Using the identification quantity to identify the long ear disfigurement was brought up, and by calculation, it can be found that identification quantity should be set as the quantity of long ear disfigurement of the position which is about 0. 2 times of plate width to the plate border. Conception of plate head tiny cell was brought up, and the long ear disfigurement was uncoupled into the product of elongation percentage and length of tiny cell. On the basis of prediction of long ear disfigurement, process control model of MAS rolling was built up, and application indicates that it can fit the on-line production and eliminate the long ear disfigurement commendably.

The processing conditions of the texture formation and deep drawability of a Ti-IF steel strip hot-rolled in ferritic region and subsequently annealed were investigated. The r-value increases with the decrease of reheating temperature, and finish rolling temperature and the increase of reductions in ferritic region. For lubricated ferritic rolling and annealing, the r-value is raised up to 1.75, and elongation rate is over 50% at the finish rolling temperature of 650 ℃, which is suitable for DDQ grade products. However, the r-value is below 1.0 in the case of unlubricated rolling. The X-ray diffraction was used to analyze the textural characteristic of samples. For samples subjected to lubricated rolling and annealing, the strong { 111 }//ND recrystallization texture is distributed homogeneously along the thickness direction, and the intensity of { 110} recrystallization texture is very low even in surface. However, for unlubricated samples, the {111} texture is distributed inhomogeneously and is weak along the thickness direction, and （110}//ND recrystallization texture is strong, which deteriorates the formability.

The plan view pattern control theoretical models were simplified. Under the condition of constant volume for the plan view pattern compensation, the relation between the thickness and the length can be simplified to the linearity in the segment for the plan view pattern control function. The compensation volume can be dispersed for easy calculation. By comparing the model calculation result with the actual result, it was concluded that the simplified model can be used for the online control process.

The forward slip model with adhesion was used to derive the formula of calculating taper rolling time. The relation between the rolling time and the taper length and the relation between the rolling time and the taper thickness can be obtained. The numerical solution for this formula was used on site. According to the simulation result, the roll gap value should be changed linearly with rolling time.

The rapid detection of pathogenic bacteria is vital for the prevention of outbreaks of infectious diseases, including infections by the common foodborne bacteria *** and Salmonella Carbohydrate microarrays have been developed as a powerful method to investigate carbohydrate-protein interaction with only very small amounts of glycans, which show great potential for detect the carbohydrate mediated interaction with pathogens. Here, different mannose-coated microarrays were constructed and tested with ***(K-12 and BL-21) and Salmonella enterica strains(ATCC9184 and ATCC31685) exhibiting different mannose binding affinities. The optimized carbohydrate microarray was then applied to test the binding of 12 Salmonella enterica and 9 *** isolates from local patients for the first time and showed strong binding with certain serovars or subtypes. The results showed that microarray probed with the single mannose structure is not enough for the detection of bacteria with various serovars or subtypes, which contain a high degree of allelic variation in adhesin. We suggest that a complex carbohydrate microarray containing different glycan conformation may be needed for detection of different bacteria isolates.

文化领域历来是各界关注和研究的重点。由于文化的内涵十分丰富,所以在其研究视角、发展规律、作用方式等方面存在着复杂性和多样性等特点,呈现出一种横看成岭侧成峰、远近高低各不同的情况。相对于从经济学和社会学角度来看待文化力,从权力的角度出发去研究文化力的意义以及作用方式,或可有不同的收获。其一,在权力体系内,文化力中各元素所发挥的作用难以替代,权力可以通过文化力来实现通过暴力难以达成的目标。其二,处在权力体系内的文化力对各文化元素的运用具有独特的特点。对这些特点进行研究和把握,有助于当前的社会主义文化建设。
