China is the worlds largest coal production and consumption Country,and is also one of the few countries which regard coal as the main sources of energy ,the coal energy rates was very high among energy consumption structure rates in our country.Among them, most of the coal combustion for power generation and heating industry.For large coal-fired power station and boiler,Pulverized coal combustion is the main way of combustion.However, Its one of the most important factors which has restricted the sustainable development that the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning of our country one of the most important factors. Based on the coal combustion efficiency and low pollution comprehensive consideration, corona charged pulverized coal combustion mechanism and experiment research is put forward.By means of high voltage electrostatic field on the solid particles and gas can produce electric charge effect,On one hand, the gas atoms or ions moving kinetic energy is very high,and when contact with the pulverized coal particles,itll transferred part of energy to the coal particle surface, and lead to Particles in an unstable high-energy state , increased the particle surface activity; On the other hand, oxygen, carbon monoxide, corona methane gas ion, electron, has high energy, those make accelerate coal particle combustion reaction rate, reduce combustion reaction temperature become possible. However, in the actual production process of coal, coal is usually in a flow state. From theoretic analysis, the flow of pulverized coal combustion efficiency of pulverized coal is greater than under the static state, Therefore,the pulverized coal flow in charge of combustion enhancement is possible. In this paper,on the basis of pulverized coal particles are charged successfully, through using of the original cyclone electrostatic charge system to build the pulverized coal flow injection charge combustion system. using a photographic record and analysis of its ignition and combustion state, using sampling thermal analysis method of burnout to exploring Charged pulverized coal flow combustion status. Key words: corona discharge, the pulverized coal flow, combustion, thermal analysis 翻译了一会,还挺累,不说百分百准确,基本没什么大的语法错误,望采纳。

IDE是表示硬盘的传输接口。我们常说的IDE接口,也叫ATA (Advanced Technology Attachment)接口。IDE就是将SATA盘映射模拟成普通IDE硬盘,不支持任何SATA接口带来的新技术。IDE模式的兼容性特别的好。IDE就是ATA模式,是并口传输模式,04年前普及的技术,理论最大133Mb每秒。 AHCI(SerialATAAdvancedHostControllerInterface)串行ATA高级主控接口高级主机控制器接口),是在Intel的指导下,由多家公司联合研发的接口标准,它允许存储驱动程序启用高级串行ATA功能,它是Intel所主导的一项技术,可以发挥SATA硬盘的潜在加速功能,大约可增加30%的硬盘读写速度。 AHCI就是SATA模式,串口传输模式,新技术,传输速度快,理论最大300Mb每秒。 ,在安装系统时,无论是Ghost系统,还是安装集成了SATA驱动的光盘XP系统,都可能会出现安装失败或是安装完成后开机蓝屏的情况,这都是因为无法支持AHCI硬盘模式。所以,在安装系统前,需要在BIOS下调成IDE模式,可以在安装完系统,装好SATA驱动后,把硬盘工作模式调成AHCI,这样硬盘就能发挥高于30%的性能。
硬盘IDE和AHCI模式的区别
IDE即Integrated Drive Electronics,它的本意是指把控制器与盘体集成在一起的硬盘驱动器,IDE是表示硬盘的传输接口。常说的IDE接口,也叫ATA(Advanced Technology Attachment)接口,现在PC机使用的硬盘大多数都是IDE兼容的,只需用一根电缆将它们与主板或接口卡连起来就可以了。 AHCI(Serial ATA Advanced Host Controller Interface)串行ATA高级主控接口高级主机控制器接口),是在Intel的指导下,由多家公司联合研发的接口标准,它允许存储驱动程序启用高级串行 ATA 功能,如本机命令队列和热插拔。 扩展资料 两者区别 1、IDE模式接口速度慢,AHCI模式接口速度快。(只是接口速度,内部速度一样。性能影响不大) 2、IDE模式CPU占用高,AHCI模式CPU占用低。 3、IDE模式不支持热插拔,AHCI模式在开启成AHCI以后支持热插拔。 4、IDE模式一个通道支持2块硬盘主板有俩通道,AHCI模式一个通道支持一块硬盘现在主板一般有6~8个以上通道。 参考资料来源百度百科—IDE 参考资料来源百度百科—AHCI
Bios 硬盘模式: IDE 模式和 AHCI 模式是什么意思啊?
开启AHCI之后可以发挥SATA硬盘的潜在的性能,理论上大约可增加30%的硬盘读写速度。 硬盘在BIOS中默认为原生IDE模式,以获得最好的兼容性。如果在此模式下安装了Windows7,再在BIOS中更改硬盘为AHCI模式,就无法进入系统,需要重新安装系统才行。不用重装系统,就打开硬盘的AHCI模式方法 STEP1在点击开机菜单后,选择菜单中的“运行”栏目。在运行栏目的输入框内键入“regedit”,回车即可打开注册表编辑器。 STEP2打开注册表编辑器之后,进入“HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci”键值。在右边窗口中双击名称为“Start”的项目,会弹出一个对话框,将默认的参数由3更改为0。点击“确定”并且保存之后,重新启动电脑。 STEP3重启电脑之后,进入BIOS,在“Integrated Peripherals”页面中,将“SATA RAIDAHCI Mode”更改为“AHCI”(不同BIOS选项名称会有细微差别)。 保存重启,进入系统后系统会自动安装AHCI的驱动程序。
硬盘开启AHCI有什么用啊?
可以提升性能。 AHCI是串行ATA高级主控接口的英文缩写,它是Intel所主导的一项技术,它允许存储驱动程序启用高级SATA功能,如本机命令队列(NCQ)和热插拔。开启AHCI之后可以发挥SATA硬盘的潜在的性能,理论上大约可增加30%的硬盘读写速度。 硬盘在更改为AHCI模式之后,系统启动的速度变化不大。不过在进行大文件拷贝时,速度由原来的60MBS提升到了71MBS,性能提升约20%。硬盘在Windwos7中的系统评分中,也由开始的5.9分提升到了6.5分。由此可见硬盘开启AHCI之后,效果是不错的。
好了,本文到此结束,希望对大家有所帮助。
