According to the LC-P line of each of insecticide in the mixture and the formula of co-toxicity factor, several expected mortality and the region of additive action (expected mortality±20% expected mortality) were calculated, and according to observed mortality of mixture, the 95% confidence interval was calculated, LC-P line of expected mortality with the region of additive action and LC-P line of observed mortality with the 95% confidence interval were drawn, it was found that there was overlap between the region of additive action and 95% confidence interval and two lines crossed each other when co-toxicity coefficient was more than 100 and the co-toxicity factor was less than 20, which meant there was no significant differences between expected mortality and observed mortality, and that there was on or a few overlap between the region of additive action and 95% confidence interval when co-toxicity coefficient was more than 100 and the co-toxicity factor was more than 20 or co-toxicity coefficient was less than 100 and the co-toxicity factor was less than 20, which meant there was significant differences between expected mortality and observed mortality.

根据单剂的LC-P线和共毒因子公式，求出混剂的期望死亡率和"相加作用区间"（期望死亡率±20%期望死亡率），根据混剂的实测死亡率求出95%置信区间，画出期望LC-P线及"相加作用区间"和实测LC-P线及"95%置信区间"，发现当共毒系数大于100、共毒因子小于20时，实测LC-P线和期望LC-P线彼此交缠，期望LC-P线的"相加作用区间"和实测LC-P线的"95%置信区间"能高度重叠，表明两条LC-P线之间没有毒力差异；当共毒系数大于100、共毒因子大于20，或者共毒系数小于100、共毒因子小于-20时，实测LC-P线的"95%置信区间"和期望LC-P线的"相加作用区间"只有少量重叠或完全不重叠，体现出了实测LC-P线和期望LC-P线对供试害虫的毒力差异。

The principle of constant power drive is: PD converts the change of output light power of laser diode into the change of diode current, and the change of current is feed back to voltage-current converser which adjusts output current of driver to compensate the laser diode.

这样，当激光器的输出光功率衰减时，驱动器相应的增大输出电流；当激光器的输出光功率增强时，驱动器就相应减小输出电流。对许多激光器应用来说，最希望脉冲输出，因为脉冲输出只有极小的结发热。

I have only to lament, that, when the bitterness of death was past, I was inhumanly brought back to life and misery.

ref沃斯通克拉夫特曾在理性上仔细考虑了她的自杀行为，并在获救-{zh-hans：后；zh-hant：後}-写成文字：当死亡的阴影过去，当我被毫无人道地拉回人世间的痛苦时，我只有选择悲伤。

When Christians sacrifice the uniqueness of Christ in the name of tolerance, when we think there is no absolute but all are relative, then there is no need for encouragement and instruction from God's word.

当基督徒们借者容忍的名义而牺牲掉神的唯一性的时候，当我们认为只有相对而没有绝对的时候，那我们也就不需要神的话的鼓励很和教导了。

It is recommended that such a promise as that to which I have referred, should be enforceable in law even though no consideration for it has been given by the promisee.

我被使～满意，当它被做的时候诺言被所有党了解了不料竟会在情况获胜之下应用，即，当公寓只有部份地被让的时候，而且它超过那没有扩充更进一步了。

As he watched her recorded testimonial and listened to her voice floating across the wood-panelled courtroom, he was facing away from the public gallery where two or three people were sitting.

当他看着女儿的证词，当他听着她的声音木质板材装饰的法庭里飘扬的时候，他把脸转向了只有两三个人的旁听席。

In the main, Cup Finals will only be riotously incident-packed when the weather introduces a random element (for example, the teeming rain that got inside David Elleray's brain in 1994, eventually reducing that occasion to a travesty) or when they involve silly teams.

大体上，杯赛决赛会像暴乱一样地充满着精彩镜头的情况就只有：当天气成为一个随机的要素（例如：在1994年那场冲进大卫。埃勒雷的脑袋里的超级暴雨，最终逼使那场盛事变成一场滑稽的喜剧），或当参赛队伍包括了糊里糊涂的球队（像西汉姆、米尔沃尔等等）。

"In the sudden silence as I finished playing, I looked up to a circle of grim, expressionless faces. Father Brown rose to his feet, and his somnolent voice echoed throughout the silent Temple Hall."......"Instead of the grateful joy that I expected, they were words of quiet rejection! Instead of praise, sullen dismissal. I watched in shock and horror as Father Brown ground my precious instrument to splinters beneath his feet..."

当我结束了弹奏，殿堂一阵宁静，周遭的阴森气息让我望闻生畏，布朗神父面无表情，举起他的脚，深沉的声音在沉寂的殿堂中回荡，看不见我所期待的喜悦只有沉默的回绝，不悦的打发取代了赞美，当我望著神父，将我心爱的乐器在他脚下被踩成了碎片，我一阵错愕与惊悚！

And when she buries a Man, that action concernes me: All mankinde is of one Author, and is one volume; when one Man dies, one Chapter is not torne out of the booke, but translated into a better language; and every Chapter must be so translated; God emploies several translators; some peeces are translated by age, some by sicknesse, some by warre, some by justice; but Gods hand is in every translation; and his hand shall binde up all our scattered leaves againe, for that Librarie where every booke shall lie open to one another: As therefore the Bell that rings to a Sermon, calls not upon the Preacher onely, but upon the Congregation to come; so this Bell calls us all: but how much more mee, who am brought so neere the doore by this sicknesse.

当教堂埋葬了一个人，这个行为亦涉及到我：芸芸众生，可看作一卷书籍，其作者只有一个；当一个人死去，代表他的那一章并没有从书中撕去，而是被翻译成一种更好的语言；书中的每一章都会被这样译成更好的语言；上帝雇佣了几个翻译家；有的章节由"年迈"翻译，有的由"疾病"翻译，有的由"战祸"翻译，还有的由"司法"来翻译；不过在所有的译作里都看得见上帝的手；他的手把我们全部散落的书页又重新装订在一起，送回图书馆，那儿，每本书相互敞开，一本挨着一本放好：所以，正如宣布讲道开始的钟声不仅呼唤讲道者开讲，也呼唤信众来听讲一样，这口丧钟呼唤的是我们大家：尤其是呼唤我，呼唤我这个被疾病带到离门口如此之近的人。

I felt the undulations of the trilobite as it flew to its base, amused myself by remembering the things we called "pill bugs" when Mark and I were eight, wood lice, how if you touched their underbellies they balled tightly and rolled around your hands with only the hard shell exposed.

当它对它的基础飞的时候，我感觉了三叶虫的波动，愉快的我自己藉由记得我们呼叫了"药丸虫"的事物当马克和我是八的时候，木材 lice，如何如果你接触他们紧紧地球而且在和只有难的贝壳你手的周围卷的他们下腹部的暴露。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
