目前高中学生的物理分组实验设备中,多有用一端封闭的细玻璃管(管中装有约10厘米长的水银柱)装在标尺上的“玻意耳——马略特定律实验”简单仪器.如果把这仪器再装上一些简单的附加零件,就可以充分发挥一物多用的作用:不但可以更好地进行玻意耳——马略特定律的实验,并可进行盖·吕萨克定律,查理定律,克拉拍龙气态方程等的实验. 所需的附加零件很简单,即在玻璃管开口的标尺端装一个象限弧的量角器.把量角器的一边嵌合在标尺侧缘,使其不能动摇.再把悬锤的悬线预先挂在轴上,然后使悬线贴近量角器的平面上.不用时,可把量
At present, the physical grouping experimental equipment for high school students is equipped with a thin glass tube with a closed end (the tube contains a mercury column of about 10 cm in length) and “Beauty-Martell’s Law Experiment” mounted on the scale. Simple instrument. If this instrument is reloaded with some simple additional parts, it can fully play a multi-purpose role: not only can better conduct Boehle - Marlow’s law experiment, and can carry out cover Lu Sark law, Charlie’s law, and Clara’s experiments on the gas-state equations. The required additional parts are simple: a quadrant arc protractor is mounted on the scale end of the glass tube opening. One side of the protractor is fitted on the side edge of the scale. To make it unshakeable, hang the hanging line of the hammer in advance on the shaft, and then make the suspension line close to the plane of the protractor. When not in use, the amount can be measured.
