目的探讨大覆盖面抗荷服所应采用的抗荷调压器压力制度。方法４名男性受试者参加了离心机试验，增长率为３Ｇ／ｓ、峰＋ＧＺ作用１０ｓ～１５ｓ。先测定受试者基础Ｇ耐力，然后测定穿ＧＺ－２大覆盖面抗荷服、分别以１０．０ｋＰａ／Ｇ、１１．３ｋＰａ／Ｇ及１２．７ｋＰａ／Ｇ三种压力制度充气时的Ｇ耐力，并对腹、大腿、小腿及足部的受压程度进行主观评价。结果上述三种压力制度充气所提高的Ｇ耐力分别为３．１３Ｇ、３．５９Ｇ和３．９０Ｇ（Ｐ＜０．０１）。＋ＧＺ暴露时的平均心率随压力制度的增加而显著下降（Ｐ＜０．０５）。各部受压程度的主观感觉以腹部为最大，但均可耐受。扎弹性腰带后腹部受压程度评分显著下降（Ｐ＜０．０１）。结论在扎弹性腰带条件下，对ＧＺ－２抗荷服采用１１．３ｋＰａ／Ｇ的压力制度是可行的。
Objective To investigate the anti-load regulator pressure system that should be used in large coverage anti-service suits. Methods Four male subjects participated in the centrifuge test with a growth rate of 3G / s and peak + GZ for 10s to 15s. G basement endurance was measured first, and then measured G G-2 large coverage anti-service, respectively, with 10.0kPa / G, 11.3kPa / G and 12.7kPa / Subjective assessment of the degree of compression of the abdomen, thighs, calves and feet. Results The G-endurance of the three inflation systems increased by 3.13G, 3.59G and 3.90G, respectively (P <0.01). The average heart rate at + GZ exposure decreased significantly with increasing pressure regime (P <0.05). The subjective perception of the degree of compression by the departments of the abdomen is the largest, but they are both tolerable. Tie elastic belt posterior abdomen compression degree significantly decreased (P <0.01). Conclusion Under the condition of tie elastic belt, it is feasible to adopt the pressure system of 11.3 kPa / G for GZ-2 anti-g clothing.
