常見例句

In this paper, the tangent vector loading method and the boundary element restrain method was presented.
采用了切線矢量加載和邊界單元的約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，可以用微分關系,或受約束的偏微分來表示,曲線的切向量，就是這樣了。
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.
正如在曲線的情形中那樣做出的選擇,那是當沿著曲線行進時,可以用繞著切向量,順時針旋轉來規(guī)定正向。
