说明：  化学方程式不仅表明了反应物、生成物和反应条件。同时，化学计量数代表了各反应物、生成物物质的量关系，通过相对分子质量或相对原子质量还可以表示各物质之间的质量关系，即各物质之间的质量比。对于气体反应物、生成物，还可以直接通过化学计量数得出体积比。通过此程序可以实现方程式的配平
(Chemical equations not only show reactants, products and reaction conditions. At the same time, the stoichiometric number represents the quantity relationship of reactants and products. The relative molecular mass or relative atomic mass can also represent the mass relationship between substances, that is, the mass ratio between substances. For gas reactants and products, the volume ratio can be directly obtained by stoichiometry. With this program, the equation can be balanced)
