1)  Opening rate
裂口率
2)  Crack
裂口
1.

2.
For the purpose of the energy economy and cost reduction through prolonging the service life of the apron,starting with the discarding of the useless apron,analysis is given to the discarding of the useless apron regarding crack,fracture,worn-out.
为了延长胶圈的使用寿命,使纺织企业节能、降耗,从胶圈的报废原因入手,重点对裂纹、裂口及磨损造成的胶圈报废进行了分析,通过生产应用说明新型高耐磨、耐屈挠胶圈从材料改性入手,采用"三元"并用工艺,优化胶料配方,极大提高其抗臭氧能力和物理力学性能,是最为理想的"节能、科技、环保"型产品,并强调胶圈的制造与应用管理之间应紧密配合,互相协作,才能真正稳定和提高纺纱质量。
3)  lack of compound and breach
缺胶裂口
4)  split mechanism
裂口机制
1.
