| 摘 要： | 为了揭示气温、气压和海拔高度对自行车运动阻力的影响,采用力学模型计算的方法,通过设定的气温、气压和海拔高度计算空气密度,估算自行车运动阻力。研究表明:在其他条件不变的情况下,随着气温的升高,自行车运动阻力减小;随着气压的升高,自行车运动阻力增大;随着海拔高度的升高,自行车运动阻力减小。

| Abstract: | In order to discover the influence of temperature,barometric pressure and elevation upon the resistance for cycling,the mechanic model method is used in this paper to estimate the resistance for cycling and air density by setting temperature,barometric pressure and elevation.The study shows that when other conditions remain the same,with the going-up of temperature,the resistance for cycling reduces;with the going-up of barometric pressure,the resistance for cycling increases;and with the going-up of elevation height,the resistance for cycling reduces. |
