公路和机场路面油和燃料污斑的出现,大大地减少了轮胎与道路的摩擦力,特别在转弯处和高速行驶时将会引起大量车祸。用已知喷火烧净的方法,由于迫使火焰从上向下地工作,而不够有效。由于表面粗糙,机械清洗法也不十分有效。我们试验了利用激光束清洗油和燃料污 Road and airport road surface oil and fuel stains, greatly reducing the tire and road friction, especially in the corner and high-speed driving will cause a lot of car accidents. In the known method of spraying fire, it is not effective enough to force the flame to work from above to below. Due to the rough surface, mechanical cleaning method is not very effective. We tested the use of laser beam cleaning oil and fuel pollution
