Modern high-performance aircraft has good maneuverability. The positive acceleration produced by aircraft can reach +9Gz, last for 15s to 45s, and always repeatedly occur.
现代高性能战斗机具有很高的机动性能,其在飞行中产生的正加速度可高达+gGz,持续时间可达15~45s,并可反复出现,已超出了人体正常的耐受限度。

速度增加的加速度为正加速度,速度减少的加速度为负加速度。
The acceleration is positive if the speed is increased, negative if speed is decreased.
然而,有关正加速度和噪声复合应激因素对脑的影响与防护措施尚未见研究报道。
However, effects of + Gz and noise combined stress on pilots have not been reported yet.
现代高性能战斗机产生的高g值持续性正加速度可导致脑缺血、缺氧,继而引起脑功能障碍。
High sustained + Gz acceleration produced by modern high performance aircrafts can induce brain damage because of ischemia and hypoxia.
Then you guys know, you just told me, acceleration is -9.8, We call it "minus" because it's accelerating down and up was taken to be the positive direction.
然后你们都知道,你告诉我,加速度是-9.8,我们取负号是因为加速度方向朝下,而正方向为竖直向上
