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。

Comparing the run_time between insertion sort and quicksort shows insertion sort gives better performance when the given data sequence is in ascending order. For the nearly sorted list, whether insertion sort performs better than quicksort depends on the size of the list and the number of randomly ordered items. Compared to the insertion sort, the results show quicksort yields shorter run_time if the list is in descending or random order. The main drawback of quicksort is the worst case behavior of O(n2) comparisons when the list is in ascending or descending order. It has been shown that quicksort also performs poorly for nearly sorted list.

通过插入排序和快速排序执行时间比较显示：当序列以递增次序排列时，插入排序的表现比快速排序好；对于基本有序序列，插入排序算法是否比快速排序算法好取决于序列的大小和基本有序序列中随机分布元素的多少；对于递减和随机序列，快速排序的运行时间比插入排序好。

With internationally latest studies, the paper also proposes some biquadrate filters which are capable to perform the functions of second-order low pass、 high pass、 band pass、 band stop、 all pass filtering by selecting one of the three inputs or their proper combinations from the same configuration, furthermore whose natural frequency and the quality factor can be tuned independently. Then a continuous-time biquadratic filter using CCCII is proposed, which can be used in hearing aids and in other analog signal processing applications. Lastly a current mode and a voltage mode novel n-order filters of multifunction are presented. Not all both of the n-order filters are electronic tunable,but also they are integrated conveniently and compatible with VLSI technology.
