[0024] The present invention is further illustrated below in conjunction with the accompanying drawings and specific examples, and these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0025] The principle of the present invention is based on the ideal gas law, using the ideal gas equation PV=nRT, under the conditions of constant temperature T and ideal gas constant R, through three steady-state ideal gas processes, the ideal gas equations under three different pressures are obtained. Three pressure values need to be measured, and the unary linear equation between the pressure P and the volume V can be determined after solving to calculate the volume of the irregular object to be measured.
[0026] A device for measuring the volume of irregular objects with gas, as attached figure 1 As shown, it includes vacuum pump 1, pressure box A2, pressure box B3, gas tank 4, valve A61, valve B62, valve C63, ...
