中文摘要：

化学工程的原理和知识已经应用于冶金、材料、能源、环境、生物等过程加工领域，因此化学工程可以更名为过程工程．化学工程现有的三传（动量传递、质量传递和热量传递）一反（化学反应）理论仍然是过程工程的主要基础理论，但必将在此基础上产生新的过程工程基础理论．随着计算机技术和测试技术的迅速发展，过程工程的研究范围将向下深入到观测和预测微观与介观尺度的结构和界面，向上扩展到宏观尺度的设备和工厂的系统集成，必将涉及结构、界面与多尺度问题．传统的平均方法忽视不均匀结构与界面的影响，造成对结果预测的偏差和放大困难，应当用考虑不均匀结构和界面影响的多尺度方法取代．此外，当前人类正面临能源和资源短缺、环境污染问题的挑战，过程工程的绿色化和集约化已成为各国科技界关注的焦点．在过程工程的研究中获得的有关结构、界面、多尺度、绿色化和集约化的重要原理和方法将成为过程工程基础理论的新内容．

英文摘要：

The principles and knowledge of chemical engineering has been applied into many processing fields such as metallurgy, materials, energy source, environment, bioengineering and so on. Therefore the chemical engineering could be renamed as process engineering. The present theories on heat transfer, mass transfer, momentum transfer, and chemical reaction for chemical engineering are still the basic theories for process engineering. However, it is inevitable and possible to produce new basic theories for process engineering. Along with the fast development of computer technology and measurement instruments, the research range of process engineering is extended to cover from observation and prediction of the micro-scale structure and interface to the system integration of the macro-scale equipment and plant, which refers to the structure, interface, and multi-scale issues. The methodology of averaging, which neglects the influences of the heterogeneous multi-scale structure and interface, should be replaced by the multi-scale methodology. In addition the shortage of energy resource and natural resources, the pollution of the environment have become the challenging problems facing to the mankind. The green operation and optimal integration of process engineering have become focal points of researchers. The principles and methods on the structure, interface, multi-scale, green operation, and optimal integration of process engineering should be the contents of the new basic theories for process engineering.
