这个程序非常基本——它计算在给定速度(单位为每小时英里数)和时间(单位为小时)情况下的旅行距离。

The program will be very elementary — it will calculate the distance travelled given a speed in miles-per-hour and a time in hours. Here is the code for the ppe (enter as ppe_distance.c).

通过MATLAB仿真看出，使用该控制算法可以很好地实现跟踪给定速度，使流体类负载有很好的稳定性能。

Through the MATLAB simulation, it is proved that this control algorithm can realize tracking to the assigned speed and enable the fluid class load to have very good stable performance.

第2部分给出了工作负载调节方法的实现细节，您可以使用此方法来限制消息被传播到给定端点系统的速度。

Part 2 presents the implementation details of a workload throttling approach that you can use to impose a limit on the rate at which messages are propagated to a given endpoint system.

What that means is, if you know the velocity of the given time and you know the initial velocity, you know what time it is.

这个方程的意义是,如果你知道某个给定时刻的速度,并且知道初速度,你就能知道运动的时间

But before you even do that, I want to define for you an important concept, which is the velocity at a given time, v .

但在这之前,我要给你们定义一个重要的概念,也就是给定时刻的瞬时速度v

If you want to know how fast it's moving at a given time, if you want to know the velocity, I just take the derivative of this answer, which is 10-10t.

如果你想知道它在给定时刻的运动有多快,如果你想知道它的速度,我只要对这个式子求导,得到10-10t
