摘要
介绍了两种简便、经济的裂纹扩展监测方法，并详细分析了这些方法在石膏板断裂实验中的实验结果，阐明了裂纹起裂速度与其动力过程和约束条件相关且为一变量。分析了这些测试方法所产生的误差，提出了修正方法。
The two methods to monitor crack propagation are developed and a thorough analysis is made for the result of the two methods in break experiment of gypsum plate. It is expounded that the starting velocity of crack propagation is a variable and related to the dynamic process and restrained condition. Also, the error discussion and correction methods are both included.
