| 摘 要： | 利用经过截取处理的欧亚范围的欧洲格点数据，通过运算转化为屏幕网格资料，采用逐点追踪方法绘制等压线，运用统计识别法和模糊识别技术，结合实测风场订正，对高低压中心和槽线进行分析识别。试验结果表明，计算机能基本准确的识别出高低压中心及槽线，且速度比人工快得多，从而可做为人工智能工作站的一相接口，并为天气图的客观化和自动化分析作了初步尝试。

| Abstract: | urope-Asia regional grid data is prepared and convered into computer screen grid data. By calculation,contour lines are drawn up. And then,high pressure centres and low pressure centres and trough-lines are determined with statistical recognition and fuzzy recognition technology,and reduced with wind observation. Test suggests that a connection of artificial intelligence work station could be made. |

| Keywords: | pattern recognition high and low pressure centre trough-line |
