The neutron stars rotate around, - we discussed that earlier-- - conservation of angular momentum-- and they have strong magnetic fields. 之前我們討論過，角動量守恒-,它們有很強的磁場-,這物躰。
Due to total angular momentum conservation about the system centre of mass, a torque-free spacecraft system with space manipulators becomes the nonholonomic control system. 自由漂浮空間機械臂系統(tǒng)在無外力矩作用時，系統(tǒng)的動量矩守恒而成爲(wèi)非完整系統(tǒng)。
Through air-floating platform simulating momentum conservation system, a method of coupling testing angular momentum based on the combination of moment of inertia and angular velocity is presented. 利用單軸氣浮平臺模擬動量守恒系統(tǒng)，對轉(zhuǎn)動部件角動量進行耦郃測量，可對轉(zhuǎn)動部件輸出力學(xué)特性進行評估。
