边缘密度

The edge internal branch crack of half-plane can be considered as a superposition of many single cracks, thus a set of Cauchy singular integral equations can be formulated, where the distributing dislocation density serves as the unknown function.

将半平面边缘内分又裂纹问题看作是许多单裂纹问题的叠加，建立了以分布位错密度为未知函数的Cauchy型奇异积分方程组。

This study aims to explore the following questions: differences of the genetic polymorphism among seasonal populations; differences of genetic diversity among four age groups and between two different gender populations; testifying the Ford and Chitty hypothesis; the relationship between the genetic diversity and geographic distance; the relationship between the genetic diversity and population density; edge effect on genetic diversity.

主要探讨以下问题：季节种群间遗传多态的差异；种群年龄组和性别间遗传多样性的差异；Ford和Chitty的假说；种群遗传多样性与空间距离的关系；种群遗传多样性与密度的关系；中心区、边缘区和半岛区种群遗传多样性的差异。

Soft-tissue masses: abut against bone leision, homogeneous or unhomogeneous density and signal intensity, well-demarcated boundary on T2-weighted images.

软组织内难以定性的钙质样高密度影：位于骨外软组织内、软组织肿块内部或边缘，CT上呈斑点状、不规则条块状钙质样高密度影，边界清楚或，不清楚。结果57例骨髓炎病人中，54例行CT检查，14例行MR检查。

Based on the developed iron loss of surface-mounted permanent magnet machine of Slemon and Xian Liu, the expressions of the peak and the time rate change of flux density in the teeth and the yoke are derived, considering the beveling edges of the PM. According to the basic concept of the eddy current loss, the analytic calculations of the average eddy current loss density in the teeth and the yoke are presented respectively. Hence, a calculation method for the iron losses of PM with beveling edges is presented.

One case was the chronic inflammation of the lacrimal sac showing a cystoid lump in the area of the lacrimal sac. One case was the chronic inflammation around the lacrimal sac showing a small lump with a low denstiy in its center in the area of the lacrimal sac. One case was orbital cellulitis showing the density of the right part in the orbit outside the eyeball becoming higher, and having not a edge.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
