如何从流沙中逃生

小蛮蛮

When walking in quicksand country, carry
a stout pole—it will help you get out should
you need to.

As soon as you start to sink, lay the pole on the
surface of the quicksand.

Flop onto your back on top of the pole.
After a minute or two, equilibrium in the quicksand
will be achieved, and you will no longer sink.

Work the pole to a new position: under your hips
and at right angles to your spine.

The pole will keep your hips from sinking, as you
(slowly) pull out first one leg and then the other.
Take the shortest route to firmer ground,
moving slowly.

How TO AVOID SINKING
Quicksand is just ordinary sand mixed with upwelling
water, which makes it behave like a liquid. However,
quicksand—unlike water—does not easily let go. If
you try to pull a limb out of quicksand, you have
to work against the vacuum left behind. Here are a
few tips:

•The viscosity of quicksand increases withshearing—move slowly so the viscosity is as lowas possible.
• Floating on quicksand is relatively easy and isthe best way to avoid its clutches. You are morebuoyant in quicksand than you are in water.Humans are less dense than freshwater, andsaltwater is slightly more dense. Floating is easierin saltwater than freshwater and much easier inquicksand. Spread your arms and legs far apartand try to float on your back.
When in an area with quicksand, bring a stout poleand use it to put your back into a floating position
Place the pole at a right angle from your spineto keep your hips afloat.

1. 当在有流沙的地方行走时，记得带一根结实的木棍——它将帮助你摆脱流沙。这是你应该做的。
2. 一旦你开始下沉。就将木棍放在流沙表面。。
3.  小心地将木棍穿过背部。一两分钟后身体会和流沙实现力的平衡，你将不会继续下沉。
4. 将木棍移到一个新位置：木棍和你的脊椎成直角。这时缓慢拉出你的一只脚后再缓慢拉出另一只脚。木棍将保持使你的臀部不再下沉。
5. 缓慢移动身体，以最短的路线离开流沙移动到结实的地面。

怎样避免下沉？
流沙只是普通的沙上涌的水混而这合成的。这使得它更像一种液体。然而，流沙不像水那样让你能轻易的摆脱。如果你想尝试将你的肢体从流沙中拉出来。那么你就要抵抗流沙产生的负压。
下面是一些比较有用的小贴士：
1. 流沙的粘度随着不断运动而增加——身体缓慢的移动会尽可能的减少流沙的粘度。

2. 漂浮在流沙上面是很容易的而且这是逃脱流沙的最好方法。你在流沙中的浮力比你在水中的浮力大的多。人体的密度要小于淡水，而盐水的密度又比淡水的密度高一些。所以浮在盐水里比浮在淡水里面容易，浮在流沙里又比浮在盐水里来的容易。将四肢伸开，尽可能让你的背部浮在流沙上面。

1.  当你在有流沙的地方时，带一根短木棍，可以用它使你的背部浮在流沙上面。




2.  将木棍穿过腰部，保持你的臀部浮在流沙上面。
