Finite Element Method is an important means of engineering subject and has been proved to be a common method in many subjects. However, disadvantages still remained. During the structural analysis, large amount of high-order units were used in order to ensure the precision of arithmetic solution when using Finite Element Method to do discrete processing. This will cause high order of coefficient matrix of corresponding equation group.

有限元方法是工程学科的重要工具，被证明为在许多科学和工程领域中连续物理系统模拟的一种普遍方法，但缺点是随着工程结构分析问题越来越复杂，在结构分析中，为保证数值解的精度，在使用有限元方法离散处理时，往往要用大量的高阶单元将结构剖分得很密，这时相应的代数方程组的系数矩阵的阶数很高，即使用目前速度最快的串行机来进行求解，费时仍然太多且问题的规模受到内存容量的限制。

One should always make a clear and contrasting distinction between the Saturnian type of organization which integrates a number of component units of a more or less similar nature within a relatively narrow and sharply defined field, and the Neptunian type which relates essentially different entities — each of which has its own roots and particular outlook — into some sort of large-scale federation.

每个人都应具有明确和鲜明的个性——与土星性格试图抹平每个独立化的单元，那些试图连接相同或迥异的自然，在其内部显然存在着狭窄和尖锐的界限的事物不同——海王星性格将诸多明显不同的事物紧密联系起来——使每件事物都具备自己的根性和独特的外表——并将其溶入更大规模的联盟中去。

Most of community detection algorithms are used in dealing with unipartite networks, and there are few algorithms designed for detecting communities in bipartite networks, and these algorithms have some weaknesses respectively. For example, the community detection algorithm proposed by Guimera can not utilize weight information of a bipartite network; the algorithm proposed by Barber can not deal with the complex mapping situation of communities in bipartite network.
