On the basis of these observation, the author scans again some problems in the classical curricula from the point of view of teaching to indicate that the scientificalness of teaching is not only limited to the demand of knowledge scientificalness. It also requires that the teachers should make individual treatment in order to subliming and abstracting the content of teaching to make it more thoughtful. In this way it can be easily digested and absorbed by the students.

笔者正是基于这样的认识，对数学经典课程授课中的某些问题，重新作以教学上的审视，旨在说明，教学的科学性不仅仅限于对学科知识科学性的要求，它还要求教师对教学内容做再创造处理，使课程内容得到升华，得到提炼，成为思想性的材料，为学生所容易吸收和消化。

The results show that the calibration model established with firstderivative preprocessing spectra was the best, 18 samples of tested set were predicted with this model, the relative standard errors for the prediction of ami no nitrogen, total acid, salt content and color ratio were 1.516%, 1.811%, 1.798% and 1.893%, respectively.

利用聚磷菌在缺氧条件下的吸磷和反硝化作用，实现氮、磷的同时去除，是具有实用前景的城市污水处理方法，而建立活性污泥法脱氮、除磷的数学模型则有利于该项技术的推广应用。

deviation of the antenna radiation resistance seems larger in some textbooks about the electromagnetic theory for the editors have made some similar treatment when discussing the radiation power of short antenna.combining the concept of physical with mathematical tools and the precise results are gained,that is the real radiation resistance of electric dipole antenna is about ten times smaller than that of the approximate results in the actual literature by researching the electromagnetic field theory and average energy density.this offers evidence to grasp the radiated ability accurately.

小 摘要：在部分有关电磁场理论的教材中，编者讨论短天线的辐射功率时，由于作了某些近似处理而所得天线的辐射电阻值偏差较大。从天线辐射的电磁场理论和平均能流密度出发，使物理概念和数学工具相结合，运用矢量运算推导出精确的结果，即电偶极子天线的实际辐射电阻要比文献中的近似结果小数十倍，因而为准确把握天线的辐射能力提供了依据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
