The adsorption properties of hydrogen on the supported-metal surfaces are investigated using the Green function method within the framework of tight-bindingapproximation.
应用格林函数方法在紧束缚近似下研究了氢在担载金属表面的吸附性质。

As conducting polymers belong to the system of wide energy band, the SSH model in a state of tight-bindingapproximation is too crude.
由于导电高分子是宽能带体系;对于该体系来说,紧束缚近似下的SSH模型是过于粗糙的。
