The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

The characteristics of grain growth of metallic phase in direct reduction of high phosphorus oolitic hematite by carbon are discussed in the paper.

研究鄂西高磷鲕状赤铁矿直接还原过程中金属铁颗粒的长大特性，并着重讨论还原温度、渣相碱度及反应时间对铁颗粒长大的影响。

The results indicate that the pillaring process and crystal growing of anatase can be more easily realized by increasing the acid-base ratio of pillaring agents, raising the pillaring temperature and adding proper quantities of alkali. The calcination of Ti-pillared precursor brings the growth of TiO2 grain, at the same time the layer distance is declined. In order to obtain ideal products, the right pillaring conditions are: the acid-base ratio of pillaring agents of 13, pillaring temperature of 65 ℃ and the volume of alkali (2 mol/L) in pillaring liquid of 6 mL.

结果表明：在一定范围内增大柱撑剂酸碱比、提高柱撑温度以及加入适量碱，有利于插层复合反应的进行和锐钛晶型的生长；柱撑前驱物焙烧后TiO2晶粒长大，同时焙烧引起的脱水导致膨润土层间距的下降；为获得较理想的产物，合适的柱化条件为：柱撑剂酸碱比 n n (HNO3)为13、柱撑温度65 ℃和柱撑液加碱量为(2 mol/L NaOH) 6 mL。
