This topic returns in view of the cut type switch spreads the type switch "to return for the predecessor design spreads the type electric power switch utilization in the LED lamps and lanterns" is the research direction, to achieve take reduces the power loss to replace the tradition operational amplifier pulse wave width accent as the goal using IC UC3842 changes part, the actuation returns spreads the type electric power switch's switch of Power MOSFET, so as to controls instead spreads the type electric power switch breakover closure's time then control voltage output size, achieves the output voltage to the load LED lamps and lanterns adjusts the LED lamps and lanterns brightness the goal.

各位大大抱歉~！因为英文底子不好！希望大家帮忙翻译一下，希望不要用翻译软体翻的最好是自己翻！拜托了！本专题针对切换式转换器的返驰式转换器为前身设计「返驰式电力转换器运用在LED灯具」为研究方向，为达到以减少功率损失为目的利用IC UC3842代替传统运算放大器脉波宽度调变部分，驱动返驰式电力转换器的Power MOSFET之开关，藉以控制反驰式电力转换器导通截止的时间进而控制电压输出的大小，输出电压至负载LED灯具达成调节LED灯具亮度的目的。

With a testing system,guided wave testing was carried out on the rock bolts which was free and embedded in the soil to inspect the length of rock bolts.

分析了自由钢杆与置于土壤中钢杆的频散曲线，并利用所建立的试验系统，采用导波技术，对上述两种锚杆的长度进行了检测。

This paper is the continuance of that of Lewalle (2001). Lewalle has made use of Gaussian wavelet to obtain the N-S equations with flexion as fundamental quantity in the infinite domain. In that work, Lapalace operator has been degraded to one-order operator. Moreover the resulted N-S equations take the form of diffusion equations with local bilinear mutual interaction kernel.

本文是Lewalle工作的继续，Lewalle利用高斯子波，得到了以弯曲度为基本量的无穷域中N-S方程，此时Lapalace算子降低为一阶导数，并且N-S方程变形为具有局部化双线性相互作用的扩散方程的形式。

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.
