。自来水氟化防龋是由供水中心自动加氟化钠,使水的含氟量调节到防龋的适宜浓度。这是当前效果最好的方法。对自来水氟化法在国际和国内都有相反的两种见解,因此,只有少数国家和地区采用。我国广州曾试行实验区自来水氟化观察多年,由于加氟量计算不当(采用了世界卫生组织推荐的参考量),导致广州地区儿童发生氟斑牙,引起了家长的不满,现已停止全面加氟。我国地处三个地带,高氟地区很多,各地区水源、气候、农作物等含氟量均有差别,饮食种类和习惯也不尽同,因此,儿童每日摄氟量均需周密计算准确,因此,在我国强调自来水加氟防龋是不现实的。总之,氟防龋方法在高氟区均不能使用,有氟斑牙的儿童也不应使用。钦水氟化法是在托儿所、幼儿园、小学和中学的公共饮水中加入氟化钠,提高水的含氟量的防龋适宜浓度,由于这些儿童在园或在校时间的饮水量小,但加氟量要计算准确。上述两种方法对发育期尚未萌出牙和已萌出的牙都有作用。氟溶液漱口法适用于幼儿园和中、小学校。在有医务人员或老师监督下,推荐使用0.2%中性氟化钠水溶液漱口,每周或每2周1次,含漱1分钟,不得吞咽。是较为可行的方法。含氟牙膏刷牙法,一般浓度不超过0.4%氟化钠,儿童每天早、晚各刷牙1次,有一定降低龋齿的效果,较易推广,也是目前国际上公认的最佳辅助方法。任何氟化防龋方法,都只能用于水源无氟或低氟区。高氟区不能使用。总之,龋齿发病因素是复杂的,当前还没有一种能够预防新龋发生的最有效的单一方法。因此,预防龋齿要防治结合,既控制新龋发生,又要早发现、早治疗。有领导、有组织地开展口腔保健工作,定期在托儿所、幼儿园、小学和初中进行积极预防和早期治疗。同时加强妇幼保健和营养卫生工作,保证身体和牙齿的健康,可以降低龋齿的发病率。

How the relations between language and culture?写200字英文小文章?

The relationship between language and culture It is difficult to say whether language affect the culture or the opposite.But the point we couldn"t deny is that when we mention the language,it"s inevitably to think about its culture.They are bounded to each other.Language and culture are existed at the same time.If there"s no language,then culture is nothing.It"s the premise of the cultural formation and development,and the cultural development has also enriched the language.Language is an important symbol that distinguished human beings from animals.It"s said that there are many mons between them in terms of the biology.But people have the language that animals don"t have.Then religions,belief,morality,custom that belong to culture have been exited.Humans have created culture by taking advantage of language,and in turn,culture has promoted humans toward greater progress.The cultural heritage of human society has embedded the language with a deep mark since ancient times.The human language exists in human culture,it has close relations with human society.Language is an access to understand another culture.It"s a window through which you can find another world.If you want to learn a foreign culture,you have to experience by yourself and by your heart.And the only mean is language.Only after master a foreign language can you bee a part of that society,otherwise the feelings you"ve got are that of others.This kind of feeling will change a bit every through a tran *** ission.It"s not enough to master a foreign language.You also have to know the culture well otherwise we don"t know what others are talking about.Like sometimes watching American movies,I don"t know what the performers are laughing at.Like reading an essay,I can"t realize what the author is trying to express even though I know every world.“He is the person that waves feather fan.” If a Chinese learner wants to know what it means,he has to study the Chinese cultural backgrounds.So foreign language learners have to explore the culture,like how to greet each other,how to introduce guests,how to give and receive gifts,just to name a few.The native speakers learn the cultural knowledge unconsciously.These differences are not the maters of grammar or vocabulary,but the language use rules.It is difficult for language learners to master because of the lack of cultural environment.It"s a general topical.Here I just have talked a few points about the relationship between language and culture.In summary,language is a part of culture,but the most special part which can represent some elements of culture.And in turn,culture has strongly influenced and shaped the language.,4,

