Different concentrations of oxygen-bearing organic matter show different influence on the absorbance of alkali metals with different regularities .
有机物官能团上的差异也将对碱金属元素的吸光度产生不同的影响。
One way to measure the strength of an antioxidant is by its oxygen radical absorbance capacity or orac value .
其中一个方法来衡量其中抗氧化剂的作用的标准是抗氧化剂的氧自由基吸收能力或价值。
To study the effects of colored time on results precision of phosphoric acid content by ammonium molybdate spectrophotometric method in cane juice , absorbance of phosphoric acid standard solutions was determined at various colored time .
Absorbance can be read from650to750nm depending on the availability of appropriate filters ( microplate readers ) , or if the signal is too high , without significant loss in assay performance .
Chapter one deals mostly with basic thoeries and concepts on thermal radiation and absorbance of radiation , and then brings out the basic basis for remotely detecting the gas methane .
