含苯并三唑基团抗紫外辐射活性染料合成与应用性能研究

以2-(2-羟基-5-磺酸基苯基)-5-氨基-2H-苯并三唑基团为封闭基,对位酯或磺化对位酯为重氮组分,合成了黄、橙、红和蓝色4只M型活性染料,并用质谱对其结构进行了表征.用合成的染料对棉纤维染色,测定了染料的上染率和固色率,发现黄色染料的染色性能较差.与未染色的棉纤维相比,染色后棉纤维的紫外线透过率大大降低.未染色纤维的UPF值为1.3,经过黄、橙、红和蓝色染料染色的棉纤维的UPF值分别为5.9、13.7、18.8、17.5,除黄色外都达到了很好的抗紫外线效果.通过对比也发现深色织物的抗紫外线效果比浅色的好.

来自大自然的色彩

利用各种矿物颜料给服装着色的“石染”方法出现于商周时期。战国的《尚书·禹贡》中有“黑土、白土、赤土、青土、黄土”的记载,这说明我国古代先民早已对具有不同天然色彩的矿石和土壤有所认识。我国主要的矿物颜料有:红色的赭石和朱砂、黄色的石黄(雄黄和雌黄)、绿色的石绿、蓝色的石青、白色的胡粉和蜃灰(蛤蜊),以及黑色的炭黑等等。新石器时代,人们开始在应用矿物颜料的同时,使用天然的植物染料,他们将植物的花、果、根、皮、茎等放入温水中浸渍,然后从中提取染料。通过反复实践,古人终于掌握了蓝草可染蓝色、茜草可染红色、紫草可染紫…

天然蓝色素及其制取方法

水溶性天然无毒蓝色素极难制取,耐光、耐热性良好的天然蓝色素更为难得。本文介绍一种以栀子果实为原料的无毒、稳定的蓝色素制取方法。 栀于果实含有较多黄色素,自古就作黄色染料用。桅子黄色素的主要成分为京尼平糖苷。在对桅子黄色素进行研究的过程中,人们意外地发现,如果在培养基中添加栀子黄色素来培养某些微生物,则随着培养时间的推移,培养基的色泽会从黄色逐渐变成黄绿色、绿色,最终变为深蓝色。 现已揭示,转变色泽的关键是桅子色素中的京尼平糖苷受微生物生成的β—糖苷酶的水解作用变成京尼     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
