This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.

以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄，使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高，从而易导致CA膜形成双连续结构；温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近，均相区减小；ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制，而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。

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。
