在抽油杆柱波动方程分离变量法的基础上，将矩阵递推技术与三角级数递推技术相结合，提出了有杆抽油系统故障诊断技术中计算泵功图的一种快速算法，这种方法不仅适用于单级抽油杆采油系统，同时也适用于不同材质、不同杆径抽油杆组成的抽油系统。

The influences of solvent to oil ra-tio, temperature and the composition of the sulfur compounds on the desulfurization of a simulated FCC naphtha con-sisting of n-octane, thiophene and benzothiophene by single-stage solvent extraction were studied first.

以PEG-400为萃取剂，研究了由正辛烷、噻吩、苯并噻吩构成的汽油模拟体系，考察了单级萃取中溶剂比、温度和硫化物组成对分配系数和脱硫率的影响，在剂油比为1时，对模拟体系的脱硫率可以达到64.2％。

The continuous ethanol production with complete distillage recycle was availiable for a certain period provided that the dilution rate was controlled below 0.35 h-1, while an ethanol concentration and productivity of 63 g/L and 22.1 g/ could be achieved by this continuous fermentation system.

研究了用酒精滤液代替原来的工艺用水进行细菌酒精连续发酵试验的可行性；建立了单级无回流连续发酵系统，在稀释率为0.35 h-1时，酒精产量为 64.0 g/L，发酵强度达到22.4 g/；考察了回流比分别为0.5，1.0，稀释率为0.3，0.35，0.4 h-1时，滤液回流对连续发酵系统的影响。

Single-rotational inserted pendulum RIP is a representatively nonlinear unstable object and physical model with broad application fields .

单级旋转倒立摆系统是一种典型的非线性，不稳定的控制对象和广泛应用的物理模型。

As a result, at temperatures from 0.6 to 2 Kelvin, the strings are visible and have magnetic monopoles at their ends.

最后的结果，温度在0.6k到2k之间，弦是可以被看见的，而且在他们的尾部就是磁单级子。

Thus,theexample above demonstrates that a 4 valve with a singlestagedrilled hole cage can achieve a low noise level despite thefactthat the time exit velocity head is much great than the 480kPalimitations that some valve manufacturers advocate.

因此，上例显示了4的单级笼式套筒阀可以实现低噪音，尽管阀门内件节流出口速度头远超过480KPa。这就是一些厂家主张的这个方法的局限性。

Thirdly, A new topology of Single Stage Asymmetrical Half-Bridge Converter with Synchronous Rectification is presented in this paper. The operation principle of the circuit is analyzed in detail. The operation principle of soft-switching and steady-state analysis is proposed.

提出了一种同步整流单级不对称半桥变换电路，对电路的工作原理作了详细的分析，特别是电路的软开关工作过程，并对电路做了稳态分析； 4。

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.

交际能力和语法的关系应该是目标与途径的关系。
