1982年12月4日在海军医学研究所的1201加压舱中,潜水员着装第二代25—Ⅱ型潜艇艇员单人水下脱险服的试制样机和28—Ⅱ型呼吸器,做从鱼雷发射管出艇的水下减压脱险实验。实验条件:发射管注水;注气加压245kPa(绝对压);加压速率49kPa/min。加压中受试者顾××逐渐感到耳鼓膜受压,于是习惯地用Valsalva氏法调压,结果受压感觉加剧,并产生疼痛。受试者又作第二次调压,此时疼痛几不可忍。于是用手按摩耳周围,试图减轻痛感。但
On December 4, 1982, at the Naval Medical Research Institute’s 1201 ballast tank, divers dressed in pilot prototypes and 28-II respirators for the second generation of 25-型 submarine crewmen in submarine escape suit, Launch tube out of the boat underwater decompression escapement experiment. Experimental conditions: launch tube water injection; injection pressure 245kPa (absolute pressure); pressure rate 49kPa / min. Subjects under pressure Gu × × gradually feel the tympanic membrane pressure, so accustomed to Valsalva’s method of pressure regulation, the result of increased pressure sensation, and produce pain. Subjects for the second time the pressure, when the pain is unbearable. So massage around the ear by hand, trying to reduce the pain. but
