The results show that the turbulence intensity, fouling cleaning intensity and pressure drop increase with the increase of flow velocity, particle size and the volume fraction. The effect of liquid-solid fluidzed-bed cleaning fouling depends on the reasonable combination of flow velocity, particle size and the volume fraction. Through an integral consideration of water saving and energy saving and uniformity of fouling cleaning, the optimum flow velocity of flow, particle size and volume fraction are 2.0 m/s~2.5 m/s, 3 mm~4 mm and of 5%~8 vol%, respectively.

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.

In the numerous extension patterns, the government leading extension pattern is the strongest, quicker, and the extension area is larger, but the extension system should be further strengthened, and the policy supports should be given by the government. The extension pattern with the research institutes as the main body is strict and scientific, and is welcomed by the peasants, but the extension strength is weak. The extension pattern with the companies as the main body has the advantage in the extension area, and is a new pattern, but the service consciousness of the agricultural fertilization should be strengthened. The extension pattern with the supply and marketing cooperative as the main body has the advantage of retailing fertilizers, but the technical training to the vocational staff should be strengthened. In the extension pattern with the chain radiation as the main body, the activity of the peasants is higher.

It was found that ARA was composed of esterification products of (2-HEA)-ester with pimaric acid, dehydroabietic acid, abietic acid and two isomers of acrylpimaric acid. ARA is a good crosslinking agent which can copolymerize with most vinyl monomers. The properties of solvent-resistance and heat resistance of the copolymer were improved considerably by the use of ARA.

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.
