基于低碳理念的鄂州市城市土地集约利用评价

结合国内外低碳土地利用的研究背景和实践,分析出不同土地利用方式碳排放效应,并对城市土地低碳化与集约化利用进行定性与定量分析,并采用鄂州市实际构建低碳理念下城市土地集约利用评价指标体系,对鄂州市2000-2013年土地利用状况进行分析评价.由此,总结鄂州市再加入低碳因素后土地集约利用的变化规律,并提出相关建议.     

从作者性别批评视角看简·爱和吕蓓卡的人物形象差异

简·爱与《名利场》中的女主角吕蓓卡是英国维多利亚时期文学中两个具有同样独立反叛意识但被作者赋予不同命运结局的女人。从作者的性别视角去解读这两个传统女性形象的本质差异,能看出男女作者对女性反抗压迫行为的不同理解和价值判断,并能更好地发掘出被别的批评视角忽略或误读的文本内涵。     

在乡土情感与政治理念之间:重评《山雨》

乡土情感与政治理念在《山雨》中形成了一种内在的张力。小说前半部分，乡土情感占优势，使作者能够充分调动丰富的乡土生活积累，作品显得浑厚沉实；后半部分，政治理念渐渐占了上风，作者驾驭起来就显得力不从心，从而使小说出现了思想与艺术的不平衡。

One step synthesis of 2-substituted 3-tri-(or di-)fluoromethyl-2-propenals in an ionic liquid

Investigation of one step synthesis of 2-substituted 3-tri-(or di-)fluoromethyl-2-propenals has been carried out using versatile aldehydes, tri- or di-fluoroacetaldehyde ethyl hemiacetal in the presence of diethylaminotrimethylsilane (DEATMS) in an ionic liquid, and it was demonstrated that this route enabled us to successfully construct 2-substituted 3-tri-(or di-)fluoromethyl-2-propenals with the high level selectivity of geometric isomers.

Spectrophotometric Study of Luminol in Dimethyl Sulfoxide–Potassium Hydroxide

The spectrophotometric study of luminol (LH₂) in dimethyl sulfoxide (DMSO), DMSO-water solutions, and alkaline DMSO and DMSO-water solutions has been done, focusing on the effect of the KOH additon on LH₂ absorption and fluorescence properties. The absorption spectra indicate an acid-base equilibrium, and the luminol dianion (L^2–) formation at 3 × 10^–4 – 2.4 × 10^–3 M KOH. The decrease of the fluorescence intensity and the variation of the excitation spectra of LH₂-DMSO-KOH solutions with KOH concentration have been similarly explained. The acid-base process is reversible. The addition of HCl to the solution with 3.0 × 10^–3 M KOH leads to an increase of the fluorescence intensity to its highest value, observed in pure DMSO. The addition of HCl to the LH₂-DMSO solution leads to the decrease of the fluorescence intensity as a result of the LH⁺ ₃ cation formation. In LH₂-DMSO-water, the fluorescence band is shifted from 405 nm to 424 nm and increased in the intensity. In the presence of KOH (in LH₂-DMSO-water-KOH solution) a new band appears, with the maximum at 485 nm and the band at 405 nm decreased. The changes in fluorescence lifetimes also evidence the different chemical species formed.     

僧帽牡蛎碱性磷酸酶功能基团的研究

采用化学修饰法研究僧帽牡蛎碱性磷酸酶活性功能基团性质.酶经0.4mmol·L-1PCMB修饰30min后活力仍然保持不变,提示巯基与酶的活力无关;用二巯基苏糖醇(DTT)对酶进行修饰,当DTT浓度达到2.5mmol·L-1时,酶活力丧失98%,表明硫 硫键与酶活力有密切的关系;以N 溴代琥珀酰亚胺(NBS)修饰酶的色氨酸残基,酶的修饰失活呈一级反应,当NBS浓度达到0.65mmol·L-1时,酶活力丧失100%,并辅以紫外吸收光谱的变化分析,表明色氨酸残基是酶催化活力所必需的;醋酸酐、马来酸酐、甲醛等氨基试剂对酶的修饰作用显示氨基是酶的必需基团.     

The spectrum of BSA(v, 3, λ; α) with α = 2,3

In this article, a kind of auxiliary design BSA^* for constructing BSAs is introduced and studied. Two powerful recursive constructions on BSAs from 3‐IGDDs and BSA^*s are exploited. Finally, the necessary and sufficient conditions for the existence of a BSA(v, 3, λ; α) with α = 2, 3 are established. © 2006 Wiley Periodicals, Inc. J Combin Designs 15: 61–76, 2007
