正确答案:

指标:按照《生活饮用水卫生标准》 ( GB5749-2006)规定,出厂水浊度 <1NTU,我公司要求出厂水浊度控制在 0.09NTU以下出厂水浊度超标可能的影响因素。判断是否开车造成瞬间超标。再排除仪表故障,有无采样水等。检查清水池水位,沉积物也会造成低水位运行时出水浊度超标,短期处理增加进水量,清水池高水位运行,长期应考虑清洗清水池。 检查滤后水浊度情况是否超标,排除滤后水仪表故障,检查沉淀水浊度是否超标,是,同时加强冲洗滤池;增开滤池降低滤速。必要时将浑水排放。否,短期处理重点排查运行滤池,缩短运行周期,长期处理对滤池各项工艺参数重新测定,定期消毒等。若问题出在沉淀水浊度,应加强对沉淀环节的检查,水量突变、加矾设备、源水浊度突变、排泥不畅等。酌情采取加强排泥频次、加大矾量、减少进 水量等补救措施。

出现超标应及时作出处理并汇报记录,最后水质好转后,应将浊度仪清洗一下。

1 我市目前日最高用水量为 30 万吨 /天,我市目前现有两座水厂正在运行,每座水厂日处理量均可达到 30 万吨/ 天,且城市供水管网形成环状供水, 若单一厂区出现浊度超标则通知该超标厂区进行自查并停止供水,同时通知另一水厂增大出水量确保城市供水正常。

2.组织人员对超标厂区附近管网进行排污,通知厂区对加药,反冲洗等工艺环节进行自查,待清水库检测合格后,恢复厂区供水

案例资料:

近年来,随着人们收入水平的提高,旅游消费人群不断扩大。大学生假期旅游已成为时尚。李晓、王明、周梁是某高校大三学生,她们平时关系甚好。在李晓的动议下,三人经过与其家长重复沟通、商议,并在家长那里获取足够的旅游资金后,决定暑期在国内选择一家旅行社进行她们人生中第一次旅游消费活动。旅游消费活动对三人来讲毕竟是第一次,由于旅游花销较大,各个旅行社知名度、服务水准差异也大,旅游产品购买风险显而易见。三人开始分头了解、搜集相关旅行社的信息。经过看广告、网上查询,与有经历、经验的同学交流,去学校附近的旅行社咨询等调研后,她们决定选择A旅行社推出的“国内某一大城市经典游”项目进行旅游消费。A旅行社为改变旅游“产品”无法满足人们的多样化、个性化需求,暑假根据大学生的旅游需求特点,在不增加该项目费用的前提下增加了该项目的特色。比如在原旅游项目中增加郊外运动游(爬山、漂流)。在促销方面,推出有奖旅游销售,特等奖获得者可免费获得重大致育赛事门票两张(在此期间,该城市有国内足球甲A比赛)。但该旅行社的定价并不比其它旅行社的同类旅游“产品”高。三人暑期随团如期进行了旅游,旅行社按合同约定圆满提供了相应的服务。回校后李晓逢人便兴致勃勃地讲该次旅游的轶事,将该次旅游总结为一个字“爽”,俨然像该旅行社的一个推销员。

要求:请根据上述案例的描述,回答以下问题:

(1)说明该次旅游购买决策过程的三个主要角色。

(2)该购买行为属于哪种类型?为什么?

(3)描述购买决策过程。

(4)站在李晓的角度,简要写出购后行为分析。

Selling Digital Music without Copy-protection Makes Sense A. It was uncharacteristically low-key for the industry’s greatest showman. But the essay published this week by Steve Jobs, the boss of Apple, on his firm’s website under the unassuming title “Thoughts on Music” has nonetheless provoked a vigorous debate about the future of digital music, which Apple dominates with its iPod music-player and iTunes music-store. At issue is “digital rights management” (DRM)—the technology guarding downloaded music against theft. Since there is no common standard for DRM, it also has the side-effect that songs purchased for one type of music-player may not work on another. Apple’s DRM system, called FairPlay, is the most widespread. So it came as a surprise when Mr. Jobs called for DRM for digital music to be abolished. B. This is a change of tack for Apple. It has come under fire from European regulators who claim that its refusal to license FairPlay to other firms has “locked in” customers. Since music from the iTunes store cannot be played on non-iPod music-players (at least not without a lot of fiddling), any iTunes buyer will be deterred from switching to a device made by a rival firm, such as Sony or Microsoft. When French lawmakers drafted a bill last year compelling Apple to open up FairPlay to rivals, the company warned of “state-sponsored piracy”. Only DRM, it implied, could keep the pirates at bay. C. This week Mr. Jobs gave another explanation for his former defence of DRM: the record companies made him do it. They would make their music available to the iTunes store only if Apple agreed to protect it using DRM. They can still withdraw their catalogues if the DRM system is compromised. Apple cannot license FairPlay to others, says Mr Jobs, because it would depend on them to produce security fixes promptly. All DRM does is restrict consumer choice and provide a barrier to entry, says Mr Jobs; without it there would be far more stores and players, and far more innovation. So, he suggests, why not do away with DRM and sell music unprotected? “This is clearly the best alternative for consumers,” he declares, “and Apple would embrace it in a heartbeat.” D. Why the sudden change of heart? Mr Jobs seems chiefly concerned with getting Europe’s regulators off his back. Rather than complaining to Apple about its use of DRM, he suggests, “those unhappy with the current situation should redirect their energies towards persuading the music companies to sell their music DRM-free.” Two and a half of the four big record companies, he helpfully points out, are European-owned. Mr Jobs also hopes to paint himself as a consumer champion. Apple resents accusations that it has become the Microsoft of digital music. E. Apple can afford to embrace open competition in music players and online stores. Consumers would gravitate to the best player and the best store, and at the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to the iPod. Since only 3% of the music in a typical iTunes library is protected, most of it can already be used on other players today, he notes. (And even the protected tracks can be burned onto a CD and then re-ripped.) So Apple’s dominance evidently depends far more on branding and ease of use than DRM-related “lock in”. F. The music giants are trying DRM-free downloads. Lots of smaller labels already sell music that way. Having seen which way the wind is blowing, Mr Jobs now wants to be seen not as DRM’s defender, but as a consumer champion who helped in its downfall. Wouldn’t it lead to a surge in piracy? No, because most music is still sold unprotected on CDs, people wishing to steal music already can do so. Indeed, scrapping DRM would probably increase online-music sales by reducing confusion and incompatibility. With the leading online store, Apple would benefit most. Mr Jobs’s argument, in short, is transparently self-serving. It also happens to be right.
