郑州电网2012年迎峰度夏需求侧管理措施

2012年迎峰度夏期间,郑州电网负荷屡创历史新高,由于郑州市区一些规划新建变电站投运滞后,市区电网负荷红橙黄重载区域未得到有效缓解,迎峰度夏高峰时段,局部地区仍出现主变、配线过载现象。郑州供电公司按照河南省电力公司统一部署,加强电力需求侧管理,合理安排用户错避峰,在夏季高峰负荷电力供应不足的情况下,最大限度地满足电力客户平稳有序用电。

Outcomes one year after a road accident: Results from the ESPARR cohort

Objective

Reducing the rates of death, trauma and sequelae associated with road accidents is the prime goal of road safety authorities, and success requires having data on victims’ outcomes in the long term. The present study examined the outcome of adult road accident victims one year after their accident.

Design

A follow-up study.

Methods

The cohort comprised 886 injured road-accident victims, aged ≥16 years, and living in the Rhône administrative Département, France (taken from the ESPARR Cohort). Data were collected on victim characteristics at the time of crash, and self-reported outcomes one year later. The population of respondents at the one-year questionnaire follow-up was divided into two categories according to injury severity, as mild-to-moderate (M.AIS < 3) or severe (M.AIS 3+). Qualitative variables were compared between these 2 groups using Chi² or Fisher exact tests.

Results

At one year post-accident, 45% of the mild-to-moderate injury group versus only 20% of severely injured subjects reported full recovery of health (p < 0.001). 20% of the cohort, as a whole, reported permanent pain. More than half of the severely injured subjects reported that the accident had had an impact on the everyday life of their family; this was twice as many as in the mild-to-moderate injury group (55% vs. 22%). Most of the severely injured reported impact on leisure, projects and emotional life: 20% reported relational difficulties in the couple, 16% reported impaired sexual life, and the rate of separation was significantly higher than in the mild-to-moderate injury group (5% vs. 1%; p < 0.001). Mean time off work was significantly longer in the severe injury group: 245 ± 158 days vs. 75 ± 104 days (p < 0.001); and 32% of the severe injury group (p < 0.001) who had stopped work had not returned at 1 year, compared to 5% of the mild-to-moderate injury group.

Conclusions

One year after a road accident, the consequences for victims remain significant. In terms of physical impact, pain frequently persists, impairing daily life for many. There is an elevated rate of chronic PTSD (post-traumatic stress disorder) and a non-negligible impact on affective and occupational life.     

2006年我国磷肥、硫酸行业生产消费情况概述

介绍2006年我国磷肥、硫酸行业生产和消费情况。2006年磷肥产量达1 210万t P2O5,高浓度磷肥产量占67.8%,磷肥自给率已达99.8%,磷肥行业利润率下降,亏损企业增加,2007年磷肥产量将会平稳增加。2006年硫酸产量达5 044万t,硫磺制酸产量已占44.3%,我国硫资源对外依存度已超过55%,硫酸产业集中度进一步提升,装置向大型化发展,2007年我国硫酸能力、产量、消费量将增长。     

宿州地区HDD、CDD值的变化规律与分布特征

本文采用典型气象年法对宿州地区1986-2015年气象参数进行计算分析,得出HDD、CDD值。采用平均年法对HDD、CDD值的逐年变化规律与变化趋势及年分布特征进行了分析研究。定义了基于HDD/CDD值的冷热强度与程度的概念。结论如下:典型气象年宿州地区HDD、CDD值为2009.4℃·d和155.8℃·d。1月采暖度日数占全年采暖度日数1/4。7月制冷度日数占全年制冷度日数近1/2。HDD值在30年中呈下降趋势,冷强度极值增加,相同冷强度下的冷程度减小。CDD值呈上升趋势,热强度极值增加,相同热强度下的热程度增加。过渡月份异常天气的频次增多,冷热强度增大,16℃冷强度值为5.9℃·d与26℃热强度值为1.0℃·d。     

土壤水资源及其计算方法浅议

天然降雨是土壤水的主要来源之一,将土壤水列入资源的范畴,但它不宜与地表水和地下水并列作为水资源的一个组成部分加以评估。蓄存在包气带土层中的土壤水的来源及其数量,其有效性,除自然因素外,更多是决定于人为的因素,过分夸大土壤水作为资源的属性容易作出错误的判断;估算一个水文年的土壤水资源量时,不能以整个水文年度作为运算时段,而应该针对每一个更新周期、按照降雨量的大小以及降雨间歇期的消耗情况(农田蒸散发)逐次计算土层的储存增量,然后进行累加,文中推荐采用水均衡法和数值计算相结合的估算方法;本文认为在以往水资源规划中已考虑了"土壤水资源"的现实,没有必要专门开展土壤水资源的评价。
