Asymptotic freedom predicts that the interaction among quarks and gluons gets weaker at high energy, and the detailed theory enables physicists to make a fairly precise estimate of the temperature at which thermal motion is sufficient to rip quarks and antiquarks apart.  3, record 1, English, - thermal%20agitation

The ratio of the energy content of the fuel used to the electrical energy produced over a given period; it can be referred to the electricity generated(gross) or the electricity supplied(net). The reciprocal of the heat rate expressed as a percentage is the thermal efficiency of the power station. In the case of the "heat rate" the units should be stated; in the case of the "thermal efficiency" the energy content of the fuel and the electrical energy produced must be expressed in the same unit.  4, record 3, English, - heat%20rate

In respect of a boiler, "heat output" relates to the energy value of the useful hot water or steam produced. In considering electricity generation, however, the overall thermal efficiency is the total energy value of the electricity "sent out", expressed as a percentage of the energy value (gross as fired) of the fuel used. This overall concept takes account of both boiler and steam turbine losses. A modern power station achieves about 35 per cent thermal efficiency.  4, record 4, English, - thermal%20efficiency

Le perfectionnement des RHTRG [réacteurs à haute température refroidis par gaz] aura pour but d'améliorer la performance et de prolonger la durée de vie des centrales. Pour le premier point, de nombreuses recherches sont actuellement consacrées à ce que l'on appelle le cycle à turbine à gaz, où un gaz à haute température alimente directement une turbine à gaz ce qui permet d'obtenir un rendement thermique très élevé et un coût de l'énergie très intéressant ainsi qu'à la production de chaleur industrielle à très haute température.  2, record 4, French, - rendement%20thermique

Low energy gas(LEG) is produced by air gasification processes where a portion of the input wood(about 20 percent) is combusted with air to provide process heat. LEG can be used to displace fossil fuels by retrofitting oil or gas-fired boilers, kilns, dryers and space heaters. In addition, it can be cooled and cleaned for use in internal combustion engines to generate shaft power or electricity. Due to the low energy content, economics dictate that the gas be used immediately and not piped great distances.  1, record 5, English, - low%20energy%20gas
