该多孔陶粒具有制做方法简便、产品强度高、孔隙度大、吸水率适中、生产成本低等特点，多孔陶粒技术起到开源和化害为利的环保效果。

The reservoir traverse quite be stable, but the relative property is quite strong, by the southwest to northeast, the characteristic of the porosity growth is degression tendency. On longitudinal it is the permeability variation in a big way, and the aerosphere scope small.

研究区须家河组储层横向分布比较稳定，可对比性比较强，由西南向东北，孔隙度发育有递减的趋势；纵向上具有渗透率变化大、气层范围小的特点。

The anorthite component of plagioclase from Kela 2 reservoir was dissolved so completely by the pore fluid that the dissolution made great contribution to the pore volume, and the albite component suffered partially dissolution; by contrast K-feldspar did not dissolved in the ground water at all.

克拉2 气田中斜长石骨架颗粒中的钙长石组分基本上遭受了彻底的溶蚀，对次生孔隙的贡献较大，钠长石溶蚀程度有限，而钾长石基本上不被溶蚀。

The aperture in the door is so wide.

门上的孔隙太大了。

The metals distribution of Dagu canal and its tributaries in surface water, porewater and sediment have been studied.

本文研究和探讨了大沽排污河及其支流的沉积物上覆水、孔隙水以及沉积物中金属的沿程分布特征。

Finally the mechanisms and factors of decarburization of WC particles in spraying were explor...

结果表明：纳米结构WC-12Co涂层结构致密，孔隙率低，与基体结合状态良好；纳米粉末在喷涂过程中比微米粉末氧化失碳严重，并发生了不同的纳米晶粒的长大；纳米粉末在喷涂过程中的氧化脱碳程度不仅与喷涂工艺有关，还在很大程度上取决于粉末本身的结构特性。

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

随深度的增加，泥岩孔隙度和渗透率降低的幅度比砂岩大。

Because fluid pressure and rock stress change during sealed coring process, the degasification and rock pore volume change. As a result, there is difference between laboratory measuring saturation with in-situ saturation. Therefore the laboratory measuring fluid saturation has to be corrected to predict the in-situ fluid saturation.

在密闭取心过程中，由于流体压力和岩石应力的改变，导致流体脱气和岩石孔隙度改变，因此室内测定的岩心含水饱和度和实际油藏含水饱和度存在较大的误差，有必要将室内测定的含水饱和度校正到油藏条件下。

Moreover, the shear strength was increasing with the increase of the lateral confining pressure. In the unloading process, with the increase of deviator stress and the strain, the soil sample took on a dilatancy trend and showed a large negative pore pressure.

在卸荷过程中，随剪切应力的增大和剪切应变的发展，土样呈现剪胀趋势并在后期产生较大的负孔隙水压力。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.

结果表明，3种林型的叶面积指数变化总体趋势是一致的，均呈先上升再下降的单峰曲线，蒙古栎林和胡桃楸林都是在7月中旬或8月中旬达到最大峰值，花曲柳林是在8月中旬或9月中旬达到最大峰值；3种林型冠层孔隙度的变化总体趋势也是一致的，呈先下降再上升的单峰曲线，不同样地峰值出现的时间也不同，最低峰值在6、7、8、9月中旬均有出现；通过对不同月份的叶面积指数、林下散射光、林下直射光的变异系数分析表明，7—9月叶面积指数的空间格局是影响林下散射光空间分布的主要因素。

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.
