概述了疲劳小裂纹试验方法航标的编制背景。论述了航标中几个主要技术问题，如，小裂纹试样和小裂纹监测方法的选择，三维应力强度因子K的确定，小裂纹数据有效性的判据及物理小裂纹门槛值。并且与ASTM E647-95a方法中附录X3进行了比较。
Compiling background of an aero-standard test method for measurement of small fatigue crack growth rates was outlined.Several main technical problems for the method were demonstrated,such as choice of specimens and methods of monitoring small-crack, determi-nation of three-dimensional (3D) stress intensity factor,small-crack non-interacting criteria as well as physical small-crack threshold.Comparision was also made between this method and Appendix X3 on ASTM test method E647-95a.
