C.I.P.W标准矿物计算方法的PC—1500袖珍计算机BASIC语言程序

BASIC LANGUAGE PROGRAMS FOR THE CALCULATION OF C.I.P.W NORMS ON THE PC-1500 POCKET CALCULATOR

摘要:

C.I.P.W标准矿物计算是火成岩岩石学研究中常做的工作。倘若手算,耗时费力,且难保一次性计算结果无误。为此,针对12种氧化物设计的,上机运行通过的BASIC语言程序可以换算20种基本标准矿物,适用于碱性、酸性、中性、基性和超基性岩类中火山岩及侵入岩的数十个岩石种属。计算和输出,一件样品约一分钟即可完成,且精度颇高。计算结果采用格式化输出,清晰醒目,易于查阅和使用。

Abstract:

The calculation of C. I. P. W norms is a common job in the petrological study of igneous rocks. Manual calculation takes more time and effort, and cannot guarantee the correct results by the calculation at once. Thus a BASIC Language program has been written particularly for converring twelve oxides into twenty standard minerals. The program has been run on the PC—1500calculator to be correct, and is applicable to the C. I. P. W norms cat culations for alkaline, acid, intermediate, basic and ultrabasic volc...
