Cov Ntsiab Lus Tseem Ceeb: Koj yog qhov yuav tiag tiag
Hla - lub sij hawm vs doppler
Hloov pauv {- lub sijhawm meters xa suab ob txoj kev los ntawm kev ntws. Suab caij nrog cov txaus tuaj sai dua li lub suab tawm tsam nws. Lub meter lub sij hawm hloov lub sijhawm sib txawv rau hauv kev tshaj tawm thiab khoo los ntawm cov yeeb nkab thaj chaw. Cov meters zoo li cov dej huv. Doppler meters mloog echoes los ntawm npuas lossis cov khib nyiab; Lawv haum rau dej lossis qias neeg.
Txoj kev suav
