• 现在我们拿这个向量向上圆盘

    Now take your disk with its normal vector sticking up.

  • 每一个平面无数条向量

    Any plane actually has infinitely many normal vectors.

    youdao

  • 通常不是一个单位向量

    And that is, in general, not a unit normal vector.

    youdao

  • 现在单位向量乘以那个

    Now, let's multiply that by the unit normal vector.

    youdao

  • 那么当然知道它的向量

    Well, you know the normal vector.

    youdao

  • 从而法向量的方向竖直向上向下的。

    The normal vector is just sticking straight up or straight down.

    youdao

  • 曲面相同向量

    All right, it has the same normal vector as the surface.

    youdao

  • 那么向量又是什么呢?

    What is the normal vector?

    youdao

  • 可以曲面上任意长度向量

    It can be a normal vector of any length you want to the surfaces.

    youdao

  • N长度相同法向量只是符号不定。

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

    youdao

  • 向量就是梯度向量

    The normal vector will just be the gradient.

    youdao

  • 比方打算向量指向向上

    Let's say that I am going to do it with the normal pointing upwards.

    youdao

  • 来再次解释一下如何得出这个圆柱面向量

    Let me re-explain quickly how I got a normal vector for the cylinder.

    youdao

  • 第一单元得叉积、向量这些,现在有用了。

    The first unit about cross-products,normal vectors and so on is actually useful now.

    youdao

  • 向量方向上,分量零。

    The normal component is zero.

  • 文章讨论支持向量基础追踪去杂之间关系

    This is the paper in which the relation between SVM and BPD is studied.

    youdao

  • 基于复数向量表示,建立了机构的运动学模型

    The kinematic model is first studied using the vector theory.
