Part 1: Key design principles and designing

in context

Regeneration Director Vermont House 375 Stanley Road Bootle L20 3RY

1. Introduction

a. Good design is important in order to

improve the physical environment of

an area while also preserving and

enhancing its natural beauty and

amenity. Sefton is committed to

delivering high standards of design

in development to ensure its positive

contribution to the local environment

and a better quality of life of all those

living, working in or visiting the area.

b. This guidance note explains how you

should apply the draft Unitary

Development Plan (UDP) Policy

DQ1 on the design of development.

It sets out the key principles on

which we will assess the quality of

your proposed development.

c. Part 1 gives key principles on design

before setting out those principles

that are most relevant to the design

of development in Sefton. This part

of the supplementary planning

guidance is accompanied by

Settlement Character Plans that set

out the unique character G of each

settlement in the Borough. This will

help you develop a design that is in

context G with the surrounding area.

Part

2

sets out the principles on

which the site design, layout and

access will be assessed.

Part

3 sets out the principles on

which the design of individual

buildings and structures will be

assessed.

d. All of this guidance note should be

taken into account in the design of

your proposed development. The

guidance should be used to carry out

a site appraisal on the existing

conditions and features of the site,

and to prepare a site layout and

landscape plan for your

development. Where you are

proposing a major development, or a

development in a sensitive location,

these should be submitted in a

design statement along with the

planning application.

e. Some of the technical terms in this

guidance are explained in a glossary

at the back of the Design SPG.

These terms are indicated by a ‘G’,

the first time they appear in each

section of the SPG.

2. Definition of design

a. For the purpose of the UDP draft

DQ1, ‘design’ refers to both the

physical appearance of buildings or

spaces and their use. The

relationship between how a place

looks and how it works is called

‘urban design’, (although its

principles apply to all developments

whether in the town or countryside).

3. The importance of

good design

a. Good design creates attractive

places that have a distinctive

character, and are safe and

accessible to all. This can help to

achieve sustainable development G,

which is development that helps to

achieve a better quality of life for

everyone, now and for generations

to come (See Pt.4: Sustainability

Checklist).

b. In considering sustainable

development we need to think about

promoting greener lifestyles, for

example, using energy efficiently,

catering for a mix of uses and

providing a choice of transport.

These considerations can add

environmental, social and economic

value to proposals.

4. The Principles of Good

Design

a. Well-designed places tend to have a

number of characteristics in

common from which we can draw

general principles. These principles

are that any new development

should:

? Reinforce and enhance the

character of the local area; ? create positive landmark features

and protect or improve existing views to reinforce the legibility G of town centres. This means the degree to which a place can be easily understood and traversed.

? be accessible to pedestrians by

fitting in with and improving

existing patterns of movement and circulation;

? fit in with and reinforce local

patterns of development, movement and architectural and landscape character to improve the

appearance and identity of local centres; and ? use clear and easily understood

layouts by providing recognisable routes, landmarks and junctions;

? improve the quality, character,

definition and safety of streets and public spaces;

? maintain and enhance landscaping

quality along main routes.

? included mixed-use (i.e. a number

of different land-uses e.g. shops, homes)

6. Settlement Character

plans

? be adaptable so it can change as

peoples needs change.

a.

Sefton is made up of individual

settlements. Within each settlement there are areas with different

characters to reflect different land-uses, types of buildings and different landscapes or periods of development.

b.

In your development you should consider all these principles, although some will be more

important than others depending on the individual circumstances of your site and the type of development you are proposing.

b.

The settlement character plans (which you can get from us) describe the main elements that make up the character and physical structure of each settlement. They also set out the design features that you need to address so your development reinforces and

enhances the character of the area, and creates good urban design. c.

The following general guidance, and guidance in the rest of this guidance note, is based on the general principles shown above.

5. General design

guidance for

development in Sefton

c.

Use the character plans as the starting point for carrying out a

detailed appraisal of your site and its context.

a.

The following urban design criteria will apply to all development proposals in Sefton, including landscaping work s. These are based on our findings from a

borough-wide urban design survey.

d.

Understanding the environment your site is in, including the appearance of surrounding buildings and

landscapes as well as how land is used and its accessibility, will help you to produce a high quality design, which is specific to your site .

b. We expect your development to:

? follow established building lines or

boundaries to define and enclose routes and spaces;

e.

Use the relevant character plan and supporting guidance to make sure your proposed development is appropriate for the local area.

? be of an appropriate size,

proportion, form G and use for their location;

f. If, in the relevant character plan,

there is a lack of positive features to

influence the design of your

development, you should apply the

basic urban design principles and

create a development with its own

character. Equally, if the appraisal

of your site and its context identifies

negative features, the design you

choose must try to overcome these

problems.

7. Design

Statements

a. According to Section 3 of the draft

UDP Policy DQ1, certain

developments such as major

developments on significant sites or

sites in sensitive locations, require a

design statement in addition to a

planning application. In general, we

need design statements for:

? major development sites identified in the Unitary Development Plan;

? housing developments with more than five homes;

? sites next to main routes or

junctions, or within town centres or ‘areas of local distinctiveness’, as

shown on the settlement character

plans; ? sites within or next to a

conservation area, a listed building

or an ancient monument;

? sites within or next to the green belt, the coast or important green

spaces; and

? sites where a development brief has been prepared.

b. Your design statement should set

out a clear and concise analysis of

the site and its surroundings. It

must explain the principles behind

your design and how this relates to

and enhances the character of the

area, and contributes to sustainable

development.

c. Your design statement should

include the site appraisal referred to

in draft policy DQ1, and explained in

Part 2: Site design, layout and

access. Further advice on the

preparation of a design statement

and any additional information you

will need is given in the separate

design advice note on design

statements.

e. We may refer applications that are

significant to the whole borough or

region to the Commission of

Architecture and the Built

Environment (CABE) for comment.

