The algorithm handles the objective function and constraints separately, and adopts both directional and random search mechanism. It can avoid falling into local optimal point, which may appear in previous bionics random algorithms due to uncertainness of some parameters and/or without guiding search direction.

该算法将目标函数与约束条件分开处理，采用兼具方向性和随机性的搜索机制，避免了已有仿生类算法由于一些参数难以确定和无引导性的搜索方向而陷入局部最优的问题。

Fuzzy support vector machine was applied to solve the unclassifiable problem existing in multi-class recognition by conventional SVM.

针对这种情况，在传统支持向量机中引入模糊隶属度函数，用模糊支持向量机解决了传统支持向量机在多类识别中的盲区问题。

Void unlink{ auto_unlink_hook :: unlink;}bool is_linked{ return auto_unlink_hook :: is_linked;}//The list can't have constant-time size!

定义一个使用基类钩子保存值的链表，该链表不能有常量时间的size函数！

The research work is given as follows. Aiming at the difficulty of traditional form and the lack of the concise and effective mode, the geometry characteristic, the theory of conjugacy and the form of scrolls are analyzed. A general describing mode of scrolls based on Whewell equation is presented on the design of profiles.

主要在以下几个方面进行了研究工作：针对采用传统方式描述的型线表达形式各自相异，缺乏简洁有效的型线通用模型，重点研究分析了涡旋型线几何特性、构成形式与啮合理论；提出了基于Whewell方程的涡旋型线通用曲线函数类表征形式。

本文应用数理统计方法中的回归分析和聚类分析，对自然地理要素间关系和地理类型的划分作了初步的定量分析。在回归分析中，应用我国山地的降水资料建立了地形高度对降水影响的数学模型，得出山地降水垂直分布规律服从于线性、幂函数、指数函数和对数律。

By Independent-subsystem method, the results of existence and global attractivity of a positive periodic solution are obtained.

本文运用重合度理论中的Mawhin延拓定理或系统的持久性结果得到了几类种群生态学模型正周期解的存在性条件；并通过构造Lyapunov泛函(或Razumikhin函数)研究了某些模型正周期解的全局吸引性。

The results showed that loading Ag^＋, Ni^2＋, Cu^2＋ or Zn^2＋ ion on the activated carbon obviously improved its adsorption of benzothiophene, while loading Fe^3＋ or Co^3＋ ion on the activated carbon caused a decrease in its adsorption of benzothiophene in comparison with the original unloaded activated carbon, which was due to the variation of the nature of soft and hard acid on the surface of the activated carbon.

采用密度泛函数理论法计算结果表明，苯并噻吩的电负性χ为2.638，属软碱类物质；由于Ag^＋为软酸，活性炭负载Ag^＋离子，增加了其局部表面的软酸，从而增强了对苯并噻吩硫化物的吸附；由于Ni^2＋、Cu^2＋和Zn^2＋离子属交界酸，负载Ni^2＋、Cu^2＋、Zn^2＋离子增加了活性炭表面的交界酸，也在一定程度上提高了其表面对苯并噻吩硫化物的吸附；当活性炭表面负载了硬酸性Fe^3＋或Co^3＋离子，其局部表面硬酸增大从而降低了其对苯并噻吩的吸附。

Taking a example for verilying the feasibility and computation precision of the approach,the computation results show that the PSO-based approach is a useful tool for solving such nonlinear optimization problems as cylindricity evaluation with complicated goal function and more parameters. It is superior to that given by the Least Square Method and a little better than or equal to those given by GA-based method and another Minimum Zone Method.

计算结果表明，该方法对于圆柱度误差评定这类具有复杂目标函数和较多参数的非线性优化问题有很好的计算性能，优于最小二乘法；与遗传算法和其它满足最小区域条件计算方法相比，计算精度略优于前者或者与前者相当，能够获得精度较高的结果，而突出优点是简单，易于实现而且计算效率较高。

The fact that namespace definitions can be discontiguous means that we can compose a namespace from separate interface and implementation files. Thus, a namespace can be organized in the same way that we manage our own class and function definitions

命名空间定义可以不连续意味着，可以用分离的接口文件和实现文件构成命名空间，因此，可以用与管理自己的类和函数定义相同的方法来组织命名空间

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
