We estimated the time at which the rate of decline begins to accelerate (the change point), and the pre - and post-acceleration rates of decline, from the longitudinal data using a change point model.
利用改变点模型从纵向数据中找出加速点、前加速期下降速率和后加速期下降速率。
With the remarkable acceleration of the railway, the pre emitting codes technique within the station on coded track circuit is widely applied as a basic technical equipment for train safety.
随着铁路几次大的提速，站内电码化预发码技术作为保证行车安全的基础设备已被广泛采用。
It is shown that when the radius of the electron is greater than a critical length, the behavior of the solution is fine, no run-away and pre-acceleration appears.
结果表明当电子半径大于一个临界长度时，方程的解表现出良好的性质，不会出现奔离和预加速的现象。
Auto-Start function (ATS):A pre-set throttle position, less than full throttle, to be used for the initial acceleration off the line without having wheel spin.
自动启动功能（ATS）：预置一个油门位置（油门不要打满）以用于初始加速，不上线而车轮处于停转状态。
