按 Haldane 理论计算水下阶段减压潜水减压表时,步骤复杂。供查找理论组织氮饱和度的《检索表》精度也不高。尤其是理论组织的半饱和时间超出《检索表》范围和潜水作业中呼吸气体的氮浓度发生变化时,计算减压方案既繁琐复杂又耗时较长。随着电子计算器的普及,特别是可编程序计算器的出现,计算的精度和速度有很大的提高,我们使用 CASIO FX—702P 计算 According to the Haldane theory to calculate the underwater stage decompression diving decompression table, the steps are complicated. The accuracy of the “search table” for finding the nitrogen saturation of the theoretical organization is not high. In particular, when the theoretical organization’s half-saturation time is outside the range of the “look-up table” and the nitrogen concentration of respiratory gases in diving operations changes, the decompression scheme is both cumbersome and time-consuming. With the popularization of electronic calculators, especially the advent of programmable calculators, the precision and speed of computation have greatly improved. We use CASIO FX-702P to calculate
