积分在短时蠕变和长时间蠕变条件下是路往无关的，而在过渡蠕变时期，其与路径也只是弱相关。

The J integral is path-independent for the short time creep and long one, while in the transition period, it is weakly path-dependent.

提出了一种在弱目标检测系统中，线列或面阵红外焦平面的非均匀校正算法-基于可变积分时间和均衡噪声的两点现场校正算法。

A new method, named two point IRFPA nonuniformity correction method based on integration adjustment and noise equilibrium , to correct IRFPA nonuniformity in dim target detection system was presented.

作为所得结果的应用，讨论了弱奇异积分方程解的存在性问题。

As an application we utilize the results presented in this paper to study the existence problem of solutions for a class of weakly singular integral equations.
