To introduce perturbation corrections of lattice strain intosemiempirical MO calculations,we have written out the programs,STRAIN+SPHF,for calculating perturbation corrections of lattice strain,based onsemiempirical MO calculation program package MOPAC3.0.In principle,the theoretical method and program for calculating corrections of latticestrain can be employed for the studies of growth mechanisms for diamondfilms or other non-metallic films on any non-metallic heterogenic substrates.

运用引入晶格应变修正的AM1半经验分子轨道方法和不包含该修正的AM1方法，通过在Si(100)和(111)衬底表面上提取H原子以及CH3和C2H2吸附过程的计算比较研究，发现包含应变修正的结果比不包含该修正的结果更准确地描述了Si衬底上发生的化学反应过程，并且还能够揭示出无应变修正结果中没有揭示出的表面物理化学现象。
