【摘要】 介绍了电光浮力天平的基本原理、结构、工作原理。电光浮力天平的测量是通过光的投影来判断天平是否平衡,利用阿基米德定理,计算出配重物体受到的浮力,运用杠杆平衡的原理得出配重物体浮力的变化就是被测量物体的重量。试验证明:本浮力天平的研制是成功的,其灵敏度、最大载荷、精度都较高,并具有称量稳定,使用方便等优点。更多还原

【Abstract】 The basic method system structure and work elements of the electricity-light buoyancy balance are introduced. The equation of the electricity-light balance is judged by the projection of the light. Based on Archimedes theorem and the lever balance principle We can calculate the buoyancy’s variety of the balance objects. This variable equals to the weight of the measured object. The experiment has proved that the development of this buoyancy balance is successful. The sensitivity maximal load and precision of the buoyancy balance are high. It can weight stabilitily and be operated conveniently.更多还原
