In this article,the technology of softening wood with chemicals was mainly discussed.By the experiments,2 species of wood and the relatedtreating process were selected.The treating effect、was further studies by de-termining the chemical compositions of untreated and treated wood as well asthe bending stability of treated wood.The resutls showed:①the concentrationof the chemical solution of 5%～6%,the temperature of 40℃ and the treatingtime of 20～24 hr.were suitable for softening wood; ②the dimension of treat─ed wood was unchanged under normal application conditions.
