中药萃余液饲料添加剂的制备工艺研究

主要研究降低中药萃余液粘度和乳酸细菌发酵制备饲料添加剂工艺方法.比较3种预处理剂(预处理剂A、B和C)对萃余液粘度降低效果,在35℃保温条件下,预处理剂B和C效果最好,等比例混合处理后粘度下降到1000 mPa·s左右,流动性好.处理后的萃余液经植物乳杆菌发酵产生大量酸类物质,乳酸含量达到111 mmol/g以上,作为饲料添加剂具有中药和微生物制剂双重特性.     

当代饲料工业的核心：饲料添加剂与预混合浓缩料

饲料添加剂和预混合浓缩料是一个国家畜牧科学与饲料工业由初级到高级、由营养不平衡到平衡,发展到一定程度时的必然产物。要生产品质优、饲效好的全价配合饲料,确保营养平衡,必须首先有实力雄厚、品种完整的饲料添加剂工业和预混合浓缩饲料工业作为后盾,这是整个饲料工业的核心,也是饲料加工全过程中的关键环节。因此,其发展状况也是反映并衡量一个国家饲料工业能力与进程的重要标志。随着时代的发展,畜牧业对饲料在数量、质量与特种用途等方面的要求越来越高,原来天然饲料的季节性和营养不全等问题已不能满足现代大规模禽畜饲养的需要;同时,大规模集约化饲养也因缺乏阳光、土壤、青饲料等问题而必须补充各类营养性添加剂和为防疫与控制禽畜病疫迅速蔓延而添加各种防治、保健药剂,于是饲料添加剂便应运而     

如何正确使用饲料添加剂

饲料添加剂是为了某些特殊需要，人为地在各种配合或混合饲料中加入的具有不同用途的物质，其作用是完善和强化饲料的营养，促进家畜生长发育、预防疾病、提高饲料的利用率。有些添加剂可减少饲料贮存期的养分损失或具有增加食欲的作用。为了让广大养殖户能够了解和掌握添加剂的使用，现将有关知识作一个介绍。

国外开发的饲料特殊添加剂

随着畜牧禽鱼业的日益发展，饲料特殊添加剂的需求也日渐增长。为适应这种新形式，饲料特殊添加剂在品种和质量上不断地推陈出新。饲料特殊添加剂可以强化营养素在饲料中的含量，提高其营养价值。近年来，国外开发出许多饲料特殊添加剂。柠檬酸英国的研究人员，在每公斤仔猪饲料中添加209柠檬酸，喂养10日龄断奶的仔猪，其日增重可比不添喂柠檬酸的仔猪提高近20％。黄霉菌素德国的科学家，在猪的体重长别35kg以后，向饲料中添加黄霉菌素，其数量为仔猪每公斤饲料添加sing。饲喂后，猪的日增重可提高7％，饲料的转化率可提高5％。铜日本的畜…     

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
