Qib Kev Qhia: PSL1, PSL2

PSL (Qib Khoom Qhia Txog Khoom) yog muab faib ua PSL1 thiab PSL2, thiab tuaj yeem nkag siab tias yog cov qib zoo sib txawv.

Ob qho no tsis yog tsuas yog txawv ntawm qhov yuav tsum tau tshuaj xyuas xwb, tab sis kuj tseem muaj cov tshuaj lom neeg sib xyaw thiab kev ua haujlwm ntawm lub tshuab. Zuag qhia tag nrho, PSL2 siv cov kev tswj hwm nruj dua kom ua tau raws li cov xwm txheej kev pabcuam uas xav tau ntau dua.

Kev Ntsuas Kev Cuam Tshuam: Tsis tas yuav tsum muaj rau PSL1; yuav tsum muaj rau PSL2 (tshwj tsis yog X80 hauv qee kis)
Kev Ntsuas Tsis Ua Rau Puas Tsuaj (NDT): Tsis tas yuav tsum muaj rau PSL1; yuav tsum muaj rau PSL2

Cov txheej txheem NDT xws li kev kuaj ultrasonic lossis radiographic yog siv los nrhiav cov qhov tsis zoo sab hauv thiab xyuas kom meej tias cov khoom siv ruaj khov yam tsis ua rau cov yeeb nkab puas tsuaj.
