Second, strengthening the construction of clean and honest Government and fight against corruption. Seriously implement the honest responsibility, actively carry out the independent Commission against corruption interview system, increase the leadership and the day-to-day supervision of party members and cadres at all levels, strengthen the not Winds of special treatment, treatment of "laid-back luxury and arrogance" and "three-pronged" problem, non-gang, national public officers, serving in leadership positions is not land, above-standard equipped with buses and cars for private purposes, and recreational city of gifts, hospitality, luxury and waste, "emptied the rating" special rectification work. Adhere to the rot will be punishing, corrupt Su, and 1 village, 4 disciplinary administrative cadres and workers. Three is to strengthen peace to create a work. Strengthen source management, adhere to prevention, focusing on prevention. Carry out the "big reception, big tour" campaign, petitioning for the cadres of the 主流视频线类别 视频线顾名思意是用来传输视频信号的，它用来连接 媒体播放设备及显示设备， 媒体播放设备有 DVD机，HTPC，(VCD机，录像机就不提了吧)，视频线有以下几种: AV线: 这是最老的传输模拟视频信号的视频线，两端是莲花头(RCA头), 目前DVD机及电视机都会有这种接口，装修时不需要布这种线; S端子线: 前几年出现的比AV线质量好一点的视频线，接口是圆形的，类似PS2鼠标头，这种线也落后了，不建议布; 三色差线: 比S端子线线质量更好的视频线， 传输模拟信号，目前应该是模拟信号中最好的视频线，新近出的DVD机，高端电视，以及家用投影机都会带有这种接口。如果你的播放设备和显示设备比较远的话，装修时要考虑布色差线了。 VGA线: 也是一种模拟信号视频线，最常见于电脑，其信号与色差线相比各有千秋，但随着视频数据量的加大， 例如未来要传输1920X1080P的视频信号，那么色差线的冗余会更大，分辨率超过1600X1200后，VGA线质量稍次，长度稍长会导致雪花。家庭影院为什么要提到VGA线呢,那是因为HTPC走入家庭影院，所有投影机都带有VGA接口，VGA线也是布线时必须考虑的线种。 DVI线: 全称Digital Visual Interface, 最新的数字视频线， 以无压缩技术传送全数码信号，最高传输速度是8Gbps，目前已获多数厂家支持的数字视频信号线，接口的传输速度高达8Gbps，其接口有24+1(DVI,D), 24+5(DVI,I)型，DVI,I支持同时传输数字(DVI-D)及模拟信号(VGA信号),一般来说HTPC的显卡一般是DVI-I接口， 而液晶显示器，投影机上是DVI-D接口. DVI-I的接口虽然兼容DVI-D的接口，但DVI-I的插头却插不了DVI-D的接口，为什么呢,多了四根针。 但我们还是有办法的， 使用一个DVI-I转DVI-D的转换器。 HDMI线:全称Hi-Definition Multimedia Interface, 比DVI更新的数字视频线， 以无压缩技术传送全数码信号，最高传输速度是3.95Gbps，HDMI除了传输视频外，还支持八声道96kHz或单声道的192kHz数码音频传送，但目前支持HDMI的设备还不是太多. 其接口可与DVI接口转换(视频信号部分). 综上所述，在装修阶段要想支持目前所有的显示设备: 普通电视，等离子，液晶电视，背投，LCD影院投影机，DLP影院投影机，我们应该布哪些线呢, 如果希望兼容所有的器材，最好布三种线，最常见的VGA线(所有设备最起码的支持)，模拟信号的色差线，数字信号的DVI线， HDMI接口目前较少，如果万一有此类设备，也可以在DVI线上通过DVI-HDMI转接口连接。 for more than 60 years of rural senior party member care funds; System of regulating the activities of grass-roots party organizations, and enhance the sense of belonging of grass-roots party members; Hold fast to implement "red credit", "red stake" two major project opportunities, strive to explore new ways of development of village collective economy, rural collective economy achieve breakthrough; A progress review by the Secretary of the party work of grass-roots party organizations, strengthens the responsibility of grasping party building, Party Secretary.

