Translation of unit vector from English into Chinese
Noun
mathematics
- In calculations, the unit vector indicates direction without magnitude.在计算中，单位向量表示没有大小的方向。
Examples of unit vector in a sentence
Engineers often use a unit vector in design.
Translations of "unit vector" in Context ordered by category and frequency
So, let me divide this by rho to get a unit vector.
除以p之后，就能得到单位向量。
It is not a unit vector.
它不是单位向量。
unit vector: Examples and translations in context
where dm is the mass at the point r, g is the acceleration of gravity, and k is a unit vector defining the vertical direction.
其中dm是在点r 的质量，g 是重力加速度，以及k 是定义垂直方向的单位向量。
A vector with magnitude of 1 is called a unit vector. They are also sometimes referred to as direction vectors or normals. Unit vectors are helpful when you need to keep track of a direction.
一个 大小 为 1 的向量称为 单位向量 。它们有时也被称为 方向向量 或 法线 。当您需要跟踪一个方向时，单位向量是有用的。
where σT is the transpose of the matrix of stress components and n is the unit vector normal to the surface (referred to the same system of axes as the stress components).
其中σT是应力分量矩阵的转置，n 是垂直于表面单位向量（指作为应力分量相同的轴系统）。
Planes clearly don't come out of nowhere, so they must be built. Constructing them in 2D is easy, this can be done from either a normal (unit vector) and a point, or from two points in space.
平面显然不是从哪儿冒出来的，所以必须构造。在2D中构造它们很简单，这可以从法线（单位向量）和点，或者用2维空间中的两个点来完成。
Cauchy's equation (Davis and Selvadurai 1996) relates the traction on a given surface to the stress state and a unit vector normal to the surface
Cauchy方程（Davis和Selvadurai 1996）是在一个给定的表面牵引应力状态和一个单位向量垂直于表面：
