无明显结构的

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.

本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。

The level of free cash flows and the shareholding ratio of major external shareholders have no significant effects on the start-ups' leverage. However, in order to avoid the firm going bankrupt, the entrepreneur has the stronger motivation to reduce the leverage when he holds more shares, and the levels of the long-term debts and the bank loans decrease significantly with the increase of the entrepreneur's shareholdings.

进一步，受创业者与股东间代理冲突不及成熟企业严重的微观经济特征的影响，自由现金流和外部大股东持股比例对创业企业资本结构无显著影响，而高持股比例使得创业者倾向于选择低的债务水平，且创业者持股对长期负债和银行货款的负向影响较其对短期负债和商业信用的负向影响更为明显。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

For the longitudinal probability distributions of cross sections of unbonded prestress tendons, it is evident that the reliability index of unbounded prestressed concrete members decreases with the number of independent and identically distributed random variables decreases.

分析结果表明，体外无粘结预应力钢筋截面面积沿长度方向的变化，引起结构可靠指标的降低是比较明显的，可靠指标随着独立同分布随机变量的数目的增大而减小。

Results］the gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.the fibrin had degraded at 3 weeks. cell tracing showed that the labeled bone marrow derived mesenchymal stem cells remained viable and presented in the intratendinous region for at least 6 weeks, becoming more diffuse at later timepoints.at 3 weeks, collagen fibers appeared more organized and there were better morphometric nuclear parameters in the treatment group. at 6 and 12 weeks, there were no differences between the groups with regard to morphometric nuclear parameters.

结果］实验组相比对照组肌腱大体观察粘连差，肌腱活动性好。3周后纤维蛋白载体即降解，细胞示踪结果显示标记的骨髓间充质干细胞至少6周内仍可保持活性并存在于肌腱组织中，但之后逐渐扩散。3周时，实验组与对照组相比胶原纤维排列更为有序，且胞核形态结构更规则，但在6周及12周时，实验组与对照组胞核参数测定无统计学意义。3周时实验组比对照组具有更强的的生物力学特性，但之后则差别不明显。

However, the Mn content did not exhibit the same tendency as Fe did but showed the lowest value in the middle part of the silk gland.

Fe能够诱导丝蛋白的构象由无规线团和/或螺旋结构向β-折叠转变，但是Mn对丝蛋白的构象没有明显的影响。

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙，微乳头缺乏纤维血管轴心，每个微乳头细胞团和周边的纤维组织均存在无细胞的间隙样结构；瘤细胞CerbB-2、CgA和EMA。

We studied their properties by IR, NMR, OPM and DSC and found that the ratio of Cu2+/DK-C11-C12 affects the mesomorphic temperature range and the results show that chelating units can play a mesogen function.c Synthesis and mesomorphic properties study of Cu-coordinating liquid crystalline polysilsesquioxanes with heptyl group on the side chain.

2对以β-二酮为侧链的梯形无规聚硅氧烷铜络合物用IR，NMR进行了结构表征，用DSC，偏光显微镜等方法进行了液晶性能的表征，并与同类化合物的性能进行了比较和研究，结果表明：Cu~(2+)含量对液晶相温度区间有明显的影响。

It is shown that the ADFVLN, which has lower losses, high off-design performance and reliability, is superior to the vaned nozzle as the first stage and it also has more advantages than the early AFVLN, such as lower losses and less skewed boundary layer near the inner ring ect..

研究表明，这一新型轴流无叶喷嘴不仅具有原来同类喷嘴的优良性能，而且双出口结构和内环旋转的特点，使其流动效率明显提高，并省去两块隔板，缩短了机组的轴向尺寸，具有较高的工业应用价值。

After more than five years to practice, we Special Bridge, fortes tunnels, urban subway Anwa and conflicting, design and construction of integrated technologies, and rail switch, structural steelwork, OK-mechanical manufacturing technology to maintain a leading domestic level, online, bridges, tunnel, electrification, and other professional key technologies to reach or approach the advanced world level, in high-rise buildings, high-grade highways, high-grade renovation, and new breakthroughs have been made in the field of high-speed railway technology, a person I have no, I have good people, people who I turn, and constantly develop innovative mechanisms, and markedly increase the core competitiveness of enterprises.

经过五年多来的实践，我们在特大桥、特长隧道、城市地铁暗挖和盾构等设计与施工综合技术，以及道岔、钢结构、轨行机械制造等方面的技术保持了国内领先水平，在线、桥、隧、电气化等专业关键技术上达到或接近了世界先进水平，在高层建筑、高等级公路、高档装修、高速铁路等技术领域取得新突破，形成了人无我有、人有我优、人优我转、不断创新的发展机制，明显提高了企业的核心竞争力。

I didn't watch TV last night, because it .
