摘　　要：在基于B/S模式的电厂机组运行参数在线监测系统中,大量实时数据的动态图形绘制以及历史数据趋势图绘制一直是程序实现的难点。结合电厂的实际情况,文中提出一种利用矢量标记语言(VML)的解决方案,并给出了在ASP+VBScript+JAVAScipt+SQL Server环境下实现动态绘制矢量数据统计图形的实现方法及关键代码。In the on-line supervisory system of power station unit based on B/S mode for supervising the operational parameters, it is difficult for implementing the program to draw a large number of dynamic curves of real-time data and tendency charts of historical data, According to the practical situation of the power plant, a method to solve the problem is given by the use of VML（Veetor Markup Language） in the paper. The detailed technique and key codes to draft statistical chart of vector data dynamically in the environment of ASP＋VBSeript＋JAVASeipt＋SQL Server are provided.
