美国加州大学伯克利分校的科学家们,通过切断一对仅有一根头发万分之一大小的套叠微缩管,使内部微缩管在外部微缩管里面旋转,成功创造出微缩轴承。由此种方法制成的装置,即可以当做一根轴承,也可以当做一根弹簧。 与此同时。耶鲁大学的科学家们,正在使用由莱 Scientists at the University of California, Berkeley, have succeeded in creating miniature bearings by cutting a pair of telescopic microfilm tubes of just a tenth of a hair in size so that the inner microfilm rotates inside the outer microforbent. A device made in this way, either as a bearing or as a spring. at the same time. Yale University scientists, are using Levin
