Pragmatic presupposition determines the choice of information focus and its position in a sentence,organizes the discourse into a coherent whole,concise,clear and smooth,and achieves the expected stylistic effects.in college english teaching,if teachers teach the knowledge about pragmatic presupposition in listening teaching,introduce the frequently-seen patterns of presupposition, increase the presuppositional sensitivity of students to certain words and structures,guide students to use the theory on presuppositional information to make forecasts on base of written listening material,listen purposefully,and get rid of the distraction of the minor and redundant information,the ability of students to obtain major information and linguistic inference will be strengthened and their listening competence will improve remarkably.george yule divided presuppositional triggers into factive presupposition,non-factive presupposition,counter-factive presupposition,existential presupposition,lexical presupposition and structural presupposition.presuppositional triggers are helpful for us to understand the true intention of the speaker or writer.in college english reading teaching,if teachers introduce the discourse organizing function of pragmatic presupposition and the relevant presupposition triggers,and teach students to use these triggers to communicate with the writer,the comprehension competence of students will be greatly enhanced.the essential function of presupposition is to build a framework for the further development of discourse.in college english writing teaching,teachers can use the theory on pragmatic presupposition to construct a handy training program for textual organization,increase the textual coherence, economy and structural perfection of the english writings by students.in college english translation teaching,teachers should focus on developing the pragmatic presuppositional thinking of students,enable them to grasp the presupposed information in source text / speech exactly,understand the original thoroughly,correctly reorganize and reproduce the pragmatic presuppositions in the target language,carry out the functional equivalence in translation and successfully realize the smooth and accurate communication.with the instruction of pragmatic presupposition in college english teaching,the complete understanding and integral acquisition of english and chinese of students will come true.in conclusion,to implement the curriculum requirements for college english teaching promulgated by the ministry of education of china,we should emphasize the instruction of the theory on pragmatic presupposition in college english teaching,carry it through from beginning to end.it's one of the important means to realize the college english teaching reform, improve the effects of college english teaching,strengthenr the practical and integrative language abilities of students,in order to cultivate the compound talents to adapt to the global integration and meet the requirements of the reform and opening in china.

在大学英语教学中，教师将语用预设知识贯穿于听力教学过程中，讲授一些常出现的预设类型，提高学生对一些特定的词语和结构的预设敏感度，引导学生运用预设信息理论对听力文字材料进行预测，有的放矢，排除次要、冗余信息的干扰，增强获取主要信息的能力和语言推理能力，从而提。。。更多高学生的听力理解水平。george yule将预设触发语分为事实预设、非事实预设、反事实预设、存在预设、词汇预设和结构预设，触发语有助于我们在阅读当中理解作者的真正用意。在大学英语阅读教学中，介绍语用预设的语篇组织功能和有关的预设触发语，并利用触发语来与作者进行交流，会极大地提高阅读理解能力。预设的基本功能就是为语篇的进一步发展建立一个框架。利用语用预设理论可以为大学英语写作教学构建一个易于操作的篇章组织训练方法，提高学生英语写作的语篇连贯性，经济性和结构优化。在大学英语翻译教学中，注重培养学生的语用预设思维，准确把握源语的前提信息，透彻理解原文，使语用预设在目的语中正确重组和再现，实现翻译的功能对等，交际的流畅性和准确性，并增强学生对英汉双语的全面性认识和整体性习得。综上所述，为更好地贯彻和实施教育部颁布的《大学英语课程教学要求》，在大学英语教学中重视语用预设理论的传授，使语用预设贯穿于大学英语教学的始终，是实现大学英语教学改革的重要手段，改善大学英语教学效果，增强学生的实用综合语言能力，培养符合全球一体化趋势，适应改革开放要求的复合型人才。

Why Baidu Hi is such development pouring foreword main is helpless, because the development base of Baidu is a webpage,the search just is searched after obtaining position of a leadership, web2.0 times comes, the success that the network develops is technical advantage not just, capture an user or the user is agglutinant, become a crucial factor especially the arrival of rich passenger times, baidu is timely rolled out Baidu space with a view to to grow end theory, a series of products of Baidu, such as Baidu knows, Baidu is stuck, Baidu space is sealed undoubtedly, just follow the evolution that at the development trend of whole internet network passivity accepts changes of course, baidu knows, Baidu is stuck it is the successful act that duplicates hard undoubtedly what special need is worth to say is, of Baidu space roll out, baidu space justs to be rolled out, show individual character as main factor stresses development, so that locate Baidu space directly later,be the community that make friend, had been apparently be Baidu Hi roll out prepared

百度Hi为什么是这样倒序发展的呢主要的是无奈，因为百度的发展基础是网页搜索只是搜索达到一个领导地位后，web2.0时代到来，网络发展的成功不仅仅是技术的优势，抓住用户或者是用户粘性，成为一个至关重要的因素非凡是博客时代的到来，百度适时推出了百度空间着眼于长尾理论，百度的一系列产品，诸如、百度贴吧、百度空间无疑都是未知的，只是跟随于整个互联网络的发展趋势而被动采取的发展变革当然，、百度贴吧无疑都是难以复制的成功举措非凡需要值得一说的是，百度空间的推出，百度空间甫一推出，就把个性展示作为一个重要因素突出发展，以至于后来直接把百度空间定位为交友社区，已经很明显是为百度Hi的推出做预备了

In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.
