The control signals of the PWM rectifier are obtained by comparing the current of AC side with triangular wave (or saw-tooth wave) directly, which can implement the steadiness of the voltage of DC side and unit capacity factor of the system. At the same time, harmonic component of the system is abstracted through Instant Reactive Power Method, which can be smoothed by Integrated Learning Boost Converter Control.

本文采用重复学习Boost变换技术，利用滑模变结构控制技术对单相PWM整流器恒频Boost变换进行了分析，提出将交流侧电流直接与三角波相比较得到开关控制信号的方法，实现直流电压恒定不变及系统单位功率因数；同时，利用瞬时无功功率法分析系统谐波，并在谐波域内使用重复学习的控制方法，结合Boost变换技术，有效滤除系统谐波有功电流。

Selective external biliary drainage could improve liver function. It may result from an increase of the future remant volume and the molecular mechanism might be associated with elevation of per volume expression hepatobiliary membrane transporters.

选择性胆管外引流能够改善肝功，一方面与预保留侧肝脏体积代偿性增加有关，另一方面其分子机制可能与开放引流后单位体积的膜转运蛋白表达增高有关； 5。

The head of my school went to the house of detention and persuaded me in an imploring voice,"You should think about the elders even if you don't care about your child. Your father is weeping every day. Falun Gong has done you so great harm, yet you know nothing about that…" However, these words didn't touch my cold-blooded heart.

单位领导到拘留所几乎用哀求的语气劝我&就算你不为孩子想，也该为老人想想，你爸天天哭，'法轮功'把你害成了什么样，你都不知道……&然而，这并没有打动我那冷酷的心。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
