摘　　要：提出了一个计算带有厚吸收片的ＰＩＮ中子探头灵敏度的方法，即分层分块蒙特卡罗模拟联合模型（ＬＰＭＣ）。根据计算过程．用ＦＯＲＴＲＡＮ７７语言编写了计算程序ＬＰＭＣ，其计算方法本身的误差不大于１．８８％。ＬＰＭＣ计算结果与实验值在相对误差范围内符合，解决了仅用ＬＰ理论对带有厚吸收片的ＰＩＮ中子探头灵敏度计算结果与实验偏差过大的问题．A method of calculating sensitivity of PIN neutron detector system with a thick absorber, that is, the model of Layers and Pieces with Monte-Carlo (LPMC)simulation has been put forward. The program LPMC was written in FORTRAN 77language. The error of the calculation is not more than 1.88%. The results from LPMC calculation are in agreement with the experiments within the above error,thus the shortcoming of over-deviations for the LP calculation has been avoided.
