基本向量 meaning in English

basicvector
basis vector
fundamental vector

On the relationship between the fundamental vectors of two curves in space
空间两曲线的基本向量之间关系研究
Considered the relationship between the dirac structures of poisson - nijenhuis manifold and the basic vector field , we proof that the basic vector field can keep the dirac structures of poisson - nijenhuis manifold which discussed before
考虑了基本向量场与dirac结构的关系，在前三节的基础上证明了基本向量场可以保持上述李双代数胚上的dirac结构。
The last , we study the properties of the basic vector field and 1 - form in the poisson - nijenhuis manifold , making a systematic organization of these contents and giving some appropriate adds . therefore , we unified with the conclusion of the poisson vector field on poisson manifold in reform
最后我们研究了poisson - nijenhuis流形上基本向量场和基本1 -形式，对已有的成果进行了系统的整理，并加以补充。由此将poisson - nijenhuis流形上基本向量场和泊松流形上的泊松向量场从形式上得到了统一。
