Abstract:
The paper accounts for the measuring error of the copper balls in mearuring pressure w ith the change of the environmental temperature. According to the quas-i 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 unit ive temperature correct ing formula for pressuremeasuring copper balls is clarif ied. T he means of forming the temperature correcting formula for copper balls is discussed. The correct ing formula is derived by means of reg ression analysis . T he feasibility of this formula has been tested.
