摘要
为了探讨新型侧管式抗荷服（ＮＫＨ）、代偿服（ＮＤＣ）及抗调器（ＮＫＴ）的抗荷性能，对１０名被试者进行了体表压传递性能实验，并对９名被试者进行了离心机生理实验。结果表明，ＮＤＣ的大腿导压效率明显高于ＤＣ４代偿服（Ｐ＜０．０１），但ＮＫＨ的小腿导压效率明显低于ＫＨ４抗荷服（Ｐ＜０．０１）；ＮＫＨ的腹囊下体表压明显高于ＫＨ４抗荷服（Ｐ＜０．０１），而ＮＤＣ的腹囊下体表压明显低于ＤＣ４代偿服（Ｐ＜０．０１）；ＮＫＨ、ＮＤＣ配ＮＫＴ的抗荷效果分别为２．１５Ｇ和２．０５Ｇ，配ＫＴ７Ａ抗调器的抗荷效果分别为１．８５Ｇ和１．７５Ｇ，均高于ＫＨ４抗荷服、ＤＣ４代偿服配ＫＴ７Ａ抗调器的抗荷效果；ＮＫＨ、ＮＤＣ能明显降低Ｇ作用下的心率，增加心脏储备。
The purpose of this study was to investigate the +Gz protection afforded by new type capstan anti G suit (NKH),partial pressure suit(NDC)and anti G valve(NKT). 10 subjects underwent the transmit capacity test of body surface pressure, and 9 subjects underwent centrifuge physiological test. The results showed that pressure transmit effectiveness of the thigh with NDC was significantly(P<0.01) higher than that with DC 4 partial pressure suit(DC 4).And pressure transmit effectiveness of the calf with NKH was significantly(P<0.01) lower than that with KH 4 anti G suit(KH 4). The body surface pressure under abdomen bladder with NKH was significantly(P<0.01) higher than that with KH 4. And body surface pressure under abdomen bladder with NDC was significantly(P<0.01) higher than that with DC 4.The +Gz tolerances enhanced by NKH and NDC with NKT were 2.15 G and 2.05 G,respectively and that by NKH and NDC with KT 7A anti G valve(KT 7A)were 1.85G and 1.75 G,respectively.These figures were significantly higher than that by KH 4 and DC 4 with KT 7A. NKH and NDC can significantly reduce heart rate under +Gz exposure and improve heart reserve.