加湿器原理 加湿器不出雾怎么办

  加湿器是一种增加房间湿度的家用电器。目前加湿器按用途主要分为家用加湿器和工业用加湿器两种类型。在我们使用加湿器的时候我们应该先了解一下加湿器原理是怎样的,加湿器不出雾怎么办?  一、加湿器原理  目前市场上的家用加湿器一般采用超声波方式将水雾化,并通过风机将雾化的水汽吹出壳体,从而达到加湿空气的效果,其电气原理图如附图所示。市电经过开关电源后,输出两路电压36V和12V。其中36V供电水汽雾化模块.12V供电风机。电路中,D1、D2分别是缺水指示灯和工作指示灯;干簧管为液位检测开关;RT1为雾气大小调节电位器。以02为核心及其外围电路为超声波发生电路。  超声波加湿器采用超声波高频震荡1.7MHZ频率,将水雾化为1-5微米的超微粒子,通过风动装置,将水雾扩散到空气中,使空气湿润并伴生丰富的负氧离子,能清新空气,增进健康,营造舒适的环境。  据专家介绍,超声波加湿器的优点是,加湿强度大,加湿均匀,加湿效率高;节能、省电,耗电仅为电热加湿器的1/10至1/15;使用寿命长,湿度自动平衡,无水自动保护;兼具医疗雾化、冷敷浴面、清洗首饰等功能。  直接蒸发型加湿器也通常被称为纯净型加湿器。纯净加湿技术则是加湿领域刚刚采用的新技术,纯净加湿器通过分子筛蒸发技术,除去水中的钙镁离子,彻底解决“白粉”问题。  热蒸发型加湿器也叫电热式加湿器。其工作原理是将水在加热体中加热到100度,产生蒸气,用风机将蒸气送出。所以电加热式加湿器是技术最简单的加湿方式,缺点是能耗较大,不能干烧,安全系数较低、加热器上容易结垢。市场前景不容乐观。电热式加湿器一般和中央空调配套使用,一般不单独使用。  以上三者相比较,电加热加湿器在使用中没有“白粉”现象,噪声低,但耗电大,加湿器上容易结垢;纯净型加湿器无“白粉”现象也不结垢,功率小,具有空气循环系统,能够过滤空气且杀灭细菌。  超声波加湿器加湿强度大且均匀,耗电量小,使用寿命长,兼具医疗雾化、冷敷浴面、清洗首饰等功能。所以,超声波加湿器和纯净型加湿器还是建议的首选产品。  空气加湿器原理  空气加湿器是把交流电经过变压器降压整流变成直流电,再经过震荡电路把直流电变成高频交流电加到超声波雾化头上(即陶瓷振荡器),陶瓷振荡器有个特点,给它施加外力使其变形就会输出相应的电压和电流,反之给它施加交变电压就会产生相应的变形,即震动。这样陶瓷振荡器在高频电压的带动下产生超声震荡,使水雾化,再通过风扇把水雾送出,达到加湿空气的效果。这好比是我们把一个震荡的音叉放进水里就会使水震荡溅起水花是一样的,只不过超声波雾化头产生的水雾是很细微的,功率也大的多。  超声波加湿器原理  超声波工业加湿机采用电子超频震荡(震荡频率为1.7MHz,超过人的听觉范围,对人体及动物绝无伤害),通过雾化片的高频谐振,将水抛离水面而产生自然飘逸的水雾,不需加热或化学药品而产生1-10μm的水颗粒漂浮于空气中,达到空气湿润效果。同时合适的相对湿度对提高产品质量、降低废品率防静电消除粉尘净化空气和改善环境均具有决定性的作用。  二、加湿器不出雾怎么办  1.加湿器雾化片出现故障。解决方法:打开底盖先检查是否是保险丝烧了,如保险是好的则试着调节电路板上的电位器,顺时针转四分之一圈后试试,如果是加湿器还是不喷雾,则考虑换掉雾化片,一般加湿器的雾化片在喷口下方正对的一个直径约20-30毫米的“金属”圆片,处理时不能用硬物搽刮,一旦金属镀层脱落,换能器将不能正常工作,也就造成了加湿器不出雾。  2.一般加湿器工作有两个条件:1.陶瓷振荡器振动,产生水雾。2.风扇转动,把水雾送出。如果加湿器能够运转但是没有水雾喷出,则有可能就是风扇出现故障。解决方法:太久没用导致风扇卡死了,加点润滑油轻轻的拍打两下,让风扇重新转动。  3.如果加湿器出现不喷雾不喷雾、不出气的情况,最大的原因就是没有对加湿器进行定期清洗保养。一般来说,加湿器的一周左右清洗一次比较好。  以上就是小编为大家介绍的加湿器原理的相关资讯,希望能够帮助到您。更多关于加湿器原理的相关资讯,请继续关注土巴兔学装修。土巴兔在线免费为大家提供“各家装修报价、1-4家本地装修公司、3套装修设计方案”,还有装修避坑攻略!点击此链接:【https://www.to8to.com/yezhu/zxbj-cszy.php?to8to_from=seo_zhidao_m_jiare&wb】,就能免费领取哦~

