本文介绍了用FORTRAN语言编写的适用于小型电子计算机的电子探针数据处理和ZAF(原子序数、吸收和荧光效应)修正的电子计算机程序.处理程序把MS-46电子探针输出的原始数据进行死时间和背景修正,得到强度比K,修正程序则把强度比K进行ZAF修正得到真实成分.程序只需输入分析元素的化学符号、所用的线系和操作电压.除原子量外所有的常数,如临界激发电压、特征X射线波长和质量吸收系数等都是在程序内计算的.讨论了编制数据处理和修正程序应注意的问题,给出了程序框图,并用已知含量的强度比验证了修正程序.本程序可处理从原子序数5(B)到92(U)的所有元素.

A data handling and correcting program adaptable to a minicomputer(16k mem-ory) for use in quantitative lectron icroprobe analysis was written in FOR-TRAN. The program is applicable to all elements in the atomic number range from5(B) o 92(U) and has the capability to deal with 12 elements and 30 measuringpoints each time. The data handling sub-program llows the time and number ofmeasurements for each analysing point to be varied at will and gives the averageintensity atios K as the output. The correcting sub-program allows the correctionof atomic number, absorption and fluorescence ffects and can handle various el-ements at different accelerating voltages. All physical constants, except atomicweights hich are stored in the memory, are calculated in the program, so thatonly few input data are needed.
