然后C有一个很小的二次方的上升，接着指数的上升直到你预期的饱和,那C约等于A0乘以1减,的负k2乘以时间次方，e，to，the，minus，k2，times，time。,速率常数k2长时间地起主导作用。

And then C has a very small quadratic rise, followed by the exponential rise to saturation that you'd expect. So C is approximately a0 times one minus e The rate constant k2 dominates the long times.

我现在在转换单位，最终得到以米为单位的结果，再乘以9。8米每二次方秒。

I'm just getting this into units that will give me, that will be in meters, times 9.8 meter per a second squared.

它们都有一个起点一个终点图中的蓝点，但二次方贝塞尔曲线只有一个红色控制点点而三次方贝塞尔曲线有两个。

A quadratic bezier curve has a start and an end point (blue dots) and just one control point (red dot) while a cubic bezier curve USES two control points.

Something raised to the second power has got to be positive.

二次方的东西,也一定是正数。
