(1)优化施工方案和工作流程。项目的工作重点是对工程项目工作流程的优化、工程方案的改进,把人力资源科学合理的分配运用,这样能够减少和降低投入成本。当原材料的价格上升、劳动力的报酬增加、成本增加时,需要及时的制定对应的处理措施。在电气设备安装之前,要全面掌握安装过程中的技术重点和难点,对项目实施的流程、工作内容制定科学的控制措施,对项目的进度管理和监督需要成立专业的工作小组。当监督小组发现项目进程与计划有偏差时需要提出补救措施和方案,及时调整计划,满足工期目标。
(2)协调质量控制与进度控制的关系。施工单位应抽调精干人员,组建一支结构设置合理、人员素质较高和从业丰富的项目部。项目部应该严格执行“质量零缺陷、管理新起点”的目标和要求,对所有的电气设备安装实施科学化管理。项目部人员需要以项目合同作为依据,组织监督管理小组对建设过程中的安全、质量、进度、费用等实时监督管理,确保标准化和精确化管理。
(3)优化设备节能评价体系。在运行管理方面,应该大力提倡采用节能的运行方式,要加强运行管理机制,使得在电气系统运行的过程中充分地考虑节能运行方案。根据以上各项指标,将建筑地区的特点相结合,构建建筑电气系统节能评价的指标体系。还有一些评价指标,因为没有得到相应的测试数据,而无法列入评价体系,例如,水泵、风机的有效功率比、电机功率比、总效率等。
目前,水利工程产业正在大力发展。在国内,对水利工程的建立在技术上仍有欠缺,高素质的人才也依旧匮乏。但在很大程度上,设计者们已经开始重视生态问题,将生态学与水文学有效结合起来,成为了设计者解决问题的突破口。在国内,我们在充分掌握自然规律、自然界的运行准则的前提下,应借鉴西方国家的先进技术和经验,立足国情自主创新,注重人才的培养,使专业化和先进的技术融入施工作业中;应为水利水电工程的发展储备大量可用人才,在生态平衡的前提下,发展水利水电工程,走科学化、可持续化的发展道路,从而保证水利工程建设与生态环境协调发展,推动中国水利事业的快速发展,更好地造福人类。
the importance of water(一
水的重要性(一)
the importance of water(一)
it is well-known that water is indispensable in existing, in producing and in living. and we should
not waste of a drop of water.
众所周知,在生产和生活中水是必不可少的。我们不应该浪费一滴水。
first, water is definitely important for life. as is known to us all, water is necessary to sup
port life. without water, human beings, animals and plants cannot exist at all.
首先,水对生命是非常重要的。众所周知,水是维持生命所必需的。没有水,人类,动物和植物都不复存在。 second, water is also significant for producing. for one thing, industrial production needs a lot of water, such as using water to generate electricity. for another, agricultural production is also in need of water, especially in irrigation.
随着信息技术的不断完善,电气自动化作为电气信息领域的新兴学科,受到了人们的广泛关注,也与人们的日常生活和工作息息相关。电气自动化系统不仅能够提高电力系统的工作效率,还在运行成本、劳动生产率以及改善工作条件等方面发挥着非常关键的作用。近年来,绿色工业革命逐渐兴起,当前经济建设最重要的目标便是节能减排。而先进的自动化技术成为了推动各行各业节能减排的有效手段。随着全球化的不断发展,只有掌握节能的高新技术产业的主导权,才能在未来竞争激烈的全球经济中占有一席之地,才有权利去主导未来的全球经济。对于电气自动化系统而言,不断扩大的城市电网,不断增容的电力系统,是其必须运用大量的变频器和整流器等,而这些会导致其产生大量的谐波,对电网造成极大的威胁。为了消除谐波,并达到节能的效果,电气自动化需要从变压器、无功补偿、有源滤波器等方面进行考虑,从而使电气系统在运行过程中实现节能的目标。
Is it good for students to do some housework
Secondly, to do some housework can keep you healthy and strong ,some hard housework can be regarded as a kind of physical exercise。
Finally, to do some housework can share your parents’ work 。They must be happy if you say” Have a rest ,and I will do the housework”
So I think it is good for students to do some housework。
这是好学生做一些家务其次,做一些家务能够让你保持健康和强壮,一些硬家务可以看作是一种体育锻炼。
最后,做一些家务可以分享您的父母的工作。他们必须高兴,如果你说“休息一下,我会做家务”因此,我认为这是为学生好做一些家务。
as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
