The calculated results based on the pressure-dependent spall porosities given by Tonk et al and Cochran et al are consistent but different from the calculated results based on Thomason's stress-dependent spall porosity.

Cochran等给出的依赖于压力的层裂空隙度方程所作的一维层裂试验数值模拟结果基本一致，而与基于P.F。 Thomason给出的依赖于应力的层裂空隙度方程所作的相应数值模拟结果有明显差异。

In molten ZnCl2 at high temperature, microporous organic framework based on phthalocyanine skeleton has been obtained from tetracyanopyrazine,and the dynamic trimerization reaction of 1,3,5-tricyano-benzene can lead to triazine-based material with high porosities.

在高温熔融的氯化锌存在下，四氰基吡嗪可以构建形成具有酞菁骨架的微孔材料， 1，3，5-三氰基苯可以发生三聚反应形成具有三嗪结构的微孔材料，均具有较好的多孔性能。

The morphology of the mineral dependents on the solution characteristics. The main component of mineral was hydroxyapatite containing a little of CO32- group which the Ca/P ratio is 1.53, similar to the major mineral component of bone tissue. The porosities of the mineralized and unmineralized 3-D porous PLGA were (84.86±8.52)% and(79.70±7.70)% respectively. The biomechanical strength was 0.784±0.156 N/mm2 in unmineralized PLGA and 0.858±0.145N/mm2 in mineralized PLGA.

结果：PLGA经碱性溶液水解处理后表面亲水性明显增强，在0.5倍SBF中仅有少量矿物沉积，在SBF及1.5倍SBF中矿化后表面可以形成明显的矿化物；矿化物的形态与矿化液的浓度有关；矿化物主要成分为羟基磷灰石，含有碳酸根成分，钙磷比为1.53，类似于人骨无机质。

As a result, we have obtained a large number of materials with different porosities,structure and surface chemistry, what is rarely found in the literature.

因此，我们已经获得了大量的材料具有不同孔隙度，结构和表面化学，什么是很少在文献中发现。

By knowing or estimating the matrix and fluid densities, the porosities of each formation can be calculated.

由已知的或者估计的流体密度和骨架密度可以计算出每个地层的孔隙度。
