To perform CRS stack depends on the determination of three wave attributes,compared with conventional common middle point stack and dip move out stack,CRS stack can focus more energy in the vicinity of the reflector,therefore can obtain a better zero offset section by stacking events with same phase.

共反射面元的旅行时响应由三个波场属性参数确定，相比常规共中心点(commonmiddlepoin ，CMP)叠加和倾角时差校正(dipmoveout，DMO)叠加，CRS叠加算子能够将地下反射点附近一个邻域内的能量进行聚焦并实现同相叠加，因此能得到更好的零炮检距剖面。

Besides this, a tragedy is impossible without action, but there may be one without Character. The tragedies of most of the moderns are characterless--a defect common among poets of all kinds, and with its counterpart in painting in Zeuxis as compared with Polygnotus; for whereas the latter is strong in character, the work of Zeuxis is devoid of it.

点源是指通过排放口进行集中排放的污染源；非点源，是相对于点源而言的污染源，通常意义的非点源是指由于暴雨的动力作用，地表产生径流，各类污染物质随水土迁移，对受纳水体形成的冲击性污染。

Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov. Original mantle-normalized distribution pattern of incompatible elements is one kind of rich -in-strongly incompatible elements type with enrich of K and loss of Sr, P, Ti and trace element association makes a feature of siderophile and chalcophile elements. The tectonomagmatic discriminating shows that mantle -derived granitoids in Southern China belong to orogenic granitoids formed in island arc/marginal sea basin system.

以本洞和西裘岩体为例，论文阐明了华南幔源型花岗岩稀土和微量元素地球化学特征，表现为稀土总量较低，轻重稀土元素分馏明显，负铕异常和∑LREE/∑HREE、〓、〓比值较高，与维氏酸性岩平均值相比华南幔源型花岗岩过渡族元素含量较高而大离子亲石元素和非活动性元素含量较低，不相容元素原始地幔标准化分配型式属强不相容元素富集型并呈K富集而Sr、P、Ti亏损的特点，微量元素组合以亲铁和亲铜元素为特征，构造岩浆判别显示华南幔源型花岗岩属造山花岗岩，其形成构造环境为岛弧/边缘海盆系统。