We will do this with your co-

operation wherever possible.

1. Introduction

2. Assessment of the Local Character of Bootle

a.

We have produced Settlement Plans to describe the main features that make up the character of each of the five urban districts in Sefton. The districts are based on the existing settlements of Bootle, Crosby,

Maghull, Formby and Southport. The Settlement Plans consist of these guidance notes and the

accompanying map, available from the planning department.

a. The development of Bootle is largely

due to the extension of the docks northwards from Liverpool. The first stages of development in the mid-19th century was rows of large

terraced houses and detached villas for merchants. As the docks expanded, this led to the development of warehouses,

industrial buildings and houses back from the waterfront. This produced a grid network of streets (main roads overlaid with a finer network of residential streets). This grid

network remains largely the same despite the development since the second world war. b.

The Settlement Plans identifies the distinct character areas within each district, and are based on patterns of land use, building type and period of development. Physical features such as key routes, landmarks, junctions and boundaries are shown. The plans also indicate the locations where Design Statements must be sent in with a planning application.

b. Seaforth, the area between Bootle

and Crosby, is characterised by larger Victorian and Edwardian

terraced houses. The historic centre on Seaforth Road retains evidence of its form G before 1850, although its original character and structure has been damaged by the construction of the A5036 road corridor.

Litherland, separated from Bootle by the A5036, is primarily residential in its character and form. The majority of the properties are either late 19th Century or inter-war detached and semi-detached set in larger plots within a curvilinear G grid layout with generous tree planting. c.

The plans should be used to develop a scheme that responds positively to its context G . Each plan also includes area-based design guidance that addresses specific issues relevant to that settlement area and must be

taken into account when developing a scheme.

d.

This guidance note and the

settlement plans are based on an Urban Design Study of Sefton. The tables below refer to information gathered by the study.

c. Orrell (developed between the First

and Second World Wars) and

Netherton (developed in the1960’s and 70’s) are large areas of council housing whose form reflects the current approach to housing layout and design at that time. Orrell is strongly influenced by the Garden City movement G with terraces and semi-detached houses arranged in a spacious curvilinear grid layout;

Netherton shows the influence of the Radburn G approach with housing grouped around walkways and parking areas.

e.

Some of the technical terms in this guidance are explained in a glossary at the back of the Design SPG.

These terms are indicated by a ‘G ’, the first time they appear in each section of the SPG.

5. Areas of Local Distinctiveness

a. Areas of Local Distinctiveness are

more closely defined areas within the

district that have either retained their

original character or illustrate a

distinct or important period of growth

within a particular settlement.

Achieving a high standard of design

will be particularly important in these

areas in order to preserve or enhance

their established character.

b. The following have been defined as

Areas of Local Distinctiveness within

the area covered by Bootle

Threats to character ? ‘Modernisation’ of properties could lead to loss of original detailing.

? Loss or inappropriate replacement of boundary treatment.

? Loss of landscape features.

6. Design Guidance

a. We have developed the following

guidance from an assessment of the

strengths and weaknesses of the area

as set out in the above tables. The

guidance gives more detailed advice to

support the policies set out in the UDP

and the Borough-wide guidance in Part

1 of the Design SPG.

b. The guidance is in two parts, firstly

there is district–wide advice relating to

the Broad Character Areas; secondly

there is more detailed guidance relating to the Areas of Local Distinctiveness.

Here a high standard of design is

required to preserve or enhance their

established character.

District-wide Guidance

c. Within the Bootle Settlement Character

Plan area development proposals will

need to:

Establish a positive relationship with Dunningsbridge Rd. Stanley Rd &

Derby Rd. corridors by improving

quality of enclosure, landscaping and the creation of a strong public face to them. Landmarks should reinforced

or created at key junctions.

Strengthen or create pedestrian linkages between the individual

elements of Netherton Local Centre & Switch Island Retail Park & their

surrounding housing areas.

Respect and enhance the townscape qualities of the Seaforth Local Centre through the scale G, massing and

detailed design of schemes.

Development should follow historic

building lines to maintain a

continuous & active built frontage G to Seaforth Rd. Buildings that make a

positive contribution to the

townscape should be retained.

Contribute towards the enhancement of public spaces within Netherton &

Seaforth Local Centres and the

residential areas of Netherton.

Ensure that existing levels of

permeability G and active frontage G

are maintained where existing

residential areas are redeveloped. Policies relating to Bootle Town Centre will be shown in a separate SPG (not yet available).

Local Distinctiveness Guidance

d. In addition to the above guidance the

following guidance is applicable to

proposals within the following Areas

of Local Distinctiveness.

Port of Liverpool:

e. Development proposals, including

conversions and changes of use, will

need to:

Protect or reinforce important views, vistas & landmarks in relation to the

distinctive skyline of the docks and

views over Mersey.

