Simplier and more efficient ion extraction methods for atomic vapor laser isotope separation AVLIS were evaluated using a 2-D electron-equilibrium model to compute and compare three electrostatic methods the parallel electrode method, the Π type electrode method, and the improved M type electrode method.

为探索用于原子蒸气激光同位素分离AVLIS的简单有效的离子引出方法，用二维流体理论电子平衡模型计算比较了3种静电场方法平行板电场法，Π型电极法，改进M型电极法计算发现，二维流体理论电子平衡模型并不能很好地描述Π型电极法对另外两种静电场方法，计算了不同外加电压、不同的初始原子密度和不同的目标同位素丰度等条件下的离子引出情况从计算结果可以看出，改进M型电极法不论是从离子引出时间还是从碰撞损失率，都要比平行板电极法好得多当外加电压较高或初始原子密度较高时，这种好处就更加明显因此，改进M型电极法是一种可供实际采用的比较好的静电场方法

Which points to a wonderful paradox: the very fact that we now revere Tocqueville to the point of writing novels about him is proof that one of his guiding ideas about the evils of democracy was bunkum, if magnificent bunkum.

这段对白引出了一个非常巧妙的矛盾：我们尊敬托克维尔，并为此写了一部有关他的小说，可这一切都证实他有关民主罪恶的指导思想是胡扯，尽管是极华丽的胡扯。

In this dissertation, InGaAs/InGaAsP/InP MQW microdisk laser and its characterization were presented. Some conclusions are as following: the characteristics of lasing threshold was discussed by using rate equation. The dependent relations between threshold and cavity volume, spontaneous emission coupling efficiency β were investigated. The whispering gallery mode and spontaneous emission in a microdisk geometry were then studied. Almost all spontaneous emission was coupled into the lowest order TE mode when the normalized thickness of photonics well was between 0.15 and 0.5. The design principle and device process of InGaAs/InGaAsP/InP MQW microdisk laser were presented. The microdisk lasers with the diameter of 8μm, 4. 5μm and 2μm were succesfully fabricated by using etching techniques. The pulse lasing thresholds for the microdisk with the diameter of 8μm and 4. 5μm were 170μW and 15μW, a record results compared with the published in the literature. The cw lasing threshold for a 2-μm-diameter microdisk was only a few μW. We haven't found similar report up to now. To solve the problem of directional output in a microdisk laser, the power coupling efficiency in a double disk geometry was investigated with the theory of waveguide mode couple. A new structure of electrically pumped microdisk laser with output waveguide was designed, making a foundation for the practical use of microdisk laser.

The practical example indicates that the method used in complex countercurrent multi-effect evaporation system is fast and accurate.The vapor consumption of three-effect evaporation with condensed water flash is decreased by about 10% for condensation of NaOH solution. Loss of heat energy increases for preheating of feed with fresh vapor or extra vapor withdrawal.
