The article researched new type thyristor trigger that adapts the frequency of input power automatically, then analyzed the designing ways and process of frequency-tracked trigger in detail, yet validated capability of trigger through experiment and actual appliance in project, we also build up the fault-diagnosed and disposal cell of hypogyny machine with SIMATIC S7-200 PLC, besides, programmed and debugged to realize various monitor and diagnose; more, smart design make protection function more perfect and action more sensitive, so it can realize perfect swift and reliable protection under fault condition.

本文重点研究了以频压变换技术为核心的新型频率跟踪触发器，详细分析了频率跟踪触发器的设计思路和设计过程，实现了在同一移相控制电压下，当同步电压频率大范围变化时触发器输出触发脉冲的电角度保持不变的目的，满足了项目对同步电压频率变化时晶闸管准确触发的要求；并通过实验和工程实际应用验证了触发器的性能。设计了基于SIMATIC S7-200 PLC软硬件的故障诊断系统并调试了各项监控、诊断功能；实现故障条件下准确、迅速及可靠的保护。

The structures and stabilities of the ground-states for Cu13-nAgn clusters have been studied by Gupta model potential based on tight binding second moment approximation in combination with a genetic algorithm. It is found that the lowest energy structures of the pure clusters (n=0,13) are perfect icosahedron, and the structures for the bimetallic clusters (n=1～10) have stable structure which are slightly deformed with respect to the perfect icosahedron, The Cu atom prefers to occupy the center of the clusters with higher coordination numbers.

在混合团簇基态结构优化的遗传算法方案中增加了交换算子，结合Gupta紧束缚模型势研究了Cu13-nAgn团簇的最低能量结构，选择合适的交换和杂交概率，可有效地提高优化效率，优化结果表明，Cu13和Ag13是全对称的二十面体，n=1～10的混合团簇能形成稳定结构，其构型是在二十面体基础上发生畸变，Cu原子趋于处在团簇中心，随着Ag原子数目的增加，原子间的平均距离单调增加，团簇的结合能单调减小，Cu2Ag12和CuAg12只存在亚稳结构。
