Chapter One Introduction Heat: Heat is a kind of energy, Which occurs in the transfer process. (the transferred energy contains the orderly work and disorderly heat) Energy: Concept of energy is used to specify the state of a system in thermodynamics Heat Transfer: kind of application science, is concerned with analysis of the rate of heat transfer taking place in system, or with the research on the heat-transfer reqularity

纳米给人的新希望 拥有一台只有手掌大小的超级电脑或许仍是个遥不可及的梦想,不过来自美国及荷 兰的最新研究结果,使人们朝这个目标迈出了重要的一步。 当你我可能还为着广告中那即薄又轻的笔记型电脑钦羡不己的时候,科学家早已把 目光放在纳米尺度的电子元件上。虽然早在1974年, aviram和 Ratner便提出了分子级 电子元件( molecular electronic device)的概念,直到最近几年,科学家才知道如何以碳纳 米管( carbon nanotube)、纳米线( nanowire)或有机分子建构导线、开关等单一电子元 件 而根据在几周前的 Science的一篇文章,荷兰 Delft University of Technology的ces Dekker所带领的研究小组已成功地利用碳纳米管制作了好几种数位逻辑运算电路

Chapter 9 Solids separation processes M.J. LEWIS, Department of Food Science and Technology, The University of Reading RG6 6AP 9.1 INTRODUCTION This chapter will cover the separations involving solid foods, together with the propertie

Chapter 6 Ion-exchange and electrodialysis ALISTAIR S. GRANDISON, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP, UK Ion-exchange and electrodialysis are distinct methods of separation, but can conveniently be treated together, as the basic criterion for separation in both cases is the molecular

Chapter 4 Ultrafiltration M.J. LEWIS, Department of Food Science and Technology, The University of Reading RG6 6AP 4.1 INTRODUCTION Ultrafiltration offers the opportunity to concentrate large molecular weight components without the application of heat or a change of phase. Such components are rejected

Chapter 2 Supercritical fluid extraction and its application in the food industry DAVID STEYTLER, School of Chemical Sciences, University of East Anglia, Norwich NR4 7TJ 2.1 INTRODUCTION Solvent extraction is one of the oldest methods of separation known and certainly dates back to prehistory. The science of solvent extraction has evolved accordingly over a long period of time and much progress has been made in the understanding of solvation and

Statics, Dynamics and Mechanical Engineering 1、 Introduction Mechanics Science which describes and predicts the conditions of rest or motion of bodies under the action of forces The field of Classical mechanics can be divided into three categories 1)Mechanics of Rigid Bodies

Sociological Lessons from the Titanic ll. Defining Sociology A. Is it a science? And what does this mean? B. What are social facts? Why was Durkheim's study of suicide so important? C. What do sociologists study? (What is their unit of analysis?) E. Is sociology micro or macro? Do they study the big picture or the little picture? F. Is sociology global? In what sense?
