[Effects of temperature on the ultraviolet absorption characteristics of SO2].

Absorption spectrum of SO2 is obtained under the condition of room temperature and atmosphere pressure. The spectrum is composed of banded structure superimposed on a continuum. The continuum structure comes from the transition of SO2 molecule from the ground electronic state to the higher dense rovibronic energy levels, and the banded one comes from the transition of B1B1<--X1A1.

[Theoretical study of 1+2+1 double-resonance multiphoton ionization probability].

The technique of resonance enhanced multiphoton ionization (REMPI) spectroscopy has already become an important method for studying the energy level structure of atoms and molecules. Analytic expression of 1+2+1 double REMPI probability of four-level system has been deduced with the theory of rate equation. Based on the expression, the present paper simulated the variations of ionization probability versus laser intensity, laser pulse duration and collision relaxation rate.

Clinical significance of annexin II expression in human non-small cell lung cancer.

The aim of the present study is to explore the role of annexin II in the development and progression of human non-small cell lung cancer (NSCLC). Real-time quantitative reverse transcription-polymerase chain reaction was conducted to detect annexin II mRNA expression. Annexin II protein expression was also determined by western blot.
