In this paper, the inverse transform of the operator for the irrotational field is analyzed by taking L vector wave functions as basis functions and weight functions for the moment method.
分析了用Ｌ类矢量波函数作矩量法中的基函数和权函数时无旋场算子的反演，并将得到的并矢格林函数表达式与算子规范下的从求解标量Ｐｏｉｓｓｏｎ方程得到的相应表达式作了比较。
Based on non-linear innovation model,the "triple helix field" and "triple helix circulation" concepts are proposed to stimulate further the theoretic exploration on triple helix.
