目的盐碘定量检测的计算工作繁琐,介绍一种简捷的程序运算方法。方法使用CASIO?χ-3600 P计算器,利用X、K、M寄存器输入程序变量,P1区程序求出样品碘离子含量,转换在SD状态,读取均数和标准差,P2区程序求出RSD%、QU、QL。结果发掘了该类计算器的潜在功能,完成了全部公式的计算,在盐碘定量检测的计算工作中,计算器得到了合理、正确的使用。结论在程序存储器外输入变量进行程序运算的方法,改变了传统的程序工作模式,突破了程序存储器38步容量的限制,程序区间键与暂停键组合,形成了一种不需要条件检验的循环运算体系,适用于小样本资料的程序运算,编程简单、操作方便、快速、准确。
Purposes Salt iodine quantitative calculation of cumbersome work, introduced a simple method of calculation procedures. Methods The CASIO χ-3600P calculator was used to input the program variables using the X, K, and M registers. The P1 program was used to determine the iodide content in the sample. The conversion was performed in the SD state, the average read, and the standard deviation. RSD%, QU, QL. Results The potential functions of this kind of calculator were explored and the calculation of all the formulas was completed. The calculator was used reasonably and correctly in the calculation of salt iodine quantitative detection. Conclusion The method of inputting variables outside the program memory for program operation changes the traditional program operation mode, breaks through the limitation of the program memory capacity of 38 steps, and the combination of the program section key and the pause key forms a loop operation that does not require condition checking System, suitable for small sample data program operation, programming is simple, easy to operate, fast and accurate.
