Ultraviolet Resonance Raman Spectra of Protein

Diffraction Properties of Field Adjustable Polymer Network Stabilized Liquid Crystal Grating

第九届全国发光学术会议

作者： E Shulin Laboratory of Excited State Processes Chinese Academy of Sciences Changchun, 130021

Ultraviolet Resonance Raman spectroscopy provides an excelleni tool for elucidating the structurefeatures of proteins. Until recently, light sources for obtaining Raman scattering from proteins have beenvisible lasers. Raman spectra of colorless proteins with visible laser excition consist of an overlap of bondsfrom vibrations of main chain and amino acid residues of about twenty kinds. Some of the Raman bonds of

Chinese Journal of Lasers 1999年第4期8卷 20-25页

作者： REN Hongwen LING Zhihua CHU Zhensheng * HUANG Ximin (North Liquid Crystal R & D Center, Changchun Institute of Physics, Chinese Academy of Sciences, Changchun 130021, China * EL Research Lab. Changchun Institute of Physics, Chinese Academy 中科院长春物理所吉林长春 130021 中科院长春物理所吉林长春

A new diffraction grating mode has been proposed. This grating is formed by applying of a spatially periodic electric field to a polymer network stabilized uniformly aligned liquid crystal layer. Due to the electro optic properties of the polymer network stabilized liquid crystal layer, the grating type is electrically adjustable, i.e. it presents amplitude, phase or amplitude phase type depending on the applied voltages. Experimental results show that the number of visible diffraction orders can be adjusted easily, and even be closed at the same time. The detail fabrication process and experimental results will be presented.

The copper (Cu) content in 205 soil samples (0–20 cm) of Tibet, covering 5 soil classes, were analyzed. The results showed as follows: (1) the average content of Cu was 19.6 mg kg-1 (CV=49. 28%); (2) the content of Cu in Tibetan soils was lower than the average level of China; (3) the content of Cu gradually decreased from the southeast to the northwest which was consistent with the direction of changes in the zonal successions of soil in Tibet; (4) Cu contents in Tibetan soils varied with soil properties, particularly soil parent materials that Cu contents were remarkably enriched in soils derived from shale materials.

作者： Hua Zhao (Department of Physiology,School of Basic Medical Sciences, Ji Lin University, Changchun 130021)

The morphological and physiological studies have indicated an important role for serotonin in the central mechanism of OSAS occurring. The reduction of 5-HT in the nuclei of raphe suppressed the activities of hypoglossal motor neurons during sleep ,then pharynx dilator muscle relaxed and resulted in OSAS at last. Habenular nucleus(Hb) located in thalamencephalon projected directly to the nuclei of raphe and influenced its functions. The expeirment aim is to investigate the regulating effect of Hb on the nuclei of raphe in OSAS and find the possiblly referred neurotransmitters or mediator. The results are stated as

Volcano eruption is one of the most serious geological disasters in the world. There are volcanoes in every territory on the earth, about a thousand in China, among which Changbai Mountain Volcano, Wudalianchi Volcano and Tengchong Volcano are the most latent catastrophic eruptive active volcanoes. The paper, following an instance of Changbai Mountain Volcano, expounds that monitoring, forecasting and estimating volcano disaster by building Volcano Disaster Information System (VDIS) is feasible to alleviate volcano disaster.
