如果你的马已经学会如何啃咬快松结来解放自己，你一定要把多余的绳子部分穿过绳圈来达到“马防”的作用。

If your horse has learned how to nibble the quick-release knot and free himself, you will have to "horse-proof" the knot by dropping the tail of the rope through the loop as shown here.

如果你觉得有必要，请在拴所有的马时使用快松结，这样的结可以在你拉拽绳子的一端时马上松开被拴住的马。

Tie all horses with a quick-release knot so if you need to, you can instantly pull the end of the rope and release the horse.

And what we find out is the wavelength of a Matsuzaka fastball is 1.1 times 10 to the -31 meters.

我们算出松阪快球的波长,是1，1乘以10的负31次方米。

For example, if we're talking about a pitcher, like Matsuzaka, we might want to know the speed of his average fastball.

举例来说，如果我们谈到一个投手，就像松阪，我们想知道他投出,快球的平均速度。

So, if we're trying to figure out the wavelength of a Matsuzaka fastball, we need to consider the velocity first, which is 42 miles per hour.

如果我们尝试计算一个,松阪发出快球的波长，我们首先需要考虑速度，每小时为42英里。
