Degree of absorption along and perpendicular to the main optical axis was studied for some uniaxial minerals, using several types of spectrophotometers.

用几种分光光度计研究了一些一轴晶矿物平行和垂直于主光轴方向的吸收程度。

Because of the difficulties caused by absorption by oxygen and the low output of conventional spectrophotometers at this wavelength, measurements are more conveniently made at 205 nm, where the absorbance is about half that at 190 nm.

由于氧气吸收带来的困难和常规分光光度计在这个波长的低输出。205nm更常见地用于测量。这里的吸收大概只有190nm的一半。

If the food is a transparent liquid such as wine, beer, or grape juice, or if a colored extract can be obtained from the food, then various types of colorimeters or spectrophotometers can be used for color measurement.

如果食品是一种透明液体，或者如果可以从食品中获得有色提取物质，那么就可以用各种类型的比色计或分光光度计进行色泽的测定。
