摘　　要：目的探讨一种新型综合防护服的抗荷性能。方法在载人离心机上分别测定5名受试者的基础+Gz耐力和采用新型综合防护服时的+Gz耐力,采用+Gz加速度的增长率都是6 G/s,峰值作用持续时间为15 s,在加速度作用期间,嘱受试者呼吸不能用力,亦不能收紧全身肌肉。结果受试者采用综合防护服的+Gz耐力为(5.85±0.22)G,显著高于基础+Gz耐力(P<0.01),综合防护服的抗荷性能为(2.55±0.11)G。结论新型综合防护服能实现对快增长率加速度实现有效防护。Objective To investigate the ＋Gz protection capacity provided by a new type of integrated protective suit.Methods ＋Gz tolerance of five subjects was measured through centrifuge exposures while unprotected or protected by an integrated protective suit respectively. The centrifuge exposures were sustained acceleration with an onset rate of 6 G/s.During each exposure, the subjects were required to breathe in the manner of HP maneuver without stressing any muscle.Results When the subjects were wearing the integrated protective suit, the ＋Gz tolerance was up to（5.85±0.22）G, significantly higher than basic ＋Gz endurance （P〈0.01）. ＋Gz protection capacity of the integrated protective suit was（2.55±0.11）G（P〈0.01）. Conclusion The new type of integrated protective suit can provide effective protection for rapid onset rate acceleration.
