Certainly one of the best spots in the Mediterranean , Barcelona is the capital city of Catalunya and is one of the 17 Autonomous Communities that make up Spain . It is strategically located in a very privileged position on the northeastern coast of the Iberian peninsula, along the Mediterranean coast, around 41 and 2 Its being located at the Mediterranean sea in the very north of the Spanish coast also contributes to making it certainly the most cosmopolitan and most economically active city in the country of Spain . Barcelona is 160 km (100 mi) south of the Pyrenees mountain range and is nestled in between the mouths of the rivers Llobregat and Bes , and the shores of the Mediterranean . It has an altitude of 4 m above sea level and has the following distances from: Tarragona (98 km), Girona (100 km), Lleida (156 km), Huesca (274 km), Castellon (284 km), Zaragoza (296 km) and Madrid (621 km).Located in the comarca of Barcelon , Barcelona is also the second largest city in Spain in both size and population. The city has a population of 1,510,000, but this number escalates to more than 4,000,000 if the outlying areas are also included in the count. As estimated as of year 2005, the population of the city proper is at 1,593,075, while the population of the metropolitan area is at 4,686,701.

简单说下思路：首先计算静力学问题，即先求出假定自由端作用了G=500N时结构在自由端的挠度，这是一个一次超静定问题，你可以按照力法设柱轴力为参数在按照变形协调方程求解，求出轴力后就可以求出C点的静位移yst（即挠度）；然后根据这个静位移yst可以得到冲击动荷系数[1+（1+2h/yst)^0.5]，把G按冲击动荷系数放大后再作用到C点，再次按照力法求解超静定结构的内力，找出最大应力，即可校核梁和柱的强度（因为柱承受轴压，而许用应力相对拉应力而言，因此这里主要需要校核的是梁的强度）。是否可以解决您的问题？

伺服电缸用伺服电机 同步带 滚珠丝杠传动 有较高的重复定位精度 这玩意儿机械部分相对还是比较简单的 电控部分较复杂 尤其多缸控制的多自由度结构。电动缸的结构是电机丝杆结构，有些里面采用同步带驱动丝杆，有些采用齿轮驱动丝杆，电机有无刷电机等多种类型，电机可配置，当采用直流无刷电机或其它伺服电机+编码器的驱动方式时，可以闭 环精确控制电动缸的伸出长度；也有一些采用普通的电机驱动，但在电缸的两端设计了限位开关，用于控制行程的终点，这种电缸的功能类似于气缸。电缸通过传感器、电路等可以对反馈力、运动距离、速度、加速度等进行控制，具体的功能要看具体厂家提供的配置。

