储氢合金能吸收烃类吗

一种新型合金,一定条件下能吸收氢气,一定条件能放出氢气:循环寿命性能优异,并可被用于大型电池,尤其是电动车辆、混合动力电动车辆、高功率应用等等。中文名储氢合金外文名hydrogen storage metal日期20世纪60年代作用能储存氢的金属和合金发展简介分类主要用途TA说发展20世纪60年代,材料王国里出现了能储存氢的金属和合金,统称为储氢合金(hydrogen storage metal),这些金属或合金具有很强的捕捉氢的能力,它可以在一定的温度和压力条件下,氢分子在合金(或金属)中先分解成单个的原子,而这些氢原子便“见缝插针”般地进入合金原子之间的缝隙中,并与合金进行化学反应生成金属氢化物(metal hydrides),外在表现为大量“吸收”氢气,同时放出大量热量。而当对这些金属氢化物进行加热时,它们又会发生分解反应,氢原子又能结合成氢分子释放出来,而且伴随有明显的吸热效应。20世纪70年代,LaNi5和Mg2Ni在荷兰Philips与美国Brookhaven实验室相继被发现具有可逆的吸放氢能力并伴随的一系列物理化学机理变化。1973年起,LaNi5开始被试图作为二次电池负极材料采用,但由于其循环性能较差,未能成功。1984年,荷兰Philips公司成功解决了LaNi5合金在循环中的容量衰减问题,为MH/Ni电池发展扫清了最后一个障碍。储氢合金粉末简介别看储氢合金的金属原子之间缝隙不大,但储氢本领却比氢气瓶的本领可大多了,因为它能像海绵吸水一样把钢瓶内的氢气全部吸尽。具体来说,相当于储氢钢瓶重量1/3的储氢合金,其体积不到钢瓶体积的1/10,但储氢量却是相同温度和压力条件下气态氢的1000倍,由此可见,储氢合金不愧是一种极其简便易行的理想储氢方法。采用储氢合金来储氢,不仅具有储氢量大、能耗低,工作压力低、使用方便的特点,而且可免去庞大的钢制容器,从而使存储和运输方便而且安全。分类目前储氢合金主要包括有钛系、锆系、铁系及稀土系储氢合金。主要用途氢气分离、回收和净化材料。化学工业、石油精制以及冶金工业生产中,通常有大量的含氢尾气排出,含氢量有些达到50~60%,而目前多是采用排空或者白白的燃烧处理。因此,对这部分加以回收利用,在经济上有巨大的意义。另外,集成电路、半导体器件、电子材料和光纤等产业中,需要超高纯氢体。利用储氢合金对氢原子有特殊的亲和力,而对其他气体杂质择优排斥的特性,即利用储氢合金具有只选择吸收氢和捕获不纯杂质的功能,不但可以回收废气中的氢,而且可以使氢纯度高于 99.9999%以上,价格便宜、安全,具有十分重要的社会效益和经济意义。制冷或采暖设备材料。由于储氢合金具有在吸氢化学反应时放出大量热,而在放氢时吸收大量热的特性,因此,人们可以利用储氢合金的这种放热——吸热循环,可进行热的储存和传输,制造制冷或采暖设备。