现代技术中的微量级热现象

近年来，在制造具有新颖结构的微型器件和材料（例如微电子器件、微机电系统和各种先进材料）方面取得了巨大的进展。这种发展使得热科学领域中的热现象。从发生在大量级结构中转移到发生在级结构中。对于更好地理解和控制能量传递而言，这种转移既提出了挑战又提供了机遇。本文从微尺寸、微结构和微时间三方面说明了上述微量级热现象。     

sBLM味觉物质生物敏感器件的研究

本文研究以琼脂糖为基的固体支撑双层脂膜（ｓＢＬＭ）对味觉物质（乙酸、盐酸喹咛、蔗糖）的响应．这三种味觉物质显著地改变了膜电位，盐酸喹咛、蔗糖对膜电阻有一定影响，脂膜对乙酸和盐酸喹咛也有良好的线性响应．检测灵敏度分别为１２μｍｏｌ／Ｌ和１．３μｍｏｌ／Ｌ，其响应特性、检测灵敏度都达到或优于现有的其它检测方法．用Ｃ６０修饰卵磷脂双层脂膜，加大了膜强度，用它检测上述三种物质，得到了相同结果．     

VIEWING URBAN DISRUPTIONS FROM A DECISION INFORMATICS PERSPECTIVE

1. Introduction Urban infrastructures are the focus of terrorist acts because, quite simply, they produce the most visible impact, if not casualties. From the September 11, 2001 (i.e., “9/11”) attack on New York City’s World Trade Center to the more recent March 11, 2004, attack on Madrid’s commuter trains, it is obvious that urban centers are indeed vulnerable to such hideous acts. A systemic or holistic approach to securing the infrastructure systems that underpin an urban center isr…     

微机的数字频率控制应用

本文介绍一种实用的微机频率自动挖制装置,它能够对要求比较稳定的频率信号进行控制,当信号频率为1H_z—1MH_z 时,控制的精度由计算机进行调节最高可达±1H_z。     

蜡梅热激蛋白基因 Cp HSP70-1的克隆、亚细胞定位与表达分析

在已构建的蜡梅花转录组数据库EST序列分析的基础上,采用 RACE技术克隆获得蜡梅热激蛋白 HSP70的cDNA序列,命名为CpHSP70‐1（GenBank登录号：KR071130）．该序列全长2520 bp ,包括1962 bp的完整开放阅读框,编码653个氨基酸蛋白序列,含有3个 HSP70家族典型基序．CpHS P70‐1蛋白与其他真核生物的HSP70蛋白具有较高的同源性,聚类分析显示其属于定位于细胞核／细胞质的蛋白．亚细胞定位结果支持该蛋白分布于细胞核的预测．利用实时荧光定量PCR对 CpHS P70‐1基因的表达特性进行分析,其在各组织中均有不同程度的表达,其中在成熟叶片中表达量最高;在不同花发育阶段呈现持续稳定的表达模式;该基因在低温和高温诱导下表达量提高,而且对高温的响应更为敏感．     

中子的构造和一种新的核的模型

中子没有电荷,但是实验方面证实了中子有磁矩。我们知道:一切磁性都是由于电荷运动而构成的。现在存在着的中子磁矩的理论是介于理论。焦起和于尔班等先后支持和发展了这个理论。费米在1949年的原子核物理课程中,认为中子实在是一种混合状态,就是说大部分时间,中子是一种磁矩为零的理想的中子,但是每秒钟的一小部分时间 t,中子转变为一个理想的质子和一个负的π介子如下式:     

The next industrial revolution: Integrated services and goods

The outputs or products of an economy can be divided into services products and goods products (due to manufacturing,construction,agriculture and mining).To date,the services and goods products have,for the most part,been separately mass produced.However,in contrast to the first and second industrial revolutions which respectively focused on the development and the mass production of goods,the next - or third - industrial revolution is focused on the integration of services and/or goods; it is beginning in this second decade of the 21st Century.The Third Industrial Revolution(TIR) is based on the confluence of three major technological enablers(i.e.,big data analytics,adaptive services and digital manufacturing);they underpin the integration or mass customization of services and/or goods.As detailed in an earlier paper,we regard mass customization as the simultaneous and real-time management of supply and demand chains,based on a taxonomy that can be defined in terms of its underpinning component and management foci.The benefits of real-time mass customization cannot be over-stated as goods and services become indistinguishable and are co-produced - as "servgoods" - in real-time,resulting in an overwhelming economic advantage to the industrialized countries where the consuming customers are at the same time the co-producing producers.     

ON SERVICES RESEARCH AND EDUCATION

1. Pertinent Background The importance of the services sector can not be overstated (Tien, 2006); it employs a large and growing proportion of workers in the industrialized nations. As reflected in Table 1, the services sector includes a number of large industries; indeed, services employment in the U.S. is at 82.1 percent, while the remaining four economic sectors (i.e., manufacturing, agriculture, construction, and mining), which together can be considered to be the “goods” sector, emplo…
