In this book, it is shown that the freeduan.com methods developed by the author for the close study of mathematical cuneiform texts can also be successfully applied to all kinds of Egyptian mathematical texts, hieratic, demotic, or Greek-Egyptian.

在这本书里，显然freeduan.com 方法发展通过数学楔形的正文的仔细研究的作者也能被成功适用于各种埃及数学正文，hieratic，通俗，或者希腊语埃及语。

This paper analyzes the actual problems in present higher mathematics taught in universities of science and technology.

本文通过对目前理工科大学高等数学教学中存在的问题进行了分析，吸取了这方面改革的部分成功经验，总结了自己在教学过程中积累的经验，提出了对高等数学教学改革的一些建议。

And the concept teaching plays a vital role in higher mathematics teaching.

数学概念教学在高等数学教学中占有重要地位。

Finally, this paper discusses how to integrate the thought of the mathematical modeling into the teaching of higher mathematics courses.

最后，就如何将数学建模的思想融入到高等数学等课程的教学活动中做了一定的探讨。

The project proposed and established the strict unique mathematical model of instantaneous frequency aiming at the currently existed problems in Hilbert Huang Transform form the viewpoint of physical connotative meaning; proposed and established the strict mathematical model of general intrinsic mode signal based on the concept of general continuous intrinsic mode signal and the compositive principle of practical general intrinsic mode signal; researched and proposed the fitting method of envelope lines in HHT from the viewpoint of theory, conquered the blindness and random in quondam EMD envelope line fitting and boundary treatment; developed a virtual time-frequency analyzer based on general intrinsic mode signal decomposition to open out the local time-frequency characteristics of nonlinear and nonstationary signal more deeply and accurately.

本项目针对希尔伯特-黄变换现阶段存在问题，从物理内涵的角度提出并建立了瞬时频率严格的唯一的数学模型；基于连续性的一般固有模态信号的概念和实际信号的一般固有模态信号的组成原理，提出并建立了一般固有模态信号严格的数学模型；从理论角度研究并提出HHT中的包络线构造方法，克服了原EMD的包络线构造和边界处理的盲目性和随意性；研发一台基于一般固有模态信号分解的虚拟式时频分析仪，使之可以更深入、准确地揭示非线性非平稳信号的时频局部特征。

After a year of doing part-time hobbyist catch-up math, you're going to be abl

在做了几年的业余数学爱好者之后，你打算做更多的数学，甚至你从没碰过铅笔和纸。

After a year of doing part-time hobbyist catch-up math, you're going to be able to do a lot more math in your head, even if you never touch a pencil to a paper.

在做了几年的业余数学爱好者之后，你打算做更多的数学，甚至你从没碰过铅笔和纸。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
