稻米副产品的综合利用

大米是世界人们主要的粮食之一。据联合国粮农组织统计,全世界水稻种植面积为21.6亿亩,稻谷总产量为7720亿斤。我国水稻种植面积约4.89亿亩,居世界首位,国家每年收购稻谷约一千亿斤。稻谷除生产大米以外,其副产品有稻壳、米糠、米胚和碎米。但这些副产品以往利用价值很低,没有充分发挥其经济效益。因此,这是一宗丰富的资源,综合开发利用很有前途。     

水稻有望种上月球

日本环境科学研究所进行的一项栽培实验表明，在未来，水稻有望种上月球。在月球基地上工作的宇航页，可以吃上月球大米了。在栽培实验中，日本科研人员使用了长森县特产的稻种，用钢光灯代替太阳光，并在栽培室内昼夜照射，不断地调节光的强度及温度、二氧化碳浓度等，以便提高光合作用的效率。经过80夫，就长出稻穗，100天左右稻谷已成熟，这仅为通常栽培所需160天的2／3左右，平均每平方米收获的稻谷碾成大米后为6009，与在普通水田中种植的产量基本持平，大米的米质、味也毫不逊色。这一栽培实验结果证实，水稻不仅可以在月球等宇宙空间…

壳寡糖-硒纳米植物营养调节剂的研制与应用

以壳寡糖为模板,利用复凝聚法制备了壳寡糖一硒纳米颗粒．用透射电子显微镜和Zeta—sizer电位分析仪对颗粒进行表征,发现所制备的颗粒为球状颗粒,平均粒径为100nm左右,表面带弱正电性．纳米颗粒在4℃条件下保存比较稳定,25℃以上使用有利于硒元素的释放．壳寡糖一硒纳米颗粒作为植物营养调节剂应用于水稻种植,试验表明,在水稻孕穗期和齐穗期使用均能显著提高稻谷中硒含量,分蘖期使用无明显富硒情况．孕穗期使用该营养调节剂,稻谷产量提高了8％～15％,硒含量提高了3～10倍,大米中营养物质总抗氧化能力提高了30％～60％,对硒纳米颗粒的作用机制进行了初步探讨认为,壳寡糖-硒纳米颗粒,在植物体内缓慢释放硒元素,促进了植物对硒元素的吸收,硒元素稳定富集在大米胚乳中．

褐家鼠和黄胸鼠取食行为研究

在４５ｍ２室内人工模拟自然条件下进行褐家鼠和黄胸鼠取食行为生态学特征的研究。观察结果显示，两种鼠对所提供的食物的日平均取食量和觅食时所付出的活动行为强度均无明显差异，但在日内的７时、１５时和２３时之间的摄食量和活动量的差异均极显著。当所提供的食物源有选择机会时，褐家鼠选择的平均取食量是玉米碎＞稻谷＞大米；黄胸鼠是玉米碎＞大米＞稻谷，无食物选择机会时褐家鼠的取食量是稻谷＞玉米碎＞大米；黄胸鼠是大米＞玉米碎＞稻谷。褐家鼠和黄胸鼠在寻找选择食物的过程中，通常付出的活动行为强度（量）是２３时点＞７时点＞１５时点。褐家鼠和黄胸鼠的取食行为特征表现可用“摄食时间＋食物源＋行为反应”的模式表示。同时指出鼠的取食行为与防治实践之间关系的重要性。     

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
