托里拆利是物理学史上第一位准确地测出大气压值的科学家.著名的托里拆利实验至今仍是测定大气压值的有效方法.托里拆利是怎样设想出他的著名实验的?又是怎样确定大气压的数值的呢?
Torricelli was the first scientist in the history of physics to accurately measure the barometric pressure. The famous Torricelli experiment is still an effective method to determine the barometric pressure. Toricelli is how to imagine his famous experiment. How is the value of atmospheric pressure determined?
