longitudinal split meaning in Chinese

纵裂

The result shows that under the effect of repeated impact load , the stress wave produces reflection in the metallurgical junction plane between coating and basal body , and forms stretch wave causing longitudinal split and angle split of coat ; the microcosmic spot pitting and deep layered peeling off occur in coating surface due to stress concentration ; the energy accumulation of impact loading causes rigidity variation and plastic deformation
结果表明：在多冲载荷作用下，应力波在涂层和基体的冶金接合面发生反射，形成拉伸波造成涂层的纵裂和角裂；在涂层表面由于应力集中，涂层表面发生微观点蚀和深层剥落；冲击载荷能量的积累，造成涂层试样硬度变化和塑性变形。
