作用力与反作用力 meaning in English
action and reaction
Examples
- When two bodies interact , the force which body a exerts on body b is equal in magnitude and opposite in direction to the force which body b exerts on body a
两个物体之间的作用力与反作用力总是数值相等，方向相反，作用在一条直线上。 - Qianlong ball is a patent sport product , which is innovated by beijing qianlong sports company . this innovation is a milestone in the sports history since this action breaks the traditional ball simple action model and brings a branch new dual action model . qianlong company pays close attention to qianlong sports extension all the time . the company has established multiform qianlong ball clubs in different big cities as shenzhen , etc . in the year of 2003 , olympic qianlong ball club opened in national olympic center in beijing . this club is mainly responsible for training qianlong ball coaches and professional athletes for domestic and foreign countries
牵珑球是一项由牵珑体育用品公司拥有的发明专利产品，牵珑球运动可以说是体育运动史上一个重要里程碑，牵珑球运动突破的传统球类运动单一作用力运动形式，牵珑球运动是作用力与反作用力双立合而为一的一种新的运动形式。牵珑体育公司长期关注牵珑球运动的发展和普及工作，在深圳等国内许多城市有不同形式的牵珑球俱乐部， - The research shows that students misunderstand the relation between force and motion . gravity and action / reaction ; that in dc circuit , students of different age groups have the belief of " consumption of current " , " clashing currents " and " the battery as a constant current generator " ; that in understanding the concepts of electricity students lack th e knowledge of relating the micro with the macro ; and that students have serious difficulties in understanding the propagation of mechanics wave , the speed of wave and superposition , and do not make a distinction between the initial conditions and the medium properties of the system
具体表现在：学生对力和运动的关系、重力和平衡、作用力与反作用力存在一些误解；对直流电路，不同年龄的学生不同程度地存在电流消耗、碰撞电流、恒定电流源等观念，而且对电学概念的理解缺乏宏观与微观的联系；学生在机械波的传播、波速、波的叠加上存在严重的困难，对于机械波的传播学生不能区分初始条件和媒质特性，并错误地将动力学某些观念与机械波进行类比。