美国和日本竞相采用储氢合金制成太阳能和废热利用的冷暖房,其原理就是利用储氢合金在吸氢时的放热反应和释放氢时的吸热反应。我国北京有色金属研究总院则利用储氢合金储放氢过程的吸放热循环效应,制造了一台可以制冷到77K的制冷机,该机器可用于工业、医疗等行业需要低温环境的场合。镍氢充电电池。由于目前大量使用的镍镉电池(Ni-Cd)中的镉有毒,使废电池处理复杂,环境受到污染,因此它将逐渐被用储氢合金做成的镍氢充电电池(Ni-MH)所替代。从电池电量来讲,相同大小的镍氢充电电池电量比镍镉电池高约1.5~2倍,且无镉的污染,现已经广泛地用于移动通讯、笔记本计算机等各种小型便携式的电子设备。目前,更大容量的镍氢电池已经开始用于汽油/电动混合动力汽车上,利用镍氢电池可快速充放电过程,当汽车高速行驶时,发电机所发的电可储存在车载的镍氢电池中,当车低速行驶时,通常会比高速行驶状态消耗大量的汽油,因此为了节省汽油,此时可以利用车载的镍氢电池驱动电动机来代替内燃机工作,这样既保证了汽车正常行驶,又节省了大量的汽油,因此,混合动力车相对传统意义上的汽车具有更大的市场潜力,世界各国目前都在加紧这方面的研究。其他资料某些金属具有很强的捕捉氢的能力,在一定的温度和压力条件下,这些金属能够大量“吸收”氢气,反应生成金属氢化物,同时放出热量。其后,将这些金属氢化物加热,它们又会分解,将储存在其中的氢释放出来。这些会“吸收”氢气的金属,称为储氢合金。储氢合金的储氢能力很强。单位体积储氢的密度,是相同温度、压力条件下气态氢的1000倍,也即相当于储存了1000个大气压的高压氢气。由于储氢合金都是固体,既不用储存高压氢气所需的大而笨重的钢瓶,又不需存放液态氢那样极低的温度条件,需要储氢时使合金与氢反应生成金属氢化物并放出热量,需要用氢时通过加热或减压使储存于其中的氢释放出来,如同蓄电池的充、放电,因此储氢合金不愧是一种极其简便易行的理想储氢方法。目前研究发展中的储氢合金,主要有钛系储氢合金、锆系储氢合金、铁系储氢合金及稀土系储氢合金。储氢合金不光有储氢的本领,而且还有将储氢过程中的化学能转换成机械能或热能的能量转换功能。储氢合金在吸氢时放热,在放氢时吸热,利用这种放热-吸热循环,可进行热的储存和传输,制造制冷或采暖设备。储氢合金还可以用于提纯和回收氢气,它可将氢气提纯到很高的纯度。例如,采用储氢合金,可以以很低的成本获得纯度高于99.9999%的超纯氢。储氢合金的飞速发展,给氢气的利用开辟了一条广阔的道路。储氢合金,当其用于电池,具有高放电(功率)性能和优异的放电性能,此外,裂化很少,循环寿命性能优异,并可被用于大型电池,尤其是电动车辆、混合动力电动车辆、高功率应用等等。该储氢合金具有伴随着储氢容量(H/M)变化的相变,并且当其储氢容量 (H/M)落入0.3~0.7或0.4~0.6范围内时,该储氢合金处于单一相或接近单一相的状态

