| 摘 要： | 对《力学》中的物体自由度进行多方面分析,以深化教学、提高学生正
确分析物理问题的能力.使用实际教学分析的研究方法，在《力学》范围内讨论自由度与坐标、
自由与约束的关系并得以下结论:
(1) 同一物体的自由度随其所在的``空间'不同而不同, 不因坐标系的选取不同而
异, 在同类参考系中不因参考系的动静而有别；(2)自由度遵循叠加原理.
讨论了质点系的总自由度及相关计算问题，并指出研究《力学》中自由度的意义.

| Abstract: | Firstly ,the degree of freedom of mechanics of university physcis from different degrees and angles are analysed in this paper. The studying methods are:(1)The characters of degree of freedom are introduced of mechanics .(2)The degree of freedom in the field of mechanics of university physcis are as following:1)The connection between the degree of freedom and coordinate is pointed out.The relation of free and restriction is listed.2) The number of degree of freedom of the same body changes along with its space changes by taking for examples. 3)The adding rules of degree of freedom are showed.4) The total number of mass point group is talked .5) The methods of calcilation of degree of freedom of mechanics are showed.Finally,the studying significance of the degree of freedom of mechanics of university physics is showed . |
