N-（3-Amino-4-methoxyphenyl）acetamide is an important intermediate for the production of azo disperse dyes,while it is still produced by reduction with iron powder in industry currently.

摘 要： N-（3-氨基-4-甲氧基苯基）乙酰胺是生产偶氮型分散染料的一类重要中间体。现有的工业生产方法仍全部采用铁粉还原。

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。

Except Ananas comosus, which is regarded as fruiter, other species have ornamental value. For example, the tank Bromeliads and silver-leaf tillandsia have already become new species in the international market.

除菠萝外，其它种类都具有较大的观赏价值，其中积水型凤梨和铁兰银叶种已成为国际市场上的新型花卉。

Notably, compounds 12–14 can be described as a 3D open–framework with nano–channels, compound 15 can be described as a 3D open–framework with double helical channels, while compound 16 can be described as a 3D heterochiral coordination polymer with double helical channels, which can be obtained by spontaneous resolution from the racemic phosphonic acid.X–ray powder diffraction analysis shows that compound 16 is a pure phase. Surface photovoltage spectroscopy of compound 16 indicates that it possesses positive SPV response in the range of 300–600 nm and shows p–type semiconductor characteristic.

值得注意的是，化合物12-14为具有一维纳米孔道结构的三维开放骨架结构，化合物15是具有双螺旋孔道的三维开放骨架结构，而化合物16是外消旋的有机膦酸配体通过自发拆分而形成的具有双螺旋孔道的多手性三维开放骨架结构。X-射线粉末衍射分析表明化合物16为纯相；化合物16的表面光电压光谱分析中，在300-600nm范围内有3个正的光(来源：ABC论文12网www.abclunwen.com)伏响应带，表明它具有p型半导体的特征；化合物16的诱导表面光电压谱进一步确定它的p型半导体的特征；磁性研究表明，化合物16中两Mn原子之间存在弱的反铁磁相互作用。

Basically, the distribution patterns of most trace metals can be divided into iron style and manganese style, both of which were controlled not only by their different remobilization degrees, but the different input from coal mining drainage, mainly influenced by pH.

Fe型元素与Mn型元素分布差异的原因可以简约的概括为：锰的界面循环极为强烈，导致再迁移程度很高；而铁的循环相对较弱，又容易受到上层硫酸盐还原作用的抑制，因此再迁移程度不高。
