\u0130nert gazla metal gaz gideriminin nedeni, eriyik i\u00e7ine \u00fcflenen inert gazda hidrojen bulunmamas\u0131 ve bu gaz\u0131n hidrojen k\u0131smi bas\u0131nc\u0131n\u0131n s\u0131f\u0131r olmas\u0131d\u0131r; buna kar\u015f\u0131n, kabarc\u0131klar\u0131n yak\u0131n\u0131ndaki eriyikteki hidrojen k\u0131smi bas\u0131nc\u0131 s\u0131f\u0131rdan \u00e7ok daha y\u00fcksektir.
