Section 1, the main ideas and developing process of constructivism.

第一部分：建构主义的基本思想和发展路线。

We firstly look back thebirth of SD method,and then present the SD scheme presented by Johnson et.al.forlinear problem to explain the basic idea and implementation:At step 1,we change the testfunctionwhere(1,β)t is the streamline or character direction decidedby hyperbolic operator of the continuous problem,therefore the SD method belongs tothe Petrov-Galerkin method;At step 2,we adopt time-space finite element space,whoseelement is only continuous in space variables x but discontinuous in time variable t.

首先回顾了SD方法的产生过程，然后以线性问题为模型，描述了SD方法的基本思想和具体实现：第一步，将标准有限元方法的检验函数ν改成其中(1，β)t是连续问题的双曲算子部分所确定的流线方向。换言之，SD方法是一种Peterov-Galerkin有限元方法；第二步，采用时空有限元空间，其元素关于空间变量x是连续的，但关于时间变量t仅分段连续。

The basic idea of MLMI is to compute the speaker adapted model of a test speaker by a linear convex combination of a set of speaker dependent models according to maximum likelihood criterion.

其基本思想是，利用语音单元间的相关性，根据最大似然准则由一组说话人相关模型的线性组合得到测试者的说话人自适应模型。

To solve the problem above, we develop a new method to filter signal by performing nonlinear transformation of coordinate and filter of function.

其实现的基本思想是：将一曲线分段，求分段的重心，然后将分段中心的函数值赋给重心。

The basic idea of our method is: By incorporating a drift correction term into the traditional goal energy function, the new algorithm has the natural ability of anti-drift, which then, therefore, can boost the performance of robustness.

该算法的基本思想是：通过引入一个漂移矫正项，来改进传统算法的目标能量函数，使算法天然具备抗漂移的能力，从而提高算法的鲁棒性。

This paper analyze the function and cost of the software product by making use of the basic principle of the value engineering.

虽然不能将传统的价值分析方法直接应用于逻辑产品，但价值工程的基本思想和理论体系对于提升逻辑产品的价值同样具有指导意义。

Its basic idea is to find the shortest path in the channel of cumulation of video bit streams under jitter constrains.

它的基本思想是在视频累积码流的时间抖动约束通道中寻找一条最短路径。

A new approach based on operator decomposition method has been developed to solve nonlinear Helmholtz equation.The approach is applied to compute the magnetic field and eddy current in nonlinear ferromagnetic materials and it provides an analytical solution.

根据算子分裂法的基本思想提出了一种有效的求解非线性亥姆霍兹方程的逼近解析法，对非线性铁磁材料中的磁场和涡流进行了求解，获得了级数形式的解析解。

It accomplishes a signal analysis system based on the theory of softwareradio,which can blindly receive and demodulate several signals as well as abstract useful information.

本项目设计的宽带大动态数字接收机，依据软件无线电的基本思想建立了一个信号处理平台，能够对多种类型的信号进行盲接受和解调，获取其中的信息。

In chapter 2, the basic idea and concept of density functional theory is introduced.

接着在第二章中简单的介绍了密度泛函理论的基本思想和理论。
