目前，化学物质的转变主要是依靠分子的重构，即分子反应.如果常态下可以任意改变分子中的某个原子，而非替换原子；或者直接将某些特定原子，重组成新的原子，这将把原子反应发展为普通实用的化学反应.
At present, the transformation of chemical substances mainly depends on the reconstruction of molecules, i.e., molecular reactions. If an atom in a molecule under normal conditions can be arbitrarily changed instead of replacing atoms，or some specific atoms can be directly reorganized to afford new atoms, it will make atomic reactions be transformed into practical chemical reactions.
