摘　　要：本文用长、短计数管补偿法消除端效应影响，并采用理想气体方程确定氚的质量，从而使氚水的放射性比活度的测量大大简化，精确度进一步改善。 compensation method with the long and short counters has been adopted to eliminate the terminal effect, and the ideal gas equation was utilized to determine the mass of tritium, thus the measurement of the specific activity of tritiated water is greatly simplified and the accuracy has been further improved.(
