晶闸管可分为标准型(即慢相控制型)和快速转换电压反馈变极型。

Thyristors can be classified as standard, or slow phase-control-type and fast-switching, voltage-fed inverter-type.

DCMU作用后叶片DF衰减动力学曲线表明在快相部分有明显上升趋势，而慢相部分出现下降。

The fast phase of DF decay curve of leaves obviously rise after DCMU treatment, while the relative slow phase declined.

针对采用调频连续波(FMCW)体制的天波超视距雷达的应用场合，提出了一种电离层扰动(慢相径变化)补偿改进算法。

This paper presents an improved arithmetic for extracting and compensating the phase-path variations caused by the ionospheric disturbance in a HF sky-wave OTH radar with FMCW waveform.
