Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

在明矾与氨水沉淀物经过滤后再额外添加不同硫酸铵的比例，1200℃ 1hr煅烧后，发现添加硫酸铵比例在1以上，其型态亦为蠕虫状纤维，当以1500℃ 5hr煅烧，蠕虫状纤维型态粒子亦变为又大又胖，其粒子尺寸长度约为 2 μm 宽度约为 500 nm；且将煅烧1200℃ 1hr测其比表面积值，会随著硫酸铵的添加量增加，粉体的表面积会增加且粉体变细，添加硫酸铵比例为 4 者所得粉体粒径最小，从比表面积所得结果估计约 150 nm 。

The results: the phase transferring range of TiO2 is between 600-750℃; with the doping of tourmaline, the UV-VIS adsorption spectrum of Nd/TiO2 was basically not affected, and showed a gradual Einstein shift with the increase of calcined temperature between 300-750℃; OH intensity of Nd/TiO2 could be enhanced both in irradiation and in no irradiation when tourmaline was added in it; the doping of 0.6% tourmaline led to the best photocatalytic activity of Nd/TiO2 and the best photocatalytic effect appeared when calcined at 600℃.

结果发现TiO2的相变转化区间在600~750℃范围内；电气石掺入对Nd/TiO2材料的光吸收范围基本没有影响，在300~750℃范围煅烧后，随温度升高UV-VIS图谱有逐渐红移现象；电气石的加入使得Nd/TiO2材料在光照及未光照条件下都起到增强OH强度的作用；在Nd/TiO2材料中掺入0.6%的电气石获得最好的光催化活性，600℃下煅烧光催化效果较优。

This paper also studied pyrogenation of composites which are made up of three polymer(polyvinylchloride,ethylene-vinyl acetate copolymer and nylon12) and the shell at different temperature through analysed pyrolysis mechanism.The study shows:the calcined shell has different effect on resin at different temperature, nylon 12 having amido and shell calcined for two hours at 600℃ can form the material which has resemblance in the structure of shell,so the pyrolysis speed of this composite is slower than pure nylonl2,but the effect is unideal.

通过分析聚合物的热降解机理，研究了三种聚合物(聚氯乙稀、乙烯—醋酸乙烯共聚物和尼龙12)与不同温度下贝壳组成的复合材料的热降解行为，结果发现：不同温度下煅烧的贝壳对树脂的影响不同，其中具有氨基的尼龙12与600℃煅烧2小时的贝壳可以形成类似贝壳结构的材料，所以这种复合材料比纯尼龙12的热降解速度慢，但效果不理想。
