本文提出并分析了一种新型的激光辅助微悬浮机构，利用热蠕变流动，只发生在区域的间距是小的，沿沿着边界壁存在温度梯度。该机制的基本配置类似于激光辅助磁光记录或近场记录系统。一个半径为1毫米的圆板，其温度随半径的增加而线性降低，其温度比T/sub W中心//T/sub 0/为1.2，当浮动板和固定板之间的间距为0.1 /spl μ/m时，其承载能力约为3 mN。
This paper proposes and analyzes a novel laser-assisted micro levitation mechanism utilizing thermal creep flow which occurs only in regions where the spacing is small and temperature gradients exist along the boundary walls. The basic configuration of the mechanism is similar to the laser-assisted magneto-optical recording or near field recording system. A circular plate with a radius of 1 mm, whose temperature linearly decreases with increasing radius and whose temperature ratio T/sub W center//T/sub 0/ is 1.2, has a load-carrying capacity of about 3 mN when the spacing between the floating and fixed plates is 0.1 /spl mu/m.
