The five-mirror reflector is an integration element cemented by five small reflectors with different angles.
五折镜是由五个平面反射镜按一定角度胶合而成的集成化小型光学组件。
It is a real challenge to the optical manufacturing and cementing technology for this integration element.
这对光学加工和胶合技术提出了严峻的挑战。
Because in U-I model flux observation pure integration element is adopted, it brings about two problems of DC drift error and initial integration error.
考虑到U - I模型磁链观测器含有纯积分电路，会带来两个问题：一是直流漂移误差，二是积分初值误差。
