查询词典 bipolar

The electro-acupuncture is applied with sustained bipolar electric-pulses with 3-4 mA of 60 Hz for"Xinshu"and"Pishu"points,and 20 Hz for"Zusanli"and"Neiguan"points.

电针诱导15分钟后，反应持续期和心率的变化率分别减少至3.90±1.17秒和5.87±1.97%(p.01)。电针的这种抑制作用在取针后30分钟仍未消失。

RESULTS: After 24 hours of preinduction, cells changed from spindle to polygonal or irregular, with many short rod-shape processes and 2-3 nucleoli. Whirlpool shape growth disappeared, and was disordered. After 1-3 hours of induction, cells gradually became round, with significant cell contraction, strong refraction, bipolar or pluripolar processes connected each other into a net. After 5 hours of induction, grades one and two branches were detected.

结果：预诱导24 h，胞体由原来的长梭形变成多角形或不规则形，伸出多个短棒状突起，可见2~3个核仁，细胞间漩涡状生长趋势消失，排列无规律；诱导1~3 h，细胞逐渐变圆，胞质收缩明显，折光性增强，双级或多极的突起互相连接呈网状；诱导5 h，突起出现一、二级分支。

There are two parts in this thesis. Part I focuses on the transient effect in InGaP/GaAs hetero-junction bipolar transistors. Part II focuses on the P memory effect and buffer-layer-quality determination using C-V measurement in AlGaAs/GaAs pseudomorphic high-electron-mobility transistors. The characterization of hydrogen passivation for InGaP HBTs grown on semi-insulating GaAs substrates is studied. The transient effect caused by hydrogen passivation results the current gain ?

本论文分两部分，第一部份讨论在磷化铟镓的异质接面双载子电晶体中，由於氢的包覆效应产生的特性之研究，由於氢在此种元件中所造成的载子包覆现象是引起电流增益增加的暂态现象的主要原因，本论文提出一个计算氢包覆比例的模型，并与SIMS量测的结果相比对，经过几次热回火处理，此种暂态效应可以被消除。