Terraced Housing west of Bootle Gasworks & Cambridge Road Housing:

f. Development proposals, including

conversions and changes of use, will

need to:

Retain or reinstate small scale details to properties including boundary

treatments, chimney stacks &

original windows.

Maintain or reinforce hierarchy of building form G, scale & detailing.

Contribute towards hard landscaping improvements to the streetscene.

Retain commercial uses to Stanley Rd. & Hawthorne Rd. frontages. The

use of upper floors for commercial or residential use will be encouraged.

Litherland Park & Wilson’s Lane, Litherland

g. Development proposals, particularly in

respect to infill development G and

extensions to dwellings, will need to: Respect the scale, massing & use of materials of adjacent properties.

Particular care should be taken in

respecting floor to ceiling heights of

Victorian/Edwardian properties in

Litherland Park.

Use gables, bays or other features to create an appropriate level of three

dimensional interest to elevations,

break up mass of building and give

vertical and horizontal emphasis.

Create variety and interest in roofline including use of chimney stacks.

Retain or reinstate period detailing, features or original materials

including the retention of boundary

walls, gateposts or other external

features.

Ensure that car parking is designed to have a minimal visual impact on

the street frontage.

Maintain level of tree coverage within street scene.

Orrell Park

h. Development proposals, particularly in

respect to extensions to or the

remodelling of dwellings, will need to: Respect the scale and massing of adjacent properties.

Respect original detailing to

dwellings in terms of scale,

proportion & the type & finish of

materials.

Retain or reinstate original boundary treatments, in particular privet

hedges.

Ensure that car parking is designed to have a minimal visual impact on

the street frontage.

Contribute to the creation of a

coherent design theme, including

hard and soft landscaping for areas

adjacent to highway.

1. Introduction

2. Assessment of the Local

Character of Crosby

a. We have produced Settlement Plans

to describe the main features that make up the character of each of the five urban districts in Sefton. The districts are based on the existing settlements of Bootle, Crosby, Maghull, Formby and Southport. The Settlement Plans consist of these guidance notes and the accompanying map, available from the planning department. a. The historical pattern of development

in Crosby is characterised by the

growth of a series of individual

settlements running north from Bootle

along the coast. These developed

around stations on the Liverpool –

Southport railway line. This pattern of

development was a response to the

northward expansion of the docks and

the associated growth of Liverpool

and Bootle from the middle of the 19th

Century onwards.

b. The Settlement Plans identifies the

distinct character areas within each

district, and are based on patterns of land use, building type and period of development. Physical features such as key routes, landmarks, junctions and boundaries are shown. The plans also indicate the locations where Design Statements must be prepared and submitted with a planning application. b. The general pattern of development is

characterised by the use of a

permeable G grid structure varying

from the tight, regular grid-iron layout G

of Waterloo to the more curvilinear G,

irregular and spacious layout of

Blundellsands.

c. Along the main routes that link the

centres of growth there is significant

evidence of Victorian and Edwardian

ribbon development G. This two and

three storey development contains a

mix of shops and homes. Despite

development blurring the separation

between the groups, the settlements

retain a degree of distinctiveness,

particularly in the case of Hightown

and Little Crosby.

c. The plans should be used to

develop a scheme that responds

positively to its context G. Each plan

also includes area-based design

guidance that addresses specific

issues relevant to that settlement area

and must be taken into account when

developing a scheme.

d. This guidance note and the

settlement plans are based on an Urban Design Study of Sefton. The tables below refer to information gathered by the study. 3. Broad Character Zones (Residential)

