Dynamical characteristics of the gyroscope during spin-up and erection procedure, and the influence of the stray magnetic field on gyro's drift and speed attenuation are investigated.
讨论了陀螺在驱动、定向过程中的动力学特性，以及杂散磁场对陀螺漂移和转速衰减的影响。

Philae was nudged gently away from Rosetta at a speed of about 80 centimetres a second, and left to drift towards the comet under the influence of that object's feeble gravity.
“菲莱”以每秒80厘米的速度被推离开罗塞塔，在彗星很小的引力作用下漂向彗星。

In case of the noise statistic being unknown or variable, adaptive Kalman filter is used to get driftspeed of each axle at each test position, and then drift parameter is calculated.
