Methods Fortythree cases of Itraarticular Fracture of the Calcaneus(46 feet) were treated with limited internal fixation with small incision and artificial bone implantation from June 2003 to June 2007.There were 34 male(37 feet) and 9 female(9 feet). Small incision was used extracalcaneus,collapsed facies articularis posterior calcanei after reduction,air containing space of Calcaneus were fiiled with hydroxyapatite ceramic artificial bone.

选取生长良好的第5代兔骨髓基质干细胞与海藻酸钙纳米羟基磷灰石胶原复合材料体外复合培养。

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.

其稀土元素北美页岩标准化配分型式主要分为两类：一类为中稀土略显富集的帽状形态的稀土元素配分型式，微弱的铈负异常或无铈异常，以极乐矿段砂屑磷块岩样品最为典型；另一类为轻稀土、中稀土和重稀土自然分异的三段弧形折线衔接而成的稀土元素配分型式，铈负异常较明显或微弱的铈正异常，以叠层石柱体磷灰石最典型。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
