single-space

The error-code detecting instrument controlled by single-chip has some distinct advantages, for instance, it is accurate, low power-consuming, space-saving, and its price performance ratio is high.

采用单片机来控制的误码仪，更是集低功耗、高精度、体积小、性价比高等优点于一身的智能性测试仪，并其可靠性得到显著提高。

The analysis and simulation indicate the optical synthetic aperture technology by coherent imaging can improve the resolution dramatically compared with traditional single-aperture telescope. It is valuable for realization of lightweight and modularity of space-based optical remote sensing system.

分析和仿真结果表明：光学综合孔径通过相干成像不但可以突破传统单孔径系统的口径局限获得极高的成像分辨率，而且对于实现空间光学遥感系统轻量化和模块化都具有重要意义。

Under the assumption that the electron beam is single-velocity and one-dimensional, the transmission equation of space charge wave set up in the conical electron beam is derived and the process of noise impedance transformation is obtained.
