摘　　要：自由空间法是一种非限制测试环境的测量方法,它能被应用于实验室测量或室外实地测量中。本文运用自由空间法测试水溶液的介电常数并将其与使用同轴探头法的测试结果进行比较,得出同轴探头法与自由空间法的测试结果基本吻合的结论,从而验证自由空间法的准确性和此测试系统的可行性。The free-space method is a non-restricted test environment measurement method which can be applied to laboratory measurements or outdoor field measurements. In this paper, we test the permittivity of aqueous solution by free space method and compare its results with the test using the coaxial probe method, and draw a conclusion that coaxial probe method and the free space of test results is consistent , thus verify the accuracy of free space method and feasibility of this test system.
