Control strategy : vector control and sinusoid control .

控制策略：向量控制与弦波控制。

Since the frequencies of two sinusoid signals are very close , it is difficult to separate them with filtering .

由於此波讯号之频率太靠近，以致於很难使用滤波器分别滤出其中之一。

The low expression of fibronectin and laminin plays an important role in the pathogenesis of the abnormal sinusoid wall in och .

纤维连接蛋白和层粘连蛋白低表达在血窦壁异常结构形成中有重要作用。
