For the above phenomenon , a kind of tank motion simulation washout filter algorithm was put forward , and a platform tilt - coordinate maneuver was used to simulate the low frequency motion cueing and high - pass filter method was used to attain the high frequency motion cueing 针对上述现象，提出了一种坦克运动模拟洗出滤波算法，采用平台倾斜策略来模拟运动低频动感，采用高通滤波方法来获得高频运动动感。
Several fabrication methods , including nonwoven meshes / fiber bonding , solvent casting / particulate leaching , phase seperation / freeze drying , gas foaming and three - dimensional printing , which are used to prepare tissue engineered porous scaffolds from natural or synthetic biodegradable materials , are reviewed 摘要综述了以天然或合成生物降解材料为原料的组织工程多孔支架的几种制备方法，包括无纺织物纤维粘结法、溶液浇铸粒子洗出法、相分离冻干法、气体成孔法和三维“印刷”等方法。
