31 A semiquantitative prediction model of shrinkage porosity for titanium alloy castings has been established.

32 Commonly the dolomite crytals form a framework with evenly distributed porosity.

33 Young's modulus and the bending strength change almost in the opposite way of that of the porosity.

34 Experiments show that the accurate equation can express the relationship of porosity and bulk modulus of porous medium well.

35 The synthetic unconsolidated samples with weak cementation and high porosity were prepared using physical simulation technique.

36 The porosity and permeability of matrix, and the width, density and direction parameters of fractures were obtained by core analysis, well logging, seism and thin section observation methods.

37 Prediction of porosity is very important in reservoir analysis and oil gas prediction. In this paper G-LOG method is used to calculate velocity.

38 Results showed that compared with porous SiC ceramics, the MOR of SiC-cordierite was improved significantly, and the TEC decreased remarkably, and the apparent porosity also decreased.

39 For clean sandstone, the acoustic dispersion of compressional wave exists obviously when its porosity is more than 28%.

40 For direct quantitative measurement of porosity,[sentencedict .com] reliance must be placed on formation samples obtained by coring.

41 Porosity logging methods examining gas reservoirs of sandstone and argillaceous sandstone through acoustic wave and density are effectively used in coal beds.

42 Two kinds of failure theories are used to explain the failure types of sandstone with large porosity based on the experimental results under different saturated liquid conditions.

43 The porosity and fluid saturation of rock are key factors influencing AVO.

44 The karst fissure medium can be regarded as dual medium of porosity.

45 Compact rock formation formed a available reservoir with effective porosity and permeability because there are a many of fractures in it.

46 The origination and location of shrinkage porosity(hole)in the rudder horn was described by simulating the filling process of large pelagic cast-steel rudder horn using a CAE software.

47 Porosity increases along with the increasing of coagulation bath temperature, and doesn't have relation to pre-evaporation.

48 The results showed that good purification effects can be obtained, in which not only major coarse impurity particles was removed but also shrinkage porosity was effectively abated.

49 As one of the important indexes for the quality rating of plating, porosity can be used to evaluate the protection effectiveness of the substrate by the plating.

50 With the increase of sintering temperature, the apparent porosity of sample decreases, while bulk density, hardness and compressive strength increased.

51 The calculation method of primary wave and second wave speed were studied when the oil saturation and effective pressure of unconsolidated sandstone reservoir with high porosity in X Oilfield changed.

52 Along with the increase of deepness , to porosity and permeability, mudstone reduce much more than sandstone.

53 The information of petroliferous reservoir is contained in the differential signals between the resistivity and porosity curves of reservoirs.

54 With the advantage of low porosity and strong viscoplasticity, the salt caverns can be used to storage carbon dioxide absolutely.

55 The effect of FS content on membranes porosity has been discussed through measuring the porosity by hydrargyrum pression method.

56 In this paper we briefly analyze the mechanism of engendering pores in powder metal material(PM), and study the influence of welding speed and active gas for welding porosity defect.

57 The amplification ratio is related to non - dimension frequency and porosity.

58 Although automorphic or partial automorphic quartz cementation losses some intergranular pores in late diagenesis, the reservoir with relatively high porosity still can be formed.

59 All kinds of casting pig equipment surface should be smooth, do not allow to have porosity, sand, osteoporosis, etc.

60 Porosity and gas-saturation are two important parameters in quantitive reservoir interpretation.
