摘　　要：分段渐变型漏泄同轴电缆(漏缆)具有的特殊槽孔设计使其在始末端耦合损耗存在差异,保证了沿线的接收电平基本稳定,从而满足了5G通信等特殊场景对无线覆盖的新需求。为了能准确而便捷地对分段渐变型漏缆耦合损耗进行评估,以HLRHTCYZ-50-32(1-1/4″)分段渐变型漏缆为例,展开了相关评估方法的研究。通过对各评估方法所获实测数据的对比分析,建议分段渐变型漏缆在初步设计时采用各分段耦合损耗对数平均计算法对耦合损耗进行较为准确、便捷的评估,在设计定型时采用标准评估方法(即分段渐变型漏缆耦合损耗测试数据统计法)对耦合损耗进行准确、全面的评估。The special slot design of the leaky coaxial cable with segmentation gradients makes the coupling loss at the beginning and end different, and ensures the basic stability of the receiving level along the line, so as to meet the new requirements for wireless coverage in special scenarios such as 5 G communication. In order to evaluate the coupling loss of leaky coaxial cable with segmentation gradients accurately and conveniently, taking HLRHTCYZ-50-32(1-1/4″) leaky coaxial cable with segmentation gradients as an example, the relevant evaluation methods are studied. Through the comparative analysis of the measured data obtained by each evaluation method, it is suggested that the logarithmic mean value calculation method of coupling loss of each segmentation shall be used to evaluate the coupling loss more accurately and conveniently in the preliminary design of leaky coaxial cable with segmentation gradients, and the standard evaluation method(i.e. the statistical method of coupling loss test data of leaky coaxial cable with segmentation gradients) shall be used to evaluate the coupling loss accurately and comprehensively in the design finalization.
