摘　　要：本软件利用高斯函数的正态分布特性对XRF标准谱进行数字脉冲模拟和D/D转换。模拟生成的XRF谱与仪器实际谱进行峰型对比,即将两幅图作一定比例的缩放后叠加,计算相对最大和最小漂移距离以此确定XRF谱与仪器的情况,值差越小表明仪器精度越高。A software is being developed to allow convenient and accurate determination of the X-ray fluorescence （XRF） spectrum. It uses the features of Gaussian to calculate an ideal spectrum by simulating digital pulse and making the D/D conversion. Peak shapes of the simulated XRF spectrum and measured spectrum are compared. By zooming two images and making them superposition, the relative maximum and minimum changes in the peak position are calculated. The smaller the change is, the higher the instrument accuracy is.
