A brief review for ecological studies on hyporheic zone of stream ecosystem;

A preliminary study on the assessment of stream ecosystem health in south of Anhui Province using Benthic-Index of Biotic Integrity;

Seasonal dynamics of hydrochemical characteristics of streams under different forest types.;

In this paper the evolutionary process of fluid flow regimes of the retained oil displaced by bio-surfactants after water flooding was presented in laboratory test as follows: partial protuberance,growth in length,prolongation to oil silk;fracture of the oil silk,quick retraction to small oil particles;movement to the well bottom after their coalescence to large particles,oil wall.

A model installation of SBD was designed and set for the measurement of fluid flow regimes.

Plastic flow pattern and test analysis in friction stir welding;

Mechanism of flow pattern affected by corrugation geometric parameters in the chevron-type plate heat exchanger;

Based on experiments,this article sets out to prove that the difference in Reynolds value,on which fluids'flow patterns are decided,results from variations in experimental devices and conditions.

Flow morphology and mechanism ofpattern formation was given and discussed for thin-walled casting during anti-gravity mould fillig.
