มีผลลัพธ์ที่ไม่แสดงผลอยู่ | Halometer | n. [ Gr. "a`ls, "alo`s, salt + -meter. ] An instrument for measuring the forms and angles of salts and crystals; a goniometer. [ 1913 Webster ] | | Barometer | n. [ Gr. ba`ros weight + -meter: cf. F. baromètre. ] An instrument for determining the weight or pressure of the atmosphere, and hence for judging of the probable changes of weather, or for ascertaining the height of any ascent. [ 1913 Webster ] ☞ The barometer was invented by Torricelli at Florence about 1643. It is made in its simplest form by filling a graduated glass tube about 34 inches long with mercury and inverting it in a cup containing mercury. The column of mercury in the tube descends until balanced by the weight of the atmosphere, and its rise or fall under varying conditions is a measure of the change in the atmospheric pressure. At the sea level its ordinary height is about 30 inches (760 millimeters). See Sympiesometer. Nichol. [ 1913 Webster ]
Aneroid barometer. See Aneroid barometer, under Aneroid. --
Marine barometer, a barometer with tube contracted at bottom to prevent rapid oscillations of the mercury, and suspended in gimbals from an arm or support on shipboard. --
Mountain barometer, a portable mercurial barometer with tripod support, and long scale, for measuring heights. --
Siphon barometer, a barometer having a tube bent like a hook with the longer leg closed at the top. The height of the mercury in the longer leg shows the pressure of the atmosphere. --
Wheel barometer, a barometer with recurved tube, and a float, from which a cord passes over a pulley and moves an index. [ 1913 Webster ]
