摘　　要：从样品成分设计、加工、均匀性检验到定值分析过程,遵循GB/T15000《标准样品工作导则》和YB/T 082《冶金产品分析用标准样品技术规范》的要求,研制了4个石灰石标准样品。标准样品氧化钙含量从42.62%~55.12%,二氧化硅含量从0.073%~7.97%,成宽的线性,其它多数成分也随着主成分的变化而相应有线性变化,涵盖了各种规格的石灰石品种。The requires for GB / T 15000 Directives for the work of reference materiapls and YB / T 082 Specification for CRMs for metallurgical product analysis were followed in the sample composition design,processing,homogenizing examination to the standard value analysis process. Four limestone standard samples were developed. The calcium oxide contents of standard samples were from 42. 62% to 55. 12%,the silicon dioxide contents were from 0. 073% to 7. 97%,they were wide linear,the most other components also varied linearly with the change of principal components,cover all kinds of varieties of limestone.
