description	The invention discloses a liquid lubrication rotating shaft resistance reduction method based on Taylor vortex regulation and control, and belongs to the technical field of liquid lubrication rotatingshaft resistance reduction. According to the liquid lubrication rotating shaft resistance reduction method, by means of the retardation effect of the Taylor vortex under the Taylor-Couette flow situation, when a rotating shaft rotates, the circumferential flow of lubrication liquid between the rotating shaft and a shaft sleeve belongs to Taylor-Couette flow; by controlling the liquid level heightof the gap between the rotating shaft and the shaft sleeve in Taylor-Couette flow, the rotating speed of the rotating shaft and the injection speed of to-be-measured liquid are controlled, and the retardation effect, at different Reynolds numbers and different injection speeds, of the Taylor vortex is achieved; and by slowly increasing the liquid level height of the lubrication liquid between therotating shaft and the sha
