题目内容
[背景] 某耐火材料厂新建厂区工程，主要单体为一重钢结构多层厂房工程，地下部分为混凝土灌注桩基础，地上部分柱为钢管混凝土，其他构件均为H型钢构件，钢构件的连接方式主要为高强螺栓连接。 钢构件加工过程中，驻加工厂监理发现个别构件焊接时出现咬边，经过施工单位的科技攻关，得以解决。 制作完成、并经检测合格的构件所有外露部位均喷涂底漆后运至施工现场，现场尺寸校验后进行拼装。高强螺栓连接时先初拧至施工扭矩的50%左右，对接合件进行校正，消除接合件的变形、错位和错孔后，再复拧达到紧固。高强螺栓安装时从中部向四周逐个进行，初拧及终拧从四周向中心进行，并保持四个方向对称拧紧。 钢结构子分部工程质量验收合格，在工程竣工验收通过后3个月之内，施工单位按时将工程档案送交当地城建档案管理机构。 试分析可能出现咬边的主要原因并简述处理方法。

The entertainment industry and technology companies have been warring for years over the dazzling ability of computers and the Internet to copy and transmit music and movies. A crucial battle ended this week with a ruling by America"s Supreme Court in favour of copyright holder and against two companies that distribute peer-to-peer (P2P) software, which lets users share files online with others. The court"s decision, though ostensibly a victory for content providers, is nevertheless unlikely to stamp out file sharing—much of which will continue from outside America—or stop the technological innovation that is threatening the current business models of media firms. The court was asked to decide whether two firms, Grokster and StreamCast, were liable for copyright infringement by their customers. Two lower courts had said that the firms were not liable, citing a 1984 ruling in favour of Sony"s Betamax video recorder. This held that a technology firm is immune from liability so long as the device concerned is "capable of substantial noninfringing uses". The court did not reinterpret the 1984 decision in light of the Internet. Instead the justices ruled that the case raised a far narrower issue: whether Grokster and StreamCast induced users to violate copyrights and chose not to take the simple steps available to prevent it. Such behaviour would make the firms clearly liable for copyright infringement and end their immunity, even under the Betamax standard. The court reasoned that there were sufficient grounds to believe that inducement occurred, and sent the case back to lower courts for trial. Although the Grokster decision will probably not squelch innovation as much as many tech firms fear, it should certainly make IT and electronics firms more cautious about how they market their products—and quite right, too. But the Supreme Court"s narrow ruling makes this unlikely—indeed, the justices noted the technology"s widespread legitimate use. Yet their decision will surely embolden the entertainment industry to pursue in court any firms that they can claim knowingly allow infringement. This could kill off some small innovative start-ups. On the other hand, the ruling could also provide legal cover for tech firms with the wit to plaster their products with warnings not to violate the law. But judged from a long-term perspective, this week"s victory for copyright holders seems likely to prove a Pyrrhic one. The Internet and file sharing are disruptive technologies that give consumers vastly more ability to use all sorts of media content, copyrighted or not. Surely entertainment firms must devise ways to use this technology to sell their wares that will also allow copyright to be protected. So long as technology continues to evolve in ways that enable legitimate content sharing, piracy will also probably continue to some degree. Happily, in this case the piracy seems to have prompted content fir-rug to compete by offering better fee-based services. The challenge for content providers is to use new technology to create value for customers, and to make those who use content illegally feel bad about it. The ruling of America"s Supreme Court
[背景] 某写字楼建设项目，建设单位与施工单位签订土建和装饰装修施工合同，建设单位委托监理单位对该工程土建施工和装饰装修进行工程监理。在该工程装饰装修过程中发生了如下事件： 事件一：装饰装修合同中规定5000m2的花岗石石材由建设单位指定厂家，施工单位负责采购。当第一批石材运到工地时，施工单位认为：由建设单位指定用的石材，在检查产品合格证后即可用于工程；而监理工程师认为必须进行石材放射性检测。经抽样检验发现石材质量不合格。 事件二：为了赶工期和避免人员窝工，在屋面防水工程、室内轻质隔墙、安装管道和电气管线敷设、专业工程预埋件、预留空洞还未完工之前，施工单位就进行了室内抹灰、吊顶、裱糊、饰面板工程施工。 事件三：该写字楼外墙采用隐框玻璃幕墙，幕墙与主体结构采用后置埋件连接，因为幕墙构造需要，在填充墙上也采用后置埋件连接。在施工前，施工单位在现场室内混凝土构件上埋置了两块后置埋件，并委托施工单位直属的有专业检测资质的检测中心对这两块后置埋件进行了检测，作为后置埋件检测的依据。 事件四：在玻璃幕墙安装完毕后，由施工单位委托具备相应资质的检测机构对幕墙进行了“三性试验”检测，符合规范要求，于是对该幕墙工程施工质量进行了合格验收。 事件三中，为保证后置埋件与主体结构连接可靠，应对其进行何种检测施工单位委托的检测单位可否承担本工程的检测任务为什么施工单位检测的样本是否正确为什么
