Absorption characteristics of de-pigmented particle and yellow substance in Bohai Sea;

The analysis of Water Color Element Absorb Spectral Characteristic in Qinghai Lake ——Yellow substance,De-pigment particles and phytoplankton pigments;

Effects of photoresponses on the movement of pigment granule in erythrophores of Xiphophorus helleri and the mechanism;

The ultrastructural observation of the cultured cells at 4, 15, 25, 35, 45 days by electronic microscope show that pigment granules were the most in the cultured cells of 15 days plus promoter Cu 2+ , and there are not pigment granules in the cultured cells of 4 days or plus restrainer 2,4 D.

Using tadpoles of Rana chensinensis as experimental animal, we detected the effects of illumination and concentration of melatonin on tadpole melanin granule clustering degree, at head trigone, basal of tail muscle, tail basal ogami fins, cental of tail muscle, tail central ogami fins and tail tip, in order to explore the term using tadpoles to test melatonin at quantitative.

Objective To evaluate the filtration efficiency of different types of mask filtration materials against non-biological particles aerosol and microbial aerosol.
