Based on the principle of period transit method, semi-period transit method of collimation is proposed to improve the north-seeking speed and the automatic degree. 由陀螺仪寻北中天法的基本原理出发,提出了一种固定照准部的初寻北半周期中天法。
Since semi-period of 1980s, Singapore begin to pay close attention to international education service which be regarded as knowledge service industry. 1980年代中期以来,新加坡开始关注作为知识服务产业的国际教育服务。
Application Research of Semi-Period Transit Method on Coarse North-Seeking 半周期中天法在初寻北中的应用研究
Simulation results show that both semi-period algorithm and three points algorithm possess the feature of simple implementation and good real-time performance, so it is suitable to the practical application of dynamic voltage restorer. 仿真结果表明,半周期算法和三点算法都具有实现简单、实时性好的特点,适用于动态电压恢复器的实际应用。
