Three-dimensional great deep distributed resistivity imaging instrument has been developed for gob detection. Poledipole array is selected for deep detection. Diagonal measurement method is adopted to reduce the number of data. To test the performance of the instrument, a Gob at Taochong in Anhui province was investigated using three-dimensional great deep distributed resistivity imaging instrument...
We observe the expression of HIF-1 after middle cerebral artery occlusion (MCAO) by immunohistochemical method.Thirty-six Sprague-Dawley healthy male rats, with body mass of 250-330 g, were used in this study. Thirty-six rats were randomized into 3 groups: pre-ischemia group, sham-operation group and control group, with 12 rats in each.Rats in the pre-ischemia group were created into pre-ischemia...
Through parallel and diversified optimizing activities in ant colony, Microhabitat Ant Colony Optimization Stratagem (MACOS) was advanced to improve the basic ACO from diversity of pheromones distribution, ant pheromone update strategy and diversity of information exchange. Basic Scheduling Rules of Ants (BSRA)was built up based on the characteristics of JSSP. Ant Colony Optimization Scheduling Rules...
Both size and distribution of oil mist droplet diameter are important factors for weighing atomized quality of oil mist in lubrication. However, because of the peculiarity of oil mist droplet, it is difficult to obtain its exact dimension. This article selects laser particle sizer which is based on the scattering theory of light to measure size and its distribution of oil mist droplet diameter. At...
To make external network power station drawing circuit diagrams more expediently, an automatic graphic generation based on CIM standard is developed. First, with the screen centre as basic point, the screen is divided into 4 areas, and various equipment lay aside separately according to certain rule. Next, voltage level structure table, bus bar structure table, transformer structure table and switch...
