The brief decision rules according with the demands of threshold is directly mined from decision tables based on rough information vector.In this process,decision support ability of condition vector to decision vector is used,and the concrete decision support ability of condition attribute value is not losing.

基于粗糙信息向量，利用条件向量对决策向量的决策支持能力，直接从决策表中挖掘出符合阈值要求的尽可能简洁的决策规则，且不损失条件属性值的决策支持能力。

The combinatorial and delimitative algorithm of engineering structure design with different discrete set and its software system is introduced in this paper.

引 言 离散变量优化设计是指在优化设计过程中，设计变量的取值不是在某一范围内连续变化而是只能取某些符合一定条件的离散值。

First, sources do not worry, as long as there is money to supply software which, of course, top-profits do little because the big market demand for the phone bill, so recharging is not making money, but can quickly enhance the credibility.

首先是货源不用担心，只要软件里面有钱就有货源，当然做充值的利润很小，因为话费的需求市场又大，所以充值不赚钱，但可以快速提升信誉。

The boundary value problem for first-order differential equations with a parameter refers to the finite solution condition of equation which includes unknown quantity and its first-order derivative that not only relies on interval value but also relies on the parameter of the equation,which is always settled by fixed point theory or successive approximation method.

含一个参数的一阶微分方程边值问题是指：含有未知量及它的一阶导数的方程的定解条件不仅依赖于在区间端点的取值，而且依赖于方程中的参数。通常它用不动点定理或逐步逼近法来解决。

Chronic stress could induce disaccord of time to peak value of PS amplitude with EPSP slope.

慢性应激引起PS幅值和EPSP斜率峰值时间不同步，表现为PS幅值达到峰值时间较EPSP斜率提前。

Finding out the maximum point of the equivalent plastic strain on each of the vertical lines, a group of discrete points on the critical slip surface will be obtained. Last, the discrete points are smoothed by means of the thin-plate smoothing spline; and the position of the critical 3D slip surface is determined.

最后，采用被称为薄板光顺样条(thin-plate smoothing spline)函数的插值方法对滑面上的离散点进行了插值光顺处理，在不指定边坡滑动模式和滑面形状的前提下就可以得到三维边坡的临界滑面。

The simulated results indicate that the properties of the chaotic dynamic system are sensitive to the driven frequency. A threshold value of amplitude exists for the appearance of chaos phase. The system is insensitive to the dissipative magnetic force.

数值模拟结果表明：混沌实验摆系统动力学性质灵敏地依赖于策动频率值；系统策动振幅必须大于一定阈值是混沌相出现的必要条件；磁阻尼参数对系统混沌相动力学状态影响不明显。

Once again I want to stress a particular point - there are no specific or fixed settings. There are just too many variables for anyone to give specific 'do-all' settings.

再次强调，没有一个固定的值可以适合各种情况，因为影响补偿值的因素太多，不可能有一个一劳永逸的设置。

This paper provides a method of variable integrity testing to detect the faults of software By checking the definition domain of the variable itself and the restriction condition of consistency between variables, we only need to determine the bound of each output data, rather than the exact value Although the output of testing case cannot be easily caught, this method can improve the efficiency of detecting faults Furthermore, the checking point is not limited to the final output place, but spreads over the reference places in the program code to key variables just like those at the checkpoints under debugging As a consequence, the testing becomes more precise

由于软件测试用例的输出部分很难确定，而通过测试变量自身的定义域和变量间的一致性约束关系，只需要确定输出值的范围而不用知道其确切的值，就可以提高了错误检测的效率同时，检测的范围不局限于程序最后的输出结果，而是散布在程序中的各个有意义的变量，正如调试过程中设置断点观察的那些变量，使得检测错误更加精准1 引言软件测试的本质在于针对要测试的内容确定一组测试用例[1] 测试用例分为输入和输出两部分功能测试和结构测试等基本的软件测试方法，都比较关心测试用例的输入部分定义域的确定，而对测试用例的输出部分考虑得较少例如，边界测试和等价类测试[2 ] 只考虑测试用

Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.

在这一研究内容下，主要研究四个方面的问题：(1)在完成金属波导传输线方程时域形式的基础之上，应用有限积分技术，把波导特征模式的色散传输线方程，化简为一组新的一阶偏微分方程组，该边值问题属一维Dirichlet边值问题，从而便于用蛙跳格式求解，由于是在一维中计算，该方法具有很高计算效率和精度，从而避免了以往为得到金属波导中特征模的时域响应特性，须要求解二阶方程，或用时域有限差分方法求解三维问题的方法，对于后者来说，计算有时是不准确的，或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
