In chapter 5,we introduce the De Morgan algebra of metric and investigate the pseudo-metric Uniformity and the pseudo-metric topology and the separation axioms in De Morganalgebra of metric.We establish the Baire category theorem and the Banach contraction theo-rem,the Edelstein contraction theorem and other fixed quasi-atom theorems in De Morganalgebra of metric.In final,we give a sufficient condition for the metrization of a De Morganalgebra of topology.

在第五章里，我们地德摩根代数中引进了伪度量，探讨了伪度量一致和伪度量拓扑以及德摩根度量代数的分离公理，得到了Baire范畴定理、Banach收缩定理、Edelstein收缩定理以及其它不动拟原子定理，最后给出一个德摩根拓扑代数可度量化的充分条件。

If, however, to figure out the financial crisis in the U.S. and around the clock to run down the track, in fact, relations with China, because in the U.S. financial tree of tree root system, there is no correlation with the Chinese a few, China against the United States investment in the financial sector, up to a "rattan wrapped around the tree" instead of "root root bound."

但是，如果搞清楚美国这次金融危机的脉落和前后的运行轨迹，其实和中国的关系并不大，因为在美国这棵金融大树的根系里，没有几根与中国相关，中国对美国金融领域的投资，至多是"藤缠树"而不是"根缠根"。

METHODS: The endodontic instrument was assumed as a metal conical bar. The normal stress of bending loads and the shear stress of torsional loads were calculated with the knowledge of mechanics. The relations between stress and such parameters as angle and radius of canal curvature, radius of instrument, polar moment of inertia, and metal elastic modulus were analyzed. The criteria for yielding and fracture of the instrument were discussed.

将根管器械刃部假设截面为圆的金属细锥杆，利用材料力学及断裂力学的原理与方法，分别计算根管器械在弯、扭载荷下的应力分布，分析应力与根管弯曲角度、根管弯曲半径、器械直径、器械横截面极惯性距、金属弹性模量等参数的确切关系；探讨器械屈服、断裂失效的准则。

At the root canal therapy process, hidden in the root canal isthmus, bifurcation area, triangle, shape and irregular dentinal tubules within the Enterococcus faecalis prepared by mechanical means it is difficult to remove, it can be biofilm, proton pump tolerance mechanisms such as root canals harsh ecological environment, to avoid conventional drugs, the role of disinfection, resulting in the failure of root canal therapy.

在根管治疗过程中，隐藏在根管峡部、分叉区、三角区、形态不规则区及牙本质小管内的粪肠球菌难以用机械预备的方法去除，它可通过生物膜、质子泵等机制耐受根管内苛刻的生态环境，躲避常规消毒药物的作用，从而导致根管治疗的失败。

The influencing tendency,principle of action and the extent of influence of eight factors effecting on the undercutting of external toothing involute columnar gear are discussed.

讨论了外啮合渐开线圆柱齿轮根切的全部共8个影响因素的影响倾向、作用原理和影响程度，给出了一个新参数——根切系数，用以衡量根切倾向的大小，使对渐开线齿轮根切的产生条件的认识更为全面。

The results showed as:(1)Gegen decreases fasting insulin and insulin resistance index and increases insulin sensitive index of rats of insulin resistance induced by dexamethasone significantly;(2)Gegen can improve glucose tolerance of rats of insulin resistance but not to alloxan indued diabetes mice;(3)Gegen increases glucose intake of 3T3-L1 adipocytes and improves the insulin resistance of 3T3-L1 adipocytes induced by dexamethasone significantly;(4)Gegen can activate peroxisome proliferator- activated receptor gamma, make it bind to PPAR response elements;(5)Gegen can up-regulate mRNA expression of PPAR v ,aP2 and adiponectin.

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

硝态氮含量以短缩茎中最高，叶和叶柄中次之，根中最低，且根/冠比越大的品种，其整体植株中的硝态氮含量越低；根尤其是侧根NR活性较高；叶肉和叶柄中硝态氮含量均与根中以内、外源硝酸盐为底物的NR活性呈一定的负相关。

Results In healthy subjects, L2-L5 nerves were displayed clearly by MRN, with a round or ellipse ganglion of 3-6 mm in diameter, and smooth stick-like nerve root and trunk, 2-5 mm in diameter. The signal intensity was higher in ganglion than nerve root or trunk. 40% of nerve root sheath was surrounded by small amount of cerebrospinal fluid, Femoral nerve was displayed in all subjects, while only 83.3% of obturator nerve and 43.3% of lumbosacral trunk were manifested. Lamellar blurred hyper-signal intensity was seen around 80.9% of lumbar plexus in GBS, but none in CIDP.

结果 正常组MRN可清晰显示腰2~5神经的走行，神经节呈圆或椭圆形膨大，大小约为3~6mm，神经根及干呈条状、边缘光滑，大小约为2~5mm、神经节信号高于神经根和干，40%的神经根鞘有少量脑脊液，股神经、闭孔神经、腰骶干的显示率分别为100%、83.3%、43.3%。80.9%的GBS腰丛神经周围有片状模糊高信号，神经根和节大小和信号无明显改变，25%神经干增粗，50%的神经干信号增高，边缘模糊。