pope和pontiff有什么不同

The Pope is the Bishop of Rome, a position that makes him the leader of the worldwide Catholic Church.A pontiff was a member of the principal college of priests (Collegium Pontificum).The term "pontiff" was later applied to any high or chief priest and, in ecclesiastical usage, to a bishop and more particularly to the Bishop of Rome, the Pope or "Roman Pontiff".所以原来两者的使用对象是截然不同的,现在看来区别不是很大,但是pope是绝对唯一的职位,而pontiff包含的就广一点。不知道理解的是否完全正确。探讨

为什么转基因技术产生了新基因?它的原理是基因重组 基因重组不是只能出现新的基因型吗

转基因技术是特殊的基因重组一般狭义上的基因重组是发生在同一物种之间,发生在减数分裂的过程之中,通过基因重组,产生不同的基因型,但是所有的基因局限在这一物种之中然而转基因技术可以将其他物种的基因整合到该物种细胞中,目的基因对于该物种而言是新基因。

常见的激光测量仪器有哪些?

u200du200d激光测距仪是利用调制激光的某个参数对目标的距离进行准确测定的仪器。脉冲式激光测距仪是在工作时向目标射出一束或一序列短暂的脉冲激光束,由光电元件接收目标反射的激光束,计时器测定激光束从发射到接收的时间,计算出从测距仪到目标的距离。当发射的激光束功率足够时,测程可达40公里左右甚至更远,激光测距仪可昼夜作业,但空间中有对激光吸收率较高的物质时,其测距的距离和精度会下降。世界上第一台激光器,是由美国休斯飞机公司的科学家梅曼于1960年,首先研制成功的红宝石激光[1]器。美国军方很快就在此基础上开展了对军用激光装置的研究。1961年,第一台军用激光测距仪通过了美国军方论证试验,对此后激光测距仪很快就进入了实用阶段。由于激光测距仪价格不断下调,工业上也逐渐开始使用激光测距仪。国内外出现了一批新型的具有测距快、体积小、性能可靠等优点的微型测距仪,可以广泛应用于工业测控、矿山、港口等领域。u200du200d

人造雪是怎么做的

1、人造雪又称人工造雪,是指人为地,通过一定的设备或物理、化学手段,将水(水气)变成雪花或[1]类似雪花的过程。人造雪制造方式分为炮筒式与冰片粉碎式。自然雪花密度约为328kg/m_,而人造雪密度约为856kg/m_。2、从本质上看,人造雪和自然雪是相同的,但人造雪的密度更大。因此在相同条件下,同体积人造雪比自然雪融化慢。
