需要声明的是,在上述表达式中,我用a表示跳楼者的最大加速度。 此外,我还假设跳楼者完全停下所经过的距离与整个下落距离相比可以忽略不计。
Just to be clear, I am putting the maximum acceleration in for a. Also, I have made the assumption that the stopping distance (s) is small compared to the jumping height.
这种学术加速度给人造成了一种印象,即任何超过几年时间长的科研成果都已经过时。
Because of the accelerated pace, the impression spreads that anything more than a few years old is obsolete.
但是,绝大部分的程序都需要经过允许才可以使用地点数据和照相机,使用加速度感应器却没这个要求。
But whereas most apps have to ask permission to access location data or the camera, that's not so for the accelerometer.
But I can add to this some number, like 96, that'll still have the property that if you take two derivatives, you're going to get the same acceleration.
但是我可以在后面加上某个数,比如96,经过两次求导你仍会得到,同样的加速度
