Using newton mechanics method discussion about conservation condition of mechanical energy , we get the conservation under zero rotation and implict time in potential formula 摘要本文用牛顿力学方法分析了机械能守恒的条件，指出只有力满足旋度(方程式略)的条件，而且在势能的表达式中不显含时间，机械能才守恒。
A bit of an exaggeration , perhaps , but the point was that even in the theoretically deterministic world of newtonian mechanics , only a small amount of complexity is needed to make practical prediction well nigh impossible 这也许有点夸张，但关键是即使在牛顿力学的理论决定学界，仅仅是少量的复杂因素也会给实际预测带来不确定性。
A bit of an exaggeration , perhaps , but the point was that even in the theoretically deterministic world of newtonian mechanics , only a small amount of complexity is needed to make practical prediction well nigh impossible 这也许有点夸张，但关键是即使在理论上由牛顿力学所决定的世界中，仅仅是少量的复杂因素也会给实际预测带来不确定性。
Quantum mechanics is a more fundamental theory than newtonian mechanics and classical electromagnetism , in the sense that it provides accurate and precise descriptions for many phenomena that these " classical " theories simply cannot explain on the atomic and subatomic level 量子力学与牛顿力学和经典电磁学比是更为基本的理论，感觉上它对许多现象提供了精确和精准的描述，这些“经典”理论只不过不能解释原子与亚原子水平。
Hence , analytical expressions are developed to allow for characterization of the vehicle ’ s dynamics early in the design cycle . the method involves a two - dimensional hypersonic aerodynamic analysis utilizing newtonian theory , coupled with a one - dimensional aero / thermo analysis of the flow in the engine of the vehicle 方法中包括一个应用牛顿力学理论的二维的高超声速空气动力学分析以及一个一维的气动/热分析,后者用于模型发动机中的流体分析。
In newtonian mechanics , we say the moon is attracted by the earth , so it orbits around the earth . in the theory of general relativity , we will say the earth affects the spacetime around it , thus the moon is no longer moving in a straight line , instead it goes around the earth . just like a marble will not move in a straight line on an uneven table 牛顿力学认为月球绕地球旋转，是因为月球受到地球引力的吸引但广义相对论的说法则是地球的质量扭曲了附近的时空，月球在不平坦的时空以最自然的方式运行，结果走出了一条绕著地球转的曲线，情况就如弹珠在不平坦的地面走，会左摇右摆一样。
Coriolis force is the earth rotation movement in fluence result , according to the newtonian mechanics principle and the law of motion , the analysis coriolis force the production and the essence , asks to calculate coriol is force the size and the direction , finally have discussed coriolis force the influence and the application 摘要地转偏向力是地球自转运动影响的结果，根据牛顿力学原理和运动定律，分析地转偏向力的产生和实质，求算地转偏向力的大小和方向，最后探讨了地转偏向力的影响和应用。
In addition to the basic concepts of newtonian mechanics , fluid mechanics , and kinetic gas theory , a variety of interesting topics are covered in this course : binary stars , neutron stars , black holes , resonance phenomena , musical instruments , stellar collapse , supernovae , astronomical observations from very high flying balloons ( lecture 35 ) , and you will be allowed a peek into the intriguing quantum world 除了牛顿力学、流体力学和气体动力论的一些基本概念外，本课程还包括一些有趣的主题：双子星、中子星、黑洞、共振、乐器、 ? p坍塌、超新星、从飞得很高的气球上进行天文观测（第35讲） ，并且你能感受到量子世界的迷人魅力。
The form - finding problem is always solved by the deconstruction conception of newton mechanics . but tensegrity system includes both structural conception and mechanism conception ; the dynamic means of investigating tensegrity may have more advantage . the argument between the strut continuous and discontinuous always exists in engineering domain 张拉整体体系的找形问题一直沿用牛顿力学中的解构概念，但作为张拉整体这一既包含结构概念但又需要一定条件才能成形的体系，从动态的角度考虑往往能对张拉整体的成形有更深入的理解。
