损耗

Such a makeup allows the sliding part to be supplied with oil through groove (144), increasing efficiency owing to high sealability and a low sliding loss.

这样的结构可通过槽(144)向滑动部件提供机油，由于具有较高密封性和较低滑动损耗，提高了其效率。

We also got the character of alumina sols and the processing for fabricating compact alumina film. At last, We used SJ-CO_2 laser system to test the loss of the hollow fiber.

同时对氧化铝溶胶的性质和致密氧化铝膜的制备工艺进行了研究，并对成品光纤进行了传输损耗的测试。

And periodic regeneration of dark solitons is not influenced by the interaction.

并且，这种再生效应对损耗和有限的扰动等不敏感。

Nowadays the snubbers in IGBT inverters are traditional clamp RCD snubbers yet, which can convert some energy back to power supply so that the dissipation is low.

目前，在实际IGBT逆变桥电路中，缓冲电路大多还是传统的钳位式RCD缓冲电路，这种电路可以把能量部分回馈电源，故损耗相对较小。

The methods to achieving balanced current are presented and simulated in this paper. Thirdly, the snubbers are designed to compress the switching voltage transient. When IGBT is abruptly turned off, trapped energy in the circuit stray inductance is dissipated in IGBT, causing a voltage overshoot and damaging IGBT.

针对IGBT工作过程中出现的电压尖峰、电流尖峰和大的开关损耗问题，本文首先从理论上详细分析了IGBT逆变桥缓冲电路的工作原理，推导出缓冲电路各元件的参数计算公式，讨论了缓冲电路各元件参数对关断电压波形的影响并进行了仿真分析。

Therefore,taking losses and torque ripple into account,the open-phase operation should be avoided as far as possible even though the motor is at light loads.

因此，从减小损耗与转矩波动两方面考虑，自起动稀土永磁电机即使轻载工况下也应尽量避免断相运行。

In the case of scarce practical data and priori knowledge,modeling of the transmission loss of HF skywave to give guidance to the practical system is a very difficult problem in communication countermeasure simulation system.

Therefore, low loss and low cost microwave phase shifters are required to improve performance and reduce the cost of phase arrays to ensure widespread application.

因此，低损耗，低成本的微波移相器起到了改善相控阵的性能，降低其成本的重要作用，这样相控阵才能得以广泛使用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
