样条小波和正交小波是两种应用广泛的小波方法。本文比较了这两种方法的算法、性能以及在分析化学信号处理中的应用效果。研究表明，样条小波比正交小波更适合于高噪声信号的处理。样条小波比正交小波得到的曲线更接近理论曲线，误差也比正交小波小。
Spline wavelet and orthogonal wavelet are two widely used wavelet methods. In this paper, comparison of these two methods has been made, including their algorithm, properties and results of signal processing in analytical chemistry signals. It is found that spline wavelet is more effective than orthogonal wavelet in processing high noise signals. The curves obtained from spline wavelet are closer to the theoretical ones than those obtained from orthogonal wavelet and the errors of spline wavelet are smaller than those of orthogonal wavelet.
