摘　　要：在动、静载荷腐蚀疲劳试验条件下,针对应变测量中存在的严重零漂问题,提出了一种基于转换系数法的应变零漂消除原理和方法。试验结果表明,该方法具有明显的应变零漂抑制效果,应变测量数据可靠。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.

关 键 词：腐蚀疲劳试验 应变参数 转换系数 零 漂
