两维的

At last, it is proved for the two systems that when the control domain U is a bounded, closed set, the reachable set is the same as that when the control domain is the convex of U.It is an advancement for original results.

最后证明了当控制区域U是有界闭集时上述两个系统的等时区域与控制区域是U的凸包时的等时区域相同，推广了有限维的结论。

Along with the evolution of the theory of CIM, the need to intellectualize CIM systems raises. Accordingly, the need to intellectualize enterprise modelling architectures also brings forward. By the research of the 1st chapter, the author discovers that there are three areas in an enterprise modelling architecture can introduce intellectual techniques, viz. modelling framework, modelling method and simulation. Whereas most architectures, such as CIMOSA, ARIS, GIM and PERA, can not satisfy the above-mentioned requirements.

经过第一章研究分析，本文作者发现在企业建模体系结构中的建模框架、建模方法和仿真运行三个方面能够引入智能化方法，即在建模框架中增加通用性维来降低建模难度、缩短建模周期和提高模型的可重用性，在建模方法中全面引入面向对象方法实现建模元素和企业模型两方面的构件化，在模型仿真时应用人工智能领域的成果并提供决策支持。

Such a chaotic attractor was obtained on the phase plane by numerical calculation.

运用数值计算的方法在相平面中得到系统的混沌吸引子，而后对这个混沌吸引子进行数值研究，发现它具有两方面的特征：①它是不连续边界象集的归宿；②具有分数维。

The free volume cell theory was applied to derivative the formula of activity coefficients of liquid binary solution at arbitrary temperature. The Monte Carlo algorithm was employed to calculate the non-liner equations, then the free volume parameters were directly correlated to the activity coefficients of liquid binary, ternary, quaternary and quinary solutions at arbitrary temperature. The three dimensional diagrams of a-x-T diagrams representing the changes of activity with those of temperature and concentration were plotted.

由自由体积胞腔理论推证了某温度下两组分的活度系数关联式；引入MonteCarlo非线性方程解法，通过无限稀释溶液的实验活度系数数据直接得到自由体积参数和二元系及多元系液态金属溶液在任意温度下全浓度范围内的活度数据，构筑了直观反映活度随温度和浓度变化的a-x-T三维图形。

She could see at once by his dark eyes and his pale intellectual face that he was a foreigner, the image of the photo she had of Martin Harvey, the matinee idol, only for the moustache which she preferred because she wasn't stagestruck like Winny Rippingham that wanted they two to always dress the same on account of a play but she could not see whether he had an aquiline nose or a slightly retrouss?

从他那双黑眼睛和苍白而富于理智的脸来看，他是个外国人，长得跟她所收藏的那帧红极一时的小生马丁。哈维的照片一模一样。只不过多了两撇小胡子。然而她更喜欢有胡子，因为她不像温妮。里平哈姆那样一心一意想当演员，看了一出戏后就说咱们老是穿同样的衣服吧。

This algorithm constructs a 64-D crossband vector according to the characteristics of the decomposed image, and adopts nonlinear interpolative vector quantization and soft computing based codebook generation algorithm. Hence, this algorithm can improve the vector quantization performance significantly from both aspects of speed and precision, and it can get a high reconstruction quality (PSNR＞34dB) with a very low bit rate (0.172bpp).

该方案依据图象小波变换的特点构造了64维的跨频带矢量，并采用了非线性插补矢量量化和柔性计算码书生成算法，从速度和精度两方面提高矢量量化的性能，从而在极低比特率的条件下(0.172bpp)获得了高质量的重构图象(PSNR＞34dB)。

This paper first offers a precise definition of the family firm in terms of ownership and control and then categorizes it in the light of the existing literature.

在现有文献的基础上，论文以所有权和控制权为两维对家族企业做了严格的定义和划分，并把研究对象界定在拥有高控制权的家族式企业。

The software with management at present necessary Internet bar basically is an Internet bar software of plan fee system and game update software, and the person that the market of this two place precedes is Shanghai respectively the net dimension Great Master of science and technology of suitable net of the Pubwin of Xin Hao art and Hangzhou.

目前经营网吧必备的软件主要是网吧计费系统软件和游戏更新软件，而这两块儿的市场领先者分别是上海新浩艺的Pubwin和杭州顺网科技的网维大师。

The inspiration of this car is oriented from the 'folding craft', first the designer has to practice the craft that let the paper be folded from 2 diamentional space into 3 diamentionla space; and second, he has to ensure the sturdy of the creases. Besides, there are lots of designing details, and then, an Alcaldes concept vehicle has come out.

设计者设计这款Alcaldes概念车的最初灵感源自于折叠工艺，一方面要实现将一张纸从两维空间折成三维空间，另一方面要保证折痕处的坚硬结实，再加上各种细节出的设计，一款Alcaldes概念车就这样诞生了。

The traditional rule of thumb is that twice as much content takes four times as much resources to develop, says Mr Newell.

纽维尔说，&传统的基本原则说，开发两倍的内容需要四倍多的资源。&

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
