摩擦

But on account of the many new technique and new structure applying on these system, it make the system become more and more complexity, especially exists some nonlinearity factors and the loading, friction, lubricate, wearing down, etc, so many uncertainty complication, as a result, to acquire the relative exactly toque parameter become very difficult.

但是，由于大量新技术，新结构在这些系统中的应用，致使这些系统愈来愈复杂，特别是一些非线性环节的存在和载荷，摩擦，润滑，磨损等大量不确定因素的影响，使较为准确的转矩信号很难获取。

Especially her later work (Friction: Undescribable 《摩擦:无以名状》; Salsa and Pink Noise 《粉红色噪音》) explores and stretches the limits of language.

从那时起，她开始对这样的诗歌主张提出越来越强烈的质疑，特别是她后来的那些作品，如《摩擦：无以名状》，《萨尔萨》和《粉红色噪音》，探索并扩展了语言的界限。

According to classical thermodynamics, the energy relations between forward and reverse Carnot cycles between two isothermic reservoirs satisfy the principle 'it is equal in quantity and opposite in direction'.

按经典热力学，工作在两恒温热源间的正、反卡诺循环能量满足：&大小相等，方向相反&的原则，而实际热机、制冷机与热泵，由于热阻、摩擦、涡流、热漏等不可逆因素的存在，正、反卡诺循环能量不再满足此原则。

Combined with the macro-morphology appearance analysis and working conditions of failure casing, the paper reached a conclusion that it is due to the impact and friction which come from the drill tools made the fatigue cracks formation on the casing thread root, and eventually leading to casing rupture failure, the material defects in failure casing accelerated crack initiation and growth.

摘 要：某井在钻井作业过程中，发生了上层Φ244.5 mm技术套管断裂失效事故，为了分析事故原因，对失效套管材料的化学成分、金相组织和力学性能进行了检测分析，结合套管失效形貌的宏观分析和套管使用过程中的现场工况分析，得出了套管螺纹发生断裂失效的原因是钻具对套管的撞击、摩擦，使套管螺纹根部产生疲劳裂纹，最终导致套管断裂失效，失效套管的材料缺陷加速了裂纹的萌生和扩展。
