basic reproduction rate

基本解释

This means the observed threshold rate is unlike an infectious disease's basic reproduction number.
这意味着观察到的阈值率跟一种流行病的基本传染数（见注释1）不同。
It is necessary to drop the infection efficiency by over 85% through protection measures for reducing the basic reproduction rate below the critical level.
防护措施必须使感染效率下降85 %以上，才能使医院内传播的基本繁殖率降至临界值以下。
Under the guidance of basic reproduction number, the negative effect can be alleviated and worms can be terminated by introducing a anti-virus system of high initial installation rate.
在基本再生数的指导下，通过提高防病毒系统预装率，能减弱机器更新带来的负面影响，并能有效抑制蠕虫的传播。
