昨天上午汤姆牙痛她妈妈带着她去看牙医英语

1. 此题没有具体的上下文,所以答案BC都是可以的. 2. 选B ago,翻译为:然后她妈妈几个小时前带她去牙医的诊所. 选C later,则翻译为:然后她妈妈几个小时后带她去牙医的诊所. a few hours ago“几个小时前”,而a few hours later“几个小时后”. 3. 至于A,only不会放在一段时间之后,翻译也不通顺,排除. D before,如果用a few hours before则要求句子必须使用过去完成时而不是一般过去时,排除. 4. 至于到底选哪一个,需要楼主根据上下文,自行选择. 不过我个人凭直觉判断,答案可能是C,而不是B.

阳台室内升降晾衣架双杆怎么安装

需要找晾衣架安装工可以到我们官网发布任务找晾衣架安装人员,或者自主安装方法如下:升降晾衣架安装方法1、当着客户的面拆开升降晾衣架的外包装,检查无破损后清点晾衣架的零配件,一般零配件有:转角器、定盖、吊环、手摇器、膨胀螺丝、手柄、钢丝绳、楞插、滑轮架。2、首先安装手摇器,在走廊的两端任意一端安装手摇器,测量要需要安装手摇器的位置,一般离地一米二的距离安装,将手摇器摆放在需要安装的位置,然后用标记笔标记好需要打孔固定的孔位,然后挪开手摇器,用电钻打孔,安装膨胀胶塞,并将手摇器固定拧紧;然后把手摇器里面的钢丝绳全部摇出来,摇出钢丝绳的时候,需要牵引钢丝绳,以免乱线,直到手柄转不动为止。3、确定滑轮架安装位置,滑轮架就是安装在天花板的那四个支撑点,靠近转角器这边的是双滑轮架,末端的是单滑轮架,一般以单滑轮架为例,单滑轮架与两边的墙面距离应该大于27公分,而两个单滑轮架之间的距离应该大于45公分,而单滑轮架与双滑轮架之间一般距离为2M,但是最后以安装环境为最终条件。确定好安装位置后标记,并标记孔位,然后在安装孔位上打孔。4、打好孔后,将膨胀螺丝分别与四个滑轮架组装起来,组装如图。5、组装好后将两个双滑轮架与两个单滑轮架分别安装在打好的孔位上。6、将转角器跟膨胀螺丝组装在一起。7、确定转角器安装位置,转角器的位置一定要与手摇器的位置垂直,呈90度。8、确定好安装位置后,就标记打孔,并将组装好的转角器安装好。9、穿钢丝第一步,将钢丝拆包,分别握住里面的两根钢丝的一端,将它们首先穿入转角器中。10、接着将钢丝绳的两端穿过其中一个双滑轮架,两条钢丝绳平行且不要缠绕,把从双滑轮架下面穿出的钢丝绳一端拉到接近手摇器的位置,另一端全部拉过转角器,另一根钢丝绳和前面同样的操作,然后再将手摇器摇出来的钢丝绳一端的扣子,挂至转角器钢丝绳的尾部,另一根同样操作。在装上定盖。11、安装吊环,将刚刚穿好的钢丝4端剪平,然后将其穿过吊环并绑紧。12、安装晾衣杆,将四个吊环分别于两根晾衣杆的两边套好固定。

金派灭菌的环氧乙烷灭菌对金属会造成腐蚀吗?

