The analytical expresses of scattering field are obtained based on the boundary condition of a sheath helix model. The effects of the pitch angle and the electrical size of the helix on the resonant behavior are also investigated. It is shown that the resonant behavior of the forward/back scattering far field only depends on the pitch electrical size and the radial electrical size, and that the turn of the helix has no effect on the resonant behavior.

根据sheath螺线管模型的边界条件获得了散射场的解析表达，同时研究了螺线管在共振状态下电角度及螺间距的影响，表明远场的前后向散射的共振状态只依赖于间隙的电场大小及径向的电场大小，而螺线管的倒转不影响谐振状态。

The rules of the cold-test characteristics changing with helix pitch are also studied and it turns out that, with increasing helix pitch, the phase velocity increases linearly, the interaction impedance changes nonlinearly and the attenuation constant decreases nonlinearly. At the same time, with the limitation of the synchronism between the electron beam and the electromagnetic wave, the change of pitch is small and therefore an approximate linear relation can be introduced.

研究表明：相速几乎随螺距增大而线性变大，互作用阻抗与螺距是非线性的关系，衰减常数随螺距增大而非线性地减小；由于在维持电子注与电磁波速度同步的限制下，螺距变化的幅度不可能很大，因此可近似按线性关系来处理互作用阻抗及衰减常数与螺距之间的关系。
