3.
This paper has made study on the experimental measuring, numerical simulation and theoretical derivation of swimming optimization, which includes details as following:Because of the difficulty in directly measuring the active drag in swimming, this paper designed a set of system-Additive Small Drag Method to measure it indirectly, which can be used as a training device also.
本文对游泳运动优化开展了实验测量、数值模拟和理论推导三方面的研究工作,具体内容包括:针对游泳运动中动态阻力直接测量的困难,研究并设计了一套间接测量—附加小扰阻法测量系统,该系统还可作为游泳训练设备使用。
补充资料：肺循环阻力(或全肺阻力)
肺循环阻力(或全肺阻力)
pulmonary circulation resistance
血液在肺部血管内流动时和血管壁之间的摩擦力和血液内部的摩擦阻力。肺动脉管壁较薄，分支短而管径大，故肺动脉的可扩性较大，对血流的阻力很小，仅0.12PRU(外周阻力单位)。肺循环动脉部分总的阻力和静脉部分总的阻力相等，故血液流动时在动脉部分的压力降落和静脉部分的压力降落相等。
