Forming part of the paragraph L / D ≥ 1 and for forming slip paragraph 1 / 2 of the gas-assisted die, as the entrance to the storage of elastic strain energy in the gas-assisted paragraph has been fully released from the mold after the swollen out of the mouth than with the Import model geometry has nothing to do

对于成型段部位L/D≥1且滑移段为成型段1/2的气辅口模，由于入口储存的弹性应变能在气辅段已经完全释放，离模后挤出胀大比与口模入口几何结构无关。

The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

结果表明，TiO2溶胶与苯丙乳液混合后，陈化时间的延长有利于TiO2胶粒通过静电、氢键作用在苯丙乳液粒子表面形成吸附层，从而改变涂膜液的成膜性，形成较为密集、且均匀分布的岛状多孔结构，在此基础上经两次涂膜，即可获得具有致密孔洞的TiO2多孔薄膜。

At present, although finite element methods is a kind of effective measures in analyzing metal plastically forming problems with friction, dynamic friction in the process of metal forming is substituted with static friction and constant frictional force as one of independent constraint conditions is transposed to equivalent node-load or FEM unit is divided into contact unit and inner unit in numerous studys and applications, so that it result in relative bad accuracy and awkward operation. These defects mostly attribute to the fact that FEM bases on the variational equality principles, however frictional constraint will actually result in variational inequality energy functional.

目前，应用于分析金属塑性成形的有限元法是一种有效的处理摩擦效应的定量计算方法，但是许多应用和研究是用常摩擦来代替金属塑性成形过程中的动态摩擦；把常摩擦力作为单独的约束条件移置到等效结点载荷上或把有限元单元划分成接触单元和内单元，这些将导致解的精度相对不高及实际操作不方便等一系列问题，产生这些不足的重要原因之一在于它的理论基础是变分等式原理。
