中石油A1系统PCEDM数据模型基本实体初步研究

以基本实体部分为例，从模型结构、表关系、模型扩展3个方面对中石油A1系统PCEDM数据模型进行了分析和研究。PCEDM涉及到基本实体的表有19张，表与表之间关系复杂；涉及的数据项（字段）有500多项，各个字段都有它固定的含义。数据模型扩展有5种途径：保留预留字段、直接在原有表中加入新的字段、增加新的子表、扩展全新的顶级结构、增加新的下拉列表选项。研究结果对于深入了解PCEDM模型，更好地维护和完善PCEDM数据库具有重要意义。     

Effects of amygdala lesions on reflex facilitation and conditioned response acquisition during nictitating membrane response conditioning in rabbit.

Demonstrated that large lesions of the amygdala disrupt the maintenance of reflex facilitation of the unconditioned nictitating membrane (NM) response and slow the acquisition of conditioned NM responses in rabbits. Before behavioral training, the central nucleus of the amygdala and adjacent areas were lesioned electrolytically. In Exp 1, the lesioned animals exhibited no reflex facilitation of the unconditioned NM response at conditioned stimulus (CS)–unconditioned stimulus (UCS) intervals of 125–8,000 ms. In Exps 2 and 3, in which 1 CS–UCS interval (500 ms) was used, the lesions disrupted the maintenance of reflex facilitation but did not alter the facilitation exhibited in the 1st block of training. The lesions retarded the acquisition of conditioned NM responses when the 1,000-Hz tone CS intensity was 65 dB, but not when the intensity was 85 dB.

Microstructure of Ethylene/Propylene Random Copolymers Prepared by a Fluorinated Bis(phenoxy-imine)Ti Catalyst

Summary Living copolymerization of ethylene and propylene was catalyzed by a fluorine-containing bis(phenoxy-imine) titanium catalyst. A series of ethylene-propylene copolymers with different propylene contents were prepared and the copolymers were characterized by ¹³C-NMR, GPC and DSC. The copolymers were found to have the following characteristics: (1) Molecular weight distribution of the copolymer is rather narrow; (2) There exist only isolated propylene units distributed along the polymer chains even at propylene content as high as 14.9 mol%; (3) The distribution of ethylene sequence are not homogeneous. Insertion of propylene changes from 2,1-insertion in homopolymerization into 1,2-insertion when the preceding unit is ethylene.