分类: 电脑/网络 >> 操作系统/系统故障 解析: 大部分初学者都是在有XP之后装Linux的，下面以我的分区作例子来说明，我的分区情况是： 主分区 C NTFS /dev/hda1 4 GB 扩展分区 /dev/hda2 D NTFS /dev/hda5 10 GBE NTFS /dev/hda6 30 GB F FAT32 /dev/hda7 3 GB /boot ext3 /dev/hda8 40 MB / ext3 /dev/hda9 8.5GB /home ext3 /dev/hda10 1 GB /swap swap /dev/hda11 256MB（和你内存一样或1倍到2倍之间，我的内存就是256MB） (注：后面四个分区都是属于扩展分区，用来装Linux) 1、将下载下来的ISO文件放在格式为FAT32分区的根目录下(如F:)，名称保持一致.(如：shrike-i386-disc1.iso shrike-i386-disc2.iso shrike-i386-disc3.iso)； 2、用UltraISO之类的工具将disc1中的dosutils目录提取出来，放在同一个根目录下(如路径为F:dosutils)； 3、重启机器，设置BIOS从软盘启动后插入MS-DOS盘，或其它可引导盘； 4、进入dosutils目录，运行其中的autoboot.bat文件（输入autoboot即可）； 5、这时出现的是安装界面的语言；选什么随便你，看得懂就好，呵呵； 6、接下来叫你选择键盘类型，你的是什么就选什么，一般默认就好； 7、然后出现的界面是选择安装方法，当然是选择:硬盘驱动器； 8、然后选择分区（这每个人的分区不同，所以不一定相同），就举我的例子，我是把那三个镜像文件和dosutils放在F盘的根目录下，所以选择/输入：/dev/hda7即可； 9、之后安装就开始初始化了，在这一步，一般可以正确识别显示器、显卡和鼠标。之后就开始以文本模式开始安装（只能以文本模式安装）； 10、接下来出现的提示是选择鼠标类型，根据自己的鼠标选择吧，很简单的（为什么有些人装完后鼠标不能识别，我真觉得很神奇:O）； 11、然后选择安装类型，选择：定制 12、之后就进入磁盘分区设置了。第一次安装可以选择让Linux自动分区，安全、省事。我选择：DiskDruid,因为想看看它长什么样，呵呵； 13、进入DiskDruid之后，屏幕上就显示了你目前的分区状况，你可以对它们进行编辑。以我的分区状况为例，在这里，我要为/boot、/、/home分别设置挂载点：/boot、/、/home。注意两个问题，1，挂载点要小写，不然单独的/boot和/home分区会被挂载/BOOT、/HOME文件夹中，达不到预期效果（至于为什么要设单独分区，请参阅相关主题）；2，在编辑“/”的挂载点时，也许会出现警告框，请大胆地选择“强行添加”，没有问题的。最后编辑SWAP分区，确定后选择格式化SWAP区就行； 14、引导装载程序配置，我选择：GRUB（推荐新手使用，因为很简单）之后的两个引导装载程序配置全部跳过，不进行修改； 15、之后到了引导分区设置，在这里可以设置“引导标签”，即在机器启动时，出现在GRUB中选项的名称（WINDOWS操作系统在GRUB中默认显示为DOS，你可以在这里把“DOS”改成“WINXP”等字样）； 16、选择安装引导程序的位置：选择MBR； 17、etho的网络配置：大体分为使用DHCP和不使用DHCP（这是我个人理解方式，呵呵）因为我不是使用DHCP的，所以按空格键把“使用bootp/dhcp”前面的“*”号去掉，选择“引导时激活”，然后输入IP地址、子网掩码、默认网关以及主、次DNS（和XP中的数值一样）； 18、之后可以设置主机名，随便你设 19、是防火墙规则，个人认为没有必要设高。我是选择：定制，然后在WWW（HTTP），邮件（SMTP）和FTP处安空格打上“* ”就好（这样设置之后，浏览网页就没有问题）； 20、语言支持，这是多选项哦，按选多少选多少，但是别忘了中文和英文哦； 21、默认语言，我建议选：USA（就算不懂E文也好），因为默认为英文的话，在Shell下不会出现乱码，看着舒服，安装后又可以改默认语言，怕啥呢; 22、时区，上海，北京，，，，，选吧随便； 23、设置根口令，看你喜欢； 24、验证配置：请在“使用屏蔽口令”和“启用MD5口令”前加上“*”（选中它们）； 25、选择软件包：翻到最后一行，看到：Everything 没有？选吧，等啥，只要选上这个，以后的初级问题基本上不会出现哦。如果空间不足，请务必尽量选上所有开发工具及相关内容，可以避免安装后编译软件出现问题； 26、开始安装..........享受不用换盘的Linux安装吧 PS:在安装的过程中，可以按ALT+FX（FX是指F2、F3、、、F6），有东西看哦，是安装的摘要，如果有出现WARNING之类的词，把它记下来，也许会有用哦。按F1可以回到安装界面。 就这样，如果安装所有软件包，大约1小时后，你就可以“享受”Linux了。（知道“”的意思吗？嘿嘿） 我这样安装之后没有任何系统问题哦！ 1、画面偏移： 大部分人安装完后出现的第一个问题就是画面偏移的问题。当然，这可以通过显示器上的按钮来调 整，可是如果是和XP双系统的话，那每次都调可就麻烦了。解决办法很简单，下个显卡驱动，在X 桌面的虚拟终端键入“init 3”来关闭X桌面，到终端下安装就OK了。如果是NVIDIA的显卡，在安 装后，用VI之类的编辑器编辑/etc/X11/XF86Config文件，把该文件中Driver “nv”中的nv改 成nvidia即可，然后运行startx 启动X系统，画面就正常了。 2、mount分区，可以显示中文文件名的： mount -t vfat -o codepage=936,iocharset=cp936 /dev/hda7 /mnt/win (其中的vfat、hda7、win根据每个人的系统可以改变。936和cp936有的是用gb2312,不过在我 的系统中就不行) 想要让分区在系统启动时自动挂载，则要用vi 等编辑器编辑/etc/fstab,在该文件的末尾加入： 例如：/dev/hda7 /mnt/win vfat auto,codepage=936,iocharset=cp936 0 0 类似的语段 即可。 3、中文字体初步美化： 凡是刚接触Redhat系列的新手打开Mozilla的第一个反应一般都是字体模糊的让眼睛想流泪，其实 解决方法也不难，以下是本人的经验，希望对大家有帮助： 首先在你的Linux中要有simsun.ttf这个字体文件（可以在WINDOWS中找到，也许找到的是 simsun.ttc,直接把它改成simsun.ttf就行。把它弄到Linux中有两个方法，一个是mount,还有一 个是在你用ln -s 建立连接，用后面一个方法可以节省空间，前提是放字体的那个分区在Linux启动 时要自动挂载）;之后在/usr/share/fonts/default目录下建立一个文件夹，名为：myttf,然后将 simsun.ttf文件用cp拷贝到/usr/share/fonts/default/myttf下，这样就可以用ttmkfdir > fonts.dir来生成字体列表。如果要保证列表的完整性，则需要 将/usr/X11R6/lib/X11/fonts/encodings/下的encodings.dir这个文件拷贝 到/usr/share/fonts/default/myttf之后再执行ttmkdir > fonts.dir命令。这时就已经把 simsun字体装入系统了。然后要做的是用vi 打开/etc/X11/XF86Config,在其中的 Section "Files"部分加入：FontPath "/usr/share/fonts/defaults/myttf"这句话，最好放在 原先那个FontPath语句的前面。然后在Section "Module"部分加入 Load "xtt"和 Load "GLcore"，并且在 Load "freetype"和Load "type1"前面加上"#"用以屏蔽它们，因为 它们不能和"xtt"共存。接下来要改的是/etc/gtk/中的gtkrc.zh_CN这个文件，把里面的fontset 部分的后半部，即""后面的内容改为"-misc-simsun-medium-r-normal--16-*-*-*-*-*- gb2312.1980-0,*-r-*",最后打开/etc/gnome/中的gtkrc.zh_CN里的所有Fontset部分全部改 为"-misc-simsun-medium-r-normal--14-*-*-*-*-*-gb2312.1980-0"，这是在GNOME中 的改法。如果是KDE，则在KDE的K菜单―选项―个人化―国家和语言选择中国、字库 zh_CN.gb2312。在K菜单―选项―观感―字体项中选则你想要的字体就可以了（我没用过）。最 后注销重启GNOME就搞定了。 有两点需要注意： LINUX的分区一般用EXT3，在安装过程中，安装程序会要求你选择安装的目标路径（就是目标盘了）此时有两个知识点就是分区格式，选择EXT3，还有一个叫：SWAP，SWAP我也不懂什么，我理解为：相当于虚拟内存，用来加载一些系统的东东，假设你要安装到F盘上，F盘空间为10G=20480MB，没错吧：） 那么你在分区时就要根据你的内存大小，假设你的内存为256M，那么你就要给这个盘分一个叫SWAP的东东，空间为256*2=512，其实剩下全部给EXT3 另外，在LINUX下对硬盘的分区是这样认识的，他所示显示的方式跟WIN不一样， 如果你有两个硬盘：他会显示为：第一个硬为hda，第二个当然是hdb，如果第一个硬盘有三个分区，那么每个分区则显示为hda1,hda2,hda3，假设第二个硬盘也有两个分区，则显示为hdb1,hdb2，吼吼吼

