Mean residence time ( MRT), another measure of drug elimination, is the average time a drug molecule remains in the body after rapid IV injection. AfteranIVbolus,平均驻留时间(MRT)是表示药物消除的又一个测量值,是指某种药物快速静注后,其药物分子滞留在体内的平均时间。
The model of plasma chemistry was developed to predict the appropriate electron mean energy and flow rate and discharge pressure for the generation of singlet oxygen molecule, based on physical chemistry with a simple reaction model. 建立了基于分子反应动力学的氧等离子体化学反应模型,该模型包括了电子与氧分子,以及氧原子与氧分子的碰撞反应过程。
