讨论了弹簧在进行串并联以后性质的变化情况，通过对实际问题应用的分析，使学生明白弹簧的串并联有时只是形式上的串并联，在具体分析题目的时候一定要根据实际情况，灵活处理，切忌乱套公式。本课题的研究可以较好地培养学生分析问题、解决问题的能力。%The properties of the springs in series and in parallel are studied in this paper .By analyzing of the practical problem s ,we can make students understand that sometimes the series and the parallel connection of the springs is a false form .To tackle the specific problems ,one must base on the physical realities and solve them flexibly instead of using the formulas randomly .This work will help the students to develop the ability to analysis and solve problems .
