The plastification modification of poly(vinyl chloride)(PVC)with the long-chain linear polyester(LP)synthesized by linear dodecanedioic acid(DC12)or tetradecanedioic acid(DC 14)with different diols is investigated.The processing characteristics,mechanical properties and extraction property of the PVC/LP blends in different solvents(xylene,cyclohexane,ethanol)were also studied in detail.All results were compared with that of the PVC plasticized with dioctyl phthalate(DOP).The results show that the molecular weight,molecular structure and loading of LP greatly influence the mechanical properties of the PVC/LP blends.The processability and the mechanical properties of PVC plasticized by LP are comparable to those of the corresponding PVC/DOP blends.However,the PVC/LP blends posses much better migration resistance property than the corresponding PVC/DOP blends,which makes the long-chain linear polyester become a very good plasticizer candidate for PVC industry.

在经典的走滑位移公式的基础上进行改进,引入断层倾角信息,使其反映了走滑断层倾角对地表形变的影响。由于断层倾角的存在使得震间位移曲线的中心是以断层面闭锁-滑动分界在地表的投影为中心,并且此处形变变化最大;公式中的倾角项表示拟合的断层倾角,体现了断层出露地表处与断层闭锁-滑动分界的整体偏移,其值往往小于近地表倾角测量值。以改进的公式作为断层剖面分析的拟合公式,应用于汶川地震前后川滇块体东边界主要走滑断
