摘　　要：拉压力传感器、位移传感器、压力传感器这三种传感器在进行组合选型时,需要确定备选方案中的容量、匹配性能、精度、反应速度、适应性、成本六项选型评价指标的关联度。为使选型方案具有更高的性价比,采用将可拓学理论应用于传感器选型评价中。结果表明,利用可拓学理论对传感器进行选型评价具有较好的实用性和有效性。In combined model selection for tension transducer, displacement transducer, and pressure transducer, it is necessary to determine the interrelation degree among six model selection evaluation indexes, including capacity, compatible performance, accuracy, response speed, adaptability, and cost. In order to make high cost-effectiveness for model selection strategy, the expandability theory is used in evaluation of model selection. The result indicates that by using expendability theory, the effectiveness and functionality of the evaluation are better.
