由于试样细观缺陷非均匀性的存在，导致岩石断裂主要由拉伸破坏引起，但拉剪混合破坏仍然存在，并对抗剪强度有较大的影响。
Due to the heterogeneity, rock failure mainly results from tensile damage but shear damage still exists, which has influence on the shear strength.
有效硫化体系的断裂伸长率、拉伸强度、撕裂强度、耐磨性、抗热氧老化性能最好。
The elongation at break, tensile strength and tearing strength of the HVSSBR cured with EV system are the best.
研究结果表明，浆膜断裂伸长率和断裂比功大的。拉伸模量小的浆料上浆的浆纱耐磨性较好，织造性能也较比良。
Results show that yarns sized by sizes with films of higher breaking elongation and specific work of rupture and lower initial modulus have better abrasive resistance and weaving performance.
