Abstract: 采用溶液燃烧法和盐助溶液燃烧法制备铜铁矿结构(ABO2)的钴酸锂(LiCoO2)系列催化剂,通过XRD、BET、ICP、XPS、H2-TPR、程序升温反应等手段对其进行了结构表征与性能评价。研究了溶液燃烧法中燃料尿素以及助剂无机盐NaCl的用量对所制备的催化剂性能影响。实验结果表明,在尿素过量100%时所制备的催化剂结晶程度及催化氧化性能较好,起燃温度达到270°C,N2的转化率达到36.9%。适量助剂NaCl的引入显著地提高了催化剂比表面积,增加了催化剂表面活性物种,增强了催化剂的氧化还原能力,进而提升催化剂的活性。其中50%质量分数的NaCl添加量制备的催化剂具有最低的碳烟起燃温度(246°C),但添加NaCl对NOx的转化率影响不大。
Ce基复合氧化物同时催化去除碳烟-NOx的性能研究

Abstract: 本研究采用柠檬酸络合法制备了Ce基复合氧化物催化剂,分别在热重分析仪(TG)和管式反应器中测试了其氧化碳烟及同时脱除NOx的催化活性;并利用XRD、BET、H2-TPR、XPS表征手段考察其结构。其中,Co0.1/CeLa0.05复合氧化物同时催化去除碳烟和NOx的性能最佳,碳烟脱除率为50%的反应温度为301 oC,N2产率为41.4%。实验结果表明,Co主要以氧化物形式均匀分散在Ce-La固溶体表面,Co3+与Co2+价态共存,离子间的变价有利于提高催化剂的氧化还原性能,有效降低了碳烟的起燃温度。La的引入增大了催化剂的比表面积,抑制了CeO2晶粒长大,进而提高了N2产率。部分La和Co形成了微量的LaCoO3,形成了更多氧空位,有利于提高催化氧化碳烟的活性。

世界科学技术-中医药现代化 , 2012,
Abstract: In the book of Treatise on Febrile Diseases and the Synopsis of the Golden Chamber, Zhang Zhongjing creatively applied the ascending and descending of spleen-stomach qi theory in the clinical practice. It had laid an important foundation for the formation and development of ascending and descending of spleen-stomach qi theory. Through the analysis of Zhang Zhongjing's three Xiexin decoction, the acrid medicinals open and bitter medicinals promote descent method has been used in the treatment of spleen and stomach diseases. It also shows the academic thought of Zhang Zhongjing's emphasis on ascending and descending of spleen-stomach qi theory. The clinical application of this thought has achieved satisfactory curative effect.
索形优化后的双向张弦梁索力静载试验设计与研究

工程力学 , 2015, DOI: 10.6052/j.issn.1000-4750.2014.07.0618
Abstract: 基于平衡荷载值确定双向张弦实腹梁结构的形状,设计了一个索形优化后的双向张弦梁整体结构索力静载试验。用万向节模拟撑杆与上弦钢梁节点,用特制花篮螺丝和改装的U型绳卡模拟拉索张拉端和锚固端,采用多点分配梁杠杆集中加载与跨中直接吊挂加载相结合的加载方案。试验结果显示,经过索网形状优化之后,竖向荷载增大到设计平衡荷载值时,双向各索索力值相近,分布均匀,明显改善受荷阶段结构中的索力分布。双向张弦梁下弦索对非对称活载尤其是二分之一跨分布形式较为敏感,可能出现边跨索力超过同级全跨荷载下的现象。
爆裂测量在金属矿床普查中的应用

地质与勘探 , 1974,
Abstract: 最近,叶尔马可夫提出的矿床普查的重砂破裂法,在地质文献中进行了广泛的讨论.不过,随后发表的一些文章多半是涉及最有利于进行爆裂声音研究的含水晶矿田中这种方法试验结果的资料.作者对鲁德内阿尔泰列宁诺哥尔斯克地区东部的斯塔尔科夫斯基矿田应用重砂爆裂法的可能性,进行了试验.斯塔尔科夫斯基矿田赋存于由中泥盆统乌斯品岩系沉积火山岩组成的北西走向的陡倾单斜中.绝大部分地区的单斜层与产于其中的矿体一起被第四系残-坡积层复盖.斯

Geographical Science Research (GSER) , 2013, DOI: 10.12677/GSER.2013.23010
Abstract:
本文构建投资环境综合评价指标体系,在此基础上运用层次分析法分析了江苏省淮安市台资企业对本地投资环境评价状况。数据来源于访谈和问卷。研究发现:台资企业对淮安基础设施建设和政府支持最为满意;对淮安的产业配套条件满意度最低;本地制度文化环境因素在一定程度上也无法达到台商要求。
This paper makes a comprehensive evaluation index system about the investment environment, and uses AHP approach to analyze how Taiwan’s enterprises evaluate local investment environment. All data comes from face-to-face interviews and questionnaires. There are some findings as follows: local infrastruc- tures and local government meet Taiwan’s enterprises well. However, local supporting industry cannot satisfy them. Moreover, local culture and institutions are also not coupling with the demands of Taiwan’s enterprises.

Abstract: Gastric cancer is one of malignant tumors with high disease incidence worldwide. Early detection and control the development from precancerous lesion of gastric cancer (PLGC) into gastric cancer is an important way to prevent and manage gastric cancer. In our previous research, the poison stasis into resistance was considered as the main pathogenesis of PLGC. Good curative effects have been achieved by the treatment with Jinguo-Weikang capsule for the purpose of detoxification and eliminating stasis. Therefore, the thought and method of syndrome differentiation and treatment by "poison stasis into resistance" theory on PLGC has been discussed.
