本文总结了1960年以前H_(01)型渡波导传输方面的若干研究成果以及研究工作的若干问题(本文的内容只限于传输方面,没有包括终端设备、编码、译码、脉冲仪器等方面的研究成果)。 实验方面,采用谐振吸收方法测量了短波导及元件的小衰耗;采用微波短脉冲方法测量了波导实验线的衰耗。作为和上述方法的比较,同时采用比较法测波导衰减。(测量所得结果,与上述方法之结果基本一致)。得出了在3厘米和8毫米波段H_(01)型波的衰耗数据。 在波导实验线中,进行了在3厘米及8毫米波段多种通信方式(包括电话、电视、传真)的试验。试验结果表明:信号通过波导实验线的接头及转弯,没有发生显著失真。研究了非寻常不连续性所产生的传其图象的畸变。 理论方面,提出了多渡型波导本地正规波型的广义理论。提出了一个解决缓变参数多波型波导的数学方法。在螺旋波导计算中,采用了螺旋坐标系统对螺旋波导理论作了补充。 本文提出了波导传输的进一步研究方向问题。
This paper summarizes some research results of H_ (01) transitional waveguide transmission before 1960 and some problems in the research work. The content of this paper is limited to the transmission, and does not include the research of terminal equipment, coding, decoding, pulse instrumentation Results). In the experiment, the short-wave guide and the element’s small attenuation were measured by the resonance absorption method. The attenuation of the waveguide experimental line was measured by the microwave short pulse method. As a comparison with the above method, the attenuation of the waveguide is measured by the comparison method at the same time. (Measured results, and the results of the above method is basically the same). The attenuation data of H_ (01) -type waves at 3 cm and 8 mm were obtained. In the waveguide experimental line, experiments were conducted on various communication methods (including telephone, television, and fax) in the 3 cm and 8 mm bands. The experimental results show that no significant distortion occurs when the signal passes through the joints and turns of the waveguide experimental line. The aberration caused by the unusual discontinuity is studied. In theory, a generalized theory of transitional waveguides is proposed. A mathematical method to solve the slowly changing parameter multiwaveguide waveguide is proposed. In helical waveguide calculation, helical coordinate system is used to supplement spiral waveguide theory. This paper presents the further research directions of waveguide transmission.
