The microwave active multiplier has advantages of high multiplying efficiency, high stability, and multiplying gain are all over the kind reported at home and abroad, which achieves the aim and meaning of the research of microwave multiplying technology. 研制出的微波有源倍频器倍频效率高,工作稳定,变频增益优于国内外报道的微波有源倍频器,达到了微波倍频技术研究的目的和意义。
We analysis the secondary electron multiplier for micro-channel plate in the first, and then analyzed and calculated the gain of Micro-channel plate. 然后对微通道板的电子倍增特性进行研究分析,通过研究微通道板电子的倍增过程,分析了MCP二次电子发射系数及MCP增益的特性。
Adaptive adjustment of Lagrangian multiplier is brought to make the infeasible solution to approach a feasible one. After the gain of feasible solution, aggregative projection subgradient with the usage of historical information is applied for updating the multipliers. 采用自适应性次梯度法直接修正拉格朗日乘子从而获得可行解,可行解获得以后,运用集结投影次梯度法,对历史信息加以利用,两种策略相互交替。
