Cailletet used a pressure of 300 atmospheres and a temperature of -29°, which latter was obtained by the evaporation of liquid sulphurous acid. Edward W. Byrn.十九世纪发明进展.
Pictet used a pressure of 320 atmospheres and a temperature of -140°, obtained by the evaporation of liquid sulphurous acid and liquid carbonic acid. Edward W. Byrn.十九世纪发明进展.
It is requisite that the receiver should be capable of bearing a pressure of at least six atmospheres, which is equal to 90 lbs. 弗雷德里克·科利尔·贝克维尔.伟大的事实.
Thus, when there are three atmospheres of gas under pressure, each bottle of soda-water contains four bottles full of gas, which are absorbed without perceptibly increasing its bulk. 弗雷德里克·科利尔·贝克维尔.伟大的事实.
