Experiments and data analysis In order to investigate the influence of pore pressure in the micropores of the matrix and also in the fracture, we prepare a cylinder coal sample from Datong coal mine which length is 100mm and because we want to compare the results of different conditions when different kinds of gases were sent into the sample, we cut the sample into two parts and each length is 50mm.

The physiotherapy advice included posturecorrection, ergonomic advice and physical exercises such as stretching exercises, strengthening exercises, aerobic exercises and stress reduction exercises.

Rough match is to extract the interlaced row and column data which means 1/4 of the template data, and then, interlaced row and column matching in the search image was processed, i.e. matching in the 1/4 range of the original image.
The matching speed of this method improved significantly due to the reduction of the extracting data.

The calculated data and test data for total grinding force are shown in Table1.

When the ap is15μm and vs=21m/s, the impact load appears a reduction tendency with increase of the workpiece velocity.

Introduction Ring ultra-lapping is the key link which determines the accuracy of rotating part and even the whole bearing, especially the ultra-lapping of the roller surface is the main factor affecting the service life and the reduction of noise and vibration.
It realizes data exchange by sharing memory and communication processor and the external server on a local area network (not shown in the figure), and can greatly improve communication ability of the embedded computer and the server by sharing memory and communication processor.
Corresponding to the structure of hardware above, including signal detection and processing module, ultra-lapping parameters of power supply real-time selection module, six kinds of control modules, data access and network communication module, these procedures are multitasking threaded programming complex, compiled by the c language.
It is relatively rare to share data access and network communication module for the existing CNC ultra lapping machine, but the development of embedded network products has been gradually mature, which can provide a lot of successful experience in the aspect.

Materials and Methods Selection of research area and data sources This research chose Fengxian and Jinshan Districts on Shanghai Hangzhou Bay North Shore as the research object, and selected related indexes like society, national economy, population, tourism, natural environment and environmental protection investment through analysis of tourism statistics, field survey data and social economy data in Fengxian and Jinshan Districts of Shanghai Hangzhou Bay North Shore, thus establishing a coastal area tourism ecological security evaluation model.
Since 2000, the index R has been increasing in Fengxian, which indicated that energy conservation and emission reduction were stressed as much as economic construction in coastal area in Shanghai.

Data Reduction The regional heat transfer coefficientis calculated from the regional heat transfer rate unit surface area from the inner wall to the cooling air, the local wall temperature() on each aluminum plate, and the local bulk mean air temperature (as: (8) The heat loss ( is determined experimentally by supplying electrical power to the test section until a steady condition is achieved for a no flow condition.

All identified peaks correspond to the phases of barium hexaferrite ferrite based on data base of COD (Crystallography Open Database) with the entry data number 96-100-8322 which has hexagonal crystal structure with space group Pb63/mmc (194) and lattice constants a = 5.9290Å. c = 23.4130Å.
From the refinement data, that derived samples are of better quality and refinements of samples are effective.
The result interpreted to be due to the reduction in crystal anisotropy field by changing of easy axis of magnetization from c-axis to basal plane [6, 7].

The noise of the M219 cavity is studied by using the hybrid SST-SAS method and validates the reliability of the method by comparing with experimental data.
The experimental data are from the QinetiQ wind tunnel.
