In this paper, dry-type transformers 10kV-circuit the development of a load voltage change-over switch, which uses advanced power electronics and opto-mechatronics technology, with the non-excitation voltage regulating transformer is converted to on-load tap changer functions, solve of the non-excitation voltage transformer without power interruption can not adjust voltage, voltage regulator is not convenient, and the shortcomings in time, and have the best communication interface

本文针对10kV 无励磁干式变压器研制一种有载调压转换开关，它采用先进的电力电子技术和光机电一体化技术，具有把无励磁调压变压器转换为有载调压变压器的功能，彻底解决了无励磁调压变压器不停电不能调整电压、调压不方便和调压不及时的弊病，并具备完善的通信接口，可方便地嵌入配电系统的电压无功控制和电力监控中，提高了变压器供电系统的自动化水平。

I would thou couldst ; for who would bear the whips and scorns of time , the oppressor s wrong , the proud man s contumely , the law s delay , and the quietus which his pangs might take , in the dead waste and middle of the night , when churchyards yawn in customary suits of solemn black , but that the undiscovered country from whose bourne no traveler returns , breathes forth contagion on the world , and thus the native hue of resolution , like the poor cat i the adage , is sicklied o er with care , and all the clouds that lowered o er our housetops , with this regard their currents turn awry , and lose the name of action

但愿您做得到谁愿忍受人世的鞭挞和嘲弄，压迫者的虐待，傲慢者的凌辱，法律的拖延，和痛苦可能带来的解脱，在这夜半死寂的荒凉里，墓穴洞开，礼俗的黑色丧服，一片阴森。但是那世人有去无还的冥界，正向人间喷出毒气阵阵，因此那刚毅的本色，象古语所说的那只可怜的小猫，就被烦恼蒙上了一层病容，一切压在我们屋顶上的阴云，因此改变了漂浮的方向，失去了行动的力量。那正是功德无量。

I would thou couldst; For who would bear the whips and scorns of time, The oppressor's wrong, the proud man's contumely, The law's delay, and the quietus which his pangs might take, In the dead waste and middle of the night, when churchyards yawn In customary suits of solemn black, But that the undiscovered country from whose bourne no traveler returns, Breathes forth contagion on the world, And thus the native hue of resolution, like the poor cat i' the adage, Is sicklied o'er with care, And all the clouds that lowered o'er our housetops, With this regard their currents turn awry, And lose the name of action.

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
