12～60m空气潜水减压表的模拟潜水实验观察

本表深度12～60m,共178个减压方案。采用5～120min共13类理论组织,根据潜水深度及水底停留时间选取不同的氮过饱和安全系数,按Haldane原理,经计算机计算。并经17个深度、44个方案共141人次的模拟潜水验证,无减压病发生,各生理指标无异常改变。与原表相比,本表在理论组织分类及安全系数的选取等许多方面作了较大改进。

The Experimental Evaluation of the Underwater Stage Air-decompression Table for Divers to Depths Between 12 to 60 m

The air dive decompressiom table applicable to the depth ranging from 12 to 60 m consisted of 178 depth-time profiles with an increment of 3m. Based on the HaldaneZs theory, the table was calculated with the computer by applying 13 half-time tissues(5-120 min)and various coefficient of safe supersaturation in accordance with different dive depths and bottom times. 141 man-time simulated dives were conducted to 17 different depths and decompression were completed on 44 schedules. No DCS occuredand all the physiological parameters tested were within normal range. When compared with the table issued by our Navy, the present table showed much improvement in the choice of the half-time tissues and coefficient of safe supersaturation.Therefore it is safer and more practical than the existing table.
