在化学实验中，每种试剂都要用标签标明清楚，根据印码机的原理，制作一个标签号印机，可使填写标签的工作更简便。物质的化学名称，许多是“某化某”或“某酸菜”，有的可能前面再加一个“高”。“亚”、“偏”、“过”等或者“化”和“酸”后面加个“亚”。“氢”，这些名称 In chemical experiments, each reagent must be clearly marked with a label. According to the principle of the printer, a label printer can be created to make filling the label easier. The chemical names of the materials are many “a certain” or “sauerkraut”, and some may be preceded by a “high.” “Asia,” “partial,” “over,” or “chemical,” and “acid,” add a “sub”. “Hydrogen,” these names
