对三种不同扩大囊覆盖面积（ＥＢＣ）的抗荷服性能在离心机上进行了评价，并与标准的（Ｓｔｄ）ＫＨ─３型五囊式抗荷服及全覆盖侧管式（ＦＣＣ）抗荷服进行了对照。Ｓｔｄ和三种ＥＢＣ抗荷服的囊分别约覆盖脐以下下体的３０％、４３％、６５％和９０％。在快增长率（３Ｇ／ｓ）的离心机＋Ｇｚ暴露时，测定了５名被试者着这些抗荷服的松弛＋Ｇｚ耐力。Ｓｔｄ、ＥＢＣ（４３％、６５％和９０％）及ＦＣＣ抗荷服提高的＋Ｇｚ耐力分别为１．４５，２．１３，２．８０，３．６０和１．８５Ｇ，在＋５Ｇｚ（抗荷服充气）暴露时，着ＥＢＣ（６５％和９０％）抗荷服的被试者心率显著低于着Ｓｔｄ抗荷服（Ｐ＜０．０１）。以上结果表明，ＥＢＣ抗荷服比Ｓｔｄ抗荷服能显著提高＋Ｇｚ耐力并降低心率。
The load-bearing performance of three different EBC was evaluated on a centrifuge and compared with the standard (Std) KH-3 five-cell anti-Dutch suit and full coverage side-by-side Dutch clothes were compared. The cysts of Std and three EBC anti-sufferers cover approximately 30%, 43%, 65% and 90% of the lower umbilicus, respectively. Five subjects were tested for relaxation + Gz endurance in these anti-clothing suits at rapid G3 / s + Centrifuge + Gz exposures. The + Gz endurance of Std, EBC (43%, 65% and 90%) and FCC anti-dutch clothing were 1.45, 2.13, 2.80, 3.60 and 1.85G, respectively. Inflatable) exposed subjects, the heart rate was significantly lower in patients with EBC (65% and 90%) than in those with Std (P <0.01). The above results show that, EBC anti-Dutch clothing than Std anti-Dutch clothing can significantly increase the + Gz endurance and reduce heart rate.
