| Abstract: | The paper accounts for the measuring error of the copper balls in mearuring pressure with the change of the environmental temperature.According to the quasi dynamic data for many kinds of copper balls under high and low temperature, temperature error law of copper balls is analyzed. The meaning of deriving unitive temperature correcting formula for pressure measuring copper balls is clarified. The means of forming the temperature correcting formula for copper balls is discussed. The correcting formula is derived by means of regression analysis .The feasibility of this formula has been tested. |
