摘　　要：根据遗传程序设计原理和方法,利用Lennard-Jones(12-6)模型所提供的碰撞积分ΩV与量纲一温度T*的数据,推导出了碰撞积分的关联式。利用该关联式,采用QBASIC语言编写程序,计算了82组碰撞积分数据,总平均相对偏差为0.0816%。计算准确度优于Neufeld关系式。文中关联式的高度准确性证明遗传程序设计是一种新的可靠的编程应用计算技术,文中关联式为碰撞积分的计算提供了准确度更高且便于计算机计算的方法。Based on the principle and method of genetic programming and using the data of collision integral Ωv and dimension one temperature T^＊ in Lennard-Jones（12-6） model, a new model for collision integral was proposed. By using QBASIC programming the correlation equation was used to calculate 82 groups of collision integral, with the overall average relative deviation of 0. 081 6%. The correlation result is more accurate than that of Neufeld. The satisfactory accuracy of the correlation proves that the genetic programming is an advanced and reliable programming application computing technology, thus providing a more accurate and convenient computation method for collision integral computation.
