347 347h bir bir ah
Sharraxaadda Gaaban:
347 iyo 347h waa labadaba fasalada birta birta ee balaaran ee lagu dejiyo Columbium (niobium) waxaana badanaa loo isticmaalaa codsiyada heerkulka sare. "H" ee 347h wuxuu u taagan yahay "kaarboon sare," oo muujinaya in ay leedahay waxa ka sarreeya kaarboon-ka-sare marka loo eego heerka 347 bir aan birta lahayn.
