目的：用病例对照研究探讨肝炎肝硬化患者发生多重耐药菌感染的危险因素。

Study on Nitrided Case Structure with Relation to Unlubricated Rolling-wear Resistance

氮化层组织与干式滚动磨损性能的研究

The present case needs to reduce the air-resistance to the minimum.

现在需要的是把空气阻力减小到最低限度.

However, due to the precipitation of chromium nitrides in the nitrided case, conventional plasma nitriding usually deteriorate in corrosion resistance, which is unacceptable in many application situations involving severe corrosive attack by the environment.

然而由于氮化铬在氮化层中沉淀析出，在许多受环境严重腐蚀的应用场合，使传统的离子氮化耐腐蚀性能恶化，这是无法接受的。

By thermal gravimetric analysis of the TGA curves, horizontal centrifugal fiber forming process, and maintain the structure of the polymer molecules to the same case, the level of Spun fiber processing technology to improve the heat resistance of phenolic resins.

通过热重分析TGA曲线研究酚醛纤维耐热性。水平离心成纤过程，在保持聚合物分子结构不变的情况下，水平离心成纤加工工艺提高了酚醛树脂的耐热性。
