Chemistry Oxygen Demand化学需氧量
As for water pollution,chemical oxygen demand（COD）is an important measure of organic pollution in water.
在水污染监测中,COD,即化学需氧量,是衡量水体有机污染的重要指标。
参考来源 - 基于掺硼金刚石（BDD）膜电极的COD测定方法和TiOABM: The oxygen demand of myocardium increases acutely during excessive exercise and labor. Consequently blood flow in coronary arteries is relatively defcient, which results in relative ischemia/reperfusion injury.
目的:过度运动或超负荷体力劳动时心肌需氧量增加,而使冠状动脉相对供血不足,导致心脏发生相对缺血/再灌注损伤,其病理生理过程与缺血/再灌注损伤类似。
