可ke以yi看kan到dao，信xin號hao路lu徑jing與yu回hui流liu路lu徑jing之zhi間jian的de互hu容rong遠yuan遠yuan大da於yu不bu同tong信xin號hao路lu徑jing之zhi間jian的de互hu容rong。我wo們men知zhi道dao，電dian容rong越yue大da阻zu抗kang越yue低di
，而er信xin號hao會hui選xuan擇ze低di阻zu抗kang的de路lu徑jing回hui流liu。所suo以yi更geng多duo的de能neng量liang耦ou合he到dao了le回hui流liu路lu徑jing上shang


，是shi的de，這zhe句ju話hua的de意yi思si是shi，信xin號hao的de回hui流liu與yu信xin號hao的de串chuan擾rao是shi同tong樣yang的de道dao理li，隻zhi不bu過guo能neng量liang在zai回hui流liu路lu徑jing上shang我wo們men叫jiao它ta回hui流liu並bing且qie去qu保bao護hu它ta，在zai其qi他ta信xin號hao上shang時shi我wo們men叫jiao他ta串chuan擾rao
，需xu要yao去qu避bi免mian它ta。當dang回hui流liu路lu徑jing阻zu抗kang很hen高gao時shi，信xin號hao可ke以yi通tong過guo附fu近jin的de其qi他ta信xin號hao進jin行xing回hui流liu，這zhe時shi串chuan擾rao就jiu非fei常chang非fei常chang高gao了le。
