In the same way failure area is not single andis more complex with decrease of scale of specimens. And failure shape ismore close to quasi-brittle failure. It varies with homogeneousness that thescale of specimens at which failure shape changes.(3) The failure shape of homogeneous specimens with crack is controlledby crack. But that of heterogeneous specimens with crack is controlled bycrack and heterogeneousness.(4) Acoustic emission doesnt appear until homogeneous specimens fail.

但对于不同均质度，试件破坏形态发生变化的尺度也不同；(3)对于均质度较高的含裂纹试件，试件的破坏形态主要受裂纹控制，而对于均质度较差的含裂纹试件，试件的破坏形态由试件材料的非均匀性和裂纹共同控制；(4)均质度较高的试件，破坏前，试件内不出现声发射，破坏瞬间，声发射在某些部位同时出现，且随尺度增大，试件声发射能量增大，声发射区趋于集中。
