一种激光电火花光谱演示装置,将构成一种新的用以监控由制造厂、焚化炉及发电厂所排放出的有毒金属的处理方法的基础。美国加州山地亚国家实验室的研究者,使用该实验室装置,研制出一个能对持续排放作监控的样机(CEM)。这台样机在1994年秋季成功地通过了测试,并成为正在进行中的第二代改进机的设计基础。经调焦的激光电火花光谱发出脉冲激光束激励金属原 A laser EDM presentation device will form the basis for a new approach to monitoring toxic metals emitted by manufacturing plants, incinerators and power plants. Researchers at the Shanya National Laboratory in California, USA, used the lab to develop a prototype (CEM) that monitors continuous emissions. The prototype successfully passed the test in the fall of 1994 and became the basis of design for the second generation of the ongoing modernization. The focused laser EDM emits a pulsed laser beam that excites the metal
