This method uses the strong non-linear mapping ability which the RBF network has and its short-time training merit to construct the network, substitutes the non-analytic function, make it to instate of the optimized question of the objective function, and iterates this objective function with the genetic algorithm to search the optimal solution.

该方法利用RBF网络所具有的非线性映射能力强，训练时间短的优点，构建网络，替代非解析函数，使之作为优化问题的目标函数，并用遗传算法搜索迭代出该目标函数的最优解。

In the designs of time, emotion has very important functions. Along with the development of computer, network, digital and electronic technologies in 1990s, non-substance designing has became a leading trend. Computer has replaced paper and pencil to become the main instrument, also the software has turned into a part of design. More important thing is the designs of physical products commence to hanker for lyric-value, advocate the designs that can arouse poetic responses and focus on the non-substance services, technique and audio-visual feeling. Design subject has already speared the evaluative trend from applied material engineering, technical science and functions of products and other physical modality and value to intangibleness such as services, technique, culture, emotion, poetry and so on.

情感在当代设计中有极其重要的作用，90年代，随着电脑等电子技术和数码、网络技术的发展，非物质设计成为设计的一个主导倾向，不仅设计的工具从手绘工具变为电脑，软件成为设计的一部分，重要的是物质产品的设计也开始追求所谓的抒情价值，提倡"能引起诗意反应的物品"的设计，注意非物质的服务、方式、视听感受等方面的设计，设计学科已出现从实用的材料工程科学、技术科学、产品功能等的物质形态和价值转向服务、方式、文化、情感、诗化等无形的非物质方面的趋向。

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。

I also realized the nature of similarity-and-continuity, and the non-permanace-and-non-nihility of all beings in the course of evolution: every individual arises and falls interdependently in a continuous way, like the foams in the river of life that flows everlastingly.

当时，我似乎感受到我和鳄鱼等爬虫类、马等哺乳类等无比的亲密关系，再次憾动"我是万物之灵"的迷执，更小心、踏实的去面对人类隐藏在深层的本性；同时也体会到生命各物种间之相似相续、不常不断的演化过程，生命个体犹如生命之亘古长流中的水泡，缘起缘灭，不生不灭。

The intergrowth of the non-profit organization operated by official and civil non-profit organization is present a social fact in our country.

既然我国的非营利组织存在官办与民办之分，那么，对二者进行比较研究就有着重要的现实意义。

Based on this definition, it is concluded that community public products are a kind of special social intervenient products between pure public products and pure private products. Therefore, they have the characteristics of partly-non-exclusiveness, limitedly-non- rivalry, selectivity, and openness.

通过对社区公共产品概念的界定，我们知道，社区公共产品是介于纯公共产品和纯私人产品之间的一种特殊社会产品，它具有局部的非排他性、有限的非竞争性、可选择性和外部性的特征。

In high-impedance current-input inverting configurations, where a length of shielded wire is used to guard the lead from the current source to the amplifier's inverting input, the guard should either be driven by a buffer at the same potential as the non-inverting input, or be tied directly to the non-inverting input, with a second outer shield connected to the signal's reference point.

如果将运放接成反相放大器的形式，并且在信号源与运放反相端之间用一段带有屏蔽层的导线来充当的防护罩，那么对防护罩的处理有两种选择：要么用一个缓冲跟随器来驱动，跟随器输出端与运放同相端电位相等，而且除跟随器外，防护罩不与其他点接触；要么将防护罩直接接到运放的同相端，然后在其外面加一个屏蔽层，并且将屏蔽层连接到信号的参考电位。

The invention discloses a DC/DC circuit, comprising a PWM controller, a current amplifier, a peak current comparator, an error amplifier, a main switch, a synchronous switch and also an operational amplifier. The non inverting input end of the operational amplifier is used for coupling with input voltage or voltage reference, or used for coupling with the input voltage and the voltage reference; the inverting input end of the operational amplifier is used for coupling with the voltage reference or ground, and the output end thereof is connected with the non inverting input end of the error amplifier.

本发明公开了一种DC/DC电路，包括PWM控制器、电流放大器、峰值电流比较器、误差放大器、主开关和同步开关；还增设运算放大器，其同相输入端用于与输入电压或基准电压耦合，或用于同时与输入电压和基准电压耦合；其反相输入端用于与基准电压或地耦合，其输出端与所述误差放大器的同相输入端连接。

The decimal form of an irrational number is a non-repeating and non-terminating decimal number.

一个无理数写成小数形式是无限不循环的。

Three counter-examples of topological space are proposed in this study: There are two metric spaces, X and Y, in which and are isometric, whileand are not isometric; Non-metric tight regular space is a counter-example of the separation of topological space; No non-zero continuous linear functionals of the linear topological space is a counter-example of linear topological space.

这里给出三个反例，存在两个度量空间X与Y，使X^2与Y^2等距而X与Y并不等距是拓扑空间中的反例；存在不可度量化的紧的完全正规空间是拓扑空间分离性的反例；不存在非零连续线性泛函的线性拓扑空间是线性拓扑空间的反例。