互联网起源-发展-历程-历史

国际互联网,始于1969年的美国,又称因特网,是全球性的网络,是一种公用信息的载体,是大众传媒的一种。互联网是由一些使用公用语言互相通信的计算机连接而成的网络,即广域网、局域网及单机按照一定的通讯协议组成的国际计算机网络。组成互联网的计算机网络包括小规模的局域网(LAN)、城市规模的区域网(MAN)以及大规模的广域网(WAN)等等。这些网络通过普通电话线、高速率专用线路、卫星、微波和光缆等线路把不同国家的大学、公司、科研部门以及军事和政府等组织的网络连接起来。 各行各业的人需要运用互联网来工作、生活、娱乐、消费,互联网本身是一个产业,同时它也带动了其他所有的产业的发展。计算机网络仅仅是传输信息的媒介,是一个狭义的硬件网。而互联网是个广义的网,它的精华则是它能够为你提供有价值的信息和令人满意的服务。互联网也是一个面向公众的社会性组织。世界各地数以万计的人们可以利用互联网进行信息交流和资源共享。互联网是人类社会有史以来第一个世界性的图书馆和第一个全球性论坛。它为用户提供了高效工作环境,入网的电脑终端可以调阅各种信息资料。人民可以通过互联网进行娱乐与消费,听歌、看视频、购物。随着通讯技术的发展,上网终端已经不限于台式电脑和移动电脑,智能手机、平板电脑、掌上游戏机,甚至谷歌开发出来的眼镜、手表都可以上网。网络无处不在,网络无所不能。 一、从互联网的发展历程来看,从最初的ARPANET到如今的万维网。 1、互联网的起源。这一时期推动互联网发展的推动力是美国的冷战思维。 作为对前苏联1957年发射的第一颗人造地球卫星Sputnik的直接反应,以及由苏联的卫星技术潜在的军事用途所导致的恐惧,美国国防部组建了高级研究项目局(ARPA)。当时,美国国防部为了保证美国本土防卫力量和海外防御武装在受到前苏联第一次核打击以后仍然具有一定的生存和反击能力,认为有必要设计出一种分散的指挥系统:它由一个个分散的指挥点组成,当部分指挥点被摧毁后,其它点仍能正常工作,并且这些点之间,能够绕过那些已被摧毁的指挥点而继续保持联系。为了对这一构思进行验证,1969 美国国防部委托开发ARPANET,进行联网的研究。同年,美军在ARPA制定的协定下将美国加利福尼亚大学、斯坦福大学研究学院加利福尼亚大学和犹他州大学的四台主要的计算机连接起来。这个协定由剑桥大学的BBN和MA执行,在1969年12月开始联机。它的目的就是重新树立美国在军事科技应用开发方面的领导地位。当时的网络传输能力只有50Kbps,按标准来说就是非常的低。 从1970年开始,加入ARPANET的节点数不断的增加。当时ARPANET使用的是NCP协议,它允许计算机相互交流,从1970年开始,加入ARPANET的节点数不断的增加。最初的NCP 协议下的ARPANET上连接了15个节点共23台主机。到1972年时,ARPANET网上的网点数已经达到40个,这40个网点彼此之间可以发送小文本文件(当时称这种文件为电子邮件,也就是我们现在的E-mail)和利用文件传输协议发送大文本文件,包括数据文件(即现在Internet中的FTP),同时也发现了通过把一台电脑模拟成另一台远程电脑的一个终端而使用远程电脑上的资源的方法,这种方法被称为Telnet。由此可看到,E-mail,是Internet 上较早出现的重要工具,特别是E-mail仍然是目前Internet上最主要的应用。但在NCP 协议下,目的地之外的网络和计算机却不分配地址,从而限制了未来增长的机会。但无论如何,ARPANET成为了第一个简单的纯文字系统的Internet。可以说,最早促使互联网最初起源的推动力是冷战时期的军备角力思维。 2、TCP/IP协议的产生。 由于最初的通信协议下对于节点以及用户机数量的限制,建立一种能保证计算机之间进行通信的标准规范(即“通信协议”)显得尤为重要。1973年,美国国防部也开始研究如何实现各种不同网络之间的互联问题。作为Internet的早期骨干网,ARPAnet的试验并奠定了Internet存在和发展的基础,ARPAnet在技术上的另一个重大贡献是TCP/IP协议簇的

半导体封测行业发展趋势分析

半导体封测:走向世界舞台,前十占据三家 1 半导体封测发展历程:并购开打国际市场 封测其实包括封装和测试两个步骤,在现在生产中,由于产业规划基本合并在一起。所以封装测试就成为整个集成电路生产环节中最后一个过程。封测整体门槛较低,需要一定资金形成规模效应,对成本较为敏感,需要长期验证建立客户关系,是集成电路产业链中最容易突破的一环,但也是最重要的环节。因为是产品质量最后一关,若没有良好的封测,产品PPM(百万颗失效率)过高,导致客户退回或者赔偿是完全得不偿失的。 图表5一般芯片成本构成 5%

我国封测行业规模继续保持快速增长,近两年增速放缓。根据中国半导体协会数据,2019年我国半导体封测市场达2350亿元,同比增长7.10%。2012年我国封测市场销售额为1036亿元,七年以来我国半导体封测市场年复合增速为12.4%,增速保持较高水平。随着5G应用、AI、IoT等新型领域发展,我国封测行业仍然有望保持高增长。 图表6 我国封测行业年销售额及增速 2019年全球封测业前十市占率超过80%,市场主要被中国台湾、中国大陆、美国占据。中国台湾日月光公司(不含矽品精密)营收达380亿元,居全球半导体封测行业第一名,市场占有率达20.0%。美国安靠、中国长电科技分居二、三位,分别占14.6%、 11.3%。前十大封测厂商中,包含三家中国大陆公司,分别为长电科技、通富微电、华 天科技。

控制系统发展综述

控制系统发展综述 1 引言 控制系统其实从20世纪40年代就开始使用了,早期的现场基地式仪表和后期的继电器构成了控制系统的前身。现在所说的控制系统,多指采用电脑或微处理器进行智能控制的系统,在控制系统的发展史上,称为第三代控制系统,以PLC和DCS为代表,从70年代开始应用以来,在冶金、电力、石油、化工、轻工等工业过程控制中获得迅猛的发展。从90年代开始,陆续出现了现场总线控制系统、基于PC的控制系统等,本文将简要介绍各种常见的控制系统,并分析控制系统的演进过程和发展方向。 2 集散控制系统DCS 2.1 DCS的发展历程 70年代中期,由于设备大型化、工艺流程连续性要求高、要控制的工艺参数增多,而且条件苛刻,要求显示操作集中等,使已经普及的电动单元组合仪表不能完全满足要求。在此情况下,业内厂商经过市场调查,确定开发的DCS产品应以模拟量反馈控制为主,辅以开关量的顺序控制和模拟量开关量混合型的批量控制,它们可以覆盖炼油、石化、化工、冶金、电力、轻工及市政工程等大部分行业。 1975年前后,在原来采用中小规模集成电路而形成的直接数字控制器(DDC)的自控和计算机技术的基础上,开发出了以集中显示操作、分散控制为特征的集散控制系统(DCS)。由于当时计算机并不普及,所以开发DCS应强调用户可以不懂计算机就能使用DCS;同时,开发DCS还应强调向用户提供整个系统。此外,开发的DCS应做到与中控室的常规仪表具有相同的技术条件,以保证可靠性、安全性。 在以后的近30年间,DCS先与成套设备配套,而后逐步扩大到工艺装置改造上,与此同时,也分成大型DCS和中小型DCS两类产品,使其性能价格比更具有竞争力。DCS产品虽然在原理上并没有多少突破,但由于技术的进步、外界环境变化和需求的改变,共出现了三代DCS产品。1975年至80年代前期为第一代产品,80年代中期至90年代前期为第二代产品,90年代中期至21世纪初为第三代产品。 2.2 DCS控制站 DCS系统中,控制站作为一个完整的计算机,它的主要I/O设备为现场的输入、输出处理设备,以及过程输入/输出(PI/O),包括信号变换与信号调理,A/D、D/A转换。控制站是整个DCS的基础,它的可靠性和安全性最为重要,死机和控制失灵的现象是绝对不允许的,而且冗余、掉电保护、抗干扰、构成防爆系统等方面都应很有效而可靠,才能满足用户要求。 关于DCS控制站的系统软件,包括实时操作系统、编程语言及编译系统、数据库系统、

