为便于加工，以往的吉赫兹横电磁波传输室(GTEM Cell)过渡接头中斧形过渡块均采用近似设计，即侧边取直线。这样做的结果是传输损耗曲线在过渡段的分布不理想。基于修正的目的，首次给出了精确的斧形块侧边之连续曲线方程。

To be convenient for machining, the conventional axe-shaped pieces were approximately designed. It is proved that the traditional transition in a GTEM Cell can not give a satisfactory transmission loss distribution. So this paper gives the exact continuous curve equation for the axe-shaped piece´s two sides for the first time.
