线性聚合物 meaning in English

linear polymer

In this paper , interpenetrating polymer networks ( ipn ) based on polysiloxane ( pdms ) and poly ( methyl acrylate ) ( pma ) were prepared by using ma monomer and two types of pdms , which viscosities were 3300pa s and 7000pa s respectively . pdms was crosslmked by tetraethyl orthosilicate
本论文制备了聚二甲基硅氧烷与聚丙烯酸甲酯的序列半互穿聚合物网络，其中聚硅氧烷为交联结构，采用粘度分别为3300pa ? s和7000pa ? s两个品种，聚丙烯酸甲酯为线性聚合物。
The fractal is a geometrical figure with self - similar symmetry , and it is an important tool for characterizing irregular structures in nature that are self - similar on certain length scales . for example , the koch curves can be viewed as a mathematical model for coastlines , percolation model can be used to mimic mixture of mental and insulator , self - avoiding walks can serve as a model for linear polymers , and rock fracture mode can stimulate the process of brittle fracture of rock , and so on
分形是具有自相似对称性的几何图形，可用来模拟自然界中在一定尺度范围内具有自相似对称性的不规则结构，如koch曲线可用来模拟海岸线，渗流模型可模拟金属绝缘体混合物，自回避无规行走模型可模拟线性聚合物，岩裂模型可模拟真实岩体的脆性破裂等。
