After this research work, we know that: HMCM-22 is a better catalyst of selecting naphthalene alkylation; Surface modification of zeolite Y is effective, but the effect of zeolite 3 is not evident and surface modification doesn"t suits mordenite; Surface modification doesn"t affect the frameworks and inner environments of zeolites, but only reduces diameter of orifice and overlays surface acidities; t-butanol is not suitable for alkylating agent of the reaction using modified zeolites as catalyst; Solvents with smaller molecular size are advantageous for naphthalene alkylation reaction using modified zeolites as catalyst, such as cyclohexane is better than decalin.

通过本论文的研究，我们知道：HMCM-22是萘择形烷基化反应较好的沸石之一；Y沸石的外表面改性效果较好，β沸石则效果不明显，而丝光沸石则不适于外表面改性；外表面改性不改变沸石的骨架结构和孔道内部环境，仅减小孔口直径和覆盖外表面酸性位；叔丁醇不适于作外表面改性沸石催化的反应的烷基化试剂，其反应活性很低，且选择性无明显提升；分子较小的溶剂更适于外表面改性沸石催化的反应，环己烷就明显好于十氢萘。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

One is Bardina vorticity modification, and the other is Richardson number modification. Prediction results show that Bardina method has a superior capacity to Richardson number modification. Since DSM model has improved predictive results of the reversed velocity and tangential velocity, it is a potential method to predict strong swirling nonisotropic turbulent flow in stead of the longer convergence time.

本文采用了基于旋转体系使湍流脉动加强和削弱两种作用的修正方法对k-ε双方程的湍流耗散率方程进行修正，计算结果表明，从旋转体系可使湍流能量加强出发的Bardina涡量修正方法，预报回流区范围缩小，更加接近于试验值，其计算结果优于使湍流脉动削弱的Richardson修正。

With titanite as the surface modification agent of sericite, the effects of the dosage of modification agent, massic ratio of midium/sericite, density of slurry, grinding time, temperature and pH value on the surface modification were analyzed.

In the second chapter, elementary theories and ideas of one step forming inverse approach were described and warped modification method, implemented by Cook, was introduced into one step forming simulation and based on idea of surface spreading; new quadrilateral element modification arithmetic was put forward. By spreading warped quadrilateral onto plane in local coordinate system, a plane quadrilateral element whose shape and area were equal to original warped quadrilateral element was gotten and internal force vectors of four nodes and stiffness matrix of elements were improved to increase precision of simulations on this plane element.

第二章从一步成形逆有限元法的基本理论和思想出发，将Cook基于弹性理论的四边形单元的翘曲修正算法引入基于塑性的一步成形，并且基于曲面展开的思想，本文提出一种新的四节点单元翘曲修正方案，通过把翘曲的单元展开的方法在局部参考系中得到一个与实际翘曲单元的形状与面积非常接近的平面单元，在该平面单元中进行单元刚度及内力向量的计算，进一步改善模拟结果的精度。
