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。

Written record can not be replaced by the video camera, as they advantageous to and more appropriate than video records in providing subjective experiences, feelings or emotions. Written records are more competent for in-depth and comprehensive contents. Moreover, long-span temporal and spatial events can be easily recorded documentarily.

文字记录的作用是不可被数码摄像机所取代的，因为文字记录可以记录数码相机所不能记录的人的主观感受，文字记录可以表达数码相机所不能表达的深刻，全面的内容，而且可以记录时间，空间跨度大的内容。

The study shows that the advantageous sandstones in the area have the following distribution characteristics: in the environment of growth faults, sandstones are mainly distributed in the downthrown block of a boundary fault; in a lowstand systems tract, sandstones are mainly distributed in lowstand wedges, slope fans, basin-floor fans, fan deltas, deltas and submarine canyons; in a transgressive systems tract, sandstones are mainly distributed in sandbars and sand-beaches; and in a highstand systems tract, sandstones are mainly distributed in deltas, fan deltas and submarine fans.

并指出有利砂体的分布特征：低水位体系域，砂体主要分布在低水位楔、斜坡扇和盆底扇；高水位体系域，主要分布在三角洲、扇三角洲、海底扇和峡谷水道。研究表明，以层序地层学理论为指导，划分层序和体系域，进而对有利砂体进行预测，对该地区油气勘探有重要指导意义。
