151 The said method can also be used to calculate the adsorption factor to tracer by porous medium if the effective porosity of the medium is known.

152 The propagation velocity of seismic wave is dependent on the property of formations, such as formation component, elasticity, density, depth, geologic age, porosity and tectonic activity.

153 The results show that net burden pressure has obvious influence on porosity, permeability and rock compacting factor with little effect on pore configuration.

154 It is discussed that adiabatic material, as well as ratio of height and width effected solidification, shrinkage cavity and shrinkage porosity.

155 The results show that the microporosity morphologies transform from fine porosity to microporosity with the increase of the samples thickness of cast magnesium alloy.

156 For more highly cemented materials and limestones, significant difference in total porosity and effective porosity values may occur.

157 The minimal value of porosity is around 2.5 % though throat radius method and porosity - water saturation method.

158 The paper also studied the effects of porosity, fluid saturation in diphasic medium(water gas and oil gas) and change of overburden pressure on reflection wave AVO.

159 The main problem of decompaction correction is how to found a reliable porosity depth function or density depth function which expresses the compaction process of clastic rock.

160 According to Changchun-Siping Expressway testing data,[www.Sentencedict.com] the limits of faculative Porosity of the asphalt surface on expressway in frigid areas are presented.

161 And study the influence of welding speed and active gas for welding porosity defect.

162 The pore structure of EG was measured by nitrogen adsorption and mercury porosimeter methods. The space around EG particle was observed by SEM and the porosity of EG was measured by pycnometer method.

163 The pyrogenic decomposition property, porosity and graphitization extent of petroleum coke were investigated by analyzing the petroleum coke raw material.

164 By the linkage between the seepage coefficient, porosity and stress, the hybrid analysis model for coupled seepage and stress field in rock mass of equivalent continuum is established.

165 PICKETT method is mainly based on cross-plot of deep laterolog and porosity from well logs and core data.

166 According to cumulative porosity percentage of pores with various radius of coal, the pores with coal were classified into three categories, namely micro-pore, mesopore and macropore.

167 This is a Natural basalt stone with a homogeneous structure and some vacuolar porosity with a high feldspar content(around 75%).

168 A pulp sample keeping its original structure can be prepared by using freeze-drying technique and the porosity of the pulp can be determined.

169 The numerical simulation of 3D temperature field of castings during solidification process was carried out and the shrinkage cavity and porosity of sample castings were predicted using G/R method.

170 Moreover, M. alternifolia developed aerenchyma and adventitious roots during inundation, with root porosity in the flooded seedlings much higher than that of the control.

171 The influence of the ratio of Alg, W component and porosity upon the resistivity of Ag - W electro - contact material were examined by the computer simulation approach .

172 Based on the porosity data by core analysis, this paper presents two new equations and two new interpretation charts to calculate porosity in carbonate reservoir.

173 Simulation indicates that effective control of porosity in the jigger can be achieved via this system.

174 Results Pyrethroid residue in mandril increased by 400% and porosity reduced by 45% after heating electrothermal vaporizing liquid.

175 Shrinkage and shrinkage porosity, stress and deformation often occurs during the production of heavy steel casting.

176 The microstructure and porosity were observed under scanning electron microscope, and the pore diameter, rate of water absorption, and surface density were determined.

177 By adhesive test show that aggregate in the case of fully drying, porosity can enhance the adhesion.

178 If the effective porosity is given, the reflection coefficient of a solitary wave decreases also as the permeability coefficient increases.

179 The test results showed that the elastic modulus and yielding strength of porose material decreased with increase of its porosity, and the changing trend became slow gradually.

180 Among them, leaching of meteoric water has contributed less to the formation of anomalously high porosity zones compared to other factors.
