摘　　要：某进口液氢输液管压力与温度的联锁报警条件为幂运算函数关系式,存在计算不便或计算速度较慢的问题。首先进行了压力数值的单位换算,并列举了温度报警上限。根据已知数据,利用最小二乘法进行直线拟合,得到了近似的线性函数关系式,使该液氢输液管的温度报警上限得到了快速而准确的设定,取得了良好的效果。The operation interlocking alarm condition of the data of pressure and temperature from an imported liquid hydrogen infusion tube was a power operation function relationship.There was a problem of inconvenience or slow calculation speed.First,the unit conversion of the pressure value was performed,and the upper limits of the temperature alarm were listed.According to the known data,the least square method was used for linear fitting,and an approximate linear function relationship was obtained,so that the upper limits of the temperature alarm of the liquid hydrogen infusion tube could be quickly and accurately set,and good results were obtained.
