The performances of the PEMFC were evaluated without external humidification for the reactant gases when the hydrogen and the oxygen were in co flow or in counter flow.

Study on Humidification Treatment in Particleboard Mat Surface;

Research on self-humidification of PEMFC;

Study on Temperature Decreasing and Humidification of Ornamental Plants in Shanghai;

On this basis, the method of distortion correction by means of wetting to form local softening is suggested.

The influential regularity of wetting and inherent anisotropic on the loess dynamic shear modulus is obtained.

Analysis of shear strength characteristics of loess during moistening process;

The main reason that makes tunnel surrounding loess unstable is excavation -disturbance and moistening in loess.

In order to investigate the relationship among stress,strain and strength of soil under unsaturated moistening,water content is introduced into the hardening parameter of Tsinghua model to develop the Tsinghua elastoplastic model of unsaturated soil.

Analysis of decreasing temperature and increasing humidity effect in different landscape models at scenic belt along the Grand Canal in Yangzhou;

The effect of decreasing temperature and increasing humidity of Syzygium cumini+ Cinnamomum burmannii belt at the Baiyun Mountain National Scenic Area,Guangzhou was observed in summer holiday,the results were: the average daytime light intensity of the plot that was 2 meters long from the S.
