简谐振动的周期公式为:T=2π(m/k)~(1/2)T为振动周期,m为振子的质量,k为弹簧的倔强系数.实践证明,用气垫导轨来进行这一验证,效果较好.使用器材:J 2125—2型气垫导轨(J 2126—1型小型气源)、倔强系数为k′_1和k′_2的弹簧(各两支)、配重金属块(数块)、秒表、天平、直尺等.实验装置:将气垫导轨水平放置在实验桌上,在滑块的两端各系一根弹簧,两根弹
The periodic formula of harmonic vibration is: T=2π(m/k)~(1/2)T is the vibration period, m is the mass of the oscillator, and k is the coefficient of the spring. It has been proved in practice that this is done with the air guide. Verification, the effect is better. The use of equipment: J 2125-2 air-cushion guide (J 2126-1 type small gas source), springs with stub coefficient k′_1 and k′_2 (two each), heavy metal blocks (number Block), stopwatch, balance, ruler, etc. Experimental device: The air-cushion guide is placed horizontally on the experimental table, one spring and two bullets are attached to each end of the slider.
