Lol, my frend have one guy, who spam his forum. And he write post with link to his site(spammers site). Anchor text is 'bebec'(mean idiot).
And spammer's site is first on our local SE, for keyword 'bebec'. LoL! For Google maybe you need more backlinks, but BACKLINKS ARE VERY IMPORTANT!!! |

Free WoW Power Leveling: Stay Away From Scam SitesIf you've ever done a search for power leveling on Google or Yahoo, you know how expensive these services can cost you. Who wants to pay three or four hundred dollars just so somebody else gets to play the game for you? It seems insane, but people actually fall for these services, many of which turn out to be scams anyway. You should never give away your account information to anybody, and even Blizzard will never ask your for that information. However, leveling up your character as quickly as possible does have a lot of allure. With free WoW power leveling, you can get all the benefits of power leveling without paying a single cent. Don't Pay Somebody Else Where is the logic in paying somebody else to play the game for you? It simply doesn't make any sense, and you're missing out on at least half of what World of WarCraft has to offer you. However, you don't need to take your time if you don't want to. Free WoW Power Leveling lets you quickly progress through 70 levels without breaking a sweat. There are some guides for free online, although you can alternatively choose to pay a small fee (about $30 or so) for some of the more comprehensive guides out there. 100% free WoW power leveling is all about choices though, and you're given a whole bunch to get to level 70 with. First, you can choose between grinding and questing. The latter is probably more entertaining to a lot of folks, but it can present some difficulties at times for casual players. Firstly, some quests require groups to complete, but free WoW power leveling will help you choose the quests which are easy for solo players to complete on their own. Some might reasonably argue that the whole reason of playing an MMO is to play with other folks, but sometimes it's just easier to do things on your own. By being able to complete solo quests, you'll become a stronger player overall because you won't have to rely on others to keep your alive and help you complete objectives. Of course, you could always turn to grinding for your free WoW power leveling needs. Grinding is a little less entertaining because it refers to monotonous killing of monsters over and over to rack up those experience points. Still, you can set the pace at which you want to earn experience with this method, and if one monster is too powerful for you, you can always just move onto another area. Both questing and grinding will help you level up more quickly than you would by figuring things out on your own, and free WoW power leveling means you won't have to pay anything to level up. ------------------------------------------------------------------------------------------------------------------------------

