The effect of Gauss beam waist and imaging lens F, signal light axis offset, length to wide ratio of rectangular detector and signal light axis tilt to heterodyne efficiency have been analyzed and discussed. 分别讨论了高斯光束束腰和成像物镜F数、信号光光轴偏移量、矩形探测器长宽比(WR)及信号光光轴倾斜角度对外差效率的影响。
Super mild hybrid electric vehicle ( HEV ) takes continuously variable transmission ( CVT ) with reflux power as transmission system. Taking advantage of its wide ratio range, super mild HEV possesses only motor mode, however, mild hybrid electric vehicle has not this mode. 超轻度混合动力汽车的传动系统是以回流式无级变速器作为传动装置的新型车辆传动方式,利用其传动比变化范围大的特点,可以实现轻度混合动力汽车所不具有的纯电动工况的功能。
