文献半衰期是测度文献老化速度的一个重要指标，利用文献计量学和数理统计学的方法，对《工程力学》自1992年~2008年10月间的载文引文用三种半衰期的计算方法进行了计算，并且将结果和用插值法计算的结果进行了比较，计算结果表明：对《工程力学》而言，使用B-K方程计算的半衰期与插值法得到的结果最为接近。但是对超导专业期刊载文引文而言，新的半衰期计算公式得到的半衰期与插值法的结果最为接近。由此可见，在计算半衰期时，要选择最合适的公式进行计算。

Half-life of literature is one of important index to evaluate literature obsolescence, by using the theoretical methods of bibliometrics and mathematical statistic to calculate the half-life of the "Engineering Mechanics"from Jan 1992 to Oct 2008 as an example by three methods. The comparisons of results fitted by three methods were shown that the result of B-K equation was the closest to the results calculated by interpolation method. But for data of references in superconductor journals, the result of half-life calculated by new method was the closest to the results calculated by interpolation method. So we must choose the most suitable formula when we calculate half-life of literature.
