阐述了截面为方形和圆形的管道尺寸减小时，比表面积以10倍的速度增加，导致表面力包括各种分子间作用力的作用加强。当尺寸在1nm-1μm范围内，流体的压力损失与分子间作用力成正比，与微管道特征尺寸的平方成反比。同时，由于尺寸的减小，强化了微通道内流体的质量和动量传递过程。

Abstract:The decrease in size of the pipe with square or circular section often results in 10 times m- crease of the specific surface area and the strengthening of the surface force including all kinds of inter- molecular forces. When the size is in 1 nm- 1 μm, the pressure loss is in proportion to intermolecutar forces and in inverse proportion to the square of the characteristic dimension. At the same time, due to the decrease in size, the quality and momentum transfer is strengthened in micro-channels.
