Theoretical investigation on the fermi resonance effect in molecular vibronic spectra;

Amendment to bertran equation and the weak Fermi resonance characteristic of CS_2 in C_6H_6

The infra-red spectrogram of methacryloyl chloride was compared with acryloyl chloride and benzoyl chloride and found that 1765cm~(-1) and 1736cm~(-1) is the double peak produced form Fermi sympathetic vibration between the peak of v_(c=o)and 878.

The infra-red spectrogram of methacryloyl chloride was compared with acryloyl chloride and benzoyl chloride,the result showed that 1765cm~(-1) and 1736cm~(-1) were the double peak produced form Fermi sympathetic vibration between the peak of v_.

This paper analysises and researches into normal and abnormal Bose oscillators and normal and abnormal Fermi oscillators, respectively.

Eliminating acoustic resonance in metal halide lamps based on saber simulation;

;Applying axial magnetic field on low power metal halide lamps, its effects on acoustic resonance were observed experimentally.

Aimed at the characters of solar energy electronic ballast and the lack of HPS with high frequency,the paper describes a new high pressure sodium lamp based on the half bridge driver SG3525A,one kind of cheap chip,which adopted the variable frequency technology to avoid acoustic resonance.