互联网发展历程

互联网发展历程 1969年 互联网始于1969年,是美军在ARPA(阿帕网,美国国防部研究计划署)制定的协定 下将美国 互联网 西南部的大学UCLA(加利福尼亚大学洛杉矶分校)、Stanford ResearchInstitute(斯坦福大学研究学院)、UCSB(加利福尼亚大学)和UniversityofUtah(犹他州大学)的四台主要的计算机连接起来。这个协定有剑桥大学的BBN和MA执行,在1969年12月开始联机。到1970年6月,MIT(麻省理工学院)、Harvard(哈佛大学)、BBN和SystemsDevelopmentCorpinSantaMonica(加州圣达莫尼卡系统发展公司)加入进来。到1972年1月,Stanford(斯坦福大学)、MIT’sLincolnLabs(麻省理工学院的林肯实验室)、Carnegie-Mellon(卡内基梅隆大学)和Case-WesternReserveU加入进来。紧接着的几个月内NASA/Ames(国家航空和宇宙航行局)、Mitre、Burroughs、RAND(兰德公司)和theUofIllinois(伊利诺利州大学)也加入进来。1983年,美国国防部将阿帕网分为军网和民网,渐渐扩大为今天的互联网。之后有越来越多的公司加入。1968年,当参议员TedKennedy(特德.肯尼迪)听说BBN赢得了ARPA协定作为内部消息处理器(IMP)”,他向BBN发送贺电祝贺他们在赢得“内部消息处理器”协议中表现出的精神。互联网最初设计是为了能提供一个通讯网络,即使一些地点被核武器摧毁也能正常工作。如果大部分的直接通道不通,路由器就会指引通信信息经由中间路由器在网络中传播。最初的网络是给计算机专家、工程师和科学家用的。那个时候还没有家庭和办公计算机,并且任何一个用它的人,无论是计算机专家、工程师还是科学家都不得不学习非常复杂的系统。以太网-----大多数局域网的协议,出现在1974年,它是哈佛大学学生BobMetcalfe(鲍勃.麦特卡夫)在“信息包广播网”上的论文的副产品。这篇论文最初因为分析的不够而被学校驳回。后来他又加进一些因素,才被接受。由于TCP/IP体系结构的发展,互联网在七十年代的时候迅速发展起来,这个体系结构最初是有BobKahn(鲍勃.卡恩)在BBN提出来的,然后由史坦福大学的Kahn(卡恩)和VintCerf(温特.瑟夫)和整个七十年代的其他人进一步发展完善。八十年代,DefenseDepartment(美国国防部)采用了这个结构,到1983年,整个世界普遍采用了这个体系结构,从而得到了全世界的认可。1978年

