人们都知道,高分子材料的大量应用,有机化合物、药物的广泛生产和分子生物学、遗传工程研究的蓬勃开展等,都是与有机化学这一基础科学的大发展直接相关的。但数十年前,有机化学还曾被一些人看作是一种“艺术”。如今,它却已成为一门既相当成熟而又活力充沛的重要学科了。这一惊人的变化,正反映了物理有机化学的作用和发展,物理有机化学工作者从结构和反应机理两大方面,为有机化合物的合成和结构工作寻找有指导性意义的概念和规律。因此,从这个意义来说,物理有机和有机化学以及有关生产实践的关系,就是理论和实践的关系。同时,它又是有机化学的一个组成部分。在近年的原始文献中,它约占有机化学的三分之一。卅余年前,它已被列为有关学科研究生的必修课程之一。掌握并运用了物理有机化学的概念、方法的科技工作者,对于近几十年来有机、高分子工业的飞速发展,是起了重要作用的。生产斗争是推动科学发展的根本动力和物质基础,而自然科学实践又有其相对的独立性。科学研究 It is well known that the large number of applications of macromolecular materials, the extensive production of organic compounds, drugs, and molecular biology, and the vigorous development of genetic engineering are all directly related to the great development of organic chemistry as a basic science. But decades ago, organic chemistry was also seen by some as “art.” Today, however, it has become an important discipline that is both mature and vibrant. This amazing change reflects the role and development of physical organic chemistry. The physico-chemical workers seek the concepts and laws guiding the synthesis and structure of organic compounds from the two aspects of structure and reaction mechanism. Therefore, in this sense, the relationship between physical organic and organic chemistry and related production practices is the relationship between theory and practice. At the same time, it is an integral part of organic chemistry. In recent years the original literature, it accounted for about one-third of organic chemistry. More than a year ago, it was listed as one of the compulsory courses for graduate students in science. The scientists and technicians who have mastered and applied the concepts and methods of physical organic chemistry have played an important role in the rapid development of the organic and polymer industries in recent decades. The struggle for production is the fundamental impetus and material foundation for promoting scientific development, and the practice of natural science has its relative independence.
