Therefore, they also begin to learn and use this simplification language. Although, American English is almost the same as British English, they still have some differences. This situation just like our country, we have many different localisms, which are really difficult to communicate with each other.

英语在众多的英语国家中，各自的方言，俗语层出不穷，当然误解意思的事情也就经常发生，同时在现代的生活中，时间是每个现代人宝贵的财富，传统的英式英语相对复杂，而美式便捷实用，符合的潮流。

Therefore, they also begin to learn and use this simplification language. Although, American English is almost the same as British English, they still have some differences. This situation just like our country, we have many different localisms, which are really difficult to communicate with each other. The same thing occurs between British English and American English.

Moreover,in this dissertation,a method ispresented to control safe basin with the fractal erosion,that is by the application ofthe weak parameter periodic perturbation with an optimal frequency to control thefractal erosion basin,and the analytical study shows that the essence of the methodis that the parameter periodic perturbation can be used to delay the occurrence ofhomoclinic tangencies.

并且在本文提出了一种对分形侵蚀安全域进行控制的方法，那就是应用具有最优频率的参数周期扰动对于已受到分形侵蚀的安全域加以控制，在理论分析中得到这种控制分形侵蚀安全域的方法实质上延缓了鞍点同宿相切的发生，同时考虑了外加噪声对控制后安全域的影响，得到这种控制方法具有很好的鲁棒性。

In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。

She is forced to have sex with the school principal in order to make Gump to go to ordinary school like the normal childreninstead of going to special school, in this part, the film picture gives a distinct vision contrast and audition contrast between the house in dark and the white swing before the gate on which Gump is swinging in school clothes, the voice of Gump's mother and Gump's odd coarse sound, by which, a depressed

她为了阿甘能和正常孩子一样去普通的学校上学而不是特殊学校，被迫与校长发生了关系，影片在表现这一段时让黑夜下的房子与门口白色的秋千上学生打扮的阿甘、阿甘母亲的声音与阿甘嘶哑的怪叫分别形成鲜明的视觉与听觉反差，给人极端压抑的感觉，同时也激发了人们对阿甘妈妈的同情与感叹。

The rate constant k ,the activation energy.and induction period of the transestetifieation reaction for the PET/PEN reactive blend were obtained using a kinetic expression based on a second-order reversible reaction mechanism.

根据酯交换反应程度和不同反应温度下的诱导期探讨了酯交换反应与相容性的关系，认为PET与PEN的相容导致或增强了酯交换反应，即相容性是酯交换的必要条件；同时酯交换的发生又促进了PET与PEN的相容。

These parameters did not differ from each other in figleaf gourd"s two treatments. The root temperature of 14℃didn"t induce significant changes in the total respiration rate in both species but caused an increase of the alternative respiration pathway and a decrease of the cytochrome respiration pathway, and more dead cells in root tips in cold-sensitive cucumber roots.

低温条件下，黄瓜的生长明显差于黑籽南瓜，同时根系表现出更高的超氧化物阴离子O_2~(·-产生速率、过氧化氢(H_2O_2)与膜脂过氧化产物丙二醛含量以及抗氧化酶活性。14℃根温并未引起两种作物根系的总呼吸速率发生变化，但却引起黄瓜根系的交替途径呼吸速率与细胞色素途径呼吸速率的显著变化，表现为低温下Valt的上调而Vcyt的下降。

Under the influences of the Great Schism and Humanism in the 15th century, there were some gradual changes in the late medieval universities, such as the emergence of the university-owned building, the fading of the internationalization and the increasing of the localization, the weakening of the church s control of the universities and the more intervention from secular power; meanwhile, there were also significant changes in the inner organizational form and curriculum content in universities.

在&大分裂&以及15世纪人文主义向大学渗透等因素的影响下，晚期中世纪大学发生了渐进性的变化，如大学自有建筑的出现、国际色彩的淡化和区域性的加强、教会对大学控制程度的削弱和世俗力量对大学干预程度的提高，同时大学内部组织形式和课程内容等也出现了较为明显的变化。
