【Abstract】 Serious problem of zero-drift is existed in the measuring of strain parameter under the condition of dynamic and static pressure of corrosion fatigue test. To solve the problem, a new method of eliminating zero-drift based on conversion coefficient is put forward. The test result indicates that the zero-drift existed in the strain parameter is eliminated obviously and the data measured are reliable.更多还原
