中文摘要：

利用转移矩阵的方法研究双势阱中不同区域内波矢量之间的耦合机理，以更直观的图像，从新的角度解释和分析了能态分裂的特性和物理机理．研究结果表明：当势垒宽度较小时，电子容易遂穿到达另一势阱中；随着遂穿几率越大，波函数之间的耦合越强，能态的分裂越容易，反之波函数之间的耦合越弱，能态分裂越难．

英文摘要：

Based on the standard transfer matrix method, the coupling mechanism between wave vectors o{ different regions in double potential well has been investigated. From a new viewpoint, the physical mechanism and the characteristics of energy states splittings have been explained and analysed with straightforward representation. The results show that electrons easily pass through from potential well to another one when the barrier is narrow. The stronger coupled wave functions will induce the energy states splitting easier.
