1金属注射成形(MIM)生产工艺与应用概要显示文摘粉末注射成形(PIM)包括金属注射成形(MIM)与陶瓷注射成形(CIM),是一种新兴的零部件制造工艺,其2010年的销售额超过15亿美元。介绍了MIM的市场概况,MIM工艺的发展历史、生产过程和适用材料;并重点介绍了典型MIM零件生产实例。R M German 2015粉末冶金工业2015,25,5:8
2The effects of Spirulina on anemia and immune function in senior citizens显示文摘Anemia and immunological dysfunction(i.e.immunosenescence)are commonly found in older subjects and nutritional approaches are sought to counteract these phenomena.Spirulina is a filamentous and multicellular bule-green alga capable of reducing inflammation and also manifesting antioxidant effects.We hypothesized that Spirulina may ameliorate anemia and immunosenescence in senior citizens with a history of anemia.We enrolled 40 volunteers of both sexes with an age of 50 years or older who had no history of major chronic diseases.Participants took a Spirulina supplementation for 12 weeks and were administered comprehensive dietary questionnaires to determine their nutritional regimen during the study.Complete cell count(CCC)and indoleamine 2,3-dioxygenase(IDO)enzyme activity,as a sign of immune function,were determined at baseline and weeks 6 and 12 of supplementation.Thirty study participants completed the entire study and the data obtained were analyzed.Over the 12-week study period,there was a steady increase in average values of mean corpuscular hemoglobin in subjects of both sexes.In addition,mean corpuscular volume and mean corpuscular hemoglobin concentration also increased in male participants.Older women appeared to benefit more rapidly from Spirulina supplements.Similarly,the majority of subjects manifested increased IDO activity and white blood cell count at 6 and 12 weeks of Spirulina supplementation.Spirulina may ameliorate anemia and immunosenescence in older subjects.We encourage large human studies to determine whether this safe supplement could prove beneficial in randomized clinical trials.Carlo Selmi Patrick SC Leung Laura Fischer Bruce German Chen-Yen Yang Thomas P Kenny Gerry R Cysewski M Eric Gershwin 2011Cellular & Molecular Immunology2011,8,3:2
3金属注射成形(MIM)设计与应用指南显示文摘一位设计师对MIM工艺了解越多,采用MIM工艺成功的机会就越大。本文为采用MIM工艺生产零件的最终用户提供了一些需要考虑的、有用的准则。虽然本文是为金属注射成形编写的,但提出的在设计中需要考虑的事项也适用于陶瓷注射成形(CIM)。R M German 韩凤麟 2014粉末冶金技术2014,32,4:2
