自有科学以来,学科间相互渗透交叉、碰撞所产生的火花就是科学发展的驱动力之一,也是许多创新性科学论点与方法产生的温床。实际上,一系列重大的科学理论、研究项目和工程技术都是不同方面和层次的学科交叉的系统。学科交叉已经形成了大量“成熟”的交叉学科,如:物理化学、生物化学、生物物理、生态学等;并且还将陆续形成重要的交叉学科。这些交叉学科大大地推动了科学进步,尤其在现代“大科学”发展趋势下,几乎已找不到没有学科交叉的“纯”科学问题。然而,在另一方面,传统学科的“保护”或“壁垒”主义又在有意或无意地强调“纯”学科,排斥其他学科的渗透和介入,从而不利于科学的发展。在国家自然科学基金的申请、 Since its own science, interdisciplinary interdisciplinary, sparks generated by the collision is one of the driving forces of scientific development, but also a hotbed of many innovative scientific arguments and methods. In fact, a series of major scientific theories, research projects, and engineering techniques are all interdisciplinary systems of different aspects and levels. Interdisciplinary has formed a large number of “mature” interdisciplinary, such as: physical chemistry, biochemistry, biophysics, ecology, etc .; and will gradually form an important interdisciplinary. These interdisciplinary subjects have greatly promoted scientific progress. In particular, with the development trend of modern “big sciences”, the “pure” scientific problems without interdisciplinary science can hardly be found. However, on the other hand, the “protection” or “barrier” doctrine of traditional disciplines, in turn, intentionally or unintentionally emphasizes “pure” disciplines and excludes the infiltration and involvement of other disciplines, thereby detrimental to the development of science.
