Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。

Sample analysis shows that within alumina glaze formula, when Si/Al〈4.0, there is anorthite phase and little quartz and submellite to separate out; When Si/Al〉4.0, sample stays fine at glass state; anorthite crystal forms at the highe

样品呈良好的玻璃态；高铝釉式（Si／Al〈4.0）汝瓷釉内钙长石晶体在最高烧成温度（1260℃）保温过程中就已生成，在降温过程中晶体继续长大。

Hence, to solve issue about bimetallic interface compatibility become key technology for successful preparation of Al-Pb composite.

因此如何解决Al、Pb双金属界面的相容性问题，是成功制备Al-Pb复合材料的技术关键。

In this study, two kinds of chemical composite single crystals , Ni〓Al and Ni〓Al+B, were grown by Bridgman method.

Ni〓Al中复杂的晶体缺陷，反常的屈服行为以及单向变形行为对晶体取向和温度的强烈依赖性，使得其在循环载荷的作用下将具有更为复杂的行为。

He is often identified as Dhul-Qarnayn in Middle Eastern traditions and is called al-Iskandar al-Kabeer in Arabic, Sikandar-e-azam in Urdu, Dul-Qarnayim in Hebrew, and Tre-Qarnayia in Aramaic (the two-horned one), apparently due to an image on coins minted during his rule that seemingly depicted him with the two ram's horns of the Egyptian god Ammon.

在中东传统中他被称为&Dhul-Qarnayn&，在阿拉伯语中被称为&al-Iskandar al-Kabeer&，在乌尔都语（现今巴基斯坦使用的语言之一）中被称为&Sikandar-e-azam&，在希伯来语中被称为&Dul-Qarnayim&，在阿拉姆语（耶稣基督时代的犹太人语言，旧约有的是用这种语言书写的，现今有部分叙利亚人还在使用）中被称为&Tre-Qarnayia&。

Al-Shattanawfi in Bahjat al-asrar mentions many of his miracles, each time giving a chain of transmission.

Al-Shattanawfi in Bahjat al-asrar 提到了他的许多奇迹，每个时代给予一连串的显示。

The effect of Al content on the Zener relaxation peak in annealed Fe-Al alloys has been investigated using a computer-controlled automatic inverted torsion pendulum through free-decay and forced vibration method.

在多功能内耗仪上用自由衰减和强迫振动方法研究了Al含量对退火态Fe Al合金Zener弛豫的作用。

The explicit solution of the strain energy release rate of crack propagation along the pure bend sandwich beam specimen has been deduced in the paper by use of the superposition principle of the energy and section inversion method. Based on the critical load of crack propagation along the interface through the testing measurement, the fracture toughness of four-point bending Si3N4/Al/Si3N4 specimens along Si3N4/Al diffusion joining interface has been obtained by using the explicit solution.
