本文采用四引线法测量了Bi2223带材临界电流沿长度方向的分布,采用正态分布、对数正态分布、威布尔分布和最小极值分布对临界电流分布进行了拟合检验,确定了临界电流的最优统计分布模型.
In this paper, the four-lead method was used to measure the distribution of critical current along the length of the Bi2223 strip. The normal distribution, lognormal distribution, Weibull distribution and minimum extremum distribution were used to test the critical current distribution. Current Optimal Statistical Distribution Model.
