In previous studies, only spherulitic structures of PVDF membranes prepared by PVDF/single diluent systems via solid-liquid phase separation were obtained. The PVDF membranes with spherulitic structures always present poor mechanical properties, dense skin layers and wide pore size distribution.

在以往的研究中，PVDF微孔膜大多数选用的是单一稀释剂，通过发生固—液相分离制备的，所得到的膜结构都是球晶状结构，具备这种结构的膜往往存在膜的力学强度差、皮层致密和孔径分布宽等缺点。

The results show that the samples mainly consist of amorphous resinite and humus, where the microtopography of the organic constituent is irregular squamose groups.

This paper makes a three-dimensional model for QCM and analyzes directly the coupled phenomenon of the structural and electric fields of QCM with finite element analysis software ANSYS10.0. Through analyzing the convergence of the resonant frequency of QCM, the correctness of the finite element analysis is proved. The influence of different sizes of electrode on vibration of QCM and an optimal size of electrode is discovered, namely thickness of 100 nm and radius of 3 mm. The design of mesa on crystal plate is provided to solve the problem that the energy trapping is not good enough. This design proves valid based on finite element calculation and an optimal size of the mesa is given, namely height of 9.8 μm.
