摘　　要：对Surfer软件功能深入研究发现,Surfer与Vb编程语言之间可以实现ActiveX自动化连接,将Surfer强大的绘图功能与Vb编制交互界面程序的优势相结合,通过Vb调用Surfer的绘图函数,实现加密自动雨量资料的填图、等值线绘图及色彩填充,并能动态地显示与输出这些图形。将自动雨量图与火箭作业点图层叠加,并嵌入到人影业务系统中,可及时、准确地了解作业点附近及其上游的降雨情况,为选择合适时机和地点实施人工增雨作业提供参考。此方法也为今后开发具有绘图功能的业务系统提供了一个可参考的方向。By means of powerful capability of Surfer, in combination with Vb programming language, the ActiveX link can be set up. Calling the plotting functions of Surfer by Vb, the spotting, isoline plotting, and color filling of the town-level rainfall charts are realized automatically, as well as their dynamic display and export. The resulting rain charts can be overlapped with the rainfall enhancement operation sites, which can be embed into rain enhancement operating systems to provide useful reference for the determination of the appropriate operation time. The method can be also applied to other operational systems needing automatic plotting.
