英汉例句

• if you imagine that you have this big cylindrical type in front of you, hopefully you can see that a normal vector is going to always be horizontal.

  想象一下,你的面前有一个大圆柱，希望大家可以想象到,其法向量总是水平的。

• you can remember, if it helps you, that if a surface is to your right then the normal vector will go down.

  你也可以这样记，如果曲面在你的右边,那么法向量就向下。

• in fact, i get my normal vector 1/a by scaling this guy down by a factor of a.

  事实上，上面这个过程就是,把法向量的长度缩减到原来的。

• and let「s say i want to orient my cylinder so that the normal vector sticks out.

  我给这个圆柱确定了方向,即法向量指向圆柱之外。

• another way to do it, of course, would provide actually parametric equations of these lines, get vectors along them and then take the cross-product to get the normal vector to the plane.

  当然也有另一种方法，就是用参数方程表示这两条直线，用两条直线的方向向量作外积,从而得到切平面的法向量。

• and so the normal vector is going towards what is up for me.

  所以法向量指向我的上方。

• the normal vector will just be the gradient.

  法向量就是梯度向量。

• my normal vector would be maybe somewhere here.

  法向量可能这里某个位置。

• namely, we will be saying the /a normal vector is x, y, z over a, plus or minus depending on whether we want it pointing in or out.

  我们容易知道,法向量为，正负号取决于它是指向外面还是里面。

• well, if you followed what we」ve done there, you know that the normal vector compatible with this choice for the curve c is the one that points up.

  如果一步一步的把该做的都做了，你会知道，与c相容的法向量,是向上的。

• ok, and that「s going to be the normal vector to the surface or to the tangent plane.

  这就是切平面的,或者说这个曲面的法向量。

• if you know what a cylinder looks like, you probably can see that the normal vector sticks straight out of it horizontally.

  如果大家知道圆柱面是什么样的，那么就可以想象到,其法向量水平地指向外面。

• and we know how to find a normal vector to the level set, namely the gradient vector is always perpendicular to the level set.

  我们是知道如何去求水平集的法向量的，也就是垂直于水平集的法向量。

• this is a normal vector of the same length as n,well, up to sign.

  这是与n长度相同的法向量，只是符号不定。

• in particular, counterclockwise means that the normal vector will be going out of the region.

  逆时针旋转意味着,法向量是指向区域外的。

• now, if you wanted the unit normal vector to compute flux, then you would just scale this guy down to unit length, ok?

  如果想用单位法向量来计算通量，还得先把它标準化到单位长度？

• but, when it comes to looking for the normal vector, be rest assured that the normal vector to a horizontal plane is just vertical.

  但是在寻找法向量时,可以确定法向量与水平面垂直。

• ok, if we look at it near here, if we walk along this way, the surface is to our right .so, we should actually be flipping things upside down. the normal vector should be going down.

  我们看看这里，如果我们沿着这条路走，曲面就在我们的右边，我们应该是把它颠倒一下,这个法向量也应该向下。

• and, if you pay attention to the orientation conventions, you」ll see that you need to take it with normal vector pointing up.

  如果你注意到了方向的约定，你会发现它的法向量是向上的。

• when we know two vectors in a plane, it let us find the normal vector to the plane, and that is what we need to find the equation.

  当我们已知平面上的两个向量，我们就可以找到,这个平面的法向量，然后我们就可以用法向量来找到方程。

• and the convention is that the normal vector that i take goes to the right of the curve as i am traveling along the curve.

  惯例就是，法向量的方向就是,沿着前进的方向的右侧。

• one thing that「s on this picture that i haven」t drawn down is the normal vector to the plane.

  图上有个东东我没画,就是这个平面的法向量。

• so, for a sphere, the normal vector is divided by the radius of the sphere.

  关于球体，法向量是,除以球的半径。
