Effect of qianggu kangwei formula on osteoblasts cultured in vitro under simulated weightlessness 強(qiáng)骨抗萎方對(duì)模擬失重條件下體外培養(yǎng)成骨細(xì)胞的影響
The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance . performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center , and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground . so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis 氣浮臺(tái)能夠模擬衛(wèi)星在軌失重條件下的姿態(tài)運(yùn)動(dòng),是衛(wèi)星姿態(tài)控制系統(tǒng)物理仿真的核心部件,其轉(zhuǎn)動(dòng)慣量和質(zhì)心偏移引起的重力干擾力矩等決定了基于氣浮臺(tái)的衛(wèi)星姿態(tài)物理仿真系統(tǒng)的性能,并且利用氣浮臺(tái)可以實(shí)現(xiàn)衛(wèi)星質(zhì)量特性在線辨識(shí)算法的地面物理仿真驗(yàn)證,因此本文對(duì)衛(wèi)星和氣浮臺(tái)的質(zhì)量特性及干擾力矩在線辨識(shí)問(wèn)題進(jìn)行深入研究。
