The slant of the roof is too steep to climb.

屋顶斜太陡无法攀爬。

And a sloper is like a very sloping hold.

斜一个非常倾斜着力点。

But this line and this line are parallel.

斜这条线可以看成截线。

The last stage is honing and putting a very fine edge or bevel.

最后一步用磨刀石磨，继而得到光滑边缘或斜。

A few days later, I was moving forward over a slope that seemed safe when suddenly, without warning, my world dropped out from under my skis.

几天以后，我滑过一个看似安全斜坡结果毫无警告，我雪橇下大地突然不见了。

Can the avalanche be traced back to a single bevel, rolling down the mountain, slowly pushing into motion increasingly bigger rocks that we just didn't notice until the ever-escalating movement became big enough to see?

雪崩否可以追溯到一个单一斜，从山上滚下来，慢慢地推动来大岩石运动，直到不断升级运动变得足够大，我们才注意到？

An inclined plane can be pretty much any object — a ramp, a slide, or even just a block of wood — as long as it consists of a sloping surface.

斜几乎可以任何物体——斜坡、滑梯，甚至只一块木头——只要它由一个倾斜表组成。

No misunderstanding. I've learned what that request actually means, and I don't want to be joined to another object by an inclined plane wrapped helically around an axis.

我没误会 我了解到那个要求意味着什么 我不想变成一个斜绕轴螺旋状转上几圈之后样子。

The scientists used high-speed video cameras to record the position of the snakes as they moved sideways up different inclines.

科学家使用高速摄像机记录蛇在不同斜上升置，这种运动叫蛇形。

But thanks to our skillful coxswain, we were fouled on the bias rather than broadside, so we didn't capsize.

这水必须排出去。由于艇长机灵，艇身只斜而不正受到海马攻击，所以没被憧翻沉没。

The function of pyramids changes between groups and cultures, and often they will be stepped rather than flat-sided.

金字塔功能因群体和文化不同而不同，它们通常阶梯式，而不有着平滑斜。

This kind of tear right here is a beveled or a scarf tear.

这种撕裂斜或围巾撕裂。

If you were to measure this angle right over here, you would get theta.

这里已知斜同水平夹角θ 未来视频中 我们会明确这个角为30度 45度等等。

Like inclined planes, pulleys are used to gain a mechanical advantage: objects are easier to lift using a pulley system than by using your own two hands.

和斜一样，使用滑轮为了获得机械优势：使用滑轮系统比使用你自己双手更容易举起物体。

It wouldn't be surprising if, when you heard the word pyramid, you thought of the spectacular flat-sided Pyramids of Giza at Egypt.

当你听到金字塔这个词，你会想到有着平滑斜吉萨金字塔群，这并不奇怪。

So generally, Japanese sushi knives, called yanagi, designed to be a little bit thinner behind the blade, and has the bevel, which is much more elongated to kind of create a thinner blade and make it easier to slide through.

所以一般来说，我们称之为柳日本寿司刀被设计成在刀片后更薄一点，并且有一个更细长斜，以形成更薄刀片，更容易滑过。

Helpful when you're trying to lift heavy objects, the inclined plane offers a mechanical advantage: the force required to move an object up the incline is less than the weight being lifted.

当你想要举起重物，斜可以提供机械优势：将物体沿斜向上推所需力小于直接举起物体重量。

We know the component of gravity that is perpendicular to the plane-- we figured out this two videos ago-- is 49 square roots of 3 newtons.

垂直于斜重力分量 两节视频前我求过 等于49倍根号3牛。

And the first flat-sided pyramid was completed in the fourth dynasty under the reign of Sneferu, called the Red pyramid.
