First, you should place the Class D amplifier close to the speaker. In the case of stereo applications, you should use two monophonic amplifiers rather than a single stereo chip, so that you can place the two amplifiers next to the two speakers, usually at the sides of the handset.

首先，您应将D级音频放大器放在接近扬声器的位置，在采用立体声效果的时候，您应使用两个单声道音频放大器而非一个单独的立体声放大器，以便您可将两台音频放大器分别放在挨近两个扬声器的位置，通常是放在手机两侧。

According to the characteristics of track correlation and basic principles of data association, a track correlation algorithm is presented for sensor level track fusion systems.

本文第三章比较了传感器级融合结构的航迹关联与单传感器数据关联的特点，研究了经典数据关联方法的基本思想。

For the single-loop, we can relax the control intensity to get better stability; the cascade loop, deputy circuit the need for better self-stability of the rapid response and in order to follow the main circuit changes.

对于单回路而言，可以放宽控制强度得到较好的稳定性；而串级回路中，副回路需要较好的快速响应及自我稳定性才能跟随主回路的变化。

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。
