恒定

we use magnetron sputtering to deposit Al-AlN particle film as SED's electron-emitter. The Cr-Cu-Cr electrode was prepared by electron beam vaporize deposition. The voltage used to electroform the cracks are periodic trigonal wave and the breadth of the voltage are increasing gradually.

文章中采用铝-氮化铝薄膜材料作为SED器件的电子发射层，采用磁控溅射的方法镀电子发射层，采用电子束蒸发的方法镀铬-铜-铬材料作为电极；电形成过程中采用电压幅值恒定、周期性重复的脉冲和电压幅值渐增的电压脉冲作为电极电压。

Well, the α ratio works similarly: if emitter current is held constant, collector current will remain at a stable, regulated value so long as the transistor has enough collector-to-emitter voltage drop to maintain it in its active mode.

系数α的作用与之类似：如果发射极电流保持恒定，只要集电极－发射极电压足以使其保持在放大区，集电极电流也将稳定保持。

Slow and consant rotation does not emulsify two phase fluid.

慢而恒定的转动不会使用两相流体乳化。

Zone is the range of enmironmental temperatures in which an endotherm has only to exert a minimum metabolic effort in order to maintain a constant body temperature.

热中性区是环境的温度范围，在这个温度范围内，内温动物仅使用一个最小的代谢率以维持恒定的体温。

The thermoneutral zone is the range of enmironmental temperatures in which an endotherm has only to exert a minimum metabolic effort in order to maintain a constant body temperature.

热中性区是环境的温度范围，在这个温度范围内，内温动物仅使用一个最小的代谢率以维持恒定的体温。

The further away from the thermoneutral zone that the environmental temperature moves, the more energy the endotherm has to expend to maintain

环境温度离热中性区越远，内温动物维持恒定体温消耗的能量越多。

The further away from the thermoneutral zone that the environmental temperature moves, the more energy the endotherm has to expend to maintain body temperature.

环境温度离热中性区越远，内温动物维持恒定体温消耗的能量越多。

The Church - because it embraces all nations and is destined to endure to the end of time - of its very nature requires a language which is universal, immutable, and non-vernacular.

圣教会——由于她拥抱一切国度民族，并注定要坚持到世界穷尽——本质上要求一种共通的、恒定的、非某国某族的语言。

The model was developed based on the assumptions of constant top boundary concentration and equilibrium linear adsorption.

基于顶部边界污染物浓度恒定及平衡线性吸附假设，建立了该模型。