作用:可以用来杀菌;原理:主要是利用环氧乙烷动分解时能产生巨大能量,能够破坏细菌的内部结构,从而对细菌造成伤害。环氧乙烷的结构式:环氧乙烷是一种有机化合物,化学式是C2H4O,是一种有毒的致癌物质,以前被用来制造杀菌剂。环氧乙烷易燃易爆,不易长途运输,因此有强烈的地域性。被广泛地应用于洗涤,制药,印染等行业。在化工相关产业可作为清洁剂的起始剂。环氧乙烷是继甲醛之后出现的第2代化学消毒剂,至今仍为最好的冷消毒剂之一,也是目前四大低温灭菌技术(低温等离子体、低温甲醛蒸汽、环氧乙烷、戊二醛)最重要的一员。EO是一种简单的环氧化合物,为非特异性烷基化合物,分子式为C2H4O,结构式为:-CH2-CH2-O-。化学性质化学性质非常活泼,能与许多化合物发生开环加成反应。 环氧乙烷能还原硝酸银。受热后易聚合,在有金属盐类或氧的存在下能分解。主要用途:环氧乙烷是一种有毒的致癌物质,以前被用来制造杀菌剂。环氧乙烷易燃易爆,不易长途运输,因此有强烈的地域性。被广泛地应用于洗涤,制药,印染等行业。在化工相关产业可作为清洁剂的起始剂。环氧乙烷有杀菌作用,对金属不腐蚀,无残留气味,可杀灭细菌(及其内孢子)、霉菌及真菌,因此可用于消毒一些不能耐受高温消毒的物品以及材料的气体杀菌剂。作用:可以用来杀菌;原理:主要是利用环氧乙烷动分解时能产生巨大能量,能够破坏细菌的内部结构,从而对细菌造成伤害。环氧乙烷的结构式:环氧乙烷是一种有机化合物,化学式是C2H4O,是一种有毒的致癌物质,以前被用来制造杀菌剂。环氧乙烷易燃易爆,不易长途运输,因此有强烈的地域性。被广泛地应用于洗涤,制药,印染等行业。在化工相关产业可作为清洁剂的起始剂。环氧乙烷是继甲醛之后出现的第2代化学消毒剂,至今仍为最好的冷消毒剂之一,也是目前四大低温灭菌技术(低温等离子体、低温甲醛蒸汽、环氧乙烷、戊二醛)最重要的一员。EO是一种简单的环氧化合物,为非特异性烷基化合物,分子式为C2H4O,结构式为:-CH2-CH2-O-。化学性质化学性质非常活泼,能与许多化合物发生开环加成反应。 环氧乙烷能还原硝酸银。受热后易聚合,在有金属盐类或氧的存在下能分解。主要用途:环氧乙烷是一种有毒的致癌物质,以前被用来制造杀菌剂。环氧乙烷易燃易爆,不易长途运输,因此有强烈的地域性。被广泛地应用于洗涤,制药,印染等行业。在化工相关产业可作为清洁剂的起始剂。环氧乙烷有杀菌作用,对金属不腐蚀,无残留气味,可杀灭细菌(及其内孢子)、霉菌及真菌,因此可用于消毒一些不能耐受高温消毒的物品以及材料的气体杀菌剂。

潮汐发电是利用海洋的什么资源

潮汐发电是利用海洋的动力资源。潮汐发电与普通水力发电原理类似,通过出水库,在涨潮时将海水储存在水库内,以势能的形式保存,然后,在落潮时放出海水,利用高、低潮位之间的落差,推动水轮机旋转,带动发电机发电。潮汐作为一种自然现象,为人类的航海、捕捞和晒盐提供了方便。这种现象主要是由月球、太阳的引潮力以及地球自转效应所造成的。涨潮时,大量海水汹涌而来,具有很大的动能;同时,水位逐渐升高,动能转化为势能。落潮时,海水奔腾而归,水位陆续下降,势能又转化为动能。海水在运动时所具有的动能和势能统称为潮汐能。潮汐是一种蕴藏量极大、取之不尽、用之不竭、不需开采和运输、洁净无污染的可再生能源。建设潮汐电站,不需要移民,不淹没土地,没有环境污染问题,还可以结合潮汐发电发展围垦、水生养殖和海洋化工等综合利用项目。

电热暖手宝里面装的是什么液体 ?能用水替换吗?

