In this paper a newly develoed helical coordinates is used to make out the solution of electromagnetic fields in the helix gap and calculate dispersion characteristics of tape helix slow wave structure for the first time. strict boundary conditions for magnetic fields are adopted and are treated rigorously by fourier expansion. besides, the radial propagation constant of every layer in the dielectric - loaded region is differentiated. some of practical tape helix slow wave structures have been calculated for dispersion characteristics and the calculated values accord with measured values very well. the authors also compare the calculated results with experiments for different structures by changing tape thickness or other structure parameters and find that the theory in the paper is universal
本文首次運用螺旋坐標系給出了帶狀螺旋線縫隙內的電磁場解，並據此計算了帶狀螺旋慢波結構的色散特性.文中採用了嚴格的邊界條件，並以傅立葉展開進行了嚴格的數學處理.另外還首次對有介質區域內各層的徑向傳輸系數作了區別.本文使用這種方法計算了我們已研製的一些寬帶高功率行波管所用的慢波線結構的色散特性，理論與實驗符合得很好.我們還計算了不同結構參數對色散特性的影響，並與實驗作了對照，發現本文的理論有一定的普適性 -

In order to fully develop the theory of squeezed branch piles, in particular, the justification of its superior performance in terms of the bearing capacity and sinking displacement, we have derived the analytical formulas of the axial load and the strain at arbitrary depth ; based on existing static loading test results and research on belled pile, together with the analysis of on - site testing data, we have applied the expand theory on sphere holes to the computation of radial stress of squeezed branch piles under hole expansion ; taking the oil pressure of hole expansion in to account, we have find the a branch force under certain hole pressures, hence we can estimate the maximum bearing capacity of single piles ; we have introduced the experiential formulas for the bearing capacity of squeezed branch piles based on its stress characteristic and pile testing data ; we have also done numerical simulations of squeezed branch piles utilizing finite element method software ansys ; we have matched the simulation res ults with those of on - site basic load experiments, regenerating the distributions of stress fields and strain fields of squeezed branch piles, and from those distributions, we can determine the optimal distances between plates and piles
