the remaining quantities是啥意思？

Diffusion of Carbon Monoxide in the Lungs

Diffusing capacity is usually measured for carbon monoxide, for the very practical reason that affinity of carbon monoxide for haemoglobin is so high that the partial pressure of the gas in the pulmonary capillary blood remains effectively zero. The formula for calculation of this quantity then simplifies to

CO在肺部的弥散

通常测量CO的弥散量，由于CO对血红蛋白的亲和力非常高，以至于（没有游离的CO）肺毛细血管中实际CO分压为零。该计算公式简化为

CO弥散量= CO摄取量/肺泡PCO

There are no insuperable difficulties in the measurement of either of the remaining quantities on the right-hand side of the equation, and the methods are outlined at the end of the chapter. Traditional units for CO diffusing capacity are mL.min21.mmHg21, although in SI units the volume of CO is usually described in molar terms, that is, mmol.

min21.kPa21.

程式右侧任一剩余量的测量都没有不可克服的困难，本章末尾概述了这些方法。CO弥散量的传统单位为ml/（min•mmHg），尽管以国际单位制表示，CO的体积通常以摩尔表示，即mmol/（min•kPa）
