- 它没有假设地球是一个完整的球面，而是考虑了地球的极轴扁平率和赤道鼓起率，这样就给出了两个坐标间更精确的距离。
Instead of assuming the Earth to be a perfect sphere, this function takes into account the actual polar flattening of the earth and the equatorial bulge, which gives a much more accurate computation between the given coordinates. - 在某一平面上，一定角宽范围内所包含的光强极轴曲线上的矢径长度均大于其最大值的某一特定比例，这种情况定义为光束的发散。
The angular extent in a specified plane which contains all the radius vectors of the polar curve of luminous intensity having lengths greater than a specified fraction of the maximum. - 研究了三相四对极轴向磁场微电机的步进控制逻辑，建立了鉴码系统的动力学模型，分析了系统的模态和不同摩擦参数下的动力学响应。
The stepping control logic of three phase four pair poles micromotor was studied, the dynamic model of code discrimination system was set up, and the mode and the displacement response of gears shaft assembly with different friction torque were computed.
