【摘要】 本文认为 2 0世纪后 5 0年化学发展最重要的基本特征是在学科水平上的既分化又综合 ,产生这一特征的根本原因是科学技术整体化的需要。分化产生了新的三级分支学科 ,使学科内的分工更合理、更专业化 ;而综合则形成了新的二级分支学科 ,并使化学研究从传统的化学领域走向其它的科学领域。可以说 ,分化与综合是学科发展的原动力。在新的世纪 ,化学仍将沿着这一方向继续发展 ,并走向辉煌。但新的辉煌正向旧的传统的学科观念提出挑战 ,新的大化学学科观正呼之欲出。更多还原

【Abstract】 This paper considers that the most important basic characteristics of the chemical development in the late 50 years of 20tth century are both separation and synthesis on the firstgrade subject.The reason for these features lies in the need of scientific integration.Separation has produced a new branch of the third-grade subject and made the division in the subject more rationalizing and specializing;While the integration has formed a new branch of the second-grade subject,and made chemical research move from the field of traditional chemistry to the other scientific fields.In the new century,chemistry will continue to develop along the way and go towards brilliance.However,the new brilliance may result in the end of traditional chemistry,and lead to the crisis of modern chemical development.更多还原
