Study of Physical Properties of Ring Polymer Confined in Obstacles

环状高分子在障碍物晶格空间中的行为被认为与支化高分子（晶格动物）的行为相似。我们研究了环状聚合物在一个空间中的正方形格子的正方形障碍物在两个维度。证实了具有排斥体积的受限环聚合物的行为可以用基于blob图像的标度关系来理解，并研究了在恒定键数下具有随机移除和添加的支化聚合物与粗粒模型的对应关系.

Behavior of a ring polymer confined in a space with lattice of obstacles is considered to be similarto that of a branched polymer (Lattice Animal). We examined the ring polymer in a space with square lattice of square obstacles in two dimensions. It isconfirmed thatbehaviors of the confinedring polymer with excluded volume can be understood by scaling relations based on blob picture.We also studied correspondenceto coarse grained model a branched polymer with randomly removing andadding underconstant number of bonds.
