海岸带污染物联合毒性的预测及评价 [PDF]

, 2015
海岸带区域的污染具有内容广泛、状况复杂和管理决策难度较大等特点。由于海岸带环境中的化学污染物往往以混合形式存在,因此单一化学品高剂量暴露下的生态毒性研究结果难以适用于环境中低剂量混合物的生态毒理效应诊断及风险评价。传统的风险评价体系多是在实验室模拟条件下以单一物质的急性或慢性毒性试验为依据,往往很难正确反映实际环境中污染物混合存在时的生态行为及环境危害。随着技术的进步和人类认识能力的进一步提高,研究者们已经聚焦于发展数学模型用以预测及评价化合物的联合毒性 ...

某地铁站台膜结构平均风压分布系数数值模拟研究

Jianzhu Gangjiegou Jinzhan, 2010
膜结构比较轻柔,为风敏感性结构。膜结构在风荷载作用下的变形和振动会影响到结构表面的风压分布情况,即会产生流固耦合效应。在结构设计中,平均风压分布系数在强度设计中具有非常重要的作用。本文采用通用有限元软件ADINA进行了考虑流固耦合作用的地铁站台屋盖膜结构平均风压分布数值模拟。数值模拟简洁、高效,可以供复杂工程的风荷载设计参考。

国电电力佳木斯两风电项目获核准

Dianci bileiqi, 2008
国电电力佳木斯郊区两风电项目,日前同时获黑龙江省发改委核准。至此,国电和风公司在黑龙江核准的风电项目累计达到3个,核准容量达到1.5×105 kW。刚刚获得核准的猴石、汤原两个风电项目,位于佳木斯郊区,风电场规划容量各为49.5 MW,各拟安装33台1500 kW的风力发电机组,计划2009年底投产发电。其中猴石风电项目工程总投资51 101万元;汤原（渠首）风电场项目总投资51 425万元。
