However, the pseudo-triaxial strengths of several rocks from the best fitting solutions have great scatterness from the real magnitudes. Also, it does not correspond to the experimental results that rock has the same strength under conventional triaxial compression and tension; the maximum increase of strength from intermediate principal stress has a linear relation with the minor principal stress; and the first-order derivative of strength has an interruption at the peak point.

此外，统一强度理论认为岩石三轴伸长强度与常规三轴压缩强度相同，在最小主应力恒定时中间主应力引起的强度最大增加值随最小主应力线性增加，且强度关于中间主应力的一阶导数在峰值点是不连续的，这些都与试验结果不能完全协调。

Anterior cingulate cortex is an important part of the limbic system and the high-level center of brain, which not only receives all kinds of information from subcortex, but also is reliably activated by peripheral noxious stimulus, and has been a hotspot of pain exploration. Though the adequate data has already been collected about the ACC modulation of sensatory and emotional component of pain, the studies were almost confined to the aspect : how the ACC receive nociceptive information.
