摘　　要：以虚拟仪器软件开发环境LabWindows/CVI为开发平台,开发了用于风洞风速数据检测与分析的虚拟仪器系统,以利用可移动式风蚀风洞开展土壤风蚀的研究。系统具有数据采集、运算、分析、显示和存储等功能。经实验验证,其性能稳定可靠,操作方便,提高了风蚀风洞内风速和风廓特性检测分析的精度及自动化程度。In this paper, data detection of the wind velocity and analysis system for the wind - tunnel are established by using LabWindows/CVI as software developing environment in order to study on the soil wind erosion. It can carry on data acquisition ,value operation ,data analysis ,displaying and collecting data and so on. The performance of the system was studied and tested, and the result indicated that it worked well and operated conveniently. It had higher automatic extent and higher test precision for the wind velocity of the wind erosion wind - tunnel. In addition, it could also describe well the character of the wind velocity profile to data which was acquired by the software.
