The mechanism of this spectral shift lies in the electrical field ionization of excitons.

这种光谱的移动机制依赖于激子的场致离化，这种作用起源于能带模型的应用而非分子激子理论。

According to the theory of excitions generation and diffusion, the relationship between spectrum intensity and the thickness of every layer, the excitons diffusion length is discussed. The result of the theory analysis is in good agreement with the experiments.

根据激子产生和扩散理论，讨论了器件性能对于各发光层的厚度及激子扩散长度的依赖关系，拟合结果与实验结果吻合。

The computational results show that there exists a rupture shock wave and a secondary explosion wave in the external flow field during venting.

计算结果显示在外流场中出现了破膜激波和第二道激波。

The flow-field around a hemisphere and a flat-nosed cylinder in the shock tube is simulated numerically by using non-equilibrium Navier-Stokes equations with an air chemical model of 5 species 17 reactions, and the catalytic rate constant of surface materials such as Pt, SIC:, Ni and a flight vehicle materials is determined by using the heat transfer rate of testing in the shock tube and the distribution of heat transfer rate along with the catalytic rate constants.

用5组分17个化学反应Durm-Kang空气化学模型和轴对称热化学非平衡Navier-Stokes方程，对激波管中球头和平头圆柱模型绕流流场进行了数值模拟，给出了驻点热流随催化速率常数变化的分布，并根据激波管实验测量的热流值确定了表面材料Pt、SiO2、Ni和某种飞船材料的催化速率常数，建立了数值分析高焓流动边界层催化特性的软件。

These versatile devices can be used in various power topologies, such as flyback, forward and half bridge resonant LLC.

The theory of enthalpy flow and phase shift is applied to explain gas wave refrigeration.

但是，激波理论描述气波振荡管内流动时忽略了封闭阶段，而且不能很好解释管外强化换热、等熵效率波动等实验现象，说明激波理论也存在着一些缺陷。

Most gasifiers with quenching process have the problem of carrying water in the quenching chamber, which is more obvious under high load conditions constraining the increase of the gasifier load.

采用激冷流程工艺的气化炉，大都存在着激冷室带水的共性问题，且在高负荷生产状况下尤为明显，直接制约了气化炉负荷的提高。
