摘要
该文以盐水溶液为例,利用光栅衍射通过测量不同密度引起吸光度的变化,拟合出吸光度与密度的函数关系,从而实现对透明液体密度的测量。该方法有效地解决常规测量方法操作繁琐、理论复杂及仪器腐蚀等对测量密度造成不便的问题。同时,实验表明,测量精度可以达到99%,证实利用吸光度测量透明液体密度方法的可靠性及有效性。
In this paper,taking brine solution as an example,the change of absorbance caused by different density is measured by grating diffraction,and the functional relationship between absorbance and density is fitted,thus the density of transparent liquid is measured.This method can effectively solve the problems of tedious operation,complex theory and instrument corrosion of conventional measuring methods,which cause inconvenience to measuring density.At the same time,the experiment shows that the measurement accuracy can reach 99%,which proves the reliability and effectiveness of the method of measuring the density of transparent liquid by absorbance.
