结果：所建立的指纹图谱分析方法的方法学考察符合规定标准，确定了10个共有峰；该方法能很好的鉴别不同产地虫草及虫草菌丝体。

The method enhances peak values of fingerprint samples by convoluting with a constant mask and therefore suppresses the noise. It restores the structure of fingerprint ridges and valleys better and improves the precision of the fingerprint ridge frequency, which is propitious to the subsequent processing in the fingerprint recognition system.

该方法通过给定的模板对指纹采样信号卷积，增强了信号峰值，抑制了噪声，从而还原出指纹的脊谷结构，提高了指纹脊频率估计的精确性，有利于指纹识别时的其他后续操作。
