大孔隙

With gradually larger scale, the precision that lacunarity indices reflect the landscape coverage. rate is poorer.

随着尺度逐渐变大，孔隙度指数反映景观覆盖度的精确程度随之降低。

The research indicates that the ground stress and pore pressure and the rocky Biot's elasticity coefficient play the leading role, and the other rocky mechanical parameters follow.

通过实例分析表明，在川西深层条件下，地应力、地层孔隙压力和岩石的弹性系数等参数的准确程度对井壁稳定性分析结果影响程度最大，而其他岩石力学参数的影响次之。

With emphasis on formation of micropore and variation pattern, pore-size distribution, specific surface area and characteristics of pores were observed and analyzed.

实验表明，炭化温度对炭化物的比表面积与比孔容积特性影响很大，较高温度的炭化物具有较发达的孔隙结构与较高的比表面积。

Deep in the earth, however, pressures are so great that open spaces of any kind are obliterated .

但是在地下深部，由于压力太大，使得任何类型的孔隙都归于消失。

It may be due to that the mechanical properties are over-shadowed by the influence of porosity.

这可能是由於孔隙之作用太大的原因。

The higher the total porosity, the greater the potential to provide water and air.

较高的总孔隙度，更大的潜力，提供水和空气。

Therefore, the effects of operation conditions become more significant as the increasing of porosity.

因此，孔隙率越大，上述参数的变化对传质的增强效果越明显。

It was shown that not only pore surface chemistry but also the pore structure of samples activated by air were different from those by traditional steam, carbon dioxide and potassium hydroxide activation.

研究结果表明，所制备的样品不仅具有特殊的表面结构，同时其孔隙结构也与其它方法所制备的ACF有较大差异；样品对低浓度下的极性分子如水蒸气有较好的吸附选择性。

The parameters are :① reservoir effective thickness;② reservoir porosity;③ reservoir volume efficiency;④ fair pay ′ s reservoir volume efficiency;⑤ distance to the fault;⑥ reciprocal of the square root of the distance to the fault ）;⑦ apparent fold strength coefficient;⑧ maximum principal curvature of structural plane;⑨ transversal section line curvature;and ⑩ longitudinal section line curvature.

摘 要 介绍了气井产能的确定方法及地质参数的选择与计算方法：采用初始二项式无阻流量、稳定产量及初始采气指数作为气井产能评价的指标；10项参数分别是①储层有效厚度；②储层孔隙度；③储容系数；④好储层的储容系数；⑤与断层的距离；⑥与断层距离开方的倒数；⑦视褶皱强度系数；⑧构造面最大主曲率；⑨横向剖面线曲率；⑩纵向剖面线曲率。

Besides, porosity is the most important function of the effective capillary radius of curvature and permeability values.

此外，孔隙度对有效毛细半径与渗透度有相当大的影响。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
