示功器

Damping force can be controlled in one of the two ways,open loop control or force feedback control.

通过特性试验，得到示功特性、速度特性，经转换得到阻尼器的阻尼力——电压模型和阻尼系数——电压模型。

The simulation results show that hysteresis phenomenon of the velocity curve becomes more and more serious,and the area enveloped by the ergogram becomes smaller and smaller with the increase of frequency,indicatin...

从扫频结果可知，速度曲线随频率增加滞回现象越来越严重，示功图所包围的面积随频率增大越来越小，表明工作频率太大不利于减振器特性的发挥。

With that model, the characteristic of the controllable damper can be worked out based on the characteristic curve of the vane damper and proportioning valve separately.

使得通过减振器的示功图曲线和比例阀的工作曲线，就可以得到可控减振器的特性曲线，大大减少了台架试验的次数。

Key words: Heat power system; Vehicle; Indicator card

The system can complete plenty of testing program, such as indicator diagram, speed diagram, friction diagram, temperature attenuation diagram, fatigue life testing, single and double actuator testing, whole frequency testing and so on.

该系统可实现汽车减振器的示功试验、速度试验、磨阻试验、温衰试验、疲劳寿命试验、单双动试验和扫频特性试验，技术先进，功能强大。

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。
