[ noun ] (physics,electricity) electrical conduction through a gas in an applied electric field
Synonyms Used in print (Raymond C. Binder et al., editors, Proceedings...)Experiments were made on an electric arc applying a porous graphite anode cooled by a transpiring gas ( Argon ) . Thus , the energy transferred from the arc to the anode was partly fed back into the arc . Thus , the energy transferred from the arc to the anode was partly fed back into the arc . It was shown that by proper anode design the net energy loss of the arc to the anode could be reduced to approximately 15 % of the total arc energy A detailed energy balance of the anode was established .

[ noun ] (mathematics,geometry) a continuous portion of a circle
Used in print (The New York Times,...)The ball went off in a majestic arc , an out-of-bounds slice . (R. P. Jerrard, "Inscribed squares in plane curves"...)But **f is just the curve **f translated without rotation through a small arc , for **f is always obtained by rotating C through exactly 90 ` . The arc is itself a segment of an analytic curve . A continuous change in t through an amount e results in a translation along an analytic arc of the curve **f . (Robert A. Futterman, The Future of Our Cities....)The drive along Massachusetts ' Route_128 , the by-pass which makes an arc about twenty miles from downtown Boston , may be a vision of the future . |