电热暖身宝宝里面装的是什么液体?能用水体感吗?你再买这个电热暖心,宝宝肯定有使用说明书啊,他的说明书写的应该很清楚,能不能替换你们的液体,如果没有说可以替换里面的液体,那么你肯定就不要去吃饭了,毕竟这个东西不能胡乱去搞的容易出问题啊,如果搞得不好漏电的话可是非常危险的,所以说如果他写得很清楚不能替换你们的水或者是没有写这个东西可不可以替换,你肯定就不要去替换了,这些东西很危险的,搞得不好就要自己受伤了。

儿童平衡车初学者教程

儿童平衡车初学者教程如下:1、坐:七宝2岁的时候开始平衡车,之前玩过学步车,似乎并没有太大难度,就是手臂力量要锻炼一下控制能力。坐垫高度调至膝盖微弯曲;合适的坐垫高度可以帮助小朋友在骑行中更加舒适,身体向前往下倾压,身体距离车把约十公分左右。2、蹬:蹬这个姿势非常简单,学步的时候就会,当坐上车后,两腿分开,一只脚在前,一只脚在后,前脚脚掌全部着地,后脚脚跟抬起,作准备出发往后蹬的姿势。由于没有踏板,平衡车蹬动时腿部更直用力,所以不但心会影响腿部变形问题。3、握:手臂与车把水平垂直于车把放置,手掌虎口向前,骑行过程中方便用力,也可以根据孩子自己的握力习惯来调节座椅的高度,选择舒适用力的角度把握转头。4、在滑行过程中,手握车把抬头注视前方,身体往前向下倾压,两脚交替左右往后蹬踏滑行,同时使身体保持平衡。平衡车一般指电动平衡车。 电动平衡车,又叫体感车、思维车、摄位车等。市场上主要有独轮和双轮两类。其运作原理主要是建立在一种被称为“动态稳定”(Dynamic Stabilization)的基本原理上。

ABB变频器的直接转矩控制和矢量控制使用体验?

Emerald InsightABB: Direct torque control在这篇文章里,这位ABB市场部经理说,95年以后DTC将构建所有ABB驱动产品。如果这哥们所述没错的话,现在市场上的ABB变频器都应该是基于DTC的,DTC是天然的无位置传感器的控制算法,在这方面它明显优于VC,而且DTC在转矩动态性能上要明显优于VC。VC的优点在于稳态性能要好一些。不过很明显,ABB变频器产品中所用的DTC应该不是传统的滞环加查表,很可能增加了很多的磁链和转矩观测上优化,而且很有可能使用了模型预测控制,个人揣测。注:因为有关VC的定义没有普遍共识,此处所说的VC是通常大家所说的对id,iq电流分别PI调节,然后需要PWM或SVM的调制解调器的矢量控制算法,需要Clark和park变换。

属于烷基化灭菌原理的灭菌方式

应该问的是环氧乙烷。 环氧乙烷是继甲醛之后出现的第2代化学消毒剂,至今仍为最好的冷消毒剂之一,也是目前四大低温灭菌技术(低温等离子体、低温甲醛蒸汽、环氧乙烷、戊二醛)最重要的一员。EO是一种简单的环氧化合物,为非特异性烷基化合物,分子式为C2H4O,结构式为:-CH2-CH2-O-。 环氧乙烷灭菌原理 1、烷基化作用 环氧乙烷杀灭各种微生物的作用机制,主要是烷基化作用,作用的位点是蛋白质和核酸分子中的疏基(-SH)、氨基(-NH2)、羟基(-COOH)和羟基(-OH)等,环氧乙烷可使这些基团发生烷基化反应,使微生物这些生物大分子失去活性,从而致死微生物。 2、抑制生物酶活性 环氧乙烷能抑制微生物各种酶的活性,如磷酸脱氢酶、胆碱脂酶及其他氧化酶等,阻碍了微生物正常代谢过程的完成,导致其死亡。 3、对微生物的杀灭作用 环氧乙烷液体和气体均有较强的杀微生物作用,相比之下,气体的杀微生物作用更强,在消毒灭菌上一般多用其气体。 环氧乙烷属高效广谱灭菌剂,对细菌繁殖体细菌芽胞、真菌、病毒均有强大的杀灭灭活作用。在环氧乙烷与微生物接触,但微生物又含有足够水分的条件下,则环氧乙烷与微生物的作用为典型的一级反应,灭活纯培养微生物的剂量,反应曲线在半对数值上为一直线。 这个规律适用于一切微生物,不同种类的微生物对环氧乙烷的抵抗力有差别,但差别不显著,细菌芽孢对环氧乙烷的抵抗力仅比繁殖体强2倍,未发现由遗传决定对环氧乙烷高度耐药的微生物。细菌芽孢对环氧乙烷的抵抗力较强,其中枯草杆菌黑色变种芽孢为最强。

暖手宝可以重复使用吗?

