During somitogenesis, zebrafish FoxD3 is known of maintaining the somitic expression of myf5, and subsequently regulates myogenesis. FoxD5, another gene of the FoxD family, is also expressed in forming somites of the anterior PSM. However, the regulatory function of FoxD5 in somitogenesis is not clear.

虽然已知斑马鱼中FoxD3在体节发育时，能维持myf5在体节的表现并藉此参与於肌肉的发育；但FoxD转录因子家族中的另一员，FoxD5，在体节发育时也会表现在presomitic mesoderm前端生成中的体节处，而这个FoxD转录因子是否在体节发育的过程中扮演调控的角色目前仍不清楚。

Through the microstructure analysis, it is found that there are ferrite, spiculate bainite in base material, weld metal area and heat-affected zone, and there is much dispersed Fe3C on ferrite and bainite, which indicates that weld joints of steel B610CF have better strength and toughness.

金相分析表明，焊接接头的母材区、焊缝区和热影响区组织均为铁素体和下贝氏体，在铁素体和贝氏体上还弥散分布着渗碳体，说明焊接接头的强度和韧性都较好。

In this paper the authors report on the biological characteristics of Al-sophila spinulosa Hook.

孢子—原叶体—孢子体的生活周期长，并且在丝状体、原叶体和幼孢子体阶段，无特殊结构去抵抗和忍耐一切不利环境因子的影响。3。

Results: ADC in MS group was increased in all regions of NAWM compared to controls(P＜0.05),significantly higher in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.01). FA value in MS group was decreased in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.05), the genu and splenium of CC,middle cerebellar peduncle showed an insignificant trend of lower FA.

结果：MS组的正常表现脑白质的ADC值均高于对照组(P＜0.05)，以胼胝体体部、内囊、侧脑室旁及额、顶、枕叶脑白质更为显著(P＜0.01)；MS组的FA值与对照组比较，胼胝体体部、顶、额、枕叶白质及内囊、侧脑室旁发现明显降低(P＜0.05)，以后4个部位更为显著(P＜0.01)，而胼胝体膝部、压部和小脑结合臂有降低趋势，但无统计学意义。

The network seepage flow analysis method of rock masses is a numerical method compatible with Block Element Method on the basis of the assumption that the rock blocks are unpermeable while the discontinuities are permeable.

岩体网络渗流分析方法是在假定岩石块体不透水、岩体中渗流仅通过结构面进行的基础上建立起来的一种与块体单元法配套的岩体渗流数值模拟方法。

The results show:there are a lot of dislocation martensites,a little of twincrystal martensites,remnant austenites and Cr 23 C 6 compounds.The unsufficient diffusion is the reason of the chemical composition distribution of the fusion zone.The amount of martensites and the formation of microstructure are mainly decided by the chemical composition of the base me...

结果表明，马氏体带含大量位错形马氏体、少量的孪晶形马氏体、残余奥氏体以及Cr23C6 化合物；熔合区化学成分分布特征缘于不充分的扩散传质；马氏体的数量、亚结构特征以及Cr23 C6 化合物的形成取决于母材和填充金属的化学成分。

The influence of untransformed austenite areas on the properties of austenitic-bainitic ductile iron is discussed.

该文用彩色金相技术显示了奥氏体—贝氏体球墨铸铁中未转变奥氏体区的组织，用定量金相研究了等温淬火温度和时间对未转变奥氏体区的影响，讨论了未转变奥氏体区对奥—贝球铁性能的影响。

However, fully consideration of special structure and physiological function of CRP is critical to investigate whether CRP provide protect effect or pathogenic effect in the progression of atherosclerosis. CRP is a member of pentrxins family, which consists of five identical, noncovalently associated 23-kDa protomers arranged symmetrically around a central pore with a 102 A external diameter. Each protomer has a recognition face with a phosphocholine binding site consisting of two coordinated calcium ions adjacent to a hydrophobic pocket. The opposite face of the pentamer is the effector face, where complement Clq binds and Fc receptors are presumed to bind. A cleft extends from the center of the protomer to the central pore of the pentamer. Both faces ofpentamer form a special bi-phase structure: one face is the ligand recognition phase, which can recognize apoptosis cells and enzyme modified low density lipoprotein in which PCh is exposed.

CRP是一种五聚体蛋白，外径为102 A，由5个相同的单体以非共价键结合，形成双面的环形结构，每个单体的配体识别位点或受体结合位点分别位于五聚体两个平面上，分别组成配体识别相和效应器相，从而构成特殊的二相性结构：一面为配体识别相，含有磷酸胆碱(phosphorycholine，PCh)结合位点，能够使CRP识别在病理条件下暴露出PCh的凋亡细胞、酶修饰低密度脂蛋白(enzyme modified low density lipoprotein，E-LDL)等。E-LDL是天然低密度脂蛋白(native Low density lipoprotein，N-LDL)在多种蛋白酶，如胰蛋白酶、神经氨酸酶、胆固醇酯酶等作用下的代谢产物，其主要特点是结构发生改变(N-LDL大小均匀，平均直径250±30 A，E-LDL大小差异极大，直径为100-2000 A)，暴露磷酸胆碱位点，能够被CRP识别；另一面为效应器相，能够与巨噬细胞、单核细胞表面受体FcγRⅡa结合，介导巨噬细胞、单核细胞识别及吞噬凋亡、坏死细胞作用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
