英国Ｂａｔｈ大学的Ｆ .Ｂｅｎａｂｉｄ教授及其研究组用一束激光将聚苯乙烯小球推进入空心的光纤管中。过去曾经用激光射枪成功地将粒子推入到毛细管内 ,但激光在通过毛细管时 ,由于在这类管壁上激光会迅速地泄漏 ,所以推进的效率不高。现在Ｂａｔｈ大学的研究组将毛细管用光 Professor F. Benabid at the University of Bath, UK, and his team used a laser beam to push polystyrene beads into a hollow fiber tube. In the past, lasers were used to successfully push particles into the capillaries. However, when the laser passes through the capillaries, the efficiency of the propulsion is not very high due to the rapid laser leak on such tube walls. The research team at Bath University now runs out of capillaries
