摘　　要：薄膜材料在包装等行业的广泛应用,极大推动了其在各种环境下气体透过性能的研究.为求出在非标准环境下的透气量,提出了一种数据拟合的方法,该方法基于最小二乘法原则,采用matlab和vc混合编程,充分利用了两种工具的优点.With the rapid growth of application of film material in packing industry, the study on gas permeable ability in different kinds of condition is effectively pushed. In order to figure out the performance of gas permeability in nonstandard temperature, this paper introduces a new method of data fitting. It is based on least-square principle and matlab and visual c＋＋ is used to mix programming, so that it can make good use of the two tools. The data fitting platform can perform widely, and it brings a valuable reference to permeability test and packing material choose in packing industry.
