Potassium is essential for life and is present in all soils. Potassium ions (K+)and sodium ions act at cell membranes in electrochemical impulse transmission and in transport. Potassium in compounds has valence 1. The chloride is used as a fertilizer and a raw material for producing other compounds, and the hydroxide for making liquid soaps and detergents and in preparing various salts.

钾是生命活动必须的，存在于各种土壤中。在电化学脉冲传输和输导过程中钾离子(K+)和钠离子在细胞膜上起作用。钾在化合物中的原子价是1。钾的氯化物用作肥料以及生产其它化合物的原料。氢氧化钾用于制造液体肥皂和洗涤剂，并用于制备各种盐。

There is only so much capital to be gathered, allocated and made liquid, and only so much risk to be parcelled out.

因为总共只有那么多的资本需要被聚拢、配置与流通，也只有那么多的风险需要分散。

2. To cause a liquid to flow or move out of someone or something. In this usage, a noun or pronoun can be used between “drain” and “from.” I had to drain the broth from the noodles, or else my daughter wouldn’t eat the soup.Ever since that football injury, I have to go to the doctor every so often to get fluid drained from my knee.drain from (someone or something)

2.使液体流动或从某人或某物中流出。 在这种用法中，可以在“ drain”和“ from”之间使用名词或代词。 我得把面条里的肉汤倒掉，否则我女儿不会喝汤的。自从那次足球比赛受伤后，我不得不经常去看医生，以排出膝盖里的积液。从（某人或某物）中流出

26.4
Anomalies, Crisis, and Revolution
Normal science prospers under a paradigm. It is the routine science of the day until it encounters difficulties, which Kuhn calls anomalies. The concept of an anomaly (to a paradigm) is rather vague. In its weakest and vaguest sense, it means some sort of difficulty. However, it is often taken as an empirical phenomenon that shows that the paradgigm theory is incorrect, even though no theories are, strictly speaking, falsifiable according to the Duhen-Qunie...

26.4 异象，危机和革命
符合范式的常态科学兴起。在其遇到困难之前，它都是时下的常规科学，库恩称之为异象。异象（相对范式来说）的概念是非常含糊的。在其无力而含糊的含义里，它就意味着某类困难。然而，虽然通常它被视为一种能够证明范式理论是错误的经验主义现象，但是根据Duhen-Qunie理论（第9章），并没有严格说出能够证实的理论依据。作为一般理论的范式理论根本无法作证。曾经说起过这个问题，让我尽量用一个实例来阐明该异象的概念吧。
在1774年，普里斯特利（1733-1804） 用以下化学反应做过实验：
他将液汞在空气中加热，然后它变成了一种红色粉末，即通常所说的红色水银烧渣。当将烧渣继续加热到更高温度的时候，它又变回成水银。
在1775年，拉瓦锡重复做了普里斯特利的实验。却发现了另外一个现象：就是水银衍生出比烧渣更轻的烧渣。换句话说，就是当水银在实验的最初阶段里变成烧渣的时候，它...

It is very important that this second liquid be less dense than (or visa versa), and miscible with, the solvent.

visa versa就是反之亦然的意思,没有错,本网站上也可以查到!这里的比较级是同时比较dense和miscible的.
我的理解是:

这种溶液密度比该溶剂底,易于互溶(反之亦然,即:如果这种溶液密度比该溶剂高,就难于互溶),了解这一点很重要。

个人觉得second没有必要译出,供参考.

A simpler arrangement than that shown at Fig 11.11 is to allow the heated liquid polymer to flow under the force of gravity into the mould through suitably placed gates.

比图表11.11展示更为简洁的做法是：允许加热过的液体聚合物在重力的作用下正好通过设置好的闸门流到模具里。

An excess of 6% of the net amount of liquid required for each component shall also be furnished by party A as spare, except for transformers where 8% of the net amount shall be spare.

