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。

Mehtods Thirty male SpragueDawley rats were randomly divided into acute stress,chronic stress and control group(each n=10),acute and chronic stress models were made with forced swimming and empty bottle stimulation separately,and frequency of getting into central grille, detention time , outer grille numbers,modifying numbers and dejecture grain number were observed with openfield experimental box;expressions of neuropeptide Y and adenylcyclase in prefrontal lobe cortex, hippocampus CA3,striatum of the groups were observed using the immunohistochemistry method and correlation analyses conducted.
