This paper presents not only a luothod to build an orthogonal wavelet basis of locality wcli but also a general mothod to build an orthogonal wavelet basis of all kinds of good quality. Its character: mother wavelet has concrete expression, better properties in smoothners and locality. This wavelet's order at which it converges to zero can reach to O(|t|-(3k+l), the k is arbitrary natural number. This method needn't rebuild function only if k is changed. This method can satisfiet all kinds of goals.
