Road vehicles - electromagnetic compatibility test procedure of automotive components - part 6 : qualification of the immunity to narrowband interference according to the current injection procedure 道路车辆.汽车部件的电磁兼容性试验程序.第4部分:根据通用喷射程序窄带抗干扰性的合格鉴定
The advantages of the two methods are combined together in the pseudo - random current injection testing method , which improves the efficiency and correctness of the test , and which is much more operable , thus it is very applicable in built - in - self - testing of analog and mixed signal circuits in system chips 伪随机注入电流测试法结合了两种方法的优点,提高了测试的效率和正确性,实现时简单易行,非常适合于系统芯片中对模拟及混合信号电路的内建自测试。
4 design of hb - led is focused on mqws and top layer . compensatory mqws for led active layers have led to good results follow the analysis in former two chapters . systematic analysis of current injection and light output via external quantum efficiency of hb - led showed mat the optimum of top layer of hb - led is appeared to be between 15 u m and 20 u m , and at least is 5 u m 根据前两章的分析设计出补偿应变多量子阱的有源区结构;然后分析计算了器件的电注入和光输出过程,指出降低顶层的电阻率和增加顶层厚度都可以使注入电流更有效地扩展到上电极外面的区域,增加厚度还可以增加器件的侧面出光。
A new viewpoint to observe the relation of bus voltage , bus current injection and branch current of the network considering branch mutual inductance has been provided in this paper . the process of building the z - matrix of a large - scale power network is set forth in particular in this paper . and the method is employed in the fault computation system successfully 本文为了从算法上提高故障计算的速度,在完全计及支路互感的前提下,利用节点注入电流与支路电流以及支路电流与节点电压的关系,提出了一种能够统一处理互感和无互感线路、快速形成大规模电网节点阻抗矩阵的新方法。
Appling p - n graded heterojunction instead of abrupt one is studied deeply in theory , and the conclusion is that it will enhance the current injection ratio , decrease the built - in voltage , improve the quality of the crystal and it will not affect the confinement to the hole 在理论上提出在hb - led器件的dh结构中使用p - n结的渐变异质结替代现行的p - n突变异质结。分析采用异质结渐变方式将增加hb - led的电流注入比,减小内建电势,改善晶体质量,并且不影响p - n结对空穴的限制。
