A diffractive_refractive hybrid singlet is used to replace a binary optical phase lens for an imaging spectrometer. 提出利用折衍混合透镜代替单一的二元光学透镜来实现色散和成像用于超光谱成像仪,论述了此透镜系统的设计方法,给出了理论设计公式。
According to the variation characteristic of starting torque and power of screw pump well, binary power motor was introduced to replace Y-series motor. Compared with Y-series motor, binary power motor could save more than 10 % electrical power. 对此,在理论分析和现场测试的基础上,根据螺杆泵井启动扭矩和功率的变化特点,引进了双功率电动机,与Y系列电机相比,节电可达10%以上。
