一篇简单的科学实验英语作文,实验越简单越好,如梳子梳头产生静电

The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions. Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable. However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce. Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.

怎样让细软的头发蓬松一些

细软的头发要有蓬松感,可以试试以下方法:1、吹发有技巧吹头发应该是顺着毛鳞片,一般都是从上往下吹,这样不容易损伤头发。但是身体直立从上往下吹,吹完后头发会更贴头皮。所以建议细软发质的小伙伴用低头吹的方式。在耳根和脖子建议细软发质的小伙伴用低头吹的方式。在耳根和脖子部位用手将头发掀起来,一边吹一边拨弄头发,这样头发会干得更快。另外,风力越大,吹出来的效果越蓬。吹风机的热风可以用来塑型,冷风则能达到定型的效果,所以建议先用热风让头发快干,然后再用冷风吹。还有一个吹发技巧就是利用斜翻刘海,打造蓬松感。2、蓬松发根的产品针对出油扁塌发质效果好。很多细软发质扁塌是因为头皮出油,如果你是这一类的,可以用免洗喷雾。将头发分层来喷,每次使用喷雾时记得要离头皮在10cm左右的位置,不要靠得太近,除非你想别人以为你长出了一大片头皮屑。还有这类免洗喷雾,蓬蓬粉之类的产品要少用,会堵塞头皮毛孔,头皮不健康头发只会越来越少哦。3、倒梳的方式是最快制造蓬松效果的。倒梳是专业发型师在造型时常用到技巧。先将头顶的头发分成上下两层,用倒梳的方式打乱下面那层,再将上层的头发覆盖被倒梳的部分,最后用定型喷雾将上面的头发做定型。不过倒梳对头发伤害很大,如果要用这种方式,必须选择专业的倒梳梳子(英文是teasing comb)。先按照平时习惯分头发的位置,将头发分出两半。然后用卷发梳和吹风机,将头发向外吹,在发根处定型。吹完后用卷发棒再次定型,别忘记发根也要向上拱着定型一下。2、蓬松发根的产品针对出油扁塌发质效果好。很多细软发质扁塌是因为头皮出油,如果你是这一类的,可以用免洗喷雾。将头发分层来喷,每次使用喷雾时记得要离头皮在10cm左右的位置,不要靠得太近,除非你想别人以为你长出了一大片头皮屑。还有这类免洗喷雾,蓬蓬粉之类的产品要少用,会堵塞头皮毛孔,头皮不健康头发只会越来越少哦。3、倒梳的方式是最快制造蓬松效果的。倒梳是专业发型师在造型时常用到技巧。先将头顶的头发分成上下两层,用倒梳的方式打乱下面那层,再将上层的头发覆盖被倒梳的部分,最后用定型喷雾将上面的头发做定型。不过倒梳对头发伤害很大,如果要用这种方式,必须选择专业的倒梳梳子(英文是teasing comb)。

atox47.5立磨磨盘衬板磨损到什么程度需要更换

立磨磨辊及磨盘衬板材质一般使用高铬铸铁或镍铬合金,而此种材质却时常发生断裂现象,造成的损失是相当严重的,特别是停产的损失,更是无法估计。在此,笔者对于此课题的研讨作一浅述,抛砖引玉,希望各位学者或专家能引起共鸣。 1硬度与断裂 耐磨是我们追求的目标,大家都知道产品越硬则越耐磨,所以要做出较耐磨的磨辊和磨盘好像很简单,因为你只要设法去提高它的硬度即可,故许多铸造厂标榜其铸件含铬量达到30%,HRC硬度达到了63-65,但是事实上并非如此。硬度越高,铸件所含的碳化物(Cr7C3)数量就要求越多,分布越弥散,在基体和碳化物的界面上形成微孔洞和微裂纹的几率就越大,同时断裂的几率也会越大。而且越硬的物品越难切削加工。因此铸造出既耐磨又不易断裂的产品就不是想象的那么简单。 相关资料:碳和铬的主要作用是保证铸铁中碳化物的数量和形态。随着C量提高,碳化物增多;随着Cr/C比的增加,共晶碳化物的形貌经历了由连续网状→片状→杆状连续程度减小的过程,共晶碳化物晶格类型经历由M3C→M3C+ M7C3→M7C3的变化过程。有资料指出:当共晶碳化物不变,且Cr/C为6.6~7.1时,高铬铸铁的断裂韧性值(即K1c值)最高,亦即此时抗裂纹扩展能力最强。根据这些原理,宜将C量定为3.1%~3.6%, Cr量为20%~25%。 2热处理与断裂 我们知道提高高铬铸铁硬度的另一个重要因素:热处理。我们用高铬铸铁(或镍铬合金)铸成磨辊或磨盘衬板,经过热处理来提升其铸件硬度,但检测时将会发现铸件硬度各点位置的硬度值差别会较大,热处理技术就是主要原因。如果铸造及热处理工艺越理想,则其硬度差异越小,反之则越大,而硬度差异越大,则铸件断裂的几率也越大。且铸件体积越大,热处理越难。按国际惯例,一般判断高铬铸件是否易断裂的方式就是:铸件表面对称取几点检测硬度值,当HV硬度差值超过30,即此高铬铸件为不合格,较易发生断裂的危险。 相关资料:高铬铸铁基体组织里含马氏体和奥氏体,马氏体组织硬度高,奥氏体韧性好。铸件随着热处理时冷却速度的加快,奥氏体转变成马氏体更完全,残余奥氏体量更少,所以高铬铸铁的硬度越高,而抗冲击疲劳能力变差。同时,冷却速度越快,裂纹萌生的几率愈大,结果使材料的抗冲击疲劳能力下降,所以热处理时宜采用冷却速度较慢的方式。 3机器运转与断裂 铸件的应力与粉磨的挤压载荷易使马氏体组织产生裂纹,当共晶碳化物沿晶界析出成网状,因其脆性会促进裂纹扩展,残留奥氏体的存在此时很好的阻止了裂纹的延伸。由于立磨实际运转时其工况相当复杂,粉磨的物料中存在有较硬较大的异物(如铁块)时,立磨磨轮与磨盘衬板在物料粉磨挤压受到的挤压就加大,当载荷超出了奥氏体组织承载范围,此时高铬铸件就易发生断裂的危险。一般水泥企业立磨检修的时间都比较紧张,希望停机时间越短越好,因此,当停机后都直接打开磨门来降低磨内温度。却不知,高铬铸件不宜此种方式的急速冷却,冷却速度越快,裂纹萌生的几率愈大,也有可能直接产生铸件断裂。 立磨(www.sbmlimoji.net)磨轮和磨盘衬板的断裂原因较复杂,在此不一一列举,作为硬面耐磨堆焊领域的领头军,我公司在此方面作出了各种尝试,最终认为要真正解决断裂的风险问题,以复合制造的方式最安全,即高拉力钢铸造+耐磨堆焊。优点如下: (1)制造加工方便快捷; (2)避免断裂风险; (3)耐磨性能卓越; (4)性价比最优。 虽然复合制造有诸多优点,但若无成熟的技术和经验,亦会发生一系列的问题。 铸造基体必须选用优质的材料和成熟的铸造工艺,保证基体的焊接可靠性。绝不允许基体内部空洞、沙孔、气孔等影响铸件质量的问题存在。 加工亦须谨慎,研讨出最佳的加工设计尺寸,选择精度较高的数控机床加工及合适的加工方案来保证产品的尺寸,以免发生装配不符的情况。 堆焊尤为重要。选用合适且耐磨的焊丝是首要条件,否则会直接影响产品的使用寿命。成熟的堆焊技术保证焊接的牢固度及耐磨性能,达到产品的最佳使用效果。避免因随意堆焊而造成焊层脱落的情况发生,给企业带来不必要的损失。 4结束语 如何避免断裂风险及选用合适的制造方式,仅以此文作一浅述,希望使用单位能得以警惕,安全生产,防止断裂事故的发生

