A method to analyze the dynamics of piecewise continuous system is presented, based on it, the chaotic oscillation of a harmonically forced spring-mass system with friction is studied. The impact of friction and other parameters on the chaotic oscillation of this system is analyzed.

分析了系统参数和摩擦模型对系统混沌行为的影响；发现了摩擦模型的选取对系统动力学行为分析的重要性；揭示出在一定条件下，系统参数、环境条件或润滑条件的改变都有可能使系统进入无序的混沌运动状态。

Then think of just moving the laser head of the resistance encountered, careful observation revealed that the movement of laser head rail has a white grease has hardened, moving the laser head again here, the card does have a slight lag case !

这时想起刚才移动激光头时碰到的阻力，仔细观察后发现激光头的移动导轨上有一处白色的润滑脂已变硬，将激光头再次移到此处，确实有轻微的卡滞情况！

Today Petro-Canada is Canada's 11th largest company with important interests in such projects as Hibernia, Terra Nova, and White Rose; its gas stations remain a presence in most Canadian cities.

加拿大国营石油公司自1970年开始用二段加氢技术生产基础油并用於各类润滑油得调合，使其润滑油品性能迫近全合成油品得品质。

The Hobbesian problem is truly a problem, but in transcending it by the smoothing effect of social structure, we also introduce the possibility of disruptions on a larger scale than those available in the state of nature.

Hobbes的问题确实是一个问题，但通过借助社会结构的润滑效应来超越这一问题的同时，我们也引进了比在「自然状态」中可能出现更大规模分列的可能性。

A new cermet sinter with through micro-porous structure was developed by vacuum liquid phase sintering method, in which Al2O3-Ni-Cr-Mo-Si-Fe powder was used as the basic material, TiH2 and CaCO3 were used as the composite pore-forming materials and hominess grains was used as dispersal particles. The cermet sinter was then infiltrated with Ag-Cu-Pb-Sn at vacuum and formed a new high temperature self-lubricating material.

以TiH2和CaCO3为复合造孔剂，以硬质微细颗粒为惰性弥散质点，采用真空烧结法制备出具有贯通型微孔结构的Al2O3-Ni-Cr-Mo-Si-Fe系金属陶瓷烧结体，并在烧结体中浸渍Ag-Cu-Pb-Sn系浸渍型固体润滑剂制备出新型高温扩散自润滑材料。
