random velocity

Numerical simulations show that the spacecraft with the symplectic guidance algorithm can follow the reference orbit precisely under the deterministic velocity errors or the random velocity errors, and obtain the satisfying terminal control accuracy.

结果表明：无论确定性速度误差还是随机速度误差，实时制导保辛算法能够保证航天器很好地跟踪标称参考轨道并达到满意的终端控制精度。

We established the stochastic model of threshold friction velocity, and derived an analytical expression of the threshold friction velocity with random variables ( the eccentricity, the eccentricity angle, support angle and contact angle).

建立了临界启动风速的随机模型，推导出含有随机变量（偏心距、偏心角、支持角以及接触角）的临界启动风速的解析表达式。
