| Abstract: | Based on the value of static theory,the measured expansion coefficient of the experimental liquid formula commonly used in laboratory measurements of physical balance in the body of ethanol expansion coefficient,the measurement results compared with the standard value,the relative error is small. Measurement principle of the method clear method is simple,measurement accuracy. |