可以。首先计算静力学问题,即先求出静力条件下结构中简支梁中点的静位移yst（即挠度）,它等于简支梁中点作用Q的挠度与悬臂梁端点作用Q/2的端点挠度之和yst=Ql^2/48EI+Ql^2/6EI=3Ql^2/16EI.然后根据这个静位移yst可以得到冲击动荷系数[1+（1+2h/yst)^0.5],得到结构中最大动弯矩为[1+（1+2h/yst)^0.5]×Q/2,结构中悬臂梁固定端和简支梁中点同时达到这个最大值

工作原理：　三相异步电机是感应电机，定子通入电流以后，部分磁通穿过短路环，并在其中产生感应电流。短路环中的电流阻碍磁通的变化，致使有短路环部分和没有短路环部分产生的磁通有了相位差，从而形成旋转磁场。通电启动后，转子绕组因与磁场间存在着相对运动而感生电动势和电流，即旋转磁场与转子存在相对转速，并与磁场相互作用产生电磁转矩，使转子转起来。步骤：　(1)当三相异步电机接入三相交流电源(各相差120度电角度)时，三相定子绕组流过三相对称电流产生的三相磁动势（定子旋转磁动势）并产生旋转磁场，该磁场以同步转速n0沿定子和转子内圆空间作顺时针方向旋转。　　(2)该旋转磁场与转子导体有相对切割运动,根据电磁感应原理,转子导体(转子绕组是闭合通路)产生感应电动势并产生感应电流（感应电动势的方向用右手定则判定）。　　(3)根据电磁力定律，在感应电动势的作用下，转子导体中将产生与感应电动势方向基本一致的感生电流。载流的转子导体在定子产生的磁场磁场中受到电磁力作用(力的方向用左手定则判定)，电磁力对电机转子轴形成电磁转矩，驱动电机转子沿着旋转磁场方向旋转，当电动机轴上带机械负载时，便向外输出机械能。由于没有短路环部分的磁通比有短路环部分的磁通领先，电机转动方向与旋转磁场方向相同。　　详细参考百度百科

钢瓶不可以储存液氢。氢分子很小，压强达到一定程度，H2会透过钢瓶的金属原子空隙渗出来，无法储存。现在一般用储氢合金，生成金属氢化物，使用时加热逸出H2，还有就是新开发的碳纳米管用来储氢。

原理是对的， 你想说什么事 。
