At the end of Palaeoproterozoic (ca.1 600 Ma or 1 800 Ma), along with the Machonlyong Sea closed, the Rangrim and Gwanmo microcontinents became a whole massif through collision, which called Machonlyong motion (corresponding to Luliang motion in China).

古元古代末（约1600或1800 Ma），随着摩天岭海闭合，狼林微陆块与冠帽微陆块通过碰撞聚合而形成一个整体，称为摩天岭运动（可以对比中国的吕梁运动）。

Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.

提出了一种新型基础隔震模型，即带限位装置的摩擦隔震体系；基于此隔震模型，利用Floquet理论研究地面谐运动下S-LF结构的运动特性；并利用高精度的精细时程积分法，通过对地震作用下S-LF动力响应的计算，绘制了上部结构最大加速度反应谱和基底最大滑移量反应谱，并研究了各种结构参数对隔震的影响；通过与恢复力摩擦隔震系统和纯摩擦力滑移隔震系统的比较表明，S-LF的隔震性能优于P-F和R-FBI；对计算实例的分析发现，地震作用下S-LF结构的层间最大剪力和最大绝对加速度反应分布较一般传统结构有很大区别。