英语道歉信格式怎么写

Dear David:I am afraid that you will think me unpardonably negligent in nothaving answered your letter dated 7, December sooner, but when I have told you the reason, I trust you will be convinced that the neglect was excusable. When your letter arrived, I was just in Hong Kong. As my family could not forward it to me during my absence, it has been, therefore, lying on my desk until the moment when I took it up. Now the first thing I have to hasten to do is to write to you these few lines to express my deep regret.I enjoyed many pleasant sights during my trip. I shall be pleased to give you an account to of them when I see you next.Sincerely yours,Tom

生命的意义在哪

生命的意义是一个非常深刻和复杂的问题,每个人的答案可能都不同。对于一些人来说,生命的意义可能是追求个人幸福和满足。对于其他人来说,生命的意义可能在于为家庭和社区做出贡献,为他人的生活带来积极的影响。还有些人可能认为生命的意义在于追求知识、智慧和心灵的成长,不断探求自我意识和宇宙的奥秘。不管每个人对生命意义的理解是什么,都需要理解到这是一个主观的问题,不同人的回答可能并不相同。生命的意义容易受到社会和文化背景、个人价值观、信仰和个人历史背景等因素的影响。因此,思考生命的意义时,需要从自己的角度出发,考虑自己的目标、价值和信仰,以便理解和找到生命的真正意义。

Sanger 双脱氧法测序原理,简述测序技术发展趋势

DNA链中的核苷酸是以3`,5`-磷酸二酯键相连接,合成DNA所用的底物是2`-脱氧核苷三磷酸(dNTP),在Sanger 双脱氧链终止法中被掺入了2`,3`-双脱氧核苷三磷酸(ddNTP),当ddNTP位于链延伸末端时, 由于它没有3`- OH,不能再与其它的脱氧核苷酸形成3′,5′-磷酸二酯键,DNA合成便在此处终止,如果此处掺入的是一个ddATP,则新生链的末端就是A,依次类推可以通过掺入ddTTP、 ddCTP、 ddGTP ,则新生链的末端为T、C或G,根据这个原理,Sanger与1977年建立了双脱氧链终止测序法。他本人也因此而获得了诺贝尔奖。以单链或双链DNA为模板,采用DNA引物引导新生DNA的合成,因此又称为引物合成法,或酶促引物合成法。主要是基于DNA聚合酶的催化特性:①以DNA为模板,根据碱基配对的原则逐个将dNTP加到与模板结合的寡核苷酸引物的3′-OH末端,形成正确的模板DNA互补链;②能以dNTP作为底物,也能利用ddNTP作底物,将其掺入寡核苷酸链的3 ′末端而终止新生互补链的延伸。如果在DNA的合成反应中,除了加入4种正常的脱氧核苷三磷酸(dNTP)外,再加入一种少量的2ˊ,3ˊ ddNTP,那么多核苷酸链的延伸将与偶然发生但却十分特异的链终止展开竞争,所以反应产物是一系列的长短不一的核苷酸链。 在4组独立的DNA合成反应中,分别加入4种不同的ddNTP,结果将生成4组核苷酸链,它们将分别(随机)终止于每一个A,每一个G,每一个C,每一个T的位置上。对这4组核苷酸链进行聚丙烯酰胺凝胶电泳,就可读出序列。测序现在是第二代技术为主,454,solexa,solid等等,以后将基于纳米技术,进行单分子测序比如隧道探针法等
