测量游泳动态阻力的附加阻力微扰动法
2.
This paper gives a general introduction of several measurements of active drag in swimming:MAD method, velocity perturbation method, bioenergetic method, model method, towing method, etc.
本文介绍了几种游泳动态阻力的测试方法--MAD测试系统、速度扰动法、生物能量转换法、模型法和牵引法等。
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。
2) dynamic resistance
动态阻力,动态电阻
3) dynamicdrag
动力阻力
4) rotational resistance torque in depressed state
减压状态转动阻力矩
5) stiction
['stikʃən]
静态阻力
1.
There have been many experiments testing stiction on human bodies in swimming.
针对前人对游泳运动中静态阻力的研究都是根据试验测量来进行的,引入一种新的分析方法———计算流体力学法,通过该方法,先建立人体简化几何模型,然后计算不同来流速度条件下处于水平俯卧状态下人体模型所受到的阻力,即静态阻力,同时计算静态阻力系数,并与前人的实验结果做对比分析。
6) trim drag
航态阻力
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。
