这是一段模拟电荷法（scm)的matlab源程序，求解了超高压输电线路下方工频电场，仿真出了离地面1.5m处的二维电场模型，该程序经过验证，准确无误，谢谢。(This is a matlab source program of the simulated charge method (scm). It solves the power frequency electric field under the UHV transmission line and simulates the two-dimensional electric field model 1.5m above the ground. The program has been verified and is accurate. Thank you.)

根据深圳市出租车GPS数据所提供的信息，针对交通出行数据的空间分布特征，选取了4月18号这天的全天数据出租车载客后的行驶数据， 利用mtalab对数据的处理，筛选出出租车的起始点及拥堵的时段的行驶数据并通过kmeans聚类分析设定拥堵的标准，得到对于出租车在路段上的车速在小于2.15公里/小时的时候可以认为非常拥堵，拥堵的时段 5:00-7:00,12:00-14:00,19:00-21:00，非常拥堵的时间段为5:00-7:00，19:00-21:00。(analyse traffic jam status of the shenzhen city)
