It is not difficult to extract simple information such as road lane mark and the relative position of vehicle on the road from the machine vision sensor, so we have made some improvement on the lane mark identification and tracking technology including using a method based on Zernike Moment line detection algorithm, and then use lane mark features to extract the lane marking feature point, and use linear regression method to extract lane mark parameters.

因为在本文研究中通过机器视觉传感器提取的信息相对比较简单，只是提取公路的车道标识线以及车辆在车道中的相对位置，所以改进了基于机器视觉的车道探测方法，包括文中采用了基于Zemike矩的直线检测算法，然后利用车道标识线特征提取出图像中的车道标识线特征点，再采用线性回归的方法提取出车道标识线参数。

In this paper ,the influence of harmonic to the accuracy of potential transformer and current transformer is studied firstly, and then through some experiments, the new equipment-multifunctional metering of electric energy equipment based on virtual instruments technology and traditional induction Watt\|hour meter to measure the power at different harmonic situations.

首先探讨谐波对仪用电压电流互感器精度的影响，然后通过具体实验，利用新研制的基于虚拟仪器技术的多功能电能计量装置与传统的感应式电能表在不同的谐波条件下同时计量电能，对二者结果进行对比分析，得出谐波对感应式电能表计量影响的准确数据，并总结其规律。

The printed UWB antenna is comprised of a planar monopole radiator and the ground plane which are connected to a coaxial cable to launch RF signals. This kind of ground and antenna system is essentially an unbalanced design, where electric currents are distributed on both radiator and ground plane, and then leakage to the outer conductor of the feeding cable. The impedance matching and radiation pattern will be influenced in the low band, which are our focus. Finally, some techniques will be proposed to reduce the cable effect on the antenna performance.

进行超宽频天线量测时，吾人会利用同轴缆线连接到网路分析仪，这时的同轴缆线不只是扮演一个传输讯号的工具而已，由於单极天线的不平衡结构，对低频而言，接地回流电流会泄漏到同轴接地的导体外部，造成同轴缆线也是一个辐射体，影响到天线低频时的阻抗匹配与辐射特性，因此本论文将探讨同轴缆线对於天线一些参数的影响，并研究提出解决的办法。

We offer base, cello, violin, and then we also do an African music program, where we have incorporated marimbas and Djembe drumming and some other African instruments such as Mouth bow and traditional instruments.

我们提供贝司、大提琴、小提琴，并且我们也接着做了一个非洲音乐节目，在该节目中我们将木琴、Djembe drumming和其他一些非洲乐器混编在一起。

We offer base, cello, violin, and then we also do an African music program, where we have incorporated marimbas and Djembe drumming and some other African instruments such as Mouth bow and traditional instruments.

我们提供贝斯，大提琴，小提琴，然后我们也制作一些非洲音乐课程，在这些课程上，我们混合教了马林巴木琴和金贝鼓及其他一些非洲乐器，如口琴等传统乐器。

We offer bass base , cello, violin, and then we also do an African music program , where we have incoroperated *, incorporated marimbas and * Djembe drumming , and some of the other African instruments like Mouse such as Mouth bow and traditional instruments.

However, there still leaves much to think about the agent systems'software engineering process and methods. In this field, some valuable and important works have been put forward, such as MaSE, Gaia, MESSAGE/UML, etc. Each of them pays attention to one or several aspects of agent system, but few of them give enough thought to the dynamic properties of agent system's role-based organization. Most of these works begin with analyzing system's static role models and transforming them into agent models, and then succeeding make detail design and later implementation.

需要指出的是，在MAS研究的数十年来，研究人员已经对Agent体系结构、意图理论等进行了深入的研究，但也许是出于对人工智能的偏爱，现有的对多Agent系统开发方法的研究不够深入，尽管已经出现了一些广为人知的软件开发方法，比如MaSE，Gaia，MESSAGE/UML等，但这些方法并没有清晰地给出其所依赖的概念模型；此外，在基于角色的面向Agent开发方法中，往往对角色概念以及角色与Agent的关系没有给出明确而深入的刻画。

After remarking that negroes and mulattoes enjoy an immunity from certain tropical diseases, he observes, firstly, that all animals tend to vary in some degree, and, secondly, that agriculturists improve their domesticated animals by selection; and then, he adds, but what is done in this latter case by art, seems to be done with equal efficacy, though more slowly, by nature, in the formation of varieties of mankind, fitted for the country which they inhabit.

当指出黑人和黑白混血种对某些热带疾病具有免疫力之后，他说，第一，一切动物在某种程度上都有变异的倾向；第二，农学家们利用选择来改进他们的家养动物：于是他接着说道，人工选择所曾完成的，自然也可以同样有效地做到，以形成人类的一些变种，适应于它们所居住的地方，只不过自然选择比人工选择来得徐缓而已。

This makes the Chinese culture to pay more attention to the accumulation of previous experience; and some Western countries have suffered foreign invasion, we have experienced Greece, ancient Rome, Alexander the Empire, the Ottoman Turkish Empire ruled four times, culture has therefore broken and more made in the course of cultural development to facilitate the acceptance of different cultures, absorbing, select what they need, and this is the need for a critical, rational thinking, and then to choose in order to fully re-establish their own culture.

这使得中国文化更重视前人经验的积累；而西方一些国家则遭受过异族入侵，经历过希腊、古罗马、亚历山大帝国、奥斯曼土耳其四大帝国的统治时期，文化也曾因此断裂，这更使得在文化发展过程中易于接受不同的文化，博采众长，选取自己所需的东西，而这是需要一番批判、理性地思考，然后才能进行充分地选择，重新建立自己的文化的。

Every household is prepared and then New Year, before the 10 days around the beginning of busy people on the procurement of goods, New Year, including fish and ducks, butter oilnorth and south roasted seeds and nuts, sugar, fruit bait, must buy sufficient, but also prepared to take some pro-Chinese New Year gifts when friends, children need to acquire new clothes new hat, ready to wear the New Year.

然后就是家家户户准备年货，节前十天左右，人们就开始忙于采购物品，年货包括鸡鸭鱼肉、茶酒油酱、南北炒货、糖饵果品，都要采买充足，还要准备一些过年时走亲访友时赠送的礼品，小孩子要添置新衣新帽，准备过年时穿。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
