Based on these, the electron-hole overlap functions and the energy shifts of excitons corresponding to different subbands are obtained, they agree well with experimental results.

The heat capacity of fuel varies as the fuel temperature, as well as pulse peak power and energy released can be increased by increasing heat capacity of the fuel.

In this paper, we start from the energy point of view, use AM-FM modulation model and formant frequency, to remove the vocalic interference which vast majority of energy in the useful speech.
