Abstract:
The methods of common temperature correct ion , the meaning of quas-i dynamic calibrat ion on copper cylinders and the method of making table of copper cylinders are presented. Data of quas-i dynamic calibrat ion for pressure-measuring copper cylinder under a different temperature are analyzed. According to the calibrat ion data, temperature correct ing formula is derived by reg ression analysis. It is testified by the experiment s on drop-hammer dynamic pressure calibration system that the formula is feasible. T his formula can be used to calculate the correct ing value of pressure w hen copper cylinders work under nonstandard temperature . It can also be used to make temperature correct ing table.
