According to the results of path analysis, the direct effect and the degree of determination on yield of spike and grain character arranged as follows. The grain per row was first, the 1000-seed weight second, and the Spike length the last. 穗长、行粒数与产量相关极显著,千粒重与产量相关显著。通径分析结果表明:行粒数对产量的直接作用和决定程度最大,千粒重次之,再次为穗长。
The erosion mechanism at 90 degrees includes block exfoliation, the plastic deformation of binder phase and the extrusion of the carbides, meanwhile, the brittle fracture character has also been observed with a speed of 420 meters per second. 90°冲蚀机制包括块状剥落,粘结相的塑性变形和碳化物的挤出,420m/s冲蚀的粘结相还表现出了脆性断裂的特点,块状剥落是质量磨损率升高的主因。
