大改变

It may be a big task to study the change, yet we shall go for growing seaweed in the sea.

它可能是一个大的任务，以研究改变，但我们将继续免费为海藻生长在海中。

This is achieved by avoiding changes in metal flow direction and large expansions or contractions of runner cross sectional area.

这能通过避免金属流动的方向改变和避免过大加大或缩小横截面积来达到。

As a new subject, many aspects of ecosystem health are in the seedtime.

工业文明以来，人类以前所未有的规模和强度影响环境，改变甚至破坏自然生态系统，致使生态系统的健康受到越来越大的损害，引发了一系列的全球性环境问题，由此危及到人类自身的生存，这促使人们认识到维护与保持生态系统健康，促进生态系统良性循环的重要性，使生态系统健康成为当今学术界重点关注的研究领域之一。

With the teaching method, the teaching is more close to the development of society, the teaching activity in classroom is more effective, and the student' s self-educated way becomes better and effective. This...

实践证明，这种教学方式更能紧跟社会经济的发展和需求，不仅课堂教学效果好，知识流密度大，而且还改变了学生的自学方式，提高了学习兴趣和能力，为构筑现代化的教学系统打下了基础。

ANYONE who thought that his wife's run for the presidency would cause Bill Clinton to avoid the limelight has been proved utterly wrong. September began with the publication of the former president's book,"Giving", about "how each of us can change the world", and will end next week as he takes centre stage at a celebration of philanthropy self-effacingly called the Clinton Global Initiative.

事实证明，假如有人以为比尔·克林顿会因为夫人竞选总统就不会再抛头露面，那就大错特错了。9月初，这位前总统就"一己之力如何去改变世界"所著的《给予》一书正式出版；下周也就是9月底，随着谦称为"克林顿全球计划"（Clinton Global Initiative，CGI）的慈善机构的一项庆典活动开幕，他又将成为世人瞩目的焦点。

But, while some consider these threats as self-evidently the main challenge to world peace and security, others feel more immediately threatened by small arms employed in civil conflict, or by so-called "soft threats" such as the persistence of extreme poverty, the disparity of income between and within societies, the spread of infectious diseases, or climate change and environmental degradation.

有些人认为，这些威胁显然是对世界和平和安全的最大挑战，其他人觉得受到国内冲突中使用的轻型武器的威胁，或者是"软威胁"：比如持续的贫困、国家与国家之间以及国家内部各阶层收入的差距、传染病的传播以及气候改变和环境恶化。

If a large parrot has not been socialized by the teen years, the bird's instincts to reproduce, along with the habitual self-rewarding behaviors that have developed, can challenge or defeat efforts to train the bird.

如果一只较大的鹦鹉没有在青春时期被社交化，那么鸟类的本能将会重现，并随着习惯性的自我激励来产生行为发展，而且会通过改变努力训练但失败的鸟。

The proof that the state is a creation of nature and prior to the individual is that the individual, when isolated, is not self-sufficing; and therefore he is like a part in relation to the whole.

举个例子吧，你小时候有个很好的朋友叫张三，张三初中毕业之后就出去大城市打工了，从一种环境到另外一种环境，他的本质因为环境的改变发生了变化。

Figure 10.1shows typical layouts of interchanges at three-legged junctions.The geometry of the interchange can be altered to favor certain movements by the provision of large turning radii and to suitable topography of the site.The trumpet interchange has been found suitable for orthogonal or skewed intersections.Figure 10.1a favors the left turn on the freeway by the provision of a semidirect connecting ramp.

数字10.1shows典型的布局交汇处，在三条腿的junctions.the几何的交汇处可以改变偏袒某些运动所提供的大转折半径和合适的地形的site.the小号交汇处已找到适合的正交或倾斜intersections.figure 10.1a ）有利于左转，就在高速公路上所提供的半连接匝道。

The result of this experiment showed that expected segmentation result could be achieved by using BP network method. After taking further processing such as picking up bigger areas, erosion and dilation, etc., the result could be better. Moreover, if the teacher signals were changed, the image segmentation of peduncle or sepal could be realized easily.

试验结果表明，利用BP神经网络能较好地实现成熟草莓果实与背景的分离，经过提取大区域和腐蚀、膨胀等算法的进一步处理后，效果更好；而且，只要改变训练时的教师信号，即可实现对草莓果梗、萼片等图像的分割。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
