| 1. | Cost comparisons for desalted water are often made to existing water supplies which did not include a full , fair cost - benefit analysis when the were developed 去盐水的价格比较在于现有水的供给状况,此种供给并不一定是全部、公平的价格利益分析,当它们还在发展中。 |
| 2. | According to the technological process and the using equipment , the project is planned to take advantage of present water , electric , steam and site to establish a producing workshop 根据工艺流程,结合合作要求,本项目计划利用现有水电汽,在现有厂区内建一座生产车间。 |
| 3. | This paper is combined with the project of research of underwater acoustic network technology . first , we study and research existing uan and its protocols at home and abroad 首先学习、研究了现有国内外有关通信网络及其协议,并对国外现有水声通信网络进行了较深入的研究和分析。 |
| 4. | The existing analysis method of the exploitation potentiality of water resources has ome serious shortcomings , so it cannot act as the foundation for the exploitation and utilization planning of water resources 摘要现有水资源开采潜力分析方法存在严重缺陷,不能作为水资源开发利用规划的依据。 |
| 5. | The goal of policies set out during the period from current water resources management system to water right system is to form the water right system and market without possible breaking of exitsting interests status 从现有水资源管理体系向水权体系过渡期间的政策目标是,在尽量不打破现有利益格局的前提下,形成水权制度和水权市场。 |
| 6. | Yet the real challenge is to focus attention on action - oriented activities and policies that ensure the long - term protection of available water quantity and quality and sustainability of water resources utilization , including sanitation 不过,真正的挑战是集中注意面向行动的活动和政策,以确保长期保护现有水资源的质量和数量,以及包括卫生在内的水资源的可持续使用。 |
| 7. | Phenomena , such as flow field confusion and slagging etc . have occurred in the practical process of cyclone burner for coal - water slurry ( cws ) firing , on this basis a study on aerodynamic field of cws cyclone burners had been carried out through cold state experiments in the laboratory , then the influence of burner ' s structure properties upon the said flow field had been carried out , and expected to find more reasonable structure of the burner was found . in my study the focus is on the affection of cone and cyclone intensity in the condition of infinite and finite fields 本文着重研究现有水煤浆旋流燃烧器的旋流叶片角度,一次风扩口的长度以及角度对旋流燃烧器出口流场的影响,通过流场的比较,以期得到性能较好的旋流燃烧器。考虑到水煤浆燃烧器中心的水煤浆射流对于其空气动力场的影响,本文在实验室冷态实验研究的基础上,模拟水煤浆射流,研究其对燃烧器空气动力场的影响。 |
| 8. | The agricultural production holds an important position in baoding area , winter wheat and summer corn are the main grain crops and cotton is the main cash crop . the water resources used in agriculture include rainwater resources used directly by crops and surface water resources or underground water resources which is used through irrigation . there have been lots of rainwater waste because of lacking in research on rainwater resources utilization and in perfect engineering technology in baoding area . to make full use of rainwater is important to alleivate the water resources crisis and improve the ecological environment , the main objectives can make more rainwater turn into soilwater that can be utilized by crops directly and decrease the crops requirments for the surface and ground water resources 用于农业生产的水资源包括直接利用的雨水资源和通过灌溉补充的地表水资源和地下水资源。目前,保定市对直接用于农业生产的雨水资源尚未进行深入细致的研究,而且雨水资源的利用工程技术措施尚不完备,这种情况造成了雨水资源的浪费。显然,充分利用雨水资源,即尽可能多的把天然降水转化为可被作物利用的土壤水,减少作物对现有水资源(地表水资源和地下水资源)的需求,对于缓解保定市水资源供需矛盾,改善水环境与生态环境有重要的现实意义。 |
