要写传热报告，所以写了这个简单的linear interpolation，适用于0~249℃的铜-康铜热电偶（分度号T）热电势-温度线性插值。但愿这个能节省一些打印分度表的纸，节省大家写报告的时间-The write transfer report, write a simple linear interpolation, suitable for 0 ~ 249 ℃ copper- constantan thermocouple thermoelectric power (indexing number T)- temperature linear interpolation. Hopefully this can save some of the the print indexing table paper, saving everyone time to write a report
