评先风波

前年底,A矿“特红标杆安全示范班组”评选揭晓。不出所料,B车间C班组以其一流的生产经营指标,理所当然地夺取了这面全矿唯一的锦旗。再过3天,矿里将举行隆重的授旗表彰大会。消息传出,C班的一帮哥儿们甭提有多高兴了,大家嘴合不拢,眼成一条缝……     

矿区“安全哨兵”刘昌

安全员被称为矿工生命的＂守护神＂。正是安全员尽职尽责的专业精神,保障了每一名矿工的安全,为矿区、矿工筑起一道道安全堤坝。相比＂守护神＂这一称号,武钢乌龙泉矿安全督查队的督查员刘昌却更喜欢别人称自己为＂安全哨兵＂。     

崇明东滩湿地围垦区芦苇生物量影响因素初探

在对崇明东滩湿地围垦区土壤和芦苇生长状况进行调查的基础上,探讨了受潜水位波动影响的土壤环境因子对芦苇群落生长的影响.结果表明:(1)由于潜水位波动的幅度和时间不同,样地间土壤含水量存在显著差异(P1,2=0.004,P1,3=0.001,P2,3=0.040),进而导致受土壤含水量影响较大的芦苇株高和单株叶面积不同,土壤含水量高的样地,其芦苇株高和单株叶面积也达到最高值;(2)土壤全氮含量对芦苇密度、地上生物量和地下生物量有明显影响.     

武钢乌龙泉矿打“补丁”保安全

<正>本刊讯进入2014年2月份以来,武汉钢铁(集团)公司乌龙泉矿围绕今年安全工作重点,找准安全切入点,实施三项举措"打补丁",确保安全生产。打好安全意识"补丁"。针对极少数职工安全意识淡薄、心存侥幸的实情,把"只有不到位的管理,没有抓不好的安全"理念贯穿于安全生产全过程,提出"零缺陷、零失误、零隐患、零违章"的"四零"目标,

多金属氧酸盐电催化降解染料废水的研究

采用IR和XRD等手段对磷钼酸(PMo12)和3,3',5,5'-四甲基联苯胺(TMB)形成的电荷转移配合物(TMB)3PMo12进行表征,结果表明配合物中的杂多阴离子仍保留着Keggin结构.将配合物负载于γ-Al2O3上制备(TMB)3PMo12/γ-Al2O3负载型催化剂填充于电化学反应器中,考察电催化氧化体系降解酸性大红3R染料废水的效果.研究表明,(TMB)3PMo12/γ-Al2O3催化剂对酸性大红3R废水显示了良好的电催化活性,催化剂填充量为50g,负载量为0.6%时,在pH值为4,槽电压15.0V,曝气量0.14m3/h,极板间距3.0cm反应条件下,60min后,色度去除率达到79.7%,去除效果较传统二维平板和三维电解槽更高.     

植被净初级生产力对气候变化的响应研究——以黄土高原燕沟流域为例

Vegetation net primary productivity (NPP) is a sensitive indicator to characterize the response of terrestrial ecosystems to the climate change. Projections of the NPP changes of the Loess Plateau under future climate scenarios have great significances in revealing the interactions among terrestrial ecosystems and climatic systems, as well as instructing future vegetation construction of this region. Here, we carried out a case study on the Yangou watershed in the Loess Plateau. Using the vegetation-producing process model (VPP) established for such small watersheds, we simulated the NPP of the Yangou watershed under different scenarios of climate changes. The results showed that the NPP significantly increased with the precipitation increasing and evidently decreased with the temperature increasing where the climate change occurred in the whole year or in the summer half year. However, where the climate change occurred in the winter half year, the increased precipitation had little effect on the NPP, and the increased temperature significantly reduced the NPP. There were clear differences among the response sensitivities of different vegetation types with trees and shrubs were more sensitive to the changes in temperature and precipitation than crops and grasses. Currently, the most favourable climate change scenario to the NPP in the Yangou watershed was T0P15 under which the precipitation increased by 15% and the temperature did not changed, in the whole year; in the meantime, the most unfavourable climate change scenarios was T2P-15 under which the precipitation declined by 15% and the temperature increased by 2℃, in the whole year.
