Here the deriver' self-equilibrium velocity denotes the deriver' desired equilibrium velocity accompanying that the traffic flow is in the equilibrium state. Consequently the adaptive flux model like Navier-stokes traffic equation is derived from the extended Paveri-Fontana equation. Characteristics and the linear stability are analyzed. Numerical solution of the macroscopic traffic equations verifies rationality of our model.

By means of the extended Dirac function, the discontinuous variation in rigidityof the rectangular plate due to the arbitrarily- disposed cylindrical voids is expressed under thecategory of a continuous function.

利用扩展的 Dirac函数，将由于空洞的存在而引起的矩形板的刚度不连续性表示成连续函数的形式，从而实现了不需修正刚度便能写出带圆柱形空洞的矩形板的运动方程。

As the mass emerging of new words, the disyllabic word-formation methods had added more forms, all these led to the change of the basic features of vocabulary.

但是在新词的产生上，单词的这些发展己经不是词汇变化的主流形式，新词的产生己经让位于通过词形扩展的方式形成的双音词。

New, more robust, professional and expandable systems will give scientists effective access to new tools.

新的，更鲁棒的，专业的及可扩展的系统允许科学家有效的访问新的工具。

The one kind of improved FWT algorithm for a finite sequence is proposed after studying theory of multiresolution analysis and analyzing technical characteristics of DSP.

在充分研究多分辨分析理论和分析信号处理器技术特点的基础上，针对DSP TMS320C3X的特点，提出了一种有限序列的FWT的改进算法，详细阐述了信号处理器上FWT的周期性扩展的实现问题，用DSPTMS320C3X汇编语言实现了改进的FWT算法。

A new generalized object oriented Petri net model which can be used to evaluate the capability of equipment support was proposed. Its formal definition was given. The abstract place, abstract transition, message color and the message transferring function between objects were introduced in this model. This model has good modularity, inheritability, reusability, and maintainability, and can reflect flexibility and dynamic features of complex system. An example was given in the paper.

提出了一种可用于装备保障能力评估的增强型扩展的面向对象Petri网模型，给出了该模型形式化描述，引入了抽象库所、抽象变迁、消息颜色以及对象间的消息传递函数等新的概念，更好地体现了面向对象的思想，具有很好的模块性、继承性、重用性和可维护性，能够反映复杂系统的动态柔性特点，最后给出实例。

The author mainly realized the method of generating the large random numbers and judging the prime number using Lehmann means,then three pairs of secure key with different lengths (256 bits,512 bits,1024 bits) was generated to meet the demand of different security grade. In encryption module,modular multiplication arithmetic of large number was realized adopting addition chaining. In decryption module,extended Euclid was used to get inverse,and the Chinese remainder theorem was used to realize decryption,which increased the speed of decryption greatly.

作者主要实现了大随机数的生成、采用整除小素数和勒曼测试法判定素数，可以生成三种不同长度的密钥对(256位、512位、1024位)来满足不同的加密安全等级的需求；加密模块中，选用了二进制序列的乘法方法，实现了大数模幂乘运算；解密模块中，引用了扩展的欧几里德法求逆元，并采用中国剩余定理实现解密过程，大大提高了解密速度。

In the position of the centre city, groundwater water quality demonstrates a kind of gradually stable course; the agriculture planting area along the southern lakeside and the district that the city expanded, groundwater water quality still presents the trend worsening constantly; in the area nearside the grass lake, groundwater water quality demonstrates the situation taking a favorable turn constantly.

在城市中心部位，地下水水质呈现出一种逐渐稳定的过程；在城市扩展的外围以及区内的农业种植区，地下水水质仍呈不断恶化的趋势；而在以草海为中心的区域，地下水水质则表现出不断好转的势态。

Transnational feminist practice is a continued critical intervention of feminist scholars and activists in response primarily to the ever-penetrating processes of globalization: the expanding transnational flow of capital, technology, and people, and the long-existing colonialist/neocolonialist or imperialist mode of knowledge production and circulation.

跨国女性主义实践（Transnational feminism practice）是女性主义学者与积极分子对不断持续扩展的全球化进程的批判性干预。全球化进程主要是指日渐增长的跨国资本、技术、人口的流通，与由来已久的殖民主义/新殖民主义（colonialist/neocolonialist）或帝国主义模式的知识生产及传播。
