In the paper,a fast image retrieval method based on the DCT domain and correlative feedback is presented,which aims at JPEG images and uses color layout descriptors in the MPEG7 standard. As the method only needs entropy decoding,the speed of extracting image features is improved and storage space saved. The experiment result shows that the method has a high retrieval speed and a good effect.

Due to the problems existing in simulation on physical model of fire, such as heavy calculation, high complexity and difficulty in real-time simulation, a new real-time simulation method was raised based on fluid model and GPU acceleration. This method, based on the physical characteristics of fire, such as incompressibility, low density and inviscid, used the fluid equations to calculate the properties of fire. Then by accelerating this method through GPU, the real-time simulation of fire was realized and a realistic effect was achieved.

One of these testing methods, eddy current, has been widely used for metal thickness measuring because of its good sensitivity, high test speed , non-contact and other advantage. The principle of eddy current testing is that, when the test coil is close to the metal conductor with alternating current, the eddy current would be inducing in the conductor, and correspongdingly, the eddy current would affect the original magnetic field, the result is the coils impedance and inducing voltage changed.

Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。

The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .

结果表明：养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大； pH下降与饲料系数高有关；溶解氧含量排水口比进水口低，但仍维持在饱和状态，与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式，无机氮和有机物含量有升高趋势，氨氮有下降的趋势，与养殖密度，投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降，与排水口流水速度慢，磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在，这与养殖场杀菌消毒等措施有关。
