介绍了生物活性多肽定量构效关系（QSAR）中化学结构描述符和建立数学模型统计方法的研究概况。
This paper introduced the study general situation of the chemical structure descriptors and statistical method of mathematical modeling in bioactivity polypeptide QSAR research.
建立定量构效关系模型第一步是计算大量的分子描述符，下一步则是对这些描述符进行变量选择。
The first step in building a QSAR model is to calculate a great number of molecular descriptors, then the second is to select the descriptors most correlated to the studied object.
