Using high speed schlieren photographs the microstructure of flame front surface in gas explosion was studied from the microscopic view.

In this paper the microstructure of flame in methane/air explosion has been studied indetail by using high speed schlieren photographs.

and from this leads out the deflection equation,and from shadow cloud methords we have messured the deflection curve of periphery fixed carbon/epoxy and normal anisotropic vertical and even distributed load,and we have compared it with its curve of theory.

Begins from equilibrium differenfial equation,and from shadow cloud methords we have messured the deflection curve of periphiry fixed carbon/epoxy and normal anisotrop-ic and EXCEPTED Concentrate force and we have compared it with its curve of theor

Cotton growth monitoring during chemical control stage using geostatistical image texture: a case study of Shihezi;

In order to describe the complex objects in three-dimensional urban geographic information system (UGIS) and for the need of three-dimensional spatial inquiry and the real representation with image textures, a spatial phenomenon was divided into six types of objects including point object, line object, face object, body object, DTM and raster image.

In the section of image texture acquisition,to propose distribution acquisition points according to object shape and distribution o.

They are:TM multi-spectral image,single temporal JERS-1 SAR image and the small scale texture image extracted from multi-temporal JERS-1 SAR images based on .

Using shadow-moire to determine 3D-profile can not only distinguish the outline of object directly,but also can get the real value of 3-dimension.
