Week 4 Work and energy principle, conservation law of mechanical energy, moment of force, moment of inertia of rigid body, rotating law of rigid body with fixed axis.

第4周 功能原理、机械能守恒定律；力矩、刚体的转动惯量、刚体定轴转动定律。

Here is a different state of affairs from classical mechanics, where absolute uniform motion is quite meaningless because of Galileo's law of inertia.

这里的情况跟经典力学不同，在经典力学中，由于伽利略惯性定理的关系，绝对的匀速直线运动是毫无意义的。

D: Well the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性原则就是：运动中的物体要保持运动的状态，同时保持直线运动（惯性守则好像不是这么说的吧，请参看楼上的）。

Hence, new physics would take into consideration at least one of three possibilities: clock acceleration, a modification of the law of gravity, or modified inertia.

因此，新的物理原理可能至少是这三种可能性之一：时钟加速，修改引力定律或者修改惯性。

The Law of Inertia states that a body at rest tends to remain at rest unless acted upon by an outside force.

该法规定，一个机构在惯性往往停留在休息休息了，除非采取行动外力。

Galileo's conclusion, the correct one, was formulated a generation later by Newton as the law of inertia.

伽利略这个正确的结论隔了一代以后由牛顿把它写成惯性定律。

Classical mechanics, but Galileo, the creator of "the embryo form of law of inertia",with the incline experiment only attested to the falsity of Aristotle's proposition that "the force is the indispensable factor to maintain object movement", and not proposed what is the indispensable factor to maintain object movement.

牛顿第一定律被认为是经典力学的最基本定律之一，但"惯性定律雏型"的原创者伽利略用斜面实验只证伪亚里士多德的"力是维持物体运动不可缺少的因素"这一命题，并没有提出什么才是维持物体运动不可缺少的因素。

Through the characteristic parameters, the system's real-time moment of inertia is given. Then golden section adaptive control law and logic derivative control law both based on moment of inertia are designed. The two kind of control laws are combined to control the attitude of spacecraft and their simulation results are compared with the ones of PD control law which is designed based on the certainly-known system model. The results show that this adaptive control law is effective on the kind of time-variable system studied in this paper.

根据特征模型的参数推算了系统实时的转动惯量，设计了基于转动惯量的黄金分割自适应控制器和逻辑微分控制器，将这两种控制器相结合对带有可伸缩挠性附件的刚体进行姿态控制，仿真结果与基于确知系统模型所设计的变系数PD控制器相对照，表明了该自适应方法控制一类时变系统的有效性。

According to the law of mass moment of inertia and of momentum moment, the conditions for the complete dynamic balance of rotor inertial forces and moment of inertia in the rotary piston vacuum pump are put forward, with the rotor movement in single cylinder analyzed as basis.

根据质量矩定理和动量矩定理对单缸滑阀真空泵的转子运动状况进行了分析，分别提出了转子惯性力和惯性力矩完全动平衡的条件。

Explain this in terms of inertia and Newton's first law of motion.

请用所学的惯性和牛顿第一运动定律的知识作出解释。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
