日本一大学研究成功用激光照射石墨制作钻石薄膜的新技术。这项新方法是，在大约五千分之一大气压的稀薄氧气中，用激光照射石墨，然后把石墨蒸发形成的碳气，喷向温度为５５０摄氏度的人工蓝宝石（氧化铝）板，碳就沉积下来。板上形成的石墨与氧发生反应，燃烧后就剩下钻石晶?
A Japanese university to study the success of laser irradiation of graphite to produce new diamond film technology. The new method is to irradiate the graphite with a laser at a lean oxygen of about one fifth of an atmosphere and then inject the carbon gas formed by the evaporation of the graphite into an artificial sapphire (alumina) plate at a temperature of 550 degrees Celsius, Deposited. The graphite formed on the plate reacts with oxygen, leaving the diamond crystal after burning?
