变频调速
This thesis focuses on the difficulties of motor harmonics and heating in the frequency conversion timing process.
主要研究了变频调速过程中电机谐波和发热的难点问题。
频率变换
The frequency conversion technique applied universally in the field of solid-state laser is studied: the second harmonic wave theory on the base of the coupled wave theory. The effect of phase-matching upon conversion efficiency is mainly analyzed.
本章还分析了固体激光领域普遍采用的频率变换技术：建立在耦合波理论上的二次谐波理论，重点分析了相位匹配对转换效率的影响。
变频技术
With the chip microprocessor and frequency convertor,introducing fuzzy control to frequency conversion,then the ventilator is controlled,and the CO concentration can keep in a allowable range.
通过单片机和变频器的结合,采用模糊控制下的变频技术控制通风机的运行,使停车场内CO浓度保持在允许范围之内。
