It has changed from a minus sign to a plus sign because of this positive acceleration.
速度的符号已经，由负变正了，可是加速度又还是正的。
The short-term precursory anomaly is the "positive acceleration" phenomenon of water level.
它的短期震兆异常是水位变化的“正向加速”现象。
Here, when it makes this rounding curve the velocity is positive here, but on this side it's negative so what does that mean for the acceleration?
这里，就在曲线的拐角，速度一开始是正的，不过在另一边就成了负的，就加速度而言这又意味着什么呢？
There are also a number of factors that can negatively impact the effects of this acceleration; IP transparency for example, completely negates the positive benefits of HTTP multiplexing.
此外也有多种因素可能会对这种加速效果产生负面影响；举例来说，IP透明度会完全抵消HTTP多路复用的正面收益。
Acceleration: a change in velocity with respect to time. Values are either positive or negative with standard orientation.
加速度：速度相对时间的变化。加速度值根据确定的方向而为正或者负。
During phase 2, it was reported that there was a period of angular deceleration after the peak positive angular acceleration.
在第二阶段中，当肌电达到正峰值角加速度之后，还有一个角减速的过程。