泡沫嵌垫（条，片，，团。。请根据具体的形状选用不同的名称）

请在加入餐具洗涤剂的热水中清洗泡沫嵌垫。用力拧干嵌垫，确保里面不含有任何可引致火灾风险或余垢的易燃液体（如汽油）。

用湿布除去滤气器盖上所有的污垢。确保汽化器上没有污垢。
把两个过滤器嵌条放置到原位，确保将它们固定到正确的位置。把过滤器盖盖好并用螺丝固定。
油门扳机
将油门扳机恢复原位。检查扳机是否可以扣动自如—可以用一根手指控制扳机。如果扳机的阻力过大，可以松开油门线上的紧固螺帽，调整螺丝钉，以使扳机的阻力达到所需的程度。然后，拧紧紧固螺帽。
启动发动机，将开关转到“停”(stop), 查看发动机是否会停转。根据需要调整调整油门线。

Can’t Get Enough Sleep? Try Banana Tea

It is no news that a lot of people are suffering from insomnia and getting any kind of sleep has become a big deal to them. It must really be hard on them to be sincere. After going through all the non-stop actions at the various places of work, the right thing for a healthy living is to get home, take a few bites of your favorite meal for dinner and get on the bed and doze off, until the next morning. When this is not the case for anyone, it could be hard...

如果你总是感觉睡眠不足，可试试喝一点香蕉茶。
大家都知道，许多人经常会失眠，对他们来说不管什么形式，只要能睡上一觉就是一件大事。但说实话他们实在太难做到了。在工作场所经过紧张而又马不停蹄的工作后，健康生活的正确方式是回家，吃一点自己喜欢的晚餐，然后上床酣睡，直到第二天天亮。如果有人的情况不是如此，那就很难说了，睡眠不足会导致工作效率不高，甚至会出现严重的健康问题。
我知道你过去可能曾经尝试过一些解决方法，有一些可能有些效果，其他的方法可能根本没有任何作用。如果你想寻找一种完美的解决方法，没有任何副作用，又不会给你添乱，祝贺你了！这里你找到了你要的方法。你应该知道香蕉吧（谁不知道呢？），也知道它的天然特性。但也许你不知道的是香蕉中含有一些你多年来一直在寻找，而又未找到的天然成分。喝上一点香蕉茶，一定会彻底解决你的睡眠问题。香蕉茶利用香蕉中的天然元素，如钾，镁和维生素B6，来调节控制睡眠的...

Burns and blisters
In our research we have found that while burns and scalds are some of the most common injuries affecting babies, they are also the ones that receive incorrect first-aid treatment most frequently. Babies learn by exploring, which involves climbing, touching, tasting and pulling things. One of the most common causes of scalds in the home is a baby that pulls a hot drink onto himself. Even if the drink contains milk and does not feel hot to an adult if can still cause significant...

烧伤和水疱
在我们所研究的受害婴儿中，我们发现烧伤和烫伤是最常见的，他们也是最常接受错误的急救治疗。婴儿是通过探测性进行学习的，包括爬行，触摸，品尝和拖拉物品。其中在家里烫伤的一个最常见的原因就是宝宝将热饮弄到到自己身上。虽然饮料包括牛奶在内，对成人来说也许并不会感觉很热，但对婴儿敏感的肌肤来说却能造成重大伤害。明确的预防总比治疗要好，将热饮，茶壶，咖啡壶，炖锅和各种器具放在婴儿无法触摸到的地方。
将婴儿放入太热的浴水里也是一个烫伤的常见原因。无论何时，在给婴儿沐浴前一定要试试水温，如果不能确定水温的话，可以使用浴盆温度计测量水温。
你的供暖散热器也会对婴儿产生烧伤的危险。你的宝宝还小并不知道你墙壁上那冰冷的东西是什么，当他站起来的时候，发现那玩意确实很有用，但也可能是非常热的。我们都知道，婴儿摔倒在散热器上会造成重大伤害。因此为你的散热器安装温度控制阀或者散热器保护，是可以避免此类...
