摘要：
A pyramid approach for remote sensing image registration based on mutual information and grey relational analysis is presented. The methodology applies edge information of image extracted using grey relational analysis and combines with mutual information regarding as similarity measure. First, the image pyramid is constructed by wavelet transform, and then coarse-to-fine multi-resolution search approaches have been put forward to increase accuracy and efficiency. An exhaustive search algorithm is applied at the coarsest level of the image pyramid. Registration at higher levels can be performed with the result at the pervious level serving as the initial condition. The effective and exact matching results can be obtained by applying the algorithm to remote sensing image registration.

Casing damage during water injection pressure relief is difficult to resolve in oil field. The fluid pressure of inner casing wall undergoes a sudden decrease because of injecting water release. At the same time, the effective stress of soil around the well-bore increases quickly, and the extrusion pressure of casing bearing also increases. In order to study the mechanism of the problem, a fluid-solid coupled model was set up. According to comparison of the fundamental equation and boundary conditions, the ANSYS function of temperature field analysis is similar to that of seepage flow field. The coupled analysis of strata-casing-cement system was done. The simulation results show that during the pressure relief process, the geo-stress around well-bore changes, at the beginning time the extrusion pressure increase suddenly, and then with the time going on, the pressure will be the same to the pore pressure of reservoirs. The bigger the pressure difference between inner wall and ektexine, the bigger extrusion pressure of casing bearing during the pressure relief.

摘要：
N-carbamylglutamate (NCG) and arginine were investigated with their effects on growth performance and maintain intestinal health in early-weaned piglets. Eighty-nine Landrace×Yorkshire piglets from 12 pens (average pen weight 5.56±0.51 kg; weaned at 21 d) were grouped into 3 treatment groups and fed one of the following diets for 7 days: a standard diet (SD), SD+NCG (0.08％), or SD+Arg (0.6％). Six piglets were randomly selected from each group and slaughtered. Compared with the control group, NCG and Arg each significantly increased ADG and ADFI (P<0.05). The incidence of diarrhea in the NCG group was lower (P<0.01) than those in the control and Arg groups (18.13 and 12.52％, respectively). Both NCG and Arg significantly increased the average intestine weight (P<0.05). Based on a comparison with the control group, the addition of Arg to the diet resulted in a greater villus height (P<0.05) in the duodenum and jejunum. Piglets fed NCG showed a similar trend in villus height. Goblet cell counts significantly increased in the ileum (P<0.05) in response to supplementation with Arg. NCG and Arg significantly increased serum Arg (P=0.028) and Ornithine (P=0.022) comparing to the control group. Serum citrulline increased 33.60 and 39.72％ in the NCG and Arg groups (P=0.221), respectively. Accordingly, serum NO tended to increase (P>0.05), and iNOS significantly increased (P<0.05) in the NCG group. NO in intestinal mucosa significantly increased in the Arg group (P=0.044), as well as in the NCG group (P>0.05). Real-time PCR showed that the expression of HSP70 mRNA was higher in ileum mucosa in the Arg and NCG groups (P<0.05). These results indicated that dietary supplementation with 0.08％ NCG or 0.6％ Arg could improve growth performance, stimulate intestinal growth and prevent intestinal mucosa dysfunction in weaned piglets. These findings indicate that NCG is a functional ingredient for weaning piglet in terms of supporting endogenous Arg synthesis, and may be able to more effectively alleviate weaning stress through an Arg-NO-HSP70 pathway than L-Arg.
摘要：
Based on sealing coring analysis data and the commissioned well's sidewall coring analysis data, we took the sidewall coring's rock pyrolysis, saturated hydrocarbon gas chromatography, and fluorescent microgram analysis as technological means. Meanwhile, we emphasized on the evaluation of the thick reservoir and thin-poor layer to establish the method of interpretation and evaluation of water-flooded layer and logging in la-sa-xing oilfield. It doesn 't not only raise the application level of logging data, but also the delicate evaluation level of thick reservoir. Moreover, it has provided interpretation basis for the development, layer selection and perforation of thin-poor layer while secondary and tertiary infilling is going, which dramatically enhanced the development results of thick reservoir and thin-poor layer.

摘要：
As an important software defects analysis method, static analysis is wildly used in software coding and test. But this traditional method is inextensible and inefficient that users have to find defects artificially. A framework is implemented to locate defects called DDS(Defects description system) and an annotation Language was designed to describe defects which named DDL(Defects Description Language). The rules written in DDL will be saved in rule set and can be used by DDS to locate the defects automatically. The experimental results demonstrate that the method is available to identify defects in programs.

摘要：
This paper explored the approach to solve the problems, such as instability of loading force and difficulty in measurement of deformation. A portable and high precision stiffness surveying instrument was developed for measuring the stiffness of large sheet metal. Combined with the mechanism, high accurate force sensor and grating sensor were used to measure the loading-force and the displacement. A special software named Stiffness Test(ST) was developed to process data and calculate the value of stiffness. In the practical test, the results indicate that this instrument is feasible and effective.

摘要：
It was statement what the porous flow in grain bulks, its movement ways, influence factors and relationship with grain store are. The porous flow of the grain bulks is caused by the temperature and pressure different. It moves in three lines: convection between inside and outside the bulks, convection inside the bulks, and convection between inside and outside the storehouse. It is influenced by the temperature different, the grain bulks seal condition, the clearance between grain particles, the style of store house, and the grain storage ways, and so on. Used ways of the porous flow in the grain bulks well, the fumigant can be better-distributed, the grain temperature and moisture can be down, and the heat and humidity diffused can be avoided.
