Abstract: 双金属柱撑蒙脱石在吸附、催化领域具有广阔的应用前景。综述了近年来双金属柱撑蒙脱石制备过程中柱化剂制备、柱撑方法及其在催化和吸附领域的应用,指出制备周期较长、热稳定性和水热稳定性不高、孔径分布不均等是目前双金属柱撑蒙脱石研究中存在的主要问题。今后研究中,采用多金属柱撑,引入稀土金属,探究柱撑机制,分析结构与性能的关系,制备高性能、多功能蒙脱石材料将成为主要方向。
大学生自我领导与情绪智力关系的实证研究
An Empirical Study on the Relationship between Self-Leadership and Emotional Intelligence of College Students
 [PDF]


Advances in Psychology (AP) , 2015, DOI: 10.12677/AP.2015.58062
Abstract: 已有研究表明,对失业人员的情绪智力进行培训,结果发现情绪智力可以提高自我领导能力,从而提高自我效能感。大学生潜质的开发与其自我领导和情绪智力的关系密不可分。因此,我们认为通过对大学生的情绪智力进行培养,可以提高其自我领导能力,进而提高其个人潜质,从而更好地实现个人成长。为了验证我们的假设,我们采用大学生自我领导力问卷和情绪智力问卷(EIS)对400名大学生进行测试。研究结果表明:1) 自我领导力与情绪知觉、自身情绪管理、他人情绪管理以及情绪表达显著正相关,并且自我领导力的三个维度与情绪知觉、自身情绪管理、他人情绪管理以及情绪表达显著正相关。2) 情绪智力的两个因子——他人情绪管理与情绪知觉对自我领导力及其三个维度均具有较强的预测能力。
Existing research found that after training the emotional intelligence of the unemployed, the results show that emotional intelligence can improve self-leadership, so as to improve self-efficacy. The development of college students’ potential is closely related to self-leadership and emotional intelligence. Therefore, we believe that through the cultivation of emotional intelligence, college students can improve their self-leadership, and thus improve their personal potential and better achieve personal growth. To test our hypotheses, the College Students’ Self-Leadership Question-naire and Emotional Intelligence Questionnaire (EIS) were used to investigate 400 college students. Results show that: 1) self-leadership is significantly related to emotional perception, emotional management, emotional management of others and emotional expression. And the three dimensions of leadership are significantly related to emotional perception, emotional management, emotional management of others and emotional expression; 2) two factors of emotional in-telligence—emotional management and emotional perception of others have a strong predictive ability to self-leadership and its three dimensions.

Abstract:
采用甲基乙烯基苯基硅橡胶为基体,添加成瓷填料云母粉、补强填料气相二氧化硅制备在高温下可形成自支撑陶瓷体的烧蚀材料。通过TG-DSC测试其在室温至1000℃过程中的热性能变化。并采用FTIR和XRD分析在不同温度下燃烧产物的成分组成及其变化。结果表明,当云母粉的添加量为40份时,在1000℃时残留率约为66.21%,在600℃以上成瓷填料与硅橡胶开始发生从有机相向无机相转变的陶瓷化反应,而且随着温度的升高,成瓷化程度逐渐加深。由此简述陶瓷化机理,硅橡胶分解产生的二氧化硅与云母粉发生反应,在填料边缘处形成起桥接作用的共熔混合物,冷却后形成陶瓷化产物。
In this paper, methyl vinyl Phenyl Polysiloxane rubber (PVMQ) ablative composite filled with mica and silicone oxide was prepared. Its thermal properties were tested by TG-DSC analysis from room temperature to 1000?C. After it was fired at different temperatures, the products were analyzed by Fourier transform infrared spectrometer and X-ray diffraction. The results showed that when the addition of mica was 40, the residual rate at 1000?C was 66.21%. When the temperature was above 600?C, the filler and organic silicon rubber started to transform from organic to inorganic. As temperature rose, the extent of porcelain was gradually deepened. So the ceramic mechanism of the composite could be described that the silicon oxide decomposed from silicon rubber reacted with mica. Then eutectic mixture which had a bridge effect was formed at the edge of fillers and the ceramic products were obtained when cooled down.

Abstract:
结垢对于油气田开采、注水及排水工艺的实施危害极大。碳酸盐垢是油气田开发生产中最常见的无机垢,研制新型碳酸盐垢防垢剂,有极重大的理论和实际意义。本文采用马来酸酐、乙醇胺、丙烯酸以及次亚磷酸钠为原料,按照一定的配比,采用自由基水溶液聚合,制备出膦基PTA-AA共聚物防垢剂。利用正交试验和单因素分析方法,研究了反应条件(反应时间、反应温度、反应物配比等)对产品防垢性能的影响;采用红外光谱法表征了产品的分子结构;探讨了防垢剂加量、防垢温度、防垢时间、溶液pH值、溶液矿化度等因素对产品防碳酸钙垢性能的影响,以及防垢剂对碳酸镁垢、碳酸钡垢的防垢性能。
Scale formation does great harm to the implementation of the technology of waterflooding and dewatering in the oil-gas field development. Carbonate scale is the most common inorganic scale during the production operation. There is great theoretical and practical significance in developing advanced carbonate scale inhibitor. Maleic anhydride, ethanolamine, acrylic acid and NaH2PO2?H2O are selected as the monomers of polymerization reaction to synthetise the phosphono-PTA-AA copolymer scale inhibitors by free radical initiated aqueous system polymerization. The effects of scale inhibition performance of the polymer inhibitors on different synthetic conditions (reaction time, reaction temperature, reactant ratio etc.) are discussed by means of the single factor expe-rimental technique and the orthogonal test. The molecular structures of the polymer inhibitors are ascertained through infrared absorption spectrum method. The functioning factors of scale inhibition performance about carbonate (calcium carbonate, magnesium carbonate and barium carbonate) scale such as the dose of the scale inhibitors, evaluation temperature and time, the pH of the liquor system and the salinity are discussed.

暮色中的微光:美国联邦人身保护令制度

比较法研究 , 2014,
Abstract: 美国的联邦人身保护令制度与其他国家的人身保护令不同,是针对联邦和州法院的定罪和量刑而依被判刑人的申请发出的。这一制度以联邦权力干涉州权,对其向来争议颇多,但由于其在保护人权方面的重要作用,尽管历经风雨,却至今仍是美国司法体制的重要部分。联邦人身保护令有独特的理论基础、适用前提和运行机制,对我国当前司法体制的完善有一定的借鉴意义和参考价值,应为我们所重视。
