引入减阻剂后，可降低湍流磨擦阻力，提高流速。增大输送距离和提高管道输送能力。
The adding of the drag reduction agent can reduce the friction force of the current and increase the flow speed as well as increase the conveying distance.
由于流动接触可使起动磨擦阻力及动磨擦阻力为极小，因此可以节省能源，容易得到较高运动速度。
Can start the flow of contacts and dynamic friction resistance is to minimize the friction resistance, it can save energy, easy to get a higher velocity.
