空穴

At these extremely high frequencies, internal quantum-mechanical oscillations of the excitons themselves were excited.

在这种超高频的情况下，电子空穴的内部量子震荡会被激发出来。

The relationship of"fisheyes"production with voids coalescence was also studied.

最后分析了塑变过程中&鱼眼&的产生与空穴聚合间的关系。

This phenomenon is in accordance with the results of electrical conductivity measurement, t〓 decreases with temperature, the reason may arise from the electrode polarization or the gas leakage through the pellet 〓.

根据实验测得的电导率随氧分压的的指数关系，本文提出了一种新的模型对〓的i～E极化曲线进行拟合后分别得到了电子和电子空穴电导的数值。

A wheat hill drop planter used for perpendicularly inserting film mulching field was developed and its major shortcomings existed in the roller type planter were overcome.

引言滚轮式小麦覆膜穴播机存在的突出问题是种穴与膜孔错位率高，穴粒数均匀度差，易于造成空穴，成穴器撕膜、挑膜严重，种孔覆土不良。

Stacked PIN diodes in parallel and series operate at a hold-off voltage of 8.0 kV,and the dV/dt is promoted from 2.4 kV/ns to 3.2 kV/ns. Delayed breakdown device ; PIN diode ; Delayed breakdown

因此在输入脉冲 dV/dt很快的情况下，二极管会产生很高的过压，这时空间电荷区的电场强度远远大于雪崩击穿的临界场强，电子和空穴的电离率非常高，导致二极管在很短的时间内击穿，这个现象被

The improvement in luminescence intensity of step-like InGaN QW was found to be 1.54 times higher than that of the convention one.

与传统的InGaN构型量子阱结构相比，使用台阶型InGaN构型的量子阱结构，活性区载流子浓度特别是空穴浓度得到明显的改善，输出功率和内量子效率分别提高了52.5%和52.6%。

Now,more and more experiments have indicated that the primary excitations in luminescentpolymers are the interchain excitons,so it is not sufficient to only study the single chainof the polymer and the interchain coupling must be considered.

对于实验中更为可能的反平行情形，当激子中的电子和空穴不在一条链上时倾向于分开一段距离，这与实验工作者提出的&空间非直接激子&的概念相吻合。

Chapter five: The magnetocaloric effect in layered perovskite manganese oxide 〓 was studied.

第四章 保持空穴浓度x=0.3不变，研究了Ba〓掺杂对晶体结构和磁输运行为的影响。

In this paper, we use optimal hole-doping manganites La0.3Ca0.7MnO3 as the mother material of the composites compounding with ZnO.

在本文中以择优空穴掺杂的钙钛矿稀土锰氧化物La0.3Ca0.7MnO3 为复合材料的母体，将其与ZnO复合。

The existence of such centers. is attributed to defects in crystals resulting from isomorphism between cations of different valences.

阳离子不等价类质同象造成的晶体缺陷，是使其具有电子-空穴心的内在因素。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
