ChemicalReactionQ
ChemicalReactionQ
ChemicalReactionQ[rxn]
如果 rxn 是一个有效的 ChemicalReaction 表达式，返回 True，否则返回 False.
范例
打开所有单元 关闭所有单元基本范例 (2)
ChemicalReactionQ[ChemicalReaction[Association[ChemicalFormula[{"Al" -> 1, "P" -> 1, "O" -> 4}] -> 1,
ChemicalFormula[{"Ca" -> 1, {"N" -> 1, "O" -> 3} -> 2}] -> 1] ->
Association[ChemicalFormula[{"Al" -> 1, {"N" -> 1, "O" -> 3} -> 3}] -> 1,
ChemicalFormula[{"Ca" -> 3, {"P" -> 1, "O" -> 4} -> 2}] -> 1]]]ChemicalReactionQ["AlPO4 + Ca(NO3)2 -> Al(NO3)3 + Ca3(PO4)2"]检验前先将字符串转换成 ChemicalReaction：
ChemicalReactionQ[ChemicalReaction["AlPO4 + Ca(NO3)2 -> Al(NO3)3 + Ca3(PO4)2"]]范围 (1)
当给出无效输入时，ChemicalReaction 将返回未计算的表达式：
ChemicalReaction[junk]
MatchQ[%, _ChemicalReaction]用 PatternTest 构建更具辨别力的模式：
MatchQ[%%, _ ? ChemicalReactionQ]
