Brief discussion on disciplinary development of chemical engineering based on dialectical materialist epistemology
To cultivate students'systematic view,holistic view,and historical development perspective of the discipline of chemical engineering,thereby enabling them to gain a deeper understanding of the disciplinary content and enhancing their engineering thinking abilities,the basic conditions for the establishment of the discipline and its dialectical development process were systematically expounded on the basis of principles of dialectical materialist epistemology.The unified research object and methodology constitute the fundamental prerequisites for the establishment of the discipline,while the large-scale chemical production process serves as the objective basis for the disciplinary establishment and development of chemical engineering.The chemical production process is typically comprised of two distinct types of processes:physical and chemical.The study of physical process leads to the establishment of the subfield of chemical engineering principles,while the study of chemical process leads to the establishment of chemical reaction engineering.Any process inherently involves two aspects:the direction and limits of the process,as well as its rate.Based on the study of process direction and limits,the subfield of chemical engineering thermodynamics is established,while the study of process rates falls within the purview of chemical engineering principles and chemical reaction engineering.Research methodology in discipline can generally be classified into three categories:mathematical analysis,mathematical modeling,and empirical method.Different subfields tend to emphasize and exhibit unique characteristics in their research methods,such as the preference for mathematical analysis in transport process,the primary use of mathematical modeling in chemical reaction engineering,and the emphasis on empirical method in chemical engineering principles.Based on dialectical materialism,the dialectical development process of the discipline was systematically expounded.The development of a discipline is a process of self-negation,and a complete dialectical development process necessarily undergoes two negations before achieving self-perfection.The discipline of chemical engineering has undergone two negations from integration to decomposition and then from decomposition back to integration,culminating in the establishment of chemical system engineering and ultimately forming a comprehensive disciplinary system,which perfectly illustrates the scientific nature and truth of dialectical materialism.Dialectical materialism provides us with a fundamental methodology for cultivating a correct perspective on disciplinary development.
