To speak of an educated young person or of a wise young person , rich in the understanding of basic ideas and issues , is as much a contradiction in terms as to speak of a round square 说某个有知识的年轻人或某个聪明的年轻人善于理解一些基本概念和基本问题，如同把圆的说成方的一样，自相矛盾。
The third part analyzed the influence factor of natural gas industry rate structure in china . the fourth part of the thesis mainly studied the natural gas wellhead price of china 论文还指出：依据中国化肥工业的实际情况，对化肥用户的天然气井口价格不宜定的太高；对于其它工业用户可采用成本加成方法确定井口价格。
With aop , common services like logging , persistence , transactions , and the like can be factored into aspects and applied to domain objects without complicating the object model of the domain objects 使用aop后，公共服务（比如日志、持久性、事务等）就可以分解成方面并应用到域对象上，同时不会增加域对象的对象模型的复杂性。

That music should thus be subjected to forms of automation is inevitable ; and that it should remove itself more and more from singing and dancing and embrace a world of sound devoid of human content is surely the end result of believing that music like everything else today is reducible to formulas , to equations , to statistical probabilities , to predictable and controllable functions and behavior - in short to technology 音乐以后会成为自动型式,是无可改变的.它会越离唱与舞越远.相信: [音乐,正如每件事,都可以简化成公式,简化成方程式,成统计概率,成可预期与可控制的功能与行为-简之,就是简化成科技] ,的最后的结果,就是:拥抱,没有人性,的声音,的世界
