摘要: 建立了一个简便、可靠的扫描质子探针元素分布图本底值剔除方法，编制了逐点本底计数值剔除计算程序。结合实际地质样品的扫描质子探针元素分布成图，对方法的有效性做了对比实验。结果表明，与传统的成图方法相比，新方法具有图像清晰、真实的优点。同时讨论了方法的误差和误差的减小途径。Abstract: A simple and reliable method for the correction has been developed.A program was prepared for the background correction on a point-to-point basis.An elemental map is described which demonstrates that compared with traditional procedures,the present method
