If faults opened up, no earthquake would occur because there would be no friction to lock them together.
如果断层裂开，也不会发生地震，因为没有摩擦力把它们合到一起。

Together with the practical application of the panel turnover gas-lock valve, the factors of the inherent character with the friction effect are also given in this paper.
结合生产实践分析了由于摩擦阻力而形成的翻板式锁气阀所固有的特性及其影响因素。