半导体材料与器件发展趋势总结 材料是人类社会发展的物质基础与先导。每一种重大新材料的发现和应用都把人类支配自然的能力提高到一个全新的高度。材料已成为人类发晨的里程碑。本世纪中期单晶硅材料和半导体晶体管的发明及其硅集成电路的研究成功,导致了电子工业大革命。使微电子技术和计算机技术得到飞速发展。从20世纪70年代的初期,石英光纤材料和光学纤维的研制成功,以及GaAs等Ⅲ-Ⅴ族化合物的材料的研制成功与半导体激光器的发明,使光纤通信成为可能,目前光纤已四通八达。我们知道,每一束光纤,可以传输成千上万甚至上百万路电话,这与激光器的发明以及石英光纤材料、光纤技术的发展是密不可分的。超晶格概念的提出MBE、MOCVD先进生长技术发展和完善以及超品格量子阱材料包括一维量子线、零维量子点材料的研制成功。彻底改变了光电器件的设计思想。使半导体器件的设计与制造从过去的杂质工程发展到能带工程。出现了以“电学特性和光学特性的剪裁”为特征的新范畴,使人类跨入到以量子效应为基础和低维结构为特征的固态量子器件和电路的新时代,并极有可能触发新的技术革命。半导体微电子和光电子材料已成为21世纪信息社会的二大支柱高技术产业的基础材料。它的发展对高速计算、大容量信息通信、存储、处理、电子对抗、武器装备的微型化与智能化和国民经济的发展以及国家的安全等都具有非常重要的意义。 一、几种重要的半导体材料的发展现状与趋势 1.硅单晶材料 硅单晶材料是现代半导体器件、集成电路和微电子工业的基础。目前微电子的器件和电路,其中有90%到95%都是用硅材料来制作的。那么随着硅单晶材料的进一步发展,还存在着一些问题亟待解决。硅单晶材料是从石英的坩埚里面拉出来的,它用石墨作为加热器。所以,来自石英里的二氧化硅中氧以及加热器的碳的污染,使硅材料里面包含着大量的过饱和氧和碳杂质。过饱和氧的污染,随着硅单晶直径的增大,长度的加长,它的分布也变得不均匀;这就是说材料的均匀性就会遇到问题。杂质和缺陷分布的不均匀,会使硅材料在进一步提高电路集成度应用的时候遇到困难。特别是过饱和的氧,在器件和电路的制作过程中,它要发生沉淀,沉淀时的体积要增大,会导致缺陷产生,这将直接影响器件和电路的性能。因此,为了克服这个困难,满足超大规模集成电路的集成度的进一步提高,人们不得不采用硅外延片,就是说在硅的衬底上外延生长的硅薄膜。这样,可以有效地避免氧和碳等杂质的污染,同时也会提高材料的纯度以及掺杂的均匀性。利用外延方法,还可以获得界面非常陡、过渡区非常窄的结,这样对功率器件的研制和集成电路集成度进一步提高都是非常有好处的。这种材料现在的研究现状是6英寸的硅外延片已用于工业的生产,8英寸的硅外延片,也正在从实验室走向工业生产;更大直径的外延设备也正在研制过程中。 除此之外,还有一些大功率器件,一些抗辐照的器件和电路等,也需要高纯区熔硅单晶。区熔硅单晶与直拉硅单晶拉制条件是不一样的,它在生长时,不与石英容器接触,材料的纯度可以很高;利用这种材料,采用中子掺杂的办法,制成N或P型材料,用于大功率器件及电路的研制,特别是在空间用的抗辐照器件和电路方面,它有着很好的应用前景。当然还有以硅材料为基础的SOI材料,也就是半导体/氧化物/绝缘体之意,这种材料在空间得到了广泛的应用。总之,从提高集成电路的成品率,降低成本来看的话,增大硅单晶的直径,仍然是一个大趋势;因为,只有材料的直径增大,电路的成本才会下降。我们知道硅技术有个摩尔定律,每隔18个月它的集成度就翻一番,它的价格就掉一半,价格下降是同硅的直径的增大密切相关的。在一个大圆片上跟一个小圆片上,工艺加工条件相同,但出的芯片数量则不同;所以说,增大硅的直径,仍然是硅单晶材料发展的一个大趋势。那我们从提高硅的

(新)企业组织结构的发展与变化

中国管理科学院院士蒋景楠:企业组织结构的发展与变化企业组织的产生 企业的出现是近二三百年的事,它是社会生产力发展到一定水平的结果,是商品生产与商品交换的产物,在资本主义社会之前,也有一些手工业作坊,它们并未形成社会的基本经济单位,从严格意义上讲,这些手工业作坊不能称之为企业。因为那时自给自足的自然经济占统治地位,社会生产和消费主要是以家庭为经济单位。尽管有些作坊具有一定生产规模和一定量的劳动者,但生产的产品只是为部落、家族、奴隶主、封建皇室享用,不是为了进行商品交换,不发生经营活动,故也不是企业。只是到了资本主义社会,随着社会生产力的提高和商品生产的发展,社会的基本经济单位才发生根本的变化,才产生本来意义上的企业。 企业的初期形态,主要是由资本所有者雇佣许多工人,使用一定的生产手段,在分工协作的基础上从事商品的生产和交换而形成的。由于企业这种组织形式能较好地应用当时社会的科学技术(主要是机器、设备),能显著地提高劳动生产率,能大幅度降低成本,带来高额利润,能集中地大量地生产商品,满足日益增长的社会需求,因而社会生产力有了长足的发展,企业就是在这样一个漫长的演变过程中逐渐成为社会的基本经济单位的。 企业组织结构的演进 随着企业的产生和发展及领导体制的演变,企业组织结构形式也经历了一个发展变化的过程。迄今,企业组织结构主要的形式有:直线制,职能制,直线-职能制,事业部制,模拟分权制,矩阵结构等。 ——直线制 直线制是一种最早也是最简单的组织形式。它的特点是企业各级行政单位从上到下实行垂直领导,下属部门只接受一个上级的指令,各级主管负责人对所属单位的一切问题负责。厂部不另设职能机构(可设职能人员协助主管人工作),一切管理职能基本上都由行政主管自己执行。直线制组织结构的优点是:结构比较简单,责任分明,命令统一。缺点是:它要求行政负责人通晓多种知识和技能,

