摘要
介绍一种具有三维激光定位及调温器件的液体粘滞系数测量装置。此测量装置利用在量筒上安置了水平和竖直的四组光电门可以实现激光束的三维精准定位,保证小钢珠沿量筒中心轴下落,并精准测量钢珠的下落时间,调温控温装置可实现不同温度下的测量液体粘滞系数的要求。新测量装置具有实验过程直观、操作简便、测量数据准确、重复性好等特点,在科学研究以及大学物理实验教学领域具有一定的应用。
A kind of measuring instrument for liquid viscosity coefficient using 3D laser positioning and temperature controller was introduced.The measuring device uses the three horizontal and one vertical placed laser photoelectric gates on the measuring cylinder to realize three-dimensional precise positioning of falling steel beads,the drop of small steel beads along the central axis of measuring cylinder,and precise measurement of falling time of steel beads.One can measure the liquid viscosity coefficient at different temperature using the temperature controller.The new measuring device has the characteristics of intuitive experimental process,simple operation,accurate measurement data and good repeatability.The instrument can be useful in scientific research and general physics experiment teaching.
