With increasing undercooling, the solidification microstructures of the alloys have changed, for example, grain refinement, transformation from regular rod eutectic structure to spherical anomalous eutectic grain structure with particulate morphology; while at higher undercooling, fine regular eutectic structure was observed.

随着过冷度的增加，其凝固组织发生了一系列的变化：晶粒逐渐细化，凝固组织从规则棒状共晶向异常粒状共晶组织转化，最后得到显微结构细小的胞状共晶团组织。

On day 7, 15, 30 after injection, the renascent blood vessels were more in number, the KDR area density and the KDR mRNA expression in splenic tissues were higher in VEGF group than the control group, while on day 60 there were no significant differences in the area density of renascent blood vessel, the KDR area density and the KDR mRNA expression between the two groups.

外源性VEGF能够促进移植脾组织内血管生长，自体脾组织移植术后7~15 d开始静脉应用VEGF是促进血管再生的较理想时间；外源性VEGF可能是通过与移植脾组织内所表达的KDR结合发挥作用。

According to economic and minimum of transaction cost principle, we must try hard to seek equilibrium of supply among government, market and Non-profit organization and establish diversification of institution arrangement and polycentric system of provision of public goods and public-private rivalship and partnership so as to achieve social optimization of supply of public goods and to meet people's needs and realize public interests.

根据资源优化配置的经济合理性原则和交易成本最小化原则，努力寻求政府、市场和非营利组织在公共物品供给领域的均衡点，构建公共物品提供的政府、市场、非营利组织复合型制度安排与公共物品供给的多中心体制和互补机制；建立政府与市场、政府与非营利组织的竞争——合作伙伴关系，以达到公共物品供给的社会整体最优，满足人们需要、实现公共利益。

Results The anesthesia range was narrowed and anesthesia duration was shortened with the prolongation of epidural catheter placement,Epidural roentgenography showed that the medium diffused normally within epidural space,biopsy of epidural tissues showed that there were inflammative cells infiltration and fiber proliferation with longer epidural catheter placement（more than 4 weeks）,without significant differences between both groups.

结果 随着硬膜外腔置管时间延长，麻醉阻滞范围变窄，麻醉阻滞时间也明显缩短，两组之间没有明显区别；硬膜外腔造影显示：造影剂在硬膜外腔扩散良好，无明显受阻；组织学检查显示：置管时间长(4周以上)的动物，硬膜外组织炎细胞浸润、纤维组织增生、硬膜增厚，而且随置管时间延长，变化加显著，但两组之间没有明显区别。

Methods Mouse models of tibia fracture healing were established, and callus samples were collected 1, 3, 7, 14, 21 and 28 days after fracture. The development of callus and new bone formation were evaluated with roentgenology, Micro-CT and tetracycline double labeling method, and the expression of HIF-1α, vascular endothelial growth factor, Runx2 and ALP in callus were detected with RT-PCR, Western blotting and immunohistochemistry. The relationship between HIF-1α and fracture healing was analysed.

建立小鼠胫骨骨折模型，骨折后1、3、7、14、21、28 d取材，应用X线摄片、Micro-CT和四环素荧光双标记技术，观测骨痂组织的演变和新骨形成状况；采用RT-PCR、Western blotting和免疫组织化学方法，检测骨痂组织细胞HIF-1α、血管内皮生长因子和成骨性标志物（Runx2和ALP）的表达状况，分析HIF-1α与骨折愈合进程的关系。

Disk height index of intervertebral disks on X-ray films, areas and average T2 relaxation time of high intensity zone of disks on T2-weight MRI and histological score on pathological sections （HE staining, Masson staining and safranin O-fast green staining） were measured at 2 months, 4 months and 6 months after operation.

术后2、4、6个月时对正常及模型椎间盘观察X线片上的椎间盘高度指数、MRIT2加权相上的椎间盘高信号区的面积和平均T2弛豫时间、椎间盘纤维环损伤区的形态学变化、组织病理切片（HE染色、Masson三色胶原染色和番红O-固绿染色）椎间盘组织形态学变化、生物化学变化和组织学评分等指标。

Foreign journalists of a certain generation have a vivid memory of Honduras in the 1980s when the country was a military base, organised and funded by the United States, for the operations of the "contras", the paramilitary forces that invented a civil war against the Sandinista government in neighbouring Nicaragua.

某一代的外国记者对上世纪80年代的洪都拉斯记忆犹新，那时候的洪都拉斯是一个军事基地，由美国组织和提供资金，用于准军事组织"尼加拉瓜反抗军"的作战，该组织发起了针对邻国尼加拉瓜桑地诺总统的内战。

SOC phenomena does not appears in classical one dimensional sandpile model, but for two or three dimensional model, it does. However, some people did some experiments with rice and find the SOC existing in one dimensional rice pile, it is not fit with the classical sandpile model. Nobody explained this phenomena.

在经典的一维沙堆模型中，沙堆崩塌时并没有出现自组织临界现象，只有在二维以上的沙堆模型中才出现自组织临界现象，然而，后来有人用米粒做实验，发现一维米粒堆中存在自组织临界现象，这与经典的一维沙堆模型相违背，但是却没能对这种现象作出一个较好的解释。

The article summarized the relationship of meat quality and type of muscle fiber,diameter of muscle fiber,density of muscle fiber,the percent of muscle fiber,the percent of connective tissue,the percent of fat tissue in muscle, sarcomere length and so on.

肌肉的组织学特性与肉质具有一定的相关性，本文综述了禽类骨骼肌肌纤维类型、肌纤维直径、肌纤维密度、肌纤维面积比例、结缔组织面积比例、脂肪组织面积比例以及肌节长度等组织学特性与肉品品质的关系。
