A structure of space-time diversity virtual double-route weighting interference mitigating is proposed, and the corresponding practical algorithm is derived in detail using block matrix inversion formula and matrix inversion theory for mitigating interference signals from both other cells and other users of local cell in the DS-CDMA up-link communication case. Performances of such algorithm are thoroughly analyzed through simulation and analytical results. The up-link and down-link channel characters and their relationship of DS-CDMA communication system are thoroughly analyzed, and the relationship of space-time diversity weighting matrix between time division duplexing and frequency division duplexing these two different transmission ways is derived.

在气垫导轨上做碰撞实验，最大限度地减少了摩擦阻力的影响，但在实际的实验过程中，仍发现滑块的初速度不同时，粘滞性摩擦阻力对测量结果有不同程度的影响，为此在气垫导轨上增加了电子发射装置，较好地控制滑块的初速度和测量滑块的加速度，从而减小粘滞性摩擦阻力对测量结果的影响。

V2：撒但这样对他最亲近的伙伴说着，把他的头抬出火焰的波浪上面，两只眼睛，发射着炯炯的光芒，身体的其他部分平伏在火的洪流上，又长又大的肢体，平浮几十丈，体积之大，正象神话中的怪物，象那跟育芙作战的巨人泰坦，地母之子，或象百手巨人布赖利奥斯，或是古代那把守塔苏斯岩洞的百头神台芬，或者象那海兽列未坦，就是上帝所创造的一切能在大海洪波里游泳的生物中最巨大的怪物：据舟子们说，他有时在汹涌的挪威海面上打瞌睡，常有小舟夜航而遇险的时候，以为他是个岛屿，抛锚扎在他的鳞皮上，碇泊在他身旁的背风处，在黑夜的笼罩中等待姗姗来迟的黎明。大魔王就是这样横陈巨体，被锁在炎炎的火湖上面，既不能起立，也不能昂起头来，但由于那统治万汇的天神的意志和他的洪量，让他自由地得逞阴谋，他心想危害别人，却终于加重自己的罪行，刑上加刑，让他懊恼地看见自己一切的恶意怎样在他所引诱的人身上带来无穷的善意、恩惠和怜悯，而在他自己身上却招来了三倍的慌乱、惩罚和报复。

A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.

该振荡器在阴极电子发射起点加圆环，控制此处电子束的发射密度，来减少电子能量的损耗，改善束－波互作用；逐渐加大慢波结构的后两个叶片的内半径，增大微波群速度，便于谐振腔中的能量输出，提高微波输出效率；采用两个扼流片有效地阻止了微波功率向二极管区泄漏，相应减小了器件的尺寸。

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。
