为了提高线路绕击耐雷性能,笔者研究了高压输电线路绕击耐雷性能的分析方法,对考虑击距系数K和地面倾角θ后的电气几何模型,以杆塔中心线与大地交点作参考点,推导了最大击距的计算方法,同时探讨了最大击距不存在情形下击距系数K、避雷线保护角α、地面倾角θ的关系问题,论证了可以通过平衡K、α、θ的取值而有效提高线路绕击耐雷性能。

首先通过对人体4个生理参数和风力的分析,由牛顿第二定律建立了赛跑的最优速度模型与能量消耗模型;其次利用微分方程的解曲线与最优控制方法,结合普通极值与泛函极值方法,给出时间一定情况下的最大距离,以及赛跑距离一定情况下的最小时间,并利用最小二乘法对若干生理参数进行拟合估计;最后以某高校40多年男子赛跑成绩为依据进行模型检验,找出理论值与实际纪录值的相对误差,从而为提高赛跑成绩提供了科学依据。
