Adipose-derived stem cells （ADSCs） assume essential roles intissue homeostasis and aging and have been explored as regenera-tive therapies for a broad range of diseases including physiologicaland pathological aging [1 ]. These multipotent cells are plastic, cap-able to differentiate and transdifferentiate to a range of cell types[2]. With aging, diseases and inundergo cellular senescence [3].vitro passing, ADSCs decline andFor therapies, typically cells fromyoung adults before 5-8 passages should be used, posing majorobstacles for conditions requiring much more cells [4].

When the high-income East Asian economies entered the upper-middle income stage,their long-term growth was sustained by their real manufacturing output share and total factor productivity(TFP).This is a typical pattern that is highly consistent with classical development economics,which sees manufacturing as the engine of economic *** China became a middle-income country,its share of real manufacturing output and TFP both fell over the same period,exhibiting a theoretical and empirical tendency toward“premature deindustrialization”that increases the risk of being caught in the middle-income *** China’s development as a manufacturing power,advancing high-tech manufacturing and improving the quality and efficiency of traditional industries are realistic options for the country’s industrial development strategy.

由平均粒径为0.2μm的TiC,TiN细粉,经1430℃,1h真空烧结制备了Ti(C,N)基金属陶瓷。由扫描电镜和强度、硬度测量研究了金属陶瓷的微观结构和性能。原料粉末以聚氧乙烯十二烷基醚为分散剂,蒸馏水为液体介质,溶液pH值保持在6～7之间,并使用超声波分散,悬浮液过筛后烘干。扫描电镜分析表明:经分散后的粉末颗粒团聚较少、分散良好。分散后细粉以相同工艺制备得Ti(C,N)基金属陶瓷。与未分散细粉烧结体对比表明:由分散细粉获得的金属陶瓷的硬度、抗弯强度均优于未分散细粉制备的烧结体,前者的硬度HRA为90.2,抗弯强度为2108MPa;后者分别为89和1983MPa,其微观结构特征为存在较多的细小均匀的黑芯白壳包覆层结构。细粉分散后,颗粒大小的分布较均匀而影响了液相烧结中的溶解析出过程,这是金属陶瓷微观结构和性能得到改善的重要原因。
