Abstract: A surface treatment method for metal parts includes a polishing step of supplying and discharging a cleaning liquid into and from a barrel tub while mass including a metal part and a medium is caused to flow in the barrel tub, so that a surface of the metal part is polished. The polishing step is carried out at least once. The polishing step includes a final finish polishing process in which a final finish medium which is free from abrasive grain or which consists of a synthetic resin base material and is free from abrasive grain or which is made by binding abrasive grain of not more than 10 wt % and a synthetic resin binding material together and is free from alumina is used as the medium.

Abstract: A reaction of a fluid in a reaction chamber is satisfactorily performed.
A fluid control method includes: generating, in a reaction chamber (84) formed between an outer cylinder (61) and an inner cylinder (70) coaxially disposed in the outer cylinder (61), a reaction phase (30) having a ring shape and formed of a reaction target fluid (F1, F2) in which a Taylor vortex (V1) is generated, the reaction phases (30) arranged in an axis (R) direction, and an inhibiting phase (31) having a ring shape that is adjacent to the reaction phase (30) in the axis (R) direction and inhibits the reaction target fluid (F1, F2) in the reaction phase (30) from flowing out to an outside of the reaction phase (30).
