魯延齊夫和西古羅夫斯基所提出的不用水銀能演示波意耳—馬略特定律的儀器毫無疑問是值得注意的,但是這些儀器的構造還是相當複雜。下面提出一種此較簡單的演示波意耳—馬略特定律的裝置。 這個裝置是用物理實驗室裏已有的簡單儀器和零件裝配成的。這些簡單儀器和零件就是:帶有固定器的三脚架、演示用的壓强計、金屬螺 The instruments proposed by Ludvizov and Sigurovski for the demonstration of the Boyle-Malinois law without mercury are undoubtedly of note, but the construction of these instruments is quite complex. Here is a simpler demonstration of Boyle-Mallory’s law. The device is assembled from simple instruments and components already in the physical lab. These simple instruments and parts are: a tripod with a holder, a pressure gauge for demonstration, a metal snail
