目前在我国的化学界正经历着知识全面更新的阶段。其中有三股潮流颇令人瞩目,那就是理论化学领域中的“量子热”,有机合成领域中的“冠醚热”,以及化学工程领域中的“液膜热”。本文仅就液膜技术中的自然辩证法问题作些考察,以便在讨论液膜技术发生与发展的历史中揭示这一先进工艺的内在本质。 At present, the chemical community in our country is experiencing a stage of comprehensively updating knowledge. Among them, there are three trends that attract people’s attention. They are “quantum heat” in the field of theoretical chemistry, “crown ether heat” in the field of organic synthesis, and “liquid film heat” in the field of chemical engineering. This article reviews only the issue of dialectics of nature in liquid film technology to reveal the inherent nature of this advanced technology in the history of discussing the occurrence and development of liquid film technology.
