1. The two types of relativistic situations are those where there is ( with no dissipation of energy ) ( a ) a positional displacement of a material object involving a resisting / assisting force ( such as gravity ), with no resulting motion ( the gravity case ), or ( b ) a change in relative speed of a material object due to acceleration by externally applied energy ( the speed case ).
2. The other groups that submitted bids today were : Marubeni Corp . with subsidiary Sithe Energies Inc .; Korea Electric Power Co .; Ilijan Power Corp ., a group led by Enron Power Corp .; Aboitiz Equity Ventures with Nichimen Corp . and Applied Energy Systems; Siemens AG with U . K .-based Powergen International; and Alsons Consolidated Resources Inc . with Tomen Corp . and Singapore Power Corp.
3. The House bill was said to prioritize " funding towards energy programs that encourage economic competitiveness and growth, " and programs that would " help advance the nation s goal of energy independence . " Republican Representative Rodney Frelinghuysen said that, " the reductions we had to make to the applied energy research and energy development programs will shift more of their work to the private sector . " Arguing in favor of his amendment to end spending on advertisements for renewal energy, Rep . Walberg said, " the American people don t need more government bureaucracy telling them what energy sources they should use, " and that " the government needs to get out of the business of picking winners and losers in the energy market, and certainly shouldn t be funding advertising campaigns on behalf of private green-energy firms ."
4. Alternatively, such devices as ion thrusters, while having a notably lower specific impulse, give a much better thrust-to-power ratio; for photons, that ratio is 1 / c, whereas for slow particles ( that is, nonrelativistic; even the output from typical ion thrusters counts ) the ratio is 2 / v, which is much larger ( since v \ ll c ) . ( This is in a sense an unfair comparison, since the photons must be " created " and other particles are merely " accelerated ", but nonetheless the impulses per carried mass and per applied energy & mdash; the practical quantities & mdash; are as given . ) The photonic rocket is thus wasteful when power and not mass is at a premium, or when enough mass can be saved through the use of a weaker power source that reaction mass can be included without penalty.
5. It's difficult to find applied energy in a sentence. 用applied energy造句挺難的
