对单级浸取、多级错流浸取和连续逆流浸取进行了试验比较，并结合废次烟叶浸取的特点，设计出一种连续逆流浸取器，并研究了该装置的操作参数对浸取率的影响。

Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic north pole or south pole.

磁单级子是一个被物理学家假设出来的粒子，他携带这一个单独的磁极，无论是南极还是北极。

Through analyzing the double closed-loop control mathematical model of single inverted pendulum, the fuzzy control theory was adopted to carry out computer simulation for inverted pendulum.

通过对单级倒立摆的双闭环的控制数学模型的分析，采用模糊控制理论对倒立摆的控制系统进行计算机仿真。

This paper deduces the mathematical model of a single-inverted pendulum system by Lagrange equation and designs its controller by the adaptive fuzzy method, later, combining its model and controller in Matlab simulation and operating it.

根据Lagrange方程建立了单级倒立摆系统的数学模型，利用模糊自适应控制算法设计了倒立摆系统的控制器，并在Matlab的仿真模块中将倒立摆系统的数学模型和控制器结合起来。

In addition, these oils tend to be of significantly higher quality than mono -grade oils.

除了上面提到的特点以外，这些润滑的质量也明显好于单级润滑油。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
