Antifreeze

An antifreeze is a liquid that is added to water to keep it from freezing. When water freezes and turns into ice, it expands. The force of water expanding is so great that it will break the hardest metal. Water is used in car engines to keep them cool while they run, and if this water is allowed to freeze in the winter, it can break the iron block of the engine. That is why antifreezes are necessary.

机器人

Scientists have written a report on the future of trade and industry. They talk about the role robots will play in industry.What is a robot？Basically，it is a machine which is de-signed to do the work of a human being. It is usually controlled by computer. Once it has been given a set of things to do，it will do the job on its own.Nowadays，Britain has 120 robots at work in industry. This compares badly with other industrial countries. In Japan，there are 4，000 robots in use. In the USA …

Chinese New Year

Chinese New Year is the most important and longest holiday in China.Chinese will begin celebrating on the New Year's Eve and the celebrations will last for 15 days. The Origin1 Chinese New Year is the first day of the lunar calendar2,so it is also called the Lunar New Year.And it is also referred to as the Spring Festival since it is the beginning of the Spring term,which is the first term of the 24 terms on the lunar calendar.     

On the Impact of Western Festivals on Traditional Festivals in China and the Reform of Chinese Festivals

As China steps up its reform and opening up to the outside world,Chinese,especially the young,are becoming increasingly interested in western festivals.However,some traditional festivals in China are left out in the cold.This paper is mainly on the effect of west ern festivals on traditional festivals in China,trying to analyze the reason why it becomes this and it will lead us to face the communion and mixture between the two parties rationally.From the perspective of folk culture,it is necessary for us to find the motive of reform of Chinese traditional festivals.     

Do you know?

Ⅰ.What will the weather be like? What will the weather be like? Some people say they can know what the weather will be like from birds.When they see birds fly high out to the sea,they know it is a nice day,because birds don't like to fly out when it will rain.When the weather will be bad,the birds come back to the beach.A big wind may come with a rain.Birds do not like to fly in a big wind.They may sit in a tree when rain is coming.Other animals can also tell the weather.If it's a cloudy day and the rain is coming,chickens aren't quiet,and they are running here and there.Frogs(青蛙) are making big noise in the pool.If it is a nice day,the frogs will come out of the water.

A Study of linguistic Taboos in Intercultural Communication

As the globalization is rapidly developed,intercultural communication has become more and more intensified.When it comes to the case of taboo,it varies from one culture to another,thus,the violation of taboos will cause something unpleasant,like misunderstanding.So people should pay more attention to it.This essay just takes some linguistic taboos in Chinese and English to compare the two kinds of taboos to give deeper illustration to readers.It is hoped that the readers could make full use of this knowledge to communicate effectively in intercultural communication.

双正、双负和单负介质光子晶体能带的比较研究

利用传输矩阵法理论,对双正、双负和单负介质构成的对称结构光子晶体能带谱进行了对比研究,结果得到：由不同介质材料构成的对称结构光子晶体,其能带谱存在很大的差异,其中以单负介质光子晶体禁带宽度最宽,双负介质光子晶体次之,双正介质光子晶体的禁带宽度为最窄;当周期数变大时,光子晶体禁带中的透射峰带宽均逐渐变小并趋于尖锐,且以单负介质的光子晶体透射峰带宽减小的速度为最快;介质厚度dB对单负介质光子晶体的调制效果要优于对双正和双负光子晶体的调制效果;入射角对单负介质光子晶体能带谱的影响要大于对双正和双负介质光子晶体.不同介质材料构成的对称结构光子晶体的这些光传输特性,可为镜像对称结构光子晶体的设计以及窄带或是宽带光子晶体光学滤波器件等提供理论指导.

从定位到安于其位

不同的"位"决定了高校在高等教育结构中不同的功能.真正的定位发生在多重博弈之后.安于其位,就是各个高校要根据市场需要、国家要求以及自身的条件做到安于职守、各司其职.安于其位的前提是正确理解"位"的差异性问题,防止高校盲目追求"上位";安于其位的核心是组织认同;安于其位的保障是制度.     

夫子“与点”之叹,乃退隐之叹——谈《侍坐》章究竟表现了孔子怎样的人生态度

夫子“与点”之叹主要有三解 :其一 ,孔子“善点之言 ,欲以雩祭调和阴阳” ;其二 ,“孔子与点 ,盖与圣人之志同 ,便是尧舜气象” ;其三 ,孔子与点 ,善其独知时也。以《论语》证之 ,一说有违孔子的天道观 ,二说不符合孔子大同理想的最高追求和现实中的实际目标。只有第三种说法符合孔子进退行止的人生态度和理想追求 ,实乃孔子真意     

论思维的三重制约关系与辩证思维方式——兼谈辩证逻辑的一些问题

人的思维处在与主体、与客体和与自体的三维制约关系中：主体维与对象维结合形成思维中的认识,这是认识论的课题;主体维与自体维结合形成思维中的逻辑,这是逻辑学的课题;而对象维与自体维结合则把认识与逻辑统一了起来,形成思维的具体运行方式,这是思维方式论的课题。当思维客体是辩证的且以辩证思维方法加以把握时,就会形成辩证思维方式。这就是辩证逻辑的对象。它从在本质上是关于辩证思维方式研究的应用逻辑。
