The modified eccentric circular centrode has been obtained by reducing the polar Angle of polar equation of eccentric circular centrode by integral multiple.
通过使偏心圆齿轮节曲线的极坐标方程的极角按整倍数缩小的方法获得了变形偏心圆齿轮节曲线的极坐标方程。
Radius and orbital velocities can be directly expressed as functions of time or polar angle, which is helpful for designing flight mission and motion trajectory.
这种方法可直接获得向径、轨道速度等参数随时间或极角(绕地心的转动角)的变化,便于分析轨道转移与逃逸运动,有助于飞行使命与运动轨迹的设计。
It is the season for viewing Polar Mesospheric Clouds, and with our high beta-angle we were able to capture this thin layer of noctilucent clouds at sunset (6-25-2010).
到了观看极地中气层云的时候,在太空中使用高β角度,我们能捕捉到日落时刻这层薄薄的夜光云。
If it's in polar form I passed in a radius and angle and I'll compute what the x- and y- value is.
以及半径和角度,但是现在是这样的,不管我是以哪种形式。
