运用本征值法，经过详细的理论分析，提出一种新型的宽壁耦合器，它不需任何附加的阻抗匹配装置，实物测试结果表明其性能良好。

By using eigenvalue method,and exhausitive theoretical analysis, a new type of wide wall coupler is developed here,it does not need any additional impedance matching devices.From the result of full scale test,we can see the more satisfactory quality.
