In the single crystal of C60 with a FCC structure,positron mainly appears outside the C60 molecule.The main annihilation space is the interspace between molecules.The calculated positron bulk lifetime in C60 is 352ps, which agrees with experiment value of 356ps in literature.In carbon nanotube bundles with different dimeters,as the diameter of carbon nanotubes increases,the main space where positron appears changes from the interspace of carbon tubes to the space inside carbon tubes,the radio between positron annihilation with valence eletrons and core eletrons becomes larger,the positron bulk lifetime in carbon nanotube increase rapidly first and come to be a constant at the end.The calculated positron lifetime of carbon nanotube with a dimeter of 0.8～1.6ns is 332～470ps,which agrees with the experiment value of 394ps.Positron annihilation has been studied in widly used compound semiconductors.

计算结果表明：在片层结构的石墨晶体中，正电子主要在石墨层间的空隙中湮没，计算出的石墨中的正电子寿命为208 pS，与文献中的实验结果215 ps符合很好；在金刚石单晶中，正电子主要在碳原子之间的空隙中存在并发生湮没，计算出的金刚石中的正电子寿命为115 ps，文献中的实验结果110 ps左右符合；在面心立方结构的C60晶体中，正电子主要在C60分子球壳内外侧及分子之间存在，C60球形分子中心正电子分布很少，正电子的湮没区域集中在C60分子之间的空隙区域，计算出的C60中的正电子寿命为352 ps与文献中的实验结果356ps相符合；对于不同管径碳米管束中的正电子分布，随着碳纳米管直径的增加，碳纳米管束中的正电子由主要在碳纳米管管间的区域出现转变为主要在碳纳米管管内中心的区域出现：碳纳米管束中的正电子与碳原子的价电子的湮没概率变得越来越大，与核心电子的湮没概率变得越来越小；碳纳米管束中正电子的湮没寿命先迅速增大，而后趋于一定值。

Ratios of SI vs interstitial fibrosis thus showed disproportionally milder interstitial lesions vs glomerular lesions in β6-/- vs WT.

SI与间质纤维化的比值显示β6-／-组小球／小管病变较WT组更加不对称。

Kidney pathology showed: the renal glomerulus in model group was damaged seriously, about 25% renal glomerulus was healthy. And the pathological changes involved renal glomerulus、tubulus renalis and interrenal nature. Those were broad response of inflammation.

8肾脏病理镜下见：实验组SD大鼠肾小球严重破坏，健全肾小球在25%左右，肾脏病理改变涉及肾小球、肾小管及肾间质，是广泛的炎性反应连续性破坏病变。

The charts of velocity vector of flow field outside the tube under five conditions with amplitude 1.3 mm and frequency 5—25 Hz were obtained,and the cosine of average synergy angle of flow field outside the tube was calculated.

实验及模拟结果表明：振动能够显著增加管外近壁区的流体速度，能够在振动方向上的管壁两侧形成有效的冲刷，随着振动频率的升高其管外近壁区的平均速度近似呈线性增加，在共振点出现峰值；相同区域内振动工况的平均场协同角余弦值要明显大于无振动工况，但不同振动频率间的场协同角余弦值变化较小。

This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。
