环形图

而且二体关联Green函数动力学把梯形图对应的短程关联与环形图对应的长程关联统一在同一个动力学方程组中，这是通常的Green函数理论所没有得到的新结果。

The two-body correlation Green 's function dynamics includes both ladder diagrams for short-range correlations and ring diagrams for long-range correlations in a unified way .

关于环形图的某些性质

On some properties of circular & graph

淬透性与等温回火温度无关。热台偏光显微镜中不同等温结晶温度下形成了不同的球晶形态：黑十字消光图以及环形消光图；

The hardenability is irrelevant to the isothermal tempering temperature . There are different morphologies with different isothermal crystallization temperature .

第二，中短期阶段强震震源区之外相当大范围中小地震或震群异常活跃，震源区反而平静，形成环形或R-t图空区。

Second , moderate and small earthquakes or swarms are quite active outside the source areas of strong earthquakes and quiescent within the source area during medium-and short-term stage , forming a ring or R-tgap .

并根据实际应用场合，给出了环形阵列的方向图分析方法与实例。

Based on practical use , the pattern analysis and an example of Uniform Circular Array are introduced .

针对环形或链式工程图提出了基于模式分解和符号匹配的特征识别方法。

A feature recognition method for annular or catenary graph was proposed , which is based on decomposition of model and matching of symbol .
