8.Objective To explore the effect and survival time by setting covered metallic expansible-self stents to treat postradiation esophago-tracheal fistula.
10.Some physico-chemistry properties of ultrafine zinc dust produced by the process of melting vapourizing shock-cooling of metallic zinc are measured.
11.Using nano-technology in surface, we are able to make metallic materials not only have surface nanocrystallization, but also macrocrystal basal body.
12.Objective:To explore the clinical effect and significance of silicone coated metallic esophageal stent to treat postoperative anastomotic fistula due to gastroesophagostomy.
14.Abstract: The Gibbs free energy and critical reduction temperature of vacuum silicothermic reduction producing metallic strontium were calculated and analyzed by thermodynamics.
15.The earliest muzzle-loading rifles were more difficult to load than smoothbore muskets, but the invention of metallic cartridges made possible the development of breech-loading mechanisms.
16.The authors discuss the applications of rosin and its derivant,including nonsulfide flotation and flotation separation of nonferrous metallic ions and organic compound from aqueous solution.
17.The color of the products is argent grey metallic shine, smooth, unknit. They mustn't be oxydic badly, lacking of sintering, over heating, delamination and cracking.
18.In this study, the performance of the supported metallic oxide catalysts for catalytic reduction of nitric oxide with carbon monooxide as a reducing agent were investigated.
19.Rare earth metals, such as metallic neodymium and metallic didymium (metallic praseodymium-neodymium), are used for rare earth magnets, mainly neodymium-iron-boron magnet.
20.There are volcanicity and kinds of metalliferous minerals formed by rush of current on the Mars,which is superior to the metallic element spread in the terram on the Moon.
