The microfracturing process of Jinping marble specimen in Sichuan province under uniaxial compression is recorded by using the testing scheme. Quantitatively investigated the propagation and coalescent of cracks at meso-scale with digital technology, the basic geometric information of rock microcracks such as area, angle, length, width, perimeter, are obtained from binary images after segmentation. The failure mechanism of specimen under uniaxial compression with the quantitative information is studied from macro/micro scopic perspective. The result shows that during the damage of the specimen the distribution of microcracks in the whole specimen are still subjected to exponential distribution with some microcracks concentrated in certain regions.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
