Novel Hyperbranched predominantly Alternating Copolymers Made From A Charge Transfer Complex monomer pair of p-(chloromethyl)styrene and Acrylonitrile via Controlled Living Radical Copolymerization

Summary Novel hyperbranched copolymers were successfully synthesized by the controlled charge transfer complex inimer and living radical copolymerization of p-(chloromethyl)styrene (PCMS) and acrylonitrile (AN). The resulting copolymers were characterized by SEC, NMR, FTIR, DSC and elemental analysis etc.. The influences of reaction conditions, such as the polymerization temperature, the catalyst (CuBr) concentration and the monomer ratio, on the resulting copolymers were investigated in detail. The monomer reactivity ratios were evaluated to be r_PCMS=0.937 and r_AN=0.088 respectively by the Fineman-Ross method. The higher are the polymerization temperature and the ratio of catalyst to monomer, the higher is the branching degree of the resulting copolymer. When the amount of monomer AN was used in excess than that of the monomer PCMS in the raw feed, the hyperbranched predominantly alternating copolymers HP[PCMS-co-AN] could be obtained. These hyperbranched copolymers were successfully used as functional macroinitiators to synthesize the star-shaped poly(PCMS-co-AN)/poly(MMA) block copolymers.     

核测井仪器中的磁屏蔽研究

核测井仪器受套管剩磁的影响比较严重，常常用在探测器的周围缠绕多层坡莫合金带的方法进行磁屏蔽，由于缠绕的坡莫合金圆筒不能闭合，加上缠绕过程中坡莫合金带的形变造成材料本身磁导率的下降，传统的磁屏蔽方法的效果不好。本文介绍一种简单易行、磁屏蔽效果较好的方法，实验的结果说明用电工纯铁做探测器的外壳可以达到令人满意的效果。     

Adaptive weighted outer-product learning associative memory

Associative-memory neural networks with adaptive weighted outer-product learning are proposed in this paper. For the correct recall of a fundamental memory (FM), a corresponding learning weight is attached and a parameter called signal-to-noise-ratio-gain (SNRG) is devised. The sufficient conditions for the learning weights and the SNRG's are derived. It is found both empirically and theoretically that the SNRG's have their own threshold values for correct recalls of the corresponding FM's. Based on the gradient-descent approach, several algorithms are constructed to adaptively find the optimal learning weights with reference to global- or local-error measure.

包气带中不同示踪源层条件下核素迁移对比试验

为研究不同示踪源层材料对水份运移和核素迁移的影响，开展了以石英砂和黄土分别为示踪源层载体时Sr、Nd、Ce在包气带中迁移的对比试验。试验历时470d，在两种源层条件下各取土芯样4次。试验结果表明：在喷淋强度为5mm/h、3h/d条件下，Nd和Ce无论在石英砂示踪源层还是黄土示踪源层中浓度峰位均没有明显向下迁移；对于Sr，在黄土示踪源层中，470d后其峰位向下迁移约15cm(按质心计算为10cm左右)，而从石英砂示踪源层中向下迁移不明显（按质心计算，迁移约2.7cm），只是峰位有些展宽。上述结果表明，极薄（7mm）的细石英砂层也能对非饱和入渗水产生明显屏流作用，使得核素从石英砂示踪源层中向下迁移速度减慢。
