某机电安装公司采用EPC方式承包了一项石油化工工程，在设备订货采购阶段，该机电安装公司通过投标询价向某设备制造厂订制了一批塔、容器类非标设备，包括3台分段到货的塔和8台整体到货的卧式容器。安装公司项目部采购部门对该批非标设备进行了监造，编制了监造大纲。监造大纲内容有：(1)监造计划;(2)进行控制和管理的措施;(3)监造过程。并派出了监造工程师驻厂监造。 

按照设备采购合同，塔、容器分批到货。第一批到货设备是2台分段到货的分馏塔，运抵施工现场后，安装公司项目部组织相关质检、技术人员进行了现场验收。在检查验收设备时发现塔存在较多缺陷，包括：表面焊接缺陷如凹陷、焊瘤、飞溅等严重;塔体外表面有划痕、敲击伤痕等损伤，表面有锈迹，内部有积水腐蚀现象，分段处的端口有多处凹凸不平的撞击损伤。建设单位表示不能通过验收，设备应予报废。 

在对缺陷进行检查、鉴定后，监理单位提出，现有缺陷可以得到处理，构不成设备报废，由于安装工程需要，建议采取“紧急放行’’措施，该塔进入安装程序。对存在的质量安装公司项目部采购部门吸取了教训，修订了非标设备制造过程监造质量控制要点，加强了后续非标设备的监造工作，使后续出厂的设备质量符合质量要求。

问题:

1.背景中监造大纲的内容是否齐全?若不齐全还需补充哪些内容?

2.分段到货设备的现场验收主要有哪些检查检验项目?

3.质量问题的处理方式有哪些?本次“紧急放行”的依据是什么?对工程施工有什么实际作用?

4.对于塔的制造质量问题的主要责任单位是谁?应承担什么责任?驻厂监造工程师有无过错?若有过错应承担什么责任?

5.非标设备制造过程监理质量控制要点有哪些?

About fifty years ago, plant physiologists set out to grow roots by themselves in solutions in laboratory flasks. The scientists found that the nutrition of isolated roots was quite simple. They required sugar and the usual minerals and vitamins. However, they did not require organic nitrogen compounds. These roots got along fine on mineral inorganic nitrogen. Roots are capable of making their own proteins and other organic compounds. These activities by roots require energy, of course. The process of respiration uses sugar to make the high energy compound ATP, which drives the biochemical reactions. Respiration also requires oxygen. Highly active roots require a good deal of oxygen.The study of isolated roots has provided an understanding of the relationship between shoots and roots in intact plants. The leaves of the shoots provide the roots with sugar and vitamins, and the roots provide the shoots with water and minerals. In addition, roots can provide the shoots with organic nitrogen compounds. This comes in handy for the growth of buds in the early spring when leaves are not yet functioning. Once leaves begin photosynthesizing, they produce protein, but only mature leaves can "export" protein to the rest of the plant in the form of amino acids.
