This test indicates that using bicortical screws in the first and third hole of the proximal end of the LISS is the best way for treating distal femur fractures AO/33-A3, it can not only reach the best balance and it create the biggest force to resist torsional force, but also decrease the shearing force, torsional force so as to prevent hardware failure.

采用LISS钢板治疗股骨远端33-A3型骨折时，骨折近端螺钉第1、3孔双皮质固定在钢板、螺钉的固定平衡性及对抗扭转拔出方面明显优于其他各试验组，能够有效地降低钢板、螺钉与骨质之间的剪切力和扭转力，从而防止螺钉、钢板早期松动脱落。

Through Hilbert transform, a signal's plane trace can be get. There are two frequencies in the tested signal, so the signal's plane trace may be looked as the track of the out pole's end when two poles rotate around parallel axles. Using the knowledge of motion synthesis in theory mechanics, a formula to describing the change of plane trace's step length and angle for two-frequency be get. So we may prolongate the tested signal's plane trace from the echo's initial arriving moment, and get a certain length of the signal's prolongation.

通过Hilbert变换可得到测试信号的平面迹线，测试信号中只含有两个频率成分，视为双频信号，双频信号的平面迹线相当于两连杆绕平行轴转动时外杆杆端迹线，利用理论力学中运动合成和瞬心知识，推导出双频信号平面迹线步长平方满足余弦线性复合函数，而迹线转角可视为线性变化，据此可对回波到来之前的测试信号平面迹线作延长，得到一定长度的信号延展段，信号延展段与实测段作差可得到一次、二次回波的第一个波峰值。
