摘要
通过对病毒基因序列的遗传距离(K)的演算,发现公式中的p和q应理解为转换率和颠换率;计算所得的K值是一个百分率,更适合于显示生物进化的时间概念。因此建议将遗传距离改名为进化率。并从进化率计算中的规律性变化,探索了病毒进化的信息。
In the course of calculation of genetic distance of virus gene, p and q should be comprehended of the transition rate and transversion rate. The result K should response the time concept of evolution speed if K would be a percent. So genetic distance were proposed to change into evolution per cent, then exploring expediently the trace of virus evolution from the disciplinary change of evolution rate.
