It demonstrated that the molecular size matching and the sterically arrangement of groups of studied compounds with nucleoside phosphates are very important for the interaction of them. And the quenching ability depends on the interaction of these species strongly. Evidently, this phenomenon can be used as a method for the molecular recognition of nucleoside phosphate by the changing of fluorescence intensity of these compounds.

Test results show that (1) the failure modes of the strengthened beams at high temperature can be classified as a flexure failure mode and a flexure-shear one;(2) the flexure failure of the strengthened beams at room temperature may change at high temperature;(3) as compared with the unstrengthened beam, the strengthened beams with higher load are of stronger fire resistance due to the existence of fire coating; and (4) the increase of the strengthening ratio may result in the improvement of fire resistance and the change of failure mode.

结果表明:高温下该类构件的破坏形态大致可分为受弯破坏和弯剪破坏两类,常温下发生弯曲破坏的加固构件有可能在高温下出现破坏形态的转变;虽然加固构件所承受的荷载明显大于未加固构件,但由于防火涂料的保护,其耐火极限仍大于后者;碳纤维布加固量增加有可能导致加固构件的耐火极限延长,同时还可能涉及破坏形态的转变。

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.
