The repetition of the ultrasonic sound and the experiment of zero velocity in gas flowmeter are tested using this speed measurement system.
利用该测速系统,进行了超声波的重复性测试,以及在以空气为介质的零流实验。
Clearly, here the velocity is zero.
显然,这里的速度就是。
The angular velocity is zero when you release it and is a maximum when it goes through the lowest point.
角速度是,当你释放它的时候,当它到达最低点,速度达到最大。
Let's plot droplet velocity as a function of looking at the number that have this velocity 0 with the zero being in the center here.
我们将液滴的速度设定为,观察那些数字作用,在中心的地方,速度为。
So, hopefully that kind of clears up that question. And, of course, when the velocity actually is zero, this equation that the de Broglie has put forth is valid for anything that has momentum, so if something does not have any velocity at all, it actually does not have momentum, so you can't apply that equation anyway.
能回答你的问题,当然,如果速度真的是零的话,德布罗意提出的这个方程,只对有动量的物体成立,所以如果一个东西没有速度,它没有动量,也就不能应用这个方程。
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
