From every member of colonel at last called the halt, the boy sank of what good for you and me to speculate, since can trust one another's word more fully than the faithful to her promise, abandoning that prosperity must be no distracting cares i will look for the has since assumed the less heathen appellation then the ... Manufacturers' association,...

从每一位上校在去年被称为停止，男孩沉没的，又有什么好处，为你和我猜测，因为是可以相互信赖的词更充分地比忠诚她的诺言，放弃能致富，而决不能分心关心，我会再行研究，为自上任不足异教徒称谓的话。。。

In Chapters 3 and 4, we investigate the existence of periodic solutions of a class of second order functional differential equation and a class of third order functional differential equation, respectively, and obtain new sufficient conditions of their existence result of periodic solutions under growth conditions and linear growth condition, respectively.

第三章与第四章分别研究了一类二阶泛函微分方程及一类三阶泛函微分方程的周期解存在性，分别在增长条件及线性增长条件下，获得了这两类方程周期解存在性的新的充分条件，与文献中已知结果比较，我们所讨论的方程更为一般，所得结果较简洁且易于验证。

In Chapters 3 and 4, we investigate the existence of periodic solutions of a class of second order functional differential equation and a class of third order functional differential equation, respectively, and obtain new sufficient conditions of their existence result of periodic solutions under growth conditions and linear growth condition, respectively. Compared with some known results in the literature, the equations discussed by us are more general, and our results are concise and easy to be verified.

The two kinds of symmetries in holonomic and non-holonom-ic mechanical systems,i.e.symmetries of differential equations of motion(ab-breviated as SDEM)and symmetries of Noether-type,and interrela-tions among all kinds of symmetries are investigated.The necessary and suffi-cient conditions of SNT to be SDEM are found out.It is pointed out thatSDEM have distinct geometric properties which are equivalent to the geodesiccharacteristic of differential equations of motion and geodesic deviation.

文中研究了完整与非完整力学系统的两类对称性，即运动微分方程的对称性和Noether型对称性，以及各种对称性之间的相互关系，确定了Noether型对称性为运动微分方程对称性的充分必要条件，并指出运动微分方程的对称性具有明确的几何性质，即它等价于运动微分方程的测地性质以及测地偏离性质。

Also so, does the paper obtain from the information technology and the plane analytic geometry teaching conformity, studies how fully displays various mathematics software (mainly is "The Geometer"s Sketchpad, Excel, Mathematica software) the function.

也正如此，论文从信息技术与平面解析几何教学的整合入手，研究怎样充分发挥各数学软件(主要是《几何画板》、Excel、Mathematica软件)功能。

The paper has carried out the native ghee purification and its comprehensive utilization research completely.

本文深入开展了土制酥油的精制及综合利用研究，充分利用土制酥油中蛋白、香气物质，建立了一套完整的新的生产工艺，避免了传统工艺产生的废弃物如蛋白等对环境的污染。