【发展战略】我国半导体产业的现状和发展前景

五、半导体篇 ——我国半导体产业的现状和发展前景 电子信息产业已成为当今全球规模最大、发展最迅猛的产业,微电子技术是其中的核心技术之一(另一个是软件技术)。现代电子信息技术,尤其是计算机和通讯技术发展的驱动力,来自于半导体元器件的技术突破,每一代更高性能的集成电路的问世,都会驱动各个信息技术向前跃进,其战略地位与近代工业化时代钢铁工业的地位不相上下。 当前,世界半导体产业仍由美国占据绝对优势地位,日本欧洲紧随其后,韩国和我国台湾地区也在迅速发展。台湾地区半导体工业已成为世界最大的集成电路代工中心,逐步形成自己的产业体系。 我国的微电子科技和产业起步在50年代,仅比美国晚几年。计划经济时期,由于体制的缺陷和其间10年“文革”,拉大了和国际水平的差距。进入80年代,我国面对国内外微电子技术的巨大反差和国外对我技术封锁,我们没有能够在体制和政策上及时拿出有效应对措施。国有企业无法适应电子技术的快节奏进步,国家协调组织能力下降,科研体制改革缓慢,以致1980~1990年代我国自主发展半导体产业的努力未获显著效果。 “市场‘开放’后,集成电路商品从合法、不合法渠道源源涌入,集成电路所服务的终端产品,以整机或部件散装的形式,也大量流入,但人家确实考虑到微电子的战略核心性质,死死卡住生产集成电路的先进设备,不让进口,在迫使我们落后一截,缺乏竞争力的同时,又时刻瞄准我们科研与生产升级的潜力,把我们的每一次进步扼杀在萌芽状态,冲垮科技能力,从外部加剧我们生产与科研的脱节,迫使我们不得不深深依赖他们。……我们的产业环境又多多少少带有计划色彩,不能很快与国际接轨,其中特别是对微电子产业发展有重大影响的企业制度、资本市场、税收政策、科研体制等,又不适应市场经济要求,使得我们在国际竞争中缺乏活力”。1 20世纪90年代,我国半导体产业的增长速度达到30%以上,但其规模仅占世界半导体子产业的1%,仅能满足大陆半导体市场的不足10%。即使“十五”期间各地计划的项目都能如期实施,到2005年,我国半导体产业在世界上的份额,顶多占到2%~3%。自己的设计和制造水平和国际先进水平的差距很大,企业规模小、重复分散、缺乏竞争力,基本上是跨国公司全球竞争战略的附庸,自己的产业体系还没有成形。 我国半导体产业如此落后的现状,使得我国的经济、科技、国防现代化的基础“建筑在沙滩上”。在世界微电子技术迅猛发展的情况下,我国如不努力追赶,就会在国际竞争中越来越被动,对我国未来信息产业的升级和市场份额的分配,乃至对整个经济发展,都可能造成十分不利的影响。形势逼迫我国必须加快这一产业的发展。“十五”计划中,加快半导体产业的发展被放在重要地位,这是具有重大意义的。 发展中国家要追赶国际高科技产业的步伐,一般都会面临技术、资金、管理、市场的障碍。高科技的产业化是一个大规模的系统工程,需要科研和产业的紧密结合,以及各部门的有效协调,而这些都不是单个企业所能跨越得过去的。在市场机制尚未成熟到有效调动资源的情况下,高层次的组织协调和扶持是必需的。构建具有较高透明度的政策环境和市场环境。有助于鼓励高科技民营企业进入电路设计业领域,鼓励生产企业走规模化和面向国内市场自主开发的路子,形成产业群体。 1许居衍院士,2000年。

中国互联网发展史

中国互联网发展史 中国互联网的产生虽然比较晚,但是经过几十年的发展,依托于中国民经济和政府体制改革的成果,已经显露出巨大的发展潜力。中国已经成为国际互联网的一部分,并且将会成为最大的互联网用户群体。 纵观我国互联网发展的历程,我们可以将其划分为以下4个阶段: 一、从1987年9月20日钱天白教授发出第一封E-mail开始,到1994年4月20日NCFG正式连入Internet这段时间里,中国的互联网在艰苦地孕育着。它的每一步前进都留下了深深的脚印。 二、从1994-1997年11月中国互联网信息中心发布第一次《中国Internet发展状况统计报告》,互联网已经开始从少数科学家手中的科研工具,走向广大群众。人们通过各种媒体开始了解到互联网的神奇之处:通过谦价的方式方便地获取自己所需要的信息。 三、 1998-1999年中国网民开始成几何级数增长,上网从前卫变成了一种真正的需求。一场互联网的革命就这么在两年的时间里传遍了整个中华大地。对于IT业来说,这是个追梦的年代这个时候到处都充斥着美梦成真的故事。 四、对于进入2000年的中国IT业来说,梦想已不再那么浪漫了,尽管跨入新千年的天仍然是互联网的天,但这片天空中已飘起了阵阵冷雨,让为网而狂的人们分明感到了几许凉意…… "第一"的年代 正如从0开始后必然是1一样,中国网络时代自1994年从零开始以后,就不停地产生着"第一",因为这是一个创新的年代。让我们通过这些第一记住这个时代。 1、中科院高能物理研究所的IHEPNET与互联网络的连通,迈出了中国和世界各地数百万台电脑的共享信息和软硬件的第一步。边疆也因此而成为我国第一家进入Internet的单位。 2、中国的第一批互联网使用者是全国一千多名科学家。 3、高能所提供了中国第一套万维网服务器。

