相对边界

However, we know tantalizingly little about the comparative influence of geography on knowledge flow across organizational boundaries over different types of ties, despite warnings that research needs to account for the geographic context of ties to fully understand causal relationships.

然后，关于知识在不同结点跨地理组织边界流动的相对影响我们了解甚少，尽管研究需要解释结点的地理环境以充分理解原因之间的关系。

Based on Prandtl's momentum transportation, this paper calculates in detail the physical quantities such as eddy viscosities, and ratio of eddy viscosity to motion viscosity, total stresses with respect to relative position in three regions of viscous sub-layer, buffer layer, and main turbulent stream for non-Newtonian fluid flowing turbulently in ducts, which according to Karman's three layer models and measurement of fluid parameters in evaluation apparatus, discusses the influence of polymer drag reduction on flowing properties of non-Newton fluid, analyzes quantitatively principle of turbulent reduction phenomenon and condition of increasing reduction rate.

摘要以普兰德动量传递理论为基础，按照卡门的三层模型，通过室内模拟环道用0号柴油及加入减阻剂在圆管内的流动参数的测定，计算了非牛顿型流体管内湍流边界层的层流内层、过渡层、湍流中心的涡流粘度，涡流粘度与运动粘度比、总应力随相对位置的变化等定量参数，探讨了高分子减阻剂对非牛顿流体流动特性的影响，对湍流减阻现象的机理与增大减阻率的条件进行了定量分析。

In traditional Jiarong Zang nationality villages, inheritance and marriage rules which are represented by the "house name" make core family as the basic unit, and rule out the possibility of extended family and religious organization. Kinships among them become loose,but the rate of marriage alliance within the village is very high because incest taboo which is represented by the "house name" gives villagers more freedom to choose their marriage. And villagers also want to control the cost of marriage.A Jiarong Zang nationality village is actually a heavily heterozygote of blood-relation, marriage and place, a boundary of human relations.

在传统的嘉绒藏寨中，以"房名"为象征的继嗣和婚姻规则使核心家庭成为嘉绒社会最基本的单元，并且排除了扩大家庭和宗族组织的存在，亲属关系呈现为相对松散的状态，但以"房名"为记号的乱伦禁忌使绒人在婚姻选择上具有更大的自由，加之绒人降低婚姻成本的考虑，导致了高比率的寨内联姻，一个嘉绒藏寨实际上是血缘、姻缘和地缘的高度重合体，是人际关系的空间边界，日常交往体现出寨内的高度趋同性和整体性。

In VAX / VMS, a set of 0 to 32contiguous bits located arbitrarily with respect to byte boundaries.

在操作系统VAX/VMS中，一组0至32位连续位的集合，这些位相对于字节边界的位置可以是任意的。

Based on Geldart's particle classification and Ergun equation, and by taking into account the relative magnitude of viscous force and inertial force acted on the particles, a new transition equation between particle groups B and D is obtained.

根据Geldart 颗粒分类思想，以Ergun方程为基础，考虑粘性力与惯性力的相对大小，新建立了B/D 类颗粒的边界方程。

Results The left side of caudate lobes varied little in the shape and border,having a constant pedicle of vessels and bile ducts, which could be easily resected in surgery.Most of the blood vessle branches and bile duct of caudate lobe arose from the anterosuperior edge of Glisson's cap-sule.

结果 ①尾状叶左侧的形态、大小、边界变异不大，其血液及胆管引流有一个相对固定的&蒂&，手术切除比较容易；②尾状叶的血管供应、胆管引流繁杂，但均连接于Glisson's管的一、二级分支的前上缘；③肝短静脉数量、注入部位变异大，其走行多与腔静脉壁垂直。

In the myopic eyes the cartilaginous sclera was thicker relatively, and the ratio of binucleate cells/chondrocytes was higher than that in control eyes.

形觉剥夺使巩膜软骨层的相对厚度增加，双核软骨细胞百分数增加，实验眼软骨层和纤维层边界欠清，去遮盖后恢复正常。

The results show that: On the condition of this paper (1) The initial collision between two continents would cause the tectonic average stress near the collisional point to increase by 5-9 times as compared with regional stress field.

集中程度受碰撞方式、接触面积等因素影响。在本项目采用的模拟条件下，大陆碰撞初期产生的构造平均压力在碰撞点附近，相对于边界压力增大了5～9倍。

A conclusion is drawn that the air leakage intensity of goaf along the caving uncompacted zones around solid wall boundary is relatively large, namely, the air leakage intensity of two ends of working face is large, and the flow lines can be extended to the deep parts of goaf.
