| 摘 要： | 对沃尔什函数的构造进行了深入系统的研究，改进了用瑞得麦彻函数构造连续沃尔什函数的公式，提出了离散沃尔什函数编号与哈达马矩阵行号(或列号)之间相互转换的一整套方法，理顺了离散沃尔什函数编号与哈达马矩阵行号(或列号)之间关系，使得用哈达马矩阵的行(或列)构造的离散沃尔什函数与连续沃尔什函数建立了统一对应的关系，从而可以通过抽样来实现用连续沃尔什函数构造离散沃尔什函数。

| Abstract: | A systematic and in -depth research on the construction of Walsh function are carried out. The formula of constructing continuous Walsh function with Rademacher function is improved. A complete set of mutually transforming methods between the numbers of the discrete Walsh function and the row or rank numbers of Hadamard matrix is brought up and their relationship is put in order, thus building up a unified and corresponding relationship between the discrete Walsh function which is made from the row or rank of Hadamard matrix and the continuous Walsh function and constructing the discrete Walsh function, with the way of sampling, by continuous Walsh function. |

| Keywords: | Walsh function Gray code Hadamard matrix progressive deriving method ( similar to cell division) |
