变宽

This paper discusses the pulse-width modulation switch sequence of arbitrary-number-level inverters, and proposes a switch sequence with loss balance of power electronic devices.

讨论任意电平逆变器脉宽调制(pulse-width modulation，PWM)序列，提出一种电力电子器件损耗均匀分配的序列方式。

The sampling of the inductor current is synchronized with the PWM signal in synchronous buck converter for both turn-on and turn-off.

在降压转换器中，开关切换时电感电流的取样讯号将会与脉宽调变(pulse width modulation， PWM)讯号同步。

Because of the large MEC in a wide temperature range, these compounds are expected to be the potential candidate for magnetic refrigerants.

由於这种化合物在较宽温区内具有可观的磁熵变，也探讨了它用作近室温磁制冷工质的可能性。

of designing an achromatic lens with F/#=1 and aperture D=5mm is developed and numerical simulation is performed.

利用这种特性，本文提出了一种变深度亚波长孔阵金属折衍混合透镜（DV- SHAM R/D lens），它是由DV- SHAM lens与折射透镜结合，能够消色差，实现宽波段成像。

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。
