生产航空航天陶瓷发动机零件的新方法美国材料科学家研究出一种生产航空航天陶瓷发动机零件的新方法，用这种方法可以制造出便宜的能经受很高温度和压力的陶瓷发动机零件。其关键是借助微波加热和烘烤陶瓷。新的陶瓷生产法是美国伊利诺州埃文斯顿西北大学的林思·约翰逊（... New Method for Producing Aerospace Ceramic Engine Parts American materials scientists have developed a new method for producing parts for aerospace ceramic engines by using this method to produce inexpensive ceramic engine parts that can withstand very high temperatures and pressures. The key is the use of microwave heating and baking ceramics. The new ceramic production method is Lynn Johnson of Northwestern University in Evanston, Illinois.
