刘茂

Liu Mao's publicly available information is limited, and no clear record of his identity or career has been found. Nevertheless, the three works collected here offer a rough picture of the fields he writes about: Principles of Urban Safety and Disaster Prevention Planning, Friction, Wear and Wear-Resistant Materials, and Theories and Methods of Accident Risk Analysis. Spanning urban safety, materials engineering and accident risk analysis, these titles all fall within industrial technology and popular science, and some are also classified as exam-related materials. Liu Mao's writing thus tends toward organizing engineering knowledge and introducing methods, with an emphasis on explaining principles and their practical application, aimed mainly at students, technicians and exam candidates in the relevant fields. Overall, his works reflect a broad perspective bridging safety science and materials engineering and offer some value for professional teaching and engineering practice.
