The exploitation and utilization of coal resources are closely related to sustainable social economic development. To uncover the deformation seepage patterns on mining process, this study devised a new stress program with simultaneous changes in axial confining pressures, then performed experiments at various gas pressures. results show that residual exhibited stepwise change, relative same level decreased gradually, increase pressure led reduction deformation. In each grade, absolute...
The anisotropic thermal conductivity of ${\mathrm{Tl}}_{2}$${\mathrm{Ba}}_{2}$${\mathrm{CaCu}}_{2}$${\mathrm{O}}_{8}$ and ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ single crystals have been measured. In contrast to some earlier measurements on ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$, we found both an in-plane out-of-plane anomaly for these two compounds. We argue that phonon-phonon scattering may also play role in the phenomenon.
In this paper, the samples of different tumor tissue are imaged by phase contrast CT method based on synchrotron radiation in vitro. Then imaging results reconstructed three-dimensional limit, and 3D images for tissues compared. The experiments were performed at X-ray biomedical application beam-line (BL13W1) Shanghai Synchrotron Radiation Facility (SSRF). show that lung cancer has best quality experiments. By filter back projection (FBP), tomography obtained successfully. large alveoli...
A sound understanding of the water permeability evolution in fractured shale is essential to optimal hydraulic fracturing (reservoir stimulation) strategies. We have measured six samples from Qiongzhusi Formation southwest China at various pressure and stress conditions. Results showed that average uniaxial compressive strength (UCS) tensile were 106.3 10.131 MPa, respectively. The nanometre-sized (tiny) pore structure dominant characteristic shale. Following this, we proposed a...
Schema matching is a basic problem in many application fields as fundamental operation of schema. This paper analyses the advantages and limitations iMAP CM, proposes an extended schema system architecture between Database Schemas (ESM). First, ESM filters unreasonable matches by preprocess clustering process. Then it employs set special-purpose searchers to explore specialized portion search space discover 1:1 complex matches. estimates candidate selects optimal using similarity estimator...
Schema matching, the problem of finding semantic correspondences between elements two schemas, plays a key role in many applications. Currently, schema matching is largely performed manually by domain experts, thus time-consuming and labor-intensive process. In this paper, an improved algorithm proposed based on Similarity Flooding (SF for short) algorithm, which optimized algorithm. It adds pretreatment, so that calculation previous decreased greatly, efficiency precision enhanced,...
Wide area sensor databases are a hotspot research internationally at present. The query processing technology in wide is analyzed detail this paper. Focusing on the redundancy problem among multiple queries, queries algorithms proposed. First of all, it divides these into number sub-queries equally. Secondly, constructs attribute graph using all and deletes repeated eliminating algorithm. Finally, unites results based relations between gains users. Theoretical analyses experimental...
