tangent vector

常见例句

In this paper, the tangent vector loading method and the boundary element restrain method was presented.
采用了切线矢量加载和边界单元的约束方法建立分析模型。
Then actually there are ways you can use basically differentials and constrained partials to figure out what the tangent vector to the curve is and so on.
然后，可以用微分关系,或受约束的偏微分来表示,曲线的切向量，就是这样了。
In the case of curves, we made that choice by deciding that because we were going along some direction on the curve we could choose one side by saying let's rotate clockwise from the tangent vector.
正如在曲线的情形中那样做出的选择,那是当沿着曲线行进时,可以用绕着切向量,顺时针旋转来规定正向。
