In this work, numerical simulations for the flow characteristics in a tank of KR mechanical stirring or/and gas injection are performed using the Fluent software. The Eulerian multi-fluid model is employed along with the standard k-ε turbulence model to simulate the gas-liquid flow in the stirring tank. A multiple reference frame approach is used to model the impeller rotation. Combined the KR mechanical stirring method and gas injection method, a new gas injection plus mechanical stirring method is proposed. The present results show that the gas phase distributes widely in the eccentric gas injection plus mechanical stirring tank. Therefore, the gas holdup would be increased and the better gas-liquid mixing effect can be obtained in the gas injection plus mechanical stirring case.

It is appropriate to establish underground pipeline network information system based on MapInfo software platform in many enterprises when taking account of the firm size and data amount. Since some functions of MapInfo in spatial analysis are not very strong relatively, it is difficult for MapInfo to fulfill some common functions about pipeline analysis such as spatial configuration, three-dimensional display, pipe exploding and so on. The thought and arithmetic to solve the above problems are approached based on respect theories of computer graphics and graph theory. A variety of function moduli have developed by means of senior computer languages and the system integration is realized.

Both GPS observations and errors have some speciality and complexity. After analyzing characteristics of study on reliability of GPS network, the target of inside and outside reliability of GPS network was deduced, a new reliability theory and outlier analysis method was established based on the correlative analysis theory. The targets of GPS network’s reliability were analyzed and the influence vectors Fi was taken as one of these. As a parameter, the correlative coefficient between Fi and the residual vector V can snoop and remove the outliers. This theory has a good application in correlative observation with multi-outliers analysis.

It is well known that reading ability is one of the most important abilities in English study,There’re many skills to improve reading ***,at the very beginning of the new school term,I noticed such a phenomenon——some teachers put a lot of time in the explanation of words and grammar,ignoring reading,the key in English *** this paper,I will talk about several typical reading skills as an ordinary English teacher,I hope that all the college English teachers can still put the stress on the training of the students’ reading ability.

1 Basic Situation of Mine Calamity Mitigation Funded by NSFC in the Past Six YearsFrom 1997 to 2002, NSFC Department of Engineering and Materials funded 118 projects on the study of mine by a total of 32.39 million RMB, among which, the number of projects relevant to mine calamity are 76, accounting for 64.4 percent of the total number; the sum of fund is 17.49 million RMB, accounting for 54 percent of the total sum (the detailed data are shown in Table 1); the number of general projects is 68, accounting for the main proportion of the total projects. In short, the number of projects and the sum of funds increase annually, as shown in Table 2, Fig. 1, and Fig.2.
