自升式平台深水化改造的新模式及其可行性分析

针对我国现有自升式平台存在的不能满足深水域勘探开发的要求以及造价过高等问题,提出一种自升式平台深水化改造新模式——分体坐底自升式平台,在基本不改变原有平台结构的基础上,通过增加可沉浮平台下体,使作业水深增加50m以上,而造价比同工作水深的常规自升式平台低得多。文章介绍了该分体坐底自升式平台的结构方案、作业工况及操作程序,分析了该平台的技术可行性和经济可行性,并提出了深入研究和具体实施需要解决的问题。     

不同灌溉条件下的水稻需水规律及水分生产率分析

稻田需水量包括植株蒸腾、棵间蒸发、田间渗漏3部分。研究表明，水稻在充分供水条件下所形成的蒸腾量中包含了一部分无效蒸腾，无效蒸腾量的减少不会影响作物的生长发育，反而会有不同程度的增产和优质效应。节水灌溉技术的推广产生了明显的经济与社会效益。结合当地实际情况采用3种常见的灌溉方式探讨了不同灌溉方式下水稻的需水规律、灌概定额和生产率的差异，为水稻节水高效栽培提供理论与技术依据。     

三江平原水利综合规划的重新编制问题

实施取水定额管理的几个关键问题探讨

通过对全国23个省级单位出台的用水定额标准进行分析，指出目前定额管理存在6个主要问题：一是概念模糊，二是制定方法不统一、不规范，三是定额标准体系不完善，四是可操作性较差，五是计量系统不完善，六是缺乏取水定额管理信息化平台。提出应采用“取水定额”这一表述，并提出了取水定额的体系，包括基础计量体系、定额制定体系、信息链体系、定期更新体系4部分。明确了取水定额管理体系建设主要内容应包括：法律法规体系、定额制定体系、水价管理体系、信息通道体系。

蒸汽凝结水除油试验研究

介绍了利用类萃取技术进行蒸汽凝结水除油的过程。利用具有亲油功能的HOL-100树脂,经过试验和工业应用证明,萃取除油可以达到1．0mg/L以下,可满足炼油化工装置锅炉用水对含油量的要求。HOL-100树脂具有在高温状态下(120℃)除油的特点。通过标定考核,萃取除油技术是一项节能、节水、环保措施,可在中石油和中石化企业推广应用。     

Influence of influent tributaries on water quality changes in Lake Mogan, Turkey

Lake Mogan, located in the steppes of central Anatolia, is a vital Turkish ecological system, in terms of its water resources, flora and fauna. The lake also is a unique recreational area for Ankara, the capital of Turkey. However, the lake is currently threatened by severe pollution, being under the risk of serious degradation because of (i) uncontrolled urbanization; (ii) point and non‐point source pollution; (iii) inefficient sewerage systems; (iv) sediment transportation and pollution via influent creeks to the lake; (v) uncontrolled soil erosion in its drainage basin; (vi) inappropriate flood control measures; and (vii) severe degradation of the natural wetlands within its drainage basin. This study evaluates the influence of its influent creeks on the water quality of Lake Mogan, mainly because the creeks are believed to be responsible for the major pollutant load reaching the lake, and because the extensive database documenting this situation has not previously been critically evaluated. Accordingly, this study reviews (i) change in the water quality of Lake Mogan between 1993 and 2002; (ii) the water quality classification of the major influent creeks feeding Lake Mogan; and (iii) the influence of the influent creeks on the water quality of the lake between 1993 and 2004.     

Testing multi-characteristic product capability indices

Recently, studies associated with testing the quality and performance of each process for a product with multi-characteristics are proposed more often. However, most studies are limited to discussing one single type of quality characteristic. Practically, a multi-characteristic product is potentially composed of three types: smaller-the-better, larger-the-better, and nominal-the-best. In this paper, we propose an integrated product capability index which considers these three different types of quality characteristics. According to the theory of testing hypothesis, we develop a testing procedure for the product capability index to judge whether the process capabilities of total quality characteristics meet the customers’ demands. In addition, the relationship between the product capability index and the yield of the entire product will be introduced. Finally, an example is provided as a practical application.