如何在debian下快速安装中文字体

具体安装步骤如下:安装必要的软件: 美化自己的桌面环境,首先必须要安装一些软件包,用管理员的身份使用如下命令安装,如果已经安装过的则可以跳过这一步。 # apt-get install x-ttcidfont-conf libft-perl libttf2 defoma libfreetype6 fontconfig libxft2其中,defoma将统一管理xtt、freetype和PS字型,而籍由调用libxft(支持反锯齿)来处理字型的,则是由FontConfig统一管理。而x-ttcidfont-conf软件包是defoma的一个插件,用于管理TrueType和CID字体。 在安装的过程中,系统会提示你将两个目录加入到X Window的配置文件中。如果不做这一步,传统的X Window应用程序将会无法使用defoma管理的TrueType字体。因此,用文本编辑器编辑/etc/X11/XF86Config-4,在其中Files一节中加入:FontPath "/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType"FontPath "/var/ilb/defoma/x-ttcidfont-conf.d/dirs/CID"同时注释掉# FontPath "unix/:7100" # local font server# FontPath "/usr/lib/X11/fonts/CID"在其中Module一节中加入:Load "xtt"同时注释掉# Load "freetype"如果存在文件/etc/X11/fs/config或/etc/X11/fs-xtt/config的话,也同时注释掉其中"catalogue"路径列表中的"/usr/lib/x11/fonts/CID"路径。安装英文字体 虽 然本文重点在于中文桌面的美化,但没有漂亮的英文字体,桌面也是好看不了的。在Linux上可以选择的英文字体非常多,其中我个人比较欣赏的是由 Bitstream出品的Vera系列字体,和由Microsoft提供的Windows核心字体。前者是一款开源字体,而后者则可以从SourceForge下载免费使用。由于很多文档在Windows上编写,使用Windows的核心字体可以获得最好的显示效果。Bitstream的字体可以直接用apt-get命令安装,而MS的核心字体则需要先从SourceForge的Smart package of Microsoft"s core fonts项目下载,或者是在安装的过程中由安装程序下载。使用如下命令可以安装上述字体: # apt-get install ttf-bitstream-vera msttcorefonts在安装后者时需提供已下载字体包的路径或提供可以直接访问SourceForge的网络环境。安装中文字体由于需要安装的中文字体包并非Debian官方发布中的内容,因此,需要修改/etc/apt/sources.list,在其中加入如下内容: deb http://211.100.7.181/~liling/debian/ttfonts/ ./然后执行如下命令: # apt-get update# apt-get install ttf-microsoft-simsun ttf-microsoft-simhei# apt-get install ttf-microsoft-simyou ttf-microsoft-simli这些中文字体包使用的是中文Win98及Office中的TTF字体,为了能配合cjk-latex,在打包时选择了TTF而非TTC字体。这 些字体在X Window的应用程序中可以通过-default-song-*、-default-hei-*、-default-youyuan-*和- default-lisu-*来访问。另外两款常用的中文字型仿宋和楷体,我们就使用文鼎公司提供的版本,它们在Debian中的软件包的名字是ttf-arphic-gbsn00lp和ttf-arphic-gkai00mp,可以用apt-get命令来安装。中文字体安装好后,可以重新启动X Window或者是用xset刷新字体,然后再用xfontsel便可看到新的字体了。同时,使用GNOME或者KDE也可以在字体选择的对话框中看到新的字体了。如果你想手工安装字体而不是使用字体包,最重要的事情就是要为每个字体准备好defoma字体描述文件,defoma就是通过这些描述文件来为每一个需要的应用程序注册字体信息的。上述四个字体的描述文件为simsun.hints、simhei.hints、simli.hints、simyou.hints。注册字体的命令为defoma-hints,这方面的介绍请参见如何在Debian下手工安装中文字体。修改fontconfig配置安装好中文TrueType字体之后,可以通过修改应用程序的配置达到获得漂亮字体的效果,然而,是否有一种可以不需要做任何的修改就得到漂亮字体的方案呢?答案是肯定的,只要修改fontconfig的配置就可以了。fontconfig的配置是XML格式的文件,它的作用就是在应用程序所需要的字体名称和系统安装好的字体之间进行匹配,以及修改字体的缺省配置,如AA(AntiAlias)等。fontconfig 有两个系统配置文件和一个用户配置文件。其中系统配置文件分别是/etc/fonts/fonts.conf和 /etc/fonts/local.conf。前者供发型版的制作者使用,后者供系统管理员使用。后者的优先级比较高,这样一旦为一个系统配置好字体,它 就不会受到发型版提供者所提供的软件包改动的影响,即便升级fontconfig软件包,也不用担心编写好的配置被覆盖。在每个用户的Home目录中,也 可以存放一个.fonts.conf文件,这个文件的优先级最高,但它只影响当前的用户。自己改fontconfig的配置是一件比较麻烦的事情,最方便的就是把别人已经配置好的local.conf拿来,覆盖原先的版本,或者是作为个人的配置文件。在此,给出我正在使用的local.conf文件以供参考。安装好字体配置文件后,再次重启X Window,便可以得到漂亮的字体了。

三相异步电动机的工作原理是什么

三相绕组接通三相电源产生的磁场在空间旋转,称为旋转磁场,转速的大小由电动机极数和电源频率而定。转子在磁场中相对定子有相对运动,切割磁杨,形成感应电动势。转子铜条是短路的,有感应电流产生。转子铜条有电流,在磁场中受到力的作用。转子就会旋转起来。第一:要有旋转磁场,第二:转子转动方向与旋转磁场方向相同,第三:转子转速必须小于同步转速,否则导体不会切割磁场,无感应电流产生,无转矩,电机就要停下来,停下后,速度减慢,由于有转速差,转子又开始转动,所以只要旋转磁场存在,转子总是落后同步转速在转动。

