The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

To declare what we can do with a set, we start a header file Set.h:#ifndef SET_H #define SET_H extern const void * Set; void * add (void * set, const void * element); void * find (const void * set, const void * element); void * drop (void * set, const void * element); int contains (const void * set, const void * element);#endif The preprocessor statements protect the declarations: no matter how many times we include Set.h, the C compiler only sees the declarations once.

宣布我们能做些什么用一套，我们开始一个头文件Set.h ：＃ ifndef SET_H ＃定义SET_H 外部构造无效*设置；无效*地址（无效*一套，无效*常量元素）；无效*找到（常量无效*一套，无效*常量元素）；无效*下降（无效*一套，无效*常量元素）；国际载（常量无效*一套，无效*常量元素）；＃ endif 预报表保护声明：无论多少次我们包括Set.h ， C编译器将只看到申报一次。

It is different from the finite element method which uses the calculus of variation to construct the element-based approximate equilibrium equation. It does consider the equilibriums of forces on the inter-element boundary, which are neglected in the finite element method through the weak formulation.

这种方法跟有限元素法不同，因为有限元素法是采用变分法建立各个元素的近似平衡方程式，这种方法也考虑元素与元素相连接的边界上的力平衡条件，而在有限元素法的推导过程中我们忽略了这种条件。
