tuning constant meaning in Chinese

细调常数

By close study on the average temperature rise , temperature distribution , and tune constant of the class f resin dry type power transformer ' s high voltage and low voltage winding under self - cooling and wind - cooling mode , we find out the connection between the variation of the load and the items , mentioned above . the results of the experiments can be reference to both thermal design optimization of dry type power transformer and the revision of current standards . meanwhile , we develop the software , which can predict the overload ability of the dry type power transformer
本文对f级树脂浇注式干式变压器的高、低线圈的平均温升，内部温度分布和时间常数在自冷和风冷，两种冷却方式下随负载变化的规律进行了研究，得出了平均温升、热点温升和时间常数随负载变化的相互关系和有关计算用参数和公式，试验结果可作为改进干式电力变压器的热设计的依据和对现行标准进行修改的参考。
