The anode structure of CI-LIGBT is optimized by numerical simulation, and it is pointed out that segmented p〓 anode region surrounded by n〓 anode region is the key to improve the ability of current limiting, and the more deeper the n〓 anode junction relative to the p〓 anode junction, the more powerful the ability of current limiting is. The affection of the breakdown voltage BV〓 of the reverse biased p〓n〓 junction and the sample resistance upon the latching current, the latching voltage and the on-state voltage have been studied, and it is indicated that the tradeoff between the on-state voltage and the latching characteristics is the excellentest when BV〓 is 1. 1V so that its on-state voltage can be just only 0.6V higher than conventional LIGBT. It is also found that this device is especially suit to high temperature environment. Based on X. B. Chen's surface voltage sustaining structure using optimized variational lateral doping and Ludikhuize's multiple floating rings structure, high voltage LIGBT and is studied in this paper.

However, must clearly recognize that the current stock is still in the downward trend, the downward trend of the whole without any tendency to reverse, the most obvious short average surface now under pressure, on the 5th line to become difficult to break, along the "line of defense"; BOLL channel fully operational in the downlink channel, and there are no signs bottomed; and major trends TRIX and MACD indicators are in a strong explore the stage; OBV indicators downlink unable to fully demonstrate that the market inside and short-term to maintain the disadvantaged pattern indexes to reverse the trend away from the whole is still too early!

但是，必须清醒地认识到，目前的股价仍然处于下降趋势，但整体下降的趋势没有任何扭转的趋势，最明显地表现在短，平均压力下，五日线成为难以打破，沿防御&线&；波尔渠道充分的下行信道的业务，而且没有迹象见底；及基质的主要趋势和MACD的指标是一个强大的探索阶段，成交量净额指标下行无法充分表明，内部和短期市场，维持弱势格局指数扭转这一趋势远离整体还为时尚早！

At the same time, introduces systematically the history and current situation of displacement reverse analysis, describes the displacement reverse analysis theory of the elastic-plastic problem, and based on the actual project, this paper presents displacement reverse analysis in the application of the tunnel project.

同时，较为系统地介绍了位移反分析方法研究的历史与现状，叙述了弹塑性问题的位移反分析理论，并结合实际工程，研究了位移反分析在隧道工程中的应用。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大，发射区禁带较宽，有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流；在大多数情况下，基极电流以准中性基区复合电流为主，其与集电极电流的比值随集电极电流和温度的变化极小，稳定了电流增益。
