observed threshold

基本解釋

Slow efficiency at threshold is observed to be nearly constant over the wide range.
在廣域范圍內(nèi)觀測到的低效閾值近似為常數(shù)。
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。
Method:The drug were infused to stomach of mice and stomach residual rate, small intestine advance rate, stool quantity and pain threshold were observed.
方法：采用小鼠灌胃給藥的方法，分別觀察實驗動物胃內(nèi)容殘留率、小腸推進率、糞便排出量及痛閾值的變化。
