The result demonstrated that the immune selective pressure only had selective function, but not the creating - mutation function in the mutation of virus.
本研究结果显示，抗体这一免疫压力在病毒的变异中可能只起选择性作用，而不起促进变异的作用。
Mutation frequency and selective efficiency in M2 were obviously increased by application of the technique.
应用这项技术，可大大提高M 2代突变频率和选择效率。
