摘要
介绍一种室内开展静水压强测定的试验装置,即静水压强及真空仪。该仪器可实现在液体表面压强大于、小于及等于大气压强的条件下,试验人员测定液体内部不同位置的压强大小。通过试验,学生能较好地掌握静水压强的基本方程,理解几个关于压强的重要概念,同时,该试验的开展,使实验教学效率和效果明显得到了提高。具有一定的实践教学意义及推广意义。
This article describes a test apparatus which can measure hydrostatic pressure in the indoor environment. It is the " hydrostatic pressure and vacuum instrument. " The instrument can be operated when the liquid surface pressure is greater than, less than or equal to the atmospheric pressure conditions. The test person can measure the liquid pressure at different locations inside the liquid. Through experiments, students can better grasp the basic equation of hydrostatic pressure, understand some important concepts about the pressure. By the trial, the efficiency and effectiveness of experimental teaching are significantly improved. It has a certain meaning and significance to promote the practice of teaching.
