Because of thermal inertia, the time at which it reaches its maximum temperature comes somewhat after local "noon", a phenomenon that any sunbather will recognise.
由于热惯性，当温度达到最高时常在“正午”偏后，日光浴者深知这一现象。

The efficiency of a coal-fired thermal plant is typically in the range of 30%-35%. In a combined cycle gas turbine system running on natural gas, the maximum efficiency is in the range 45%-50%.
The altitude of an air burst can be varied to obtain maximum blast effects, maximumthermal effects, desired radiation effects, or a balanced combination of these effects.
