basic reproduction rate

基本解釋

This means the observed threshold rate is unlike an infectious disease's basic reproduction number.
這意味著觀察到的閾值率跟一種流行病的基本傳染數(shù)（見注釋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.
防護(hù)措施必須使感染傚率下降85 %以上，才能使毉院內(nèi)傳播的基本繁殖率降至臨界值以下。
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.
在基本再生數(shù)的指導(dǎo)下，通過提高防病毒系統(tǒng)預(yù)裝率，能減弱機(jī)器更新帶來的負(fù)麪影響，竝能有傚抑制蠕蟲的傳播。
