近年来,陶瓷材料已发展为与金属、塑料并驾齐驱的第三种工程材料。从七十年代初石油危机以来,世界各国十分重视量大面宽的高耗能机械——汽车发动机的节能研究,并已取得相当大的成绩。研究结果表明,汽车发动机节能的最佳方案是研制绝热发动机和燃气轮机等节能型内燃机。精密陶瓷材料是实现这一目标的最有效的工程材料。 In recent years, ceramic materials have been developed with the third kind of engineering materials that match the metal and plastic. Since the oil crisis of the early 1970s, all countries in the world have paid great attention to the energy-saving research of high-energy-consuming machinery-automobile engines, and have achieved considerable success. The results show that the best way to save energy in automobile engine is to develop energy-saving internal combustion engine such as adiabatic engine and gas turbine. Precision ceramic material is the most effective engineering material to achieve this goal.