可以在变冷之后放入热水中进行加热,等待掰掰热暖手宝变成透明色就可以进行二次使用,只要暖手宝不热了就可以放入热水中进行加热,但是不能放入高于60度的水中进行加热。掰掰热暖手宝的原理就是一种物理化学的相变,就是用溶解或者析出过程放热的现象。只要掰掰暖手宝的小铁片,就会产生动量,液体凝固的过程就是动量转化成热量了。不过如果温度过高时,紧贴在皮肤取暖的话,可能会烫伤皮肤。袋里装的是过饱和溶液醋酸钠,掰动里面的金属片其实是应用摩擦消除了过饱和溶液并不稳定的“稳定”状态,使溶液在金属片表面形成微小晶核并迅速生长,消耗溶液中过饱和的那部分溶质,直至溶液进入稳定的饱和状态,这时“暖手宝”就放热了。暖手宝,大致可分为三种:1、用通过加热水来发热的的,也就是我们俗称的热水袋,跟传统的热水袋不同,电热水袋省却了添水的麻烦,只要插上电源等上10几分钟就能发热,实际上是把里面的水煮开,所以一般温度会很高。2、通过化学反应来发热的,市面上的暖手宝就是这种类型的,通过里面化学物质的接触,产生的热量,温度大约40℃左右。3、是使用锂电池功能,内部发热片发热,使用USB接口充放电,跟暖手鼠标垫类似,由于锂电池能充放电的功能,一般也能做为移动电源使用。体积小巧,方便随身携带,温度能达到50℃左右。原理外观:一个密封塑胶袋,里面充满透明液体,液体中放有一个金属片。1、使用——轻轻弯曲袋内金属片,袋中液体即出现结晶状(蓝色半透明),变硬成固体。发热温度50度左右(约1小时)。2、备用——使用后,把其放入沸水煮10分钟,直至结晶体完全恢复成透明液体,冷却后,可再次使用。3、产品可依以上方法反复使用多次。4、在炎热的夏天,可以改做冷宝,像冰袋一样使用、防暑降温,但使用前需要在冰箱里冷冻。以上内容参考:暖手宝

怎样利用潮汐发电?

潮汐能的利用方式主要是发电。潮汐发电是利用海湾、河口等有利地形,建筑水堤,形成水库,以便于大量蓄积海水,并在坝中或坝旁建造水利发电厂房,通过水轮发电机组进行发电。只有出现大潮,能量集中时,并且在地理条件适于建造潮汐电站的地方,从潮汐中提取能量才有可能。虽然这样的场所并不是到处都有,但世界各国都已选定了相当数量的适宜开发潮汐电站的站址。发展像潮汐能这样的新能源,可以间接使大气中的二氧化碳含量的增加速度减慢。潮汐是一种世界性的海平面周期性变化的现象,由于受月亮和太阳这两个万有引力源的作用,海平面每昼夜有两次涨落。潮汐作为一种自然现象,为人类的航海、捕捞和晒盐提供了方便。更值得指出的是,它还可以转变成电能,给人带来光明和动力。据估计,世界海洋的潮汐能约有10亿多千瓦,每年可生产12400亿度电能,尤其在浅海中潮汐能量更大,黄海就有5500万瓦。20世纪50年代以来,各国开始兴建潮汐发电站,目前最大的一座每年发电量为5亿多度。潮汐能的重要应用之一是发电。潮汐发电的原理,和一般水力发电完全相同,就是利用海水涨落及其造成的水位差,来推动水轮机,水轮机再带动发电机发电。
