依据GB/T 3965-2012分别采用水银法和热导法对熔敷金属中的扩散氢含量进行了测定，对两种方法的测定结果进行了比较，并运用数理统计方法确定了两种方法测定结果之间的函数关系。结果表明：该两种方法均具有较高的测定精度，且两种方法的测定结果很相近，热导法的略小于水银法的；两种方法熔敷金属扩散氢含量测定结果的线性回归方程为y=1.019 5x-0.189 8，与y=x非常接近。

According to GB/T 3965-2012, the diffusible hydrogen content in deposited metals were determined by mercury method and thermal conductivity method respectively. The determination results by the two methods were compared, and the functional relationship between the determination results by the two methods was determined by using mathematical statistics method. The results show that both the two methods had high determination precision with similar determination results, and the determination results measured by thermal conductivity method were slightly smaller than those measured by mercury method. The linear regression equation between the determination results of diffusible hydrogen content in deposited metals measured by the two methods was y=1.019 5x-0.189 8 which was very close to y=x.
