| 摘 要： | 磁力和重力均为非接触的力，当作用于磁性液体上的磁力和重力方向相同时，磁性液体处于超重状态；当作用于磁性液体上的磁力和重力方向相反时，磁性液体处于失重状态；当作用于磁性液体上磁力和重力相互抵消，磁性液体呈饱和磁化状态且处在均匀梯度磁场区域中时，磁性液体被表面张力约束成球体，磁性液体处于微重力状态。这一发现使我们在地面上能经济的、方便的、长时间的制造流体的小区域微重力环境，为研究微重力状态下的流体科学、生命科学，材料加工和器件开发等提供了新的方法。

| Abstract: | Magnetic force and gravity are both untouched force.Magnetic fluids will be in the overweight when magnetic force and gravity are in the same direction.Magnetic fluids will be in the weightlessness when magnetic force and gravity are in opposite direction.What is significant is that when magnetic fluids present saturation magnetization in magnetic field with uniform,and at the same time,gravity and magnetic forces counteracts in magnetic field with uniform gradient,the surface tension of magnetic fluids will be restrained to sphericity,thus in a state of microgravity.This discovery enalbes us to create an economical,convenient and durable microgravity environment to produce fluids on the ground-based,and provide new ways to carry out researches in state of microgravity in such areas as fluid physics,life science,material treatment and device exploit etc. |
