摘要
采用时差法测量超声波速度,选择葡萄糖、NaCL溶液样品,通过控制变量法、计算机拟合得到两种样品声速与温度和浓度两参数函数关系式,给出一种新的测定可溶性物质浓度的方法,实验结果在工业生产上有实用价值,同时也为多参数实验公式的建立提供思路。
In this experiment,the samples of glucose solution and NaCl solution with different temperature and concentration were selected.using time difference method,the ultrasonic velocity was measured by means of the control variable method,the relationship of sound velocity between the two parameters of the temperature and concentration was obtained by computer fitting.The experimental results have practical value,and then it provide ideas for how to establish the multi-parameter equation.
