The 4 Mw biomass gasification referral circle power generation system developed by the Chinese Academy of Sciences Guangzhou Institute of Energy take husk, wood chips, straw and other biomass wastes for raw materials, its power generation efficiency is up to 20% ~ 28%, it can meet the rural agricultural waste handling needs.
Near term focus of China's bio-liquid fuel technology research and development direction is the use of non-food raw materials (mainly sweet sorghum, cassava and wood cellulose, etc.) of fuel ethanol production technology, as well as biodiesel technology of using Jatropha curcas and other oil crops as raw materials, and construction of large-scale raw material supply base and the establishment of biomass liquid fuel processing enterprises.
At present, the small-scale experiments of fuel ethanol based sweet sorghum and cassava and biodiesel taken jatropha as raw materials have been carried out, they accumulated experience for our large-scale development and utilization of bio-liquid fuel.
At the same time, some of our companies are researching and developing bio-liquid fuel technology taken straw, wood and other non-food for raw materials, and have made some breakthroughs, the large-scale production capacity are expected in 2012 about.

The design and construction of the SODIS system require transparent materials that allow sunlight to penetrate through its surface layer to decontaminate water from pathogens.
However, not all transparent materials have suitable properties for SODIS construction because solar water disinfection systems operate in sunny weather conditions that can quickly degrade non-UV-resistant materials.
Each SODIS reactor was made with the following materials; (a) 45o angled two-dimensional 0.5 mm thick highly reflective CPC mirrors were built from aluminium sheets to concentrate solar UV radiation and distribute it equally on the SODIS tube.
Cement, aggregate, binding wire, river sand, and formwork (blockboard, 2x2 timbers, wire nails, and used oil) were critical construction materials for building the plinths at both sites.
The fencing materials for both sites were 75 mm corner posts, 40 mm diamond mesh, razor wire, cutting disc, red oxide, welding rods, 4 mm galvanised wire, and 1 mm galvanised wire.

Keywords: box girder with corrugated steel webs; cable stayed bridge; deflection; stress; strain
Abstract.
Compared with box girder bridge with concrete webs, box girder bridge with corrugated steel webs has many advantages such as lighter weight, higher prestressed transfer efficiency, higher material utilization, quicker construction and good-looking appearance etc[1].
All materials were assumed isotropic, all calculations only considered the elastic stage.

concrete mixing quality, the material feed rate and residual rate, which was the major target to be
optimal designing.
