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.

为什么松岛冰川融化得这么快呢？

Why is the Pine Island Glacier melting so quickly?

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。
