1) optical density quantitation
光密度定量
2) thin-layer chromatographic densitometry
薄层色谱光密度(定量)法
3) Quantitatively photometry

4) photo flux density
光量子密度
1.
CO 2 concentration and irradiance in maize canopies were measured with an infrared gas analyzer and quantum sensor The results indicated that diurnal changes of photo flux density (PFD) were a single peak curve Radiation interception rate of high yield breed canopies was above 95%, and transmitting rate of light on middle layer of canopies was above 25%.
结果表明 :3种株型玉米品种冠层内光量子密度的日变化呈早晚低、中午高的单峰曲线变化。
6) mass optical density
质量光密度
补充资料:细显微分光光度定量术
是应用显微分光光度计(microspectrophotometer)对组织和细胞内化学成分进行定量分析的技术。其基本原理是细胞内某种物质的含量不同,其杂色反应的深浅一,对一定波长的光吸收也不同,可通过测定其光密度值(od值)进定量分析比较 。
