It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

The data capture mainly gathers the data from the network. Protocol analysis can analyse every segment of the data packet according to protocol standard. Data recover can recover all the data of the application layer of the TCP connection. IP spoofing can construct all kinds of packets and realize the network attack. Real-time interruption can interrupt the TCP connection of Both sides of communication as the third party. Fire wall can realize network access control. Then the system can protect the network information safety from many aspects.

数据捕获主要完成从网络采集数据的功能；分析还原包括协议分析和数据还原两部分内容，协议分析可以对捕获到的数据包按照网络协议规范分别进行各协议字段分析，数据还原功能可以将每条TCP连接中传输的所有应用数据进行重新组合，还原出原来数据的内容；IP欺骗指构造各种功能的数据包，实现网络攻击；实时阻断指第三方实时阻断通信双方的TCP连接，禁止他们进行数据通信；防火墙主要实现网络访问控制，保护内部子网的功能。

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.

本文采用有限元素分析软体ANSYS进行求解，在有限元素分析的模拟上，外壳与环肋均可用壳元素建立一实体模型来分析，但是在模型的建立上过於复杂，在解析上也需要更多的时间来计算，因此本文采用有效幅度的观念，考虑环肋与壳板间之组合惯性矩，将环肋部分取梁元素来模拟，如此一来可简化建立模型的困难度，且大大的缩短分析的时间。
