The theory of wilkinson power combiner and ratrace coupler is analyzed by using the odd - even mode method in this thesis. on the basis of the theoretical analysis, we designed and tested the wilkinson power divider, the modified wilkinson power divider and ratrace coupler, good agreement is observed. in addition we propose a power combiner based on a waveguide - to - microstrip transition using antipodal finlines. this structure united the two functions of transition and equal power division, it can not only be used in the circuit power combiner but also be used in spatial power combiner
另外提出一種基於鰭線波導微帶過渡功分器，該結構將過渡與功分兩種功能完全結合，不但可以用於電路合成式功率合成，也可用於空間功率合成中。對功率合成器，其主要指標是輸出功率和效率，其中提高輸出功率和效率的一個方法是在輸出端抑制諧波，主要是對二次諧波的抑制。 -

在分析偶數階歸一化累積量演算法的基礎上，提出了奇數階（三、二階和五、二階）歸一化累積量演算法，論證並推導出一種新的盲均衡準則，最後利用最速下降法形成了新演算法。 -
In the part of discussion, the suitability of the jacobi elliptic function expansion method is also studied by proposing the " rank ". and we firstly point out that when the " ranks " of every term of the nonlinear evolution equation are simultaneously even or odd, the method can be used to solve the equation
為了討論了jacobi橢圓函數展開法的適用性問題，我們最先引進「秩」的概念，指出只要非線性發展方程的各項的「秩」滿足相同的奇偶性，就可以用這種展開法求解。 -
Then the explicit finite - volume method for the two - dimensional steady navier - stocks equations is studied. in order to prevent odd - even decoupling of the solution and oscillations near the shock waves, artificial dissipation is added. local time step, residue averaging, enthalpy damping and multi - grid method are used to accelerate the convergence during the five - step runge - kutta explicit time marching
