| Abstract: | On the basis of the results of quantizations of lattice vibrations of staff in nano mechine and Micro mechine, formulas for the energy and specific heat of lattice vibrations are deduced, and numerical calculations are carried out with technique of neural network. It is found that the energy of lattice vibrations increases, and the specific heat decreases when the size of staff in nano mechine and micro mechine increase. |
