Although they are different from the geminations of compound words, such as "Jia Jia"("every family" in Chinese),"Ren Ren"("everyone" in Chinese) and so on, mentioned in some middle school teaching materials, we still believe that words like "Guo Guo"("katydid" in Chinese) or "Xing Xing"("gorilla" in Chinese) are single morpheme words, and "Ba Ba","Jia Jia", etc., are compound words, which are actually correct viewpoints in the college teaching book.

虽然它与中学教材中提到的合成词中的重叠式"家家"、"人人"有所不同，但是经过研究我们依然坚持大学教材中的"蝈蝈""猩猩"等是单纯词；"爸爸"、"家家"等是合成词的观点是正确的。

During the course of the well-known "new mathematics" campaign, the status of Euclidean geometry was completely overthrown in I960" s. After deeply thought of "new mathematics", the standpoint that geometry curriculum should reflect the content and method of modern geometry and be in touch with the student" s real life was agreed on. Other countries have tried some significant attempts. We can find from some geometry textbooks that the methods of transform and vector have appeared as a normal part. Simultaneous, not only the new developments of geometry such as Topology have been referred , but also the connection between geometry and practice has been strengthened.In China, geometry curriculum is also in the during of innovation.

而学校几何课程在二千年的时间里一直没有多大的变化，直到二十世纪初"克莱因—培利运动"的第一次冲击，到60年代"新数学"运动的全盘改革，以及之后的深入反思，中学几何课程要反映现代几何学的内容和方法以及紧密联系于实践的观点已经受到普遍的重视，国外的几何课程已经在这方面做了不少有意义的尝试，从国外的一些几何教材中可以发现：变换、向量等工具已经作为正式的内容进入几何教学，拓扑学等几何的新发展也开始在教材中有所体现；几何课程与实践之间的联系更是在很大程度上得以加强。

At present, many text books that have been published in the my home country or foreign country, especially the Signals and Systems writing by Oppenheim A V and Signals and Systems writing by Haykin Simon, introduced the methods by use of the graph to determine the up limit, low limit and the exist interval of the integral or convolution sum.

目前国内和国外出版的《信号与系统》教材，特别是电子工业出版社出版的两位著名学者Haykin Simon。和Alan V.Oppenheim分别写的教材《Signals and Systems》都采用图解的方法求解连续信号的卷积积分和离散信号的卷积求和。

At the beginning , this thesis has had a rough study about many Chinese and American teaching material; Then select two sets which are best-known in each country, and have an comparison between them in detail, which includes contents system, the pattern of discussing, the art of illustration, the arrangement of examples and exercises, the character of fitting for teaching, including the contemporary Physics knowledge and the development about students Physics intuition and perspicacity .etc.

本文通过对中美多套教材的宏观研究，再对其中的两套在各自国内流传较广的物理教材，从内容、体系、论述方式、插图艺术、例题与习题、可教性、包含现代物理前沿知识及培养学生物理直觉与洞察力等方面进行了详细比较，总结了它们的各自特点。

It, with the traits of "fusion of mood and scenes" in manifestation,"reciprocal transformation and promotion of nihility and actual being" in structure,"lingering charm" in appreciation,"presenting life rhythm" in nature, is the pursuit of artists.

本文以"意境化课程"来指称"以意境为隐喻的课程设计活动，即在课程价值上倡导以关注人的生命存在为最终旨归；课程设计中强调借鉴艺术创作规律，运用"虚实相生"、"立象尽意"等艺术创作手法；教材设计和课程实施中提倡布白与创设情境，倡导教师，教材和学生的体悟和视域融合；课程评价中推崇导向美学精神的理念"。

In recent years,medial average has still not been introduced in Sports statistics,which is used as a textbook in institutes of P.E. On the basis of analyzing the nature of medial average ,the author proposes that medial average is commonly got using average rates in sports researches because of its features and laws. Since medial average is gained by reciprocal of its observation value,a quick method of arithmetical average might be medial average equals to...

对近年来未把调和均数列入体育院校《体育统计学》通用教材提出了不同的看法，认为根据体育运动的特点与规律，在体育科研中，利用速率计算均值的情况较多，由于调和均数是应用其变数值的倒数来计算算术平均数，所以在加权正确的情况下，调和均数与算术均数计算结果相等，是算术均数的简捷计算方法，应该向学生介绍调和均数并列入教材。
