结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其Tg时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that would not crystallize under usual circumstances was obtained, which made the modified PET film to be able to achieve a high degree of orientation during stretching, and it was heat shrinkable when the ambient temperature was higher than its T the effects of different drawing temperature and DR on heat shrinkage of copolyester film was discussed.

" And, even more important,"What can I do to keep a nuclear war from ever happening?

"和，更重要的是，"我能做些什么使核战争的发生？

These and other shocking facts about the products around us -- from household cleaners to toys to food -- are being drilled into consumers thanks to GoodGuide, a startup founded by Dara O'Rourke, a professor of environmental and labor policy at the University of California, Berkeley.

这样那样令人震惊的事情每天都在我们身边发生。—从家用清洁器到儿童玩具到食物—多亏了GoodGuide好导购网站，才使消费者学会了怎样辨别和购买商品。这个新兴的网站是由多拉·欧'罗尔克创建的。他是加利福尼亚大学的一名教授，该大学位于加利福尼亚州的西部城市伯克利。

They would have continued to struggle against economic odds and would have lived in obscurity.

但是他们出人意料地生了个五胞胎，女 1 男。 4 这事使他们的生活发生了根本的变化。

An odorant such as ethanethiol or thiophene is added so that people can easily smell the gas in case of a leak.

一种气味，如噻吩乙硫醇或添加，使人们可以轻松地气味的气体在发生泄漏。

This is, in principle, the same experiment as Oersted's, the only difference being that instead of an ordinary current we have a mechanically effected motion of the electric charge.

在原则上这个实验和奥斯特的是一样的，惟一不同的是他不用通常的电流，而用一种带电体使它发生机械运动。

It is commonly thought that our society had dramatically changed by modern science and technology, and human had made extraordinary pr ogress in knowledge and technology over the recent decades.

人们普遍认为我们的现代科技使我们的社会发生了巨大的变化，近几十年人类在科技方面取得了惊人的进步。

It uses peg-top balance equipment to maintain ombrometer's relative balance,so it can eliminate the impact of the research vessel's shaking.

以普通雨量器为例，如果降雨的时候伴有较恶劣的海况，调查船就会发生剧烈的摇摆，船舶的摇摆会导致固定在船上的雨量器随之摆动，因此会使雨量筒的承水口不能保持水平，改变了雨量筒

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