氢能源动力汽车的储氢方法与材料

传统储氢方法有两种,一种方法是利用高压钢瓶(氢气瓶)来储存氢气,但钢瓶储存氢气的容积小,而且还有爆炸的危险;另一种方法是储存液态氢,但液体储存箱非常庞大,需要极好的绝热装置来隔热。近年来,一种新型简便的储氢方法应运而生,即利用储氢合金(金属氢化物)来储存氢气。研究证明,在一定的温度和压力条件下,一些金属能够大量“吸收”氢气,反应生成金属氢化物,同时放出热量。其后,将这些金属氢化物加热,它们又会分解,将储存在其中的氢释放出来。这些会“吸收”氢气的金属,称为储氢合金。其储氢能力很强。单位体积储氢的密度,是相同温度、压力条件下气态氢的1000倍,也即相当于储存了1000个大气压的高压氢气。储氢合金都是固体,需要用氢时通过加热或减压使储存于其中的氢释放出来,因此是一种极其简便易行的理想储氢方法。目前研究发展中的储氢合金,主要有钛系储氢合金、锆系储氢合金、铁系储氢合金及稀土系储氢合金。储氢合金还有将储氢过程中的化学能转换成机械能或热能的能量转换功能。储氢合金在吸氢时放热,在放氢时吸热,利用这种放热-吸热循环,可进行热的储存和传输,制造制冷或采暖设备。此外它还可以用于提纯和回收氢气,它可将氢气提纯到很高的纯度。例如,采用储氢合金,可以以很低的成本获得纯度高于99.9999%的超纯氢。储氢合金的飞速发展,给氢气的利用开辟了一条广阔的道路。目前中国已研制成功了一种氢能汽车,它使用储氢材料90千克,可行驶40千米,时速超过50千米。今后,不但汽车会采用燃料电池,飞机、舰艇、宇宙飞船等运载工具也将使用燃料电池,作为其主要或辅助能源。另外由于大量使用的镍镉电池(Ni-Cd)中的镉有毒,使废电池处理复杂,环境受到污染。镍氢电池与镍镉电池相比,具有容量大、安全无毒和使用寿命长等优点。发展用储氢合金制造的镍氢电池(Ni-MH),也是未来储氢材料应用的另一个重要领域。

@RequestParam与@RequestHeader

SpirngMVC默认如何获取请求带来的各种信息? 直接给方法入参上写一个和请求参数名相同的变量,这个变量就来接受请求参数的值; 例如: 1.当请求是 localhost:8080/handle01?username=yst 时,handle01里的username会自动匹配 yst 。所以输出: 2.当请求是 localhost:8080/handle01?user=yst 时,handle01里的username匹配不到值,因为请求里没有 username 。所以输出: 如果用此注解,参数默认是必须带的。它有如下方法: 形式: 也就是说你直接输入 localhost:8080/handle02? 会报错,不会执行方法 。只能输入 localhost:8080/list?username=? 才能执行相应的方法。 请求是 localhost:8080/handle01?user=yst 时,可以成功输出: 如下 这种情况可以不带参数 这样在地址里面也可以不带参数,如果带了参数会接收,不带参数会默认为“你没带” 使用 @RequestHeader 绑定请求报头的属性值。请求头包含了若干个属性,服务器可据此获知客户端的信息,通过 @RequestHeader 即可将请求头中的属性值绑定到处理方法的入参中 。

雅马哈 yst-sw011好不好

肯定10寸的要好些,低音炮主要取决喇叭口径,口径大了声音才震撼,低频扩散的比较广,011好像是8寸还是6寸的,这个太小了,开大声会失真,只能说下潜度比较好,但是震撼绝对比不上10寸的。希望对你有帮助。

储氢合金与氢气是氧化还原反应吗

是氧化还原反应。储氢合金,就是能储存氢的金属和合金,这些金属或合金具有很强的捕捉氢的能力,它可以在一定条件下,与氢气进行化学反应生成金属氢化物,外在表现为大量“吸收”氢气。对这些金属氢化物进行加热时,它们又会发生分解反应,释放出氢分子。
