R. china

During preparation of multilayer films, interracial diffusion critically affects film performance. In this report, SrBiTaO (SBT) thin films were prepared on Pt/TiO/SiO/Si substrates using metalorganic decomposition spin-on technique. Impact of different heat treatment processing, film thickness, top electrode postanneal and atmosphere anneal on interfacial diffusion has been investigated by X-ray diffraction (XRD),

PCR amplification employing a SCAR (Sequence Characterized Amplified Region) primer pair, 135F/R,(amplifying a band of 601 bp) for identifying '135' strains of Lentinula dodes was used to establish the distribution of the specific SCAR marker among 58 protoplast monokaryons and 97 spore monokaryons isolated from a *** 135 *** *** segregated into either A1B1 or A2B2 mating type,and the SCAR marker was detected only in the *** marker was also detected in four delineated mating types (A1B1,A2B2,A1B2,A2B1) of spore *** data testify to the stable inheritance of the specific SCAR marker,and show that the SCAR locus is not genetically linked to either the A or B mating factors.

A large-scale pig farms in Jiangxi Province was researched ,a model of resource utilization for breeding wastewater was established with methane tank →clarifier →reservoir breeding →farmland irrigation. The results showed that the concentrations of COD, ammonia nitrogen and total phosphorus of the treated wastewater were 59.13mg/L,1.15mg/L and 0.015mg/L respectively , the degradation rates of which were 24.2%,99.34%,93.85% separately. The fish bait of reservoir for fish culture was saved by discharging certain concentration wastewater into it while the organic matter in the aquiculture wastewater was degraded by ecosystem. The reservoir water was used later as irrigation water and organic matter in the aquiculture wastewater was degraded thoroughly, which decreased the cost of discharging sewage from farms, eliminating pig emission pollution to the environment and increasing crop yields. The above model was an ecomodel, not only treating cultivating wastewater but also recycling the waste water. The management of piggery wastewater and monitoring of reservoir water quality were suggested in order to avoid water eutrophication.

1 general situation of CWM manufacture technology As a result of higher and higher international oil price and requirement of environment protection,Coal water Mixture (CWM),a new coal-based fuel,will be used widely in china. Up to 2005,the total production capacity of CWM has reached 12 million tons/a (not include gasification CWM). More than 30 CWM plants have been put into operation that CWM production capacity above 30000 t/a. CWM manufacture process is the core of CWM technology. Ideal CWM manufacture process is very important such as improvement the CWM quality and reducing production cost.
