然而，实际情况不能不考虑回取速度。

However, the return speed must be considered in realistic condition.

如浸取矿金的体系也处非平衡状态，则不但浸取速度快，而且硫脲消耗少。

If the leaching system of ore gold is in the nonequilibrium state, it possesses not only higher leach rate but also less consumption of thiourea.

您可以通过独特的预取机制大幅度提高速度，通过静默加载和缓存所浏览页面上的所有链接，这种机制能够重新利用空闲带宽。

You can increase speed dynamically with the unique pre-fetching mechanism, which recycles idle bandwidth by silently loading and caching all of the links on the page you are browsing.

It's useful to have the average acceleration, which you can find by taking similar differences of velocities.

平均加速度也是很有用的,你可以用类似方法,取速度的变化量求出来

In that limit, we can measure velocity right now.

取极限的话,我们可以马上测出速度

So, the average is found by taking two instants in time, say t1 and later t2, and you find out where it was at t2 minus where it was at t1 and divide by the time.

平均速度就是取两个时刻,比如t1和之后的t2,用t2时刻的位移,减去t1时刻的位移,再除以这段时间