净水器的种类及工作原理 世界上大多数的水体污染严重,加剧了水资源紧缺的矛盾。传统的自来水处理方法,已不能 保证提供品质优良的饮用水,而且在市政供水中还存在着两次污染的问题,如高层的水箱供水,漫长的自来水输送 管线,都会造成潜在的铁锈,水垢及微生物等污染问题,因此,各种品牌的净水器应运而生。 净水器按水质处 理方式,可分为以下11大类。 1.软化法是指将水中硬度(主要指水中钙、镁离子)去除或降低一定程度的水。水在软化过程中,只是软化 水质,而不能改善水质。 2.蒸馏法 是指将水煮沸,然后收集蒸汽,使之冷却和凝结成液体。蒸馏水是极安全的饮用水,但有一些问题要进一步探讨。 由于蒸馏水不含矿物质,这成为反对者提出人的寿命容易老化的理由。另外利用蒸馏法成本较高,耗费能源,不能 去除水中挥发性物质。 3.煮沸法 是指自来水煮沸后饮用,这是一种古老的方法,在国内普遍地应用。水煮沸可杀死细菌,但对一些化学物质和重金 属不能去除,即使其含量极低,所以饮用仍是不安全的。 4.磁化法 是指利用磁场效应处理水,称为水的磁化处理。磁化处理的过程就是水在垂直于磁力线的方向通过磁铁后,即完成 磁化处理的过程。我国对水的磁化处理,到目前为止仍是处于实践和研究的初级阶段,国外的净水器没有磁化功能 的要求,因为磁化水不属于净水的范围,而是属于医疗方面的问题。 5.矿化法 是指在净化的基础上再向水中增添对人体有益的矿物元素(如钙、锌、锶等元素)其目的是发挥矿泉水的保健作用 。市售净水器一般通过在净水器中添加麦饭石来达到矿化的目的,但人为的矿化功效现在还是一个有争议的问题。 6.臭氧、紫外线杀菌 这些方面都只能杀菌,去除不掉水中的重金属和化学物质,经杀死的细菌尸体仍残留在水中,而成为 热原。 7.整水器整水器是日本新发明的产品,它是把水先进行净化处理,然后再进行电解活化,其碱性活化水与人 体内环境之PH值相对应,对人体有保健作用,适于饮用;酸性活化水可用于洗脸、洗澡,有美容作用。不过,对 整水器的整水原理、整水水质以及使用后对人体的影响,均有不同的看法,需进一步探讨。 8.活性碳吸附 可分为以下三种形态 8.1颗粒活性炭 较为常用,多用本质、煤质、果壳(核)等含碳物质通过化学法或物理活化法制成。它有非常多的微孔和比表面积 ,因而具有很强的吸附能力,能有效地吸附水中的有机污染物。此外在活化过程中,活性碳表面的非结晶部位形成 一些含氧官能团,这些基团使活性碳具有化学吸附和催化氧化、还原性能,能有效去除水中一些金属 离子。 8.2渗银活性碳 将活性炭和银结合在一起,不仅对水中有机污染物有吸附作用,还具有杀菌作用,而且在活性炭内不会滋长细菌, 解决了净水器出水有时出现亚硝酸盐含量高的问题。当水通过渗银活性碳时,银离子就会慢慢释放出来,起到消毒 杀菌作用。由于活性炭对除去水中色、嗅、氯、铁、砷、汞,氰化物、酚等具有较好效果,除菌效果90%以上, 因此被应用小型净水器中。 8.3纤维活性炭 有机炭纤维经活化处理后形成的一种新型吸附材料,具有发达的微孔结构,巨大的比表面积,以及众多的官能团。 国外在采用纤维活性炭进行溶剂回收,气体净化等方面已取得了显著的成就;在水处理应用方面也做了大量的研究 工作。 9.RO逆渗透膜 RO逆渗透是一种通过目前国际流行的反渗透等办法,对原水进行过滤处理(物理法)后不添加任何化合物而生产 出可供人类直接饮用的纯净水机器(也称为终端净水设备)。采用水质符合中国卫生部《生活饮用水水质卫生规范 》(2001)规定的市政自来水为原水,通过2个活性炭滤芯(1个颗粒活性炭、1个烧结活性炭)1个PPF 溶喷滤芯对原水进行预过滤,再对预过滤水施加压力令其通过孔径大小为万分之一微米的RO(反渗透,英文Re verse Osmosis)膜,最后通过材质为果壳(椰壳)的载银活性碳(又名小T33)调节水的酸碱度(使制出的纯 净水口感变得甘甜醇美)而生产出纯净水。 RO逆渗透净水机,引进美国先进的超低压逆渗透技术和配件,生产出国内最为先进的家用和团体用纯净水装 置,该装置产水优质、安全运行、稳定可靠、操作简单,占地面积小,最有效的去除水中钙、镁、细菌、有机物、 无机物、金属离子和放射性物质等,经过该装置净化出的水晶莹清澈、甜美甘醇。该装置适用于家庭和宾馆、酒店 、医院等企事业单位饮用净水使用。 RO逆渗透净水机制出的纯净水相对于桶装水更新鲜、更卫生、更安全,它的用途非常广泛:可以生饮,也可 以烧开喝,在这方面最突出的特点是水壶或电暖瓶再也不会结水垢了;纯水用于烹饪,更加卫生,更加可口;用纯 水洗浴,可以清除皮肤上的杂质,滋润皮肤,起到自然美容的效果;可以提供给加湿器、蒸汽熨斗、美容仪等小家 电所需用水,决不会出现让人讨厌的水垢;与制冰机配套使用,制成的冰块晶莹剔透,无任何异味。 逆渗透技 术:逆渗透原文是REVERSE OSMOSIS,它是美国太空总署集合多国科学家, 在政府支持下,花费数十亿美元,经过多年研究而成。 逆渗透的原理是在原水一方施加比自然渗透压力更大的压力,使水分子由浓度高的一方逆渗透到浓度 低的一方 。由于逆渗透膜的孔径远远小于病例毒和细菌的几百倍乃至上千倍以上,故各种病毒,细菌, 重金属,固体可溶物,污染有机物,钙镁离子等根本无法通过逆渗透膜,从而达到水质软化净化的目的。 10 .微过滤及超过滤法 微过滤法是用纤维素或高分子材料制成的微孔滤膜,利用其均一孔径来截留水中的微粒、细菌、胶体等,使其不通 过滤膜而被去除。这种微孔膜过滤技术又称粒密过滤技术,能够过滤微米或纳米级的微粒和细菌。超过滤和微过滤 都属于膜分离技术,两者之间不存在明显的界限,超过滤的工作压力一般以0.3兆帕左右,可去除水中大分子物 质、细菌、病毒等,但通量较低。 11.复合型 当一种工艺难以去除水中有害物质时,采用二种或两种以上的工艺即为复合型。如活性炭吸附?紫外线杀菌、活性 炭吸附?反渗透、活性炭吸附?微过滤(超过滤)、聚丙烯超细纤维?活恬炭?微过滤(超过滤)等。在复合型净 水器中,膜技术复合净水器净水性能优良,特别在去除微生物(细菌、藻类等)方面有比较显著的效果,其中一些 品质优良的净水器出水可以直接生饮,得到了广大消费者的欢迎,已成为净水器当前发展的热点。 从以上净水器的分类方法中不难看出,家用净水器实质上是给水深度处理的小型化,其主要处理对象是自来水 中的浊度、色度、异嗅和有机物等。它一般由预过滤(粗滤)、吸附、精滤(微过滤、超过滤、反渗透)等三部分 组成。其中吸附(通常采用活性炭吸附)和精滤是去除水中有机物、异嗅和色度的主要手段,客观存在的运行情况 直接影响净水器的出水水质。家用净水器的服务对象是千家万户,但由于使用地区的水质,水压条件差异很大,使 用者又缺乏必要的操作知识,而目前的产品设计无法应付千变万化的情况,因此净水器的生产厂家应考虑到让使用 者掌握一定的专业知识,规范化的安装和操作净水器,使出水水质达到理想的效果,让使用者放心。
