Based on the above experiments, the author studied the mixed metallic pillared and modified montmorillonites. The experimental result indicated that the microporous structure of Fe-Al-PLMs was affected by the changing of interlayer Fe-Al polymer with different Fe/Al ratio. But the presence of Al iron was helpful to incorporate Fe iron into interlayer of montmorillonites.. Introducing Zr helped Al-PLMs getting better larger spacing, thermal stability, surface area and pore volumes. Its successful to apply Zr-Al-PLMs to treat wastewater containing Cr iron. The experiment of modifying Al-PLMs by PVA showed that the order of adding starting materials (Al-pillaring solution, PVA, montmorillonite solution) was related to the property of Al-PLMs. The PVA as precursor was beneficial for Al to go into interlayer of the clay and to form larger basal spacing porous clay. The surface area and pore volumes of Al-PLMs increased mainly because of increasing the external surface area and mesoporous volumes after acid-activating. This conclusion confirmed that the microporous structure of pillaring clay depends upon the interlayer pillar.

实验结果表明:在Al-PLMs中引入Fe离子,不同Fe/Al比制得的Fe-Al-PLMs因层间的Fe-Al聚合离子结构不同而影响其微孔结构,但羟基Al离子的存在有利于Fe离子进入蒙脱石层间;在Al-PLMs中引入Zr离子,有助于其层间距、比表面积、孔体积增大,所得Zr-Al-PLMs应用于含Cr废水处理效果显著;PVA改性后的Al-PLMs其物化性质变化与铝柱化剂、PVA溶液、蒙脱石溶液三者不同添加顺序有关,说明PVA的前撑有利于Al进入蒙脱石层间得到较大层间距的Al-PLMs;经酸化处理得Al-acid-PLMs,其比表面积增大以外表面积为主,孔体积增大以中孔为主,这也证实了柱撑蒙脱石的微孔结构取决于其层间的柱化物。

There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.

人及哺乳动物体内有四种结构及药理学性质略有差异的异物体,分别为ET-1、ET-2、ET-3、ET-β,而在人主要是ET-1,在生理条件下,ET-1在血浆中含量较低,约为5ng〓,故ET-1不是一个循环激素,而是局部合成释放,局部起作用的活性物质,半衰期约1小时,ET-1是目前已知的最强的血管收缩剂,对静脉的作用比动脉强,在血管床,ET受体有A、B两型,A型主要分布在平滑肌细胞,B型主要分布在内皮细胞,它可以通过旁分泌途径刺激内膜增生,具有有丝分裂原效应,可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩,使静止期SMC进入增殖期,还可以通过信号传导途径,与bFGF、GTF-β、PDGF等生长因子协同作用,起共有丝分裂原作用。

The results show: the strongest bond is the Al-Al bond in the segregated cell without containing vacancy, where the Al atomic covalence radius is greater than that of Li atom in the cell; while the strongest bond is the Al-Li bond in the segregated cell containing vacancy, and the Al atomic covalence radius in the cell is less than that of Li atom. Since the difference of electronagativity between the Al and Li atoms is obvious, it is inclined to formed the Al-Li segregated cell of short range order structure in the condition of vacancy present. The short range order structure containing vacancy is probably the embryo or precursor structure of the metastable phase δ′(Al3Li). Because the strongest covalent bond in the Al-Li-vacancy segregated cell in alloy formed in quenching is the main strength reason for supersaturated solid solution of alloy. The bond net of succeeding precipitation of δ′(Al3Li) has the picture of anisotropic Al-Al bonding and the bond intensity enhanced. Since the δ′(Al3Li) is coherence with matrix, the bond net strength is enhanced by the precipitation of δ′(Al3Li) and so strengthen the alloy.

计算结果表明:不包含空位的偏聚晶胞的键络最强键为Al—Al键,其中Al原子的共价半径较Li原子的共价半径要大;而含空位的偏聚晶胞的最强键为Al—Li键, Al原子的共价半径要比Li原子的共价半径要小;在空位存在的情况下,由于Al原子与Li原子的电负性相差明显,促使Al和Li原子结合,倾向形成Al-Li短程序结构偏聚区,这种含空位的短程序结构很可能就是δ′(Al3Li)亚稳相的前兆结构和生长胚胎;由于Al-Li-空位有序偏聚晶胞的Al—Li键络比基体键络要强许多,因此,淬火过程中合金生成的Al-Li-空位偏聚晶胞对合金过饱和固溶体起主要强化作用;后续析出的δ′(Al3Li)亚稳相键络各项异性显著,键络强度明显提高;由于Al3Li与基体共格,其大量均匀弥散析出起到提升基体整体键络强度,同样对合金产生强化作用。
