- In order to observe the effect of the positive acceleration stress on the con-tents of both plasma and thalamus endothelin (ET),the acute exposure of+6Gz and +10Gz was carried out in 36 Wistar rats,and the exposure of + IGz used as control group. 为了观察不同正加速度(+Gz)负荷(即头脚向惯性力与重力相比的倍数)对血浆及丘脑内皮素(ET)含量的影响;我们对36只Wistar大鼠分别进行了+6Gz和+10Gz的急性暴露实验;并以+1Gz暴露为对照.
- When a swimmer slows and then finally applies forces there are stages of slowing down (the correct term is negative acceleration not deceleration) and speeding up (the correct term is positive acceleration not acceleration). 当游泳运动员慢下来然后增加力量以求得继续前进时会有不同的阶段，这就是减速阶段（正确用语是负加速度而非减速）和加速阶段（正确用语是正加速度而非加速）。
