Xa Ib Tsab EmailCov xov tooj liab concentric yog tsim rau ntau yam kev siv, suav nrog qhov nkag mus rau kev pabcuam fais fab, cov xov hlau pub mov, thiab siv rau hauv thaj chaw ntub lossis qhuav, thiab tuaj yeem tso ncaj qha rau hauv av. Cov xov hlau concentric feem ntau yog siv los ntawm cov neeg ua haujlwm faib khoom siv txuas cov tes hauj lwm hluav taws xob thiab cov pej thuam mus rau lub tsev lossis lag luam ntawm tus neeg. Haum rau kev faus ncaj qha, lawv kuj tseem siv rau cov chaw tseem ceeb hauv cov pej thuam siab thiab cov kab ke teeb pom kev zoo ntawm txoj kev.
Rau kev sib txuas rau lub network overhead, ntsia nruab nrab ntawmlub network faib khoom siv theem obrau txhua tus neeg siv 'meter'. Nws yog siv tshwj xeeb los tiv thaiv kev nyiag hluav taws xob. Kub ua haujlwm: 75 ° C lossis 90 ° C.
