Meanwhile , the measurement error of contact angles caused by the measurement error of droplet height , the bottom diameter of droplet and the turning error of protractor were discussed : Verification experiments were performed and the results obtained are coincident with the theory . Finally , hypsometry is proved to be more precise , faster and more convenient .

从理论上对这2种液滴角度测量法的测量原理和测量误差进行比较分析，分别讨论了液滴高度，底端直径的量取误差和量角器转动误差产生的接触角测量误差，并用实验进行验证，这些实验结论和理论相符，最后证实量高法更准确，快捷，方便。

With this new model man can avoid some unsuitability even illogicality that would occur in some traffic corridor case by using some traditional model such as Logit-model.

该模型从理论上避免了目前一些常用分析理论在某些交通走廊应用的误差较大甚至出现矛盾的现象。

I hope that it will be intelligible to others.

但是，本书的主要目的是探讨理论上的难题，至于该理论在实际中的应用则居于次要地位。

The relationship between the inverse number density of particle of the laser transition levels and the discharge condition such as the discharge current, the He pressure and the temperature of Cd-reservior has been achieved. The discharge condition for obtaining maximum laser output was theoretically achieved.

分析了441.6nm谱线的激发机理及各种粒子的相互作用过程，导出了441.6nm谱线跃迁能级激励的理论模型及其粒子数密度速率方程，得到了粒子反转数密度与放电电流、氦气压强和镉炉温度等放电条件的关系，从理论上，定量得出了获得最大输出功率时的放电条件。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
