| 摘 要： | 通过对电路板绝缘性能下降的原因和实验数据拟合的分析,说明了周围环境对电路板绝缘电阻有影响。为了准确分析电路设计中可能出现的因绝缘电阻导致的故障,采用曲线分段拟合的算法对试验数据进行拟合。通过对数据的拟合求出了回归方程,并总结出绝缘电阻随时间变化的规律。

| Abstract: | The theory of insulation resistance of printed circuit board and test data show the environments affect insulation resistance of circuit board.Through the algorithm of fragmentary curve fitting,test data is fitted in order to precisely analyse the failure caused possibly by insulation resistance in circuit designs.Through the curve fitting,regression equation is achieved and the rule of the change of insulation resistance following time is concluded. |