因特网的发展历程

因特网的发展历程 Internet的发展大致经历了如下四个阶段: 60年代,Internet起源 70年代,TCP/IP协议出现,Internet随之发展起来 80年代,NSFnet出现,并成为当今Internet的基础 90年代,Internet进入高速发展时期,并开始向全世界普及 1、Internet的起源 从某种意义上,Internet可以说是美苏冷战的产物。这样一个庞大的网络,它的由来,可以追溯到1962年。当时,美国国防部为了保证美国本土防卫力量和海外防御武装在受到前苏联第一次核打击以后仍然具有一定的生存和反击能力,认为有必要设计出一种分散的指挥系统:它由一个个分散的指挥点组成,当部分指挥点被摧毁后,其它点仍能正常工作,并且这些点之间,能够绕过那些已被摧毁的指挥点而继续保持联系。为了对这一构思进行验证,1969年,美国国防部国防高级研究计划署(DoD/DARPA)资助建立了一个名为ARPANET (即“阿帕网”)的网络,这个网络把位于洛杉矶的加利福尼亚大学、位于圣芭芭拉的加利福尼亚大学、斯坦福大学,以及位于盐湖城的犹它州州立大学的计算机主机联接起来,位于各个结点的大型计算机采用分组交换技术,通过专门的通信交换机(IMP)和专门的通信线路相互连接。这个阿帕网就是Internet最早的雏形。 到1972年时,ARPANET网上的网点数已经达到40个,这40个网点彼此之间可以发送小文本文件(当时称这种文件为电子邮件,也就是我们现在的E- mail)和利用文件传输协议发送大文本文件,包括数据文件(即现在Internet中的FTP),同时也发现了通过把一台电脑模拟成另一台远程电脑的一个终端而使用远程电脑上的资源的方法,这种方法被称为Telnet。由此可看到,E-mail,FTP和Telnet是Internet上较早出现的重要工具,特别是E-mail 仍然是目前Internet上最主要的应用。 2、TCP/IP协议的产生 1972年,全世界电脑业和通讯业的专家学者在美国华盛顿举行了第一届国际计算机通信会议,就在不同的计算机网络之间进行通信达成协议,会议决定成立Internet工作组,负责建立一种能保证计算机之间进行通信的标准规范(即“通信协议”);1973年,美国国防部也开始研究如何实现各种不同网络之间的互联问题。 至1974年,IP(Internet协议)和TCP(传输控制协议)问世,合称TCP/IP协议。这两个协议定义了一种在电脑网络间传送报文(文件或命令)的方法。随后,美国国防部决定向全世界无条件地免费提供TCP/IP,即向全世界公布解决电脑网络之间通信的核心技术,TCP/IP协议核心技术的公开最终导致了Internet的大发展。 到1980年,世界上既有使用TCP/IP协议的美国军方的ARPA网,也有很多使用其它通信协议的各种网络。为了将这些网络连接起来,美国人温顿·瑟夫(Vinton Cerf)提出一个想法:在每个网络内部各自使用自己的通讯协议,在和其它网络通信时使用TCP/IP协议。这个设想最终导致了Internet的诞生,并确立了TCP/IP协议在网络互联方面不可动摇的地位。

半导体材料的发展进展近况及趋向 引言:随着全球科技的飞速发展成长,半导体材料在科技进展中的首要性毋庸置疑,半导体的发展进展历史很短,但半导体材料彻底改变了我们的生活,从半导体材料的发展历程、半导体材料的特性、半导体材料的种类、半导体材料的制备、半导体材料的发展。从中我们可以感悟到半导体材料的重要性 关键词:半导体、半导体材料。 一、半导体材料的进展历程 20世纪50年代,锗在半导体产业中占主导位置,但锗半导体器件的耐高温和辐射性能机能较差,到20世纪60年代后期逐步被硅材料代替。用硅制作的半导体器件,耐高温和抗辐射机能较好,非常适合制作大功率器件。因而,硅已经成为运用最多的一种半导体材料,现在的集成电路多半是用硅材料制作的。二是化合物半导体,它是由两种或者两种以上的元素化合而成的半导体材料。它的种类不少,主要的有砷化镓(GaAs)、磷化铟(InP)、锑化铟(InSb)、氮化镓(GaN)、碳化硅(SiC)、硫化镉(CdS)等。此中砷化镓是除了硅以外研讨最深切、运用最普遍的半导体材料。氮化镓可以与氮化铟(Eg=1.9eV)、氮化铝(Eg=6.2eV)构成合金InGaN、AlGaN,如许可以调制禁带宽度,进而调理发光管、激光管等的波长。三是非晶半导体。上面介绍的都是拥有晶格构造的半导体材料,在这些材料中原子布列拥有对称性和周期性。但是,一些不拥有长程有序的无定形固体也拥有显著的半导体特征。非晶半导体的种类繁多,大体上也可按晶态物质的归类方式来分类。从现在}研讨的深度来看,很有适用价值的非晶半导体材料首推氢化非晶硅(α-SiH)及其合金材料(α-SiC:H、α-SiN:H),可以用于低本钱太阳能电池和静电光敏感材料。非晶Se(α-Se)、硫系玻璃及氧化物玻璃等非晶半导体在传感器、开关电路及信息存储方面也有普遍的运用远景。四是有机半导体,比方芳香族有机化合物就拥有典范的半导体特征。有机半导体的电导特征研讨可能对于生物体内的基础物理历程研究起着重大推进作用,是半导体研讨的一个热点领域,此中有机发光二极管(OLED)的研讨尤为受到人们的看重。 二、半导体材料的特性 半导体材料是常温下导电性介于导电材料以及绝缘材料之间的一类功效材
