gariiradda birta duuban ee duuban DC01 DC03 DC04 DC06
Iyada oo leh sawir aad u fiican iyo waxqabadka alxanka iyo saxnaanta cabbirka oo aad u sarreeya, clod-ka ayaa duubay kaarboonka hoose iyo taargooyinka birta aadka u hooseeya ee ay bixisay Mittel ayaa si weyn loogu dabaqay soo saaridda qaybaha baabuurta kala duwan. Iyada oo xoogaa duct ah, DC04 (St14, St15) kaarboon hooseeya iyo taargooyinka birta kaarboon ee aadka u hooseeya ayaa ku habboon sameynta fudud, foorarsiga ama alxanka.
