在工厂突验室的定炭作业中,气体容量法是被最广泛采用的方法,其要点是:使试料中的炭份在氧流中高温燃烧变成二氧化炭,再将二氧化炭通入量气管,根据其吸收体积换算得到试样的含炭量。这个方法简捷而可靠,但因为二氧化炭气体的体积不仅决定於试样的含炭量,而且和样品重、气体温度 The gas volumetric method is the most widely used method for determining the volume of carbon in a factory laboratory. The key point is that the carbon in the sample is burned into carbon dioxide at a high temperature in an oxygen stream, and then carbon dioxide Through the amount of trachea, according to its absorption volume conversion obtained sample carbon content. This method is simple and reliable, but because of the volume of carbon dioxide gas is not only determined by the carbon content of the sample, but also with the sample weight, gas temperature
