Calculation of the overlap factor and correction of near-field signal of the off-axis lidar based on the Gaussian mode of laser beam 基于激光器输出模式的离轴激光雷达重叠因子计算及近场信号校正
An appropriate switching frequency is essential to ensure the smooth transition of synchronous machine from low speed operation to high speed operation, which means that there should be an adequate frequency overlap between the upper limit of pulse mode and the lower limit of synchronous mode. 要保证同步电机由低转速运行平稳过渡到高转速运行,必须使脉冲方式下的频率上限与同步方式下的频率下限之间重叠部分有足够的裕度,即选择合适的切换频率。
In this work, the field distribution of electrodes is analysed to determine the maximum overlap integral affected by the parameters of electrode width, interelectrode gap and optical mode size etc. 本文利用集成电光调制器电极电场的分布规律,研究了各种结构中影响电光重叠因子的诸参量之间的关系;
The reason is the range of overlap frequency between hybrid mode G1 and G2 will increase when density of plasma-background increases. 这是因为随着增加,混合模G1和G2重叠的频率范围逐渐加大,稳定工作区变窄。
For the coupling between the laser diode and the tapered single-mode fiber, the overlap integral is used to compute the coupling efficiency on the basis that the laser diode outputting mode field and the fiber eigenmode field is approximated to basic-mode Gauss field. 首先通过对半导体激光器输出模式场和光纤本征模式场的高斯基模近似,利用交叠积分计算了锥形单模光纤与激光器的耦合效率问题;
For silica planar waveguide AO Bragg device, the influences of acoustic frequency, waveguide mode and thickness on overlap integral and the impacts of waveguide mode, acoustic power and acoustic aperture on diffraction efficiency are discussed. 对Si02平板波导型声光Bragg器件讨论了声频率与光波导模式及厚度对重叠积分的影响及波导模式、声功率和声孔径对衍射效率的影响。
Serial port can have two kinds of operation mode: synchronous operation mode and overlap operation mode ( also known as asynchronous operation mode). 串口的操作可以有两种操作方式:同步操作方式和重叠操作方式(又称为异步操作方式)。
For the problem of concurrence between disgorgement and the right of claiming for damages, our legislation should adopted overlap mode. 而对于公司归入权和损害赔偿请求权的竞合问题,我国立法可采重叠模式。
