But when Fe/D113 precursor is pyrolysed in the range of 400-700℃, the crystal structure of the iron particle is different. The products are mainly iron oxides andα-Fe as Fe/D113 precursor pyrolysed at 500℃, and as the pyrolytic temperature increases to the range of 600-700℃,α-Fe and Fe_3C are observed. Meanwhile, Al_2O_3、MgO、MgAl_2O_4 were observed in Al/C, Mg/C, Al-Mg/C which were prepared from D113 resin at 1000-1300℃.

而在同样的条件下热解载铁树脂(Fe／D113)，热解产物中铁的晶体结构与热解温度有关，400℃热解产物为铁的氧化物；500℃热解产物为体心立方结构的单质铁；600-700℃的热解产物为bcc单质铁和铁的碳化物(Fe_3C)。1000-1300℃热解含Al、Mg及Al-Mg的D113树脂制得的Al／C、Mg／C、Al-Mg／C材料中Al、Mg主要以Al_2O_3、MgO、MgAl_2O_4形式存在。

Sustainable resin offers best of both worlds by Randy Hofbauer August 1, 2008 ARTICLE TOOLSEmailPrintReprintsShare With costs on the rise and packaging material waste being scrutinized, packagers are looking for lighter materials that perform just as well, if not better, than other resins on the market.

可持续树脂提供了两全其美由兰迪Hofbauer 2008年8月1号第TOOLSEmailPrintReprintsShare 随着成本的上升和包装材料的浪费正在审查，包装正在寻找更轻的材料，执行也同样，如果不是更好，比其他树脂的市场。

Exchnge properties of the resins with the reducers and oxidizers were also stu-died.

也研究了多种氧化剂和还原剂与自制树脂的交换性能，讨论了这些树脂容量与交换性能的关系。

Resin plate process is divided into film production processes and resin-version of the drying process itself.

METHDOS: Pulp cavity perforations were created in the pulpal floor of 55 extracted tooth. They were repaired with amalgam、flowable resin、Chinese gall compound recipe under amalgam、Chinese gall compound recipe under resin and MTA. Then the sealing ability of different materials by dye penetration were evaluated.