Carry out the "big reception, big tour" campaign, petitioning for the cadres of the 主流音频线类别 音频线是用来连接音源设备和功率放大器的。 市场上品质较好的音响线，其制作材料主要有镀金、银、元氧铜，非金属碳量较高的以进口线为多，但其价格较为昂贵，一般的都需几百元一根，主要有美国的MONSTER STANDRDINTERLINK(怪兽)、AUDIO0UEST(线圣)、SUPRA(鳖鱼)、M0NITERPC(魔力)、SPACE&TIME(超时空)、MISSION(美声)、PATRDNICS(柏力)、VDH(荷兰-范登豪)等等。 对于一般普及型(万元以下)的音响器材无需刻意追求线材的高品质，只要使用一般截面较大一点的铜芯信号线即可。对于较好的家庭影院音响器材，可以考虑使用高品质的音响线，比如在DVD视盘机和“AC-3”解码器上都有光纤输出、输入接口，如采用光纤传输线，它对音色的改善能得到较明显的作用。 音频线: 一套音频线经常是两根，分为左右两个声道，线的两端都是莲花头(RCA头)。 同轴线: 用于传输多声道信号(杜比AC-3或者DTS信号)，与音频线类似，因信号量大，接头及线都比普通音频线粗一些，一般用于连接DVD机与功放机。 光纤线: 也用于传输多声道信号(杜比AC-3或者DTS信号)，用于连接DVD机与功放机。 话筒线: 一种两芯的同轴线，用于连接功放与话筒。目前无线话筒兴起，如果不是出于特别考虑，布线时可以不予考虑，以后无线话筒应用肯定会越来越广。 音频线在布线时基本无需考虑，因为音源设备与功放经常放在一起，这些线都很短，后期配置即可。 二 家庭影院布线 在家庭影院布线(一)中说到只有视频线，音箱线装修时需要考虑，音频线(因为音源设备与功放可以放在同一位置，所以音频线很短)不需要考虑。下面讨论一下视频线与音箱线的布线。 视频线布线 如果你仅用电视或者等离子，液晶电视作为显示设备，视频线也不是太需要考虑。但家用投影机具有大画面，临场感强等其他显示设备说不具有的优势，未来肯定有大发展，我们装修不能仅仅为眼前考虑，装修一次至少也要保十年用途吧，十年之内估计也就两三年内家用投影机肯定进入很多家庭。 视频线一端连接DVD播放机或者HTPC, 另一端连接投影机。 DVD机的位置for more than 60 years of rural senior party member care funds; System of regulating the activities of grass-roots party organizations, and enhance the sense of belonging of grass-roots party members; Hold fast to implement "red credit", "red stake" two major project opportunities, strive to explore new ways of development of village collective economy, rural collective economy achieve breakthrough; A progress review by the Secretary of the party work of grass-roots party organizations, strengthens the responsibility of grasping party building, Party Secretary.

Carry out the "big reception, big tour" campaign, petitioning for the cadres of the 一般是固定的，一般在视听室前部正中间，投影机位置有三处: 1 将投影机吊在视听室后部天花板上， 使用专有的投影机吊架，其位置上下可调，较灵活; 2 如果视听室后墙正好有一排柜子，投影机可考虑放在柜子中或柜子上; 3 投影机放在投影车上，投影车可移动，放置在人的位置前面。 无论是哪一种，都建议将视频线从地面或者天花从前部中央处连接到后部合适位置，因为视频线的两种: 色差线和DVI线都很粗，暴露在外面是很难看的。 色差线和DVI线由于太粗，皆不能穿管，只能用线槽，地面铺墙砖时要考虑其高度。 色差线和DVI线均没有相应插口，在墙上打上线盒后，多留出一米的长度用于直接连接DVD机或者投影机即可。 没有合适面板可以使用白板，让装修工人在上面打个洞即可。色差线与DVI线质量均很关键，此类线材因加载信号量大，对线材质量很高，一般也都较贵。 音箱线布线要点 音箱线可以布成5.1声道方式，如果视听室够大，以后想上比较专业的设备，也可以布成7.1声道方式，不过5.1声道环绕声效果已经很不错了，其实不用在这种效果上过多追求，更重要的还是音质与画质。 5(1声道与7.1声道的音箱摆位 音箱线一端连接功放机，一端连接音箱，5.1声道的连线如下图所示，低音箱因低音无方向性，一般放置在功放旁边，低音箱线也就不用布了。 for more than 60 years of rural senior party member care funds; System of regulating the activities of grass-roots party organizations, and enhance the sense of belonging of grass-roots party members; Hold fast to implement "red credit", "red stake" two major project opportunities, strive to explore new ways of development of village collective economy, rural collective economy achieve breakthrough; A progress review by the Secretary of the party work of grass-roots party organizations, strengthens the responsibility of grasping party building, Party Secretary.
