It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The analytical relations for determination of cathode surface field-emission parameters of field amplification factor /spl beta/ and work function /spl phi/ from experiments of vacuum breakdown delay time have been obtained. Field amplification factor is shown to take minimal value /spl beta/=1 at critical electrical field E/sub /spl sigma//=1.32/spl times/10/sup 10/ V/m. Vacuum breakdown delay time corresponding to critical field is determined by cathode material physical constants.
