涤纶织物氯化亚锡拔染印花工艺的研究(摘要)

由于涤纶是疏水性纤维，结构本身紧密，涤纶织物经高温高压染底色后采用氯化亚锡拔染印花必须借助于特殊的拔染印花助剂。本文研究了新拔染助剂WT－DA、有机酸、吸酸剂以及金属离子掩蔽剂对氯化亚锡拔染印花效果的影响，确定了各助剂的用量，并优化了汽蒸工艺条件，筛选了部分底色分散染料和着色染料。研究结果为：氯化亚锡拔染印花色浆由8份SnCI。，10～16份WT—DA，0．6份酒石酸，1～2份尿素，0．6～1份Na。SIO。和x份染料；印花后的汽蒸条件为190～200℃下汽蒸8～12min，相对湿度60％～70％；在此印花条件下，有9只底色染料和10只着色染料可用于拔染印花，拔染白度最高可达80％以上。

分散染料的生物降解性能

采用了[BOD5]／[CODcr]和呼吸速率曲线两种方法对6大类14种分散染料的好氧生物降解性能进行测试。实验表明，分散染料在好氧状态下大都难降解。然后又考察了这些染料的厌氧生物降解性能，发现这些染料经厌氧反应后大都变得可生化降解，并且染料结构与其降解性能之间有一定的关系。

用溶解度参数进行单偶氮分散染料的分子设计和结构筛选

本文提出了单偶氮分散染料溶解度参数的计算方法。分散染料的溶解度参数是染料结构决定染色性能的一个重要因素。有使用价值的分散染料其溶解度参数应和涤纶纤维溶解度参数相近,但这仅是必要条件,而不是充分条件。根据染料的溶解度参数,可以进行单偶氮分散染料的分子设计和初步筛选。

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.     

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     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
