摘　　要：对基于Laplace变换的大型正电子寿命解谱程序CONTIN（PALS2）的原理和使用作了简要说明，在实验基础上，对用CONTIN（PALS2）程序计算的结果进行了分析，并与用POSITRONFIT程序的结果进行了比较。The updated analysis program CONTIN(PALS2) based on the Laplace inversionof positron anniliilation spectra has been studied comprehensively. The principle andutilisation of the program have been explained exhaustively- Three auxiliaryprograms have been made to help the transportation of data and adjustment of thedata's pattern. Four experiments have been made, the results computed by programCoNTIN(PALS2) have been analyzed, and compared with those by POSIREONFITprogram
