本文的主要贡献在于，河床地势的影响被容入数值通量中，并且同时对河床地势采用连接面方法离散。

The main contribution is that the bottom topography effect is included in numerical fluxes and the bottom topography is discretized with an interface method in the same step.

当充入混合气体中氢气比例上升时，灯的功率和总光通量下降5～10％，灯的工作电压也下降。

If the krypton component of mixture gases is filled, the power and total luminous flux of compact fluorescent lamps will be reduced to be down 5- 10%, and the lamp voltage is also reduced too.
