大量铜汞存在下银的阳极溶出伏安法测定

本文提出了在氨三乙酸(NTA)——乙二胺四乙酸(EDTA)(NH_3)体系中进行银的阳极溶出伏安法测定,排除了数千倍的汞(Ⅱ)、铜(Ⅱ)的干扰,测定下限可达0.002μg·ml~(-1),变异系数≤8%,回收率在80%～117%之间。

相对论性电子在行波磁场中的运动

相对论性电子在周期性磁场中的运动将产生自发辐射，这是产生自由电子激光的基础。本采用的行波磁场，是一种新型的周期性磁场。通过讨论要以看出，当电子通过这种磁场时也将产生自发辐射，从而说明该磁场能做为自由电子激光器的摆动器。

ERP对企业的影响

从ERP发展的历史,我们可以清楚地看到,当前,IT技术快速发展带动了管理的巨大变革,劳动工具的发展是推动社会发展的动力。而"会计"也正经历着一场新的变革。ERP(Enterprise Resources Planning)在会计领域的应用则是这场变革的一个突出趋势。ERP在会计领域的应用导致了传统会计作业模式向新模式的转移,是从企业人、财、物、产、供、销等管理的实践中总结出来,又反过来指导企业管理实践,对企业的影响意义深远。     

试论文学创作过程的逻辑起点

文章提出了创作过程逻辑起点这一理论问题，深入分析了以往我们将观察生活与情感感受视为创作过程逻辑起点的错误观点，认为文艺创作真正的逻辑起点是生命体验，而生命体验是一种物与我、虚与实、主与客、情与理等因素高度统一的心理境界。文章指出，确定文艺创作过程的逻辑起点，对于创作者把握好创作的基本精神，纠正当前创作的一些错误倾向，促进全社会文艺的繁荣具有巨大的理论价值和独到的现实意义。     

High Oil-absorptive Composites Prepared from Non-woven Fiber and Sponges with 4-tert- butylstyrene-EPDM-divinylbenzene Graft Polymer

4-tert-butylstyrene-EPDM-divinylbenzene graft terpolym-er (PBED) was prepared by graft cross-polymerization in toluene using BPO as an initiator. The gel-PBED and sol-PBED were isolated from extraction of tetrahydrofuran (THF), and then they were identified by IR spectr-oscopy. The maximum oil-absorptivity of gel-PBED produced from the optimum reaction conditions was 8420% but its swelling rate was very low. The highest oil-absorptivity of photocrosslinked sol-PBED film was 5 800%. Although its oil absorbency was not as high as gel-PBED' s, swelling rate was higher than that of gel-PBED and was suitable for commercial purpose. After swelling in oil, neither gel-PBED nor photocrosslinked sol-PBED film having high oil-absorptivity had sufficient mechanical strength to be taken out of oil wholly. As is known, composite technique is one of the useful methods for reinforcing them. Fibers, sponges and non-woven cloths were used as reinforcers or supporters in this work.
