【摘要】

：

建(构)筑物爆破拆除工程中,倒塌的钢筋混凝土结构以较高的速度冲击地面时将诱发地震波,对地震波的振动强度进行预测是分析拆除工程对周边环境影响程度并确定控制措施的前提.基于土体在强冲击作用下的塑性变形特征,碰撞过程的动量守恒理论和量纲分析法,构建了触地接触面较宽的塌落振动预测模型.通过工程案例对计算模型的有效性进行了验证.算例表明,该模型计算精度基本满足工程设计需要,且简便易用.

Comparison of nominal and standardized catch per unit effort data in quantifying habitat suitability

In the western and central Pacific Ocean, upper strata waters exhibit highly dynamic oceanographic features under ENSO variability. This has been proved to be responsible for the dynamic change of both abundance and zonal distribution of skipjack tuna (Ka

Performance evaluation of fixed-station sampling design for a fishery-independent survey with multip

Fixed-station sampling design was widely used in fishery-independent surveys because of its characteristics of convenient sampling station setting, but the non-probabilistic (fixed) nature made it more uncertainty of drawing inferences on population. The

CuO/ZnO复合纳米结构的制备及其气敏性能研究

用简单的一步水热法合成了CuO/ZnO复合纳米结构,通过改变溶液中Cu离子的浓度得到不同CuO含量的样品.用扫描电镜、X射线衍射仪等表征了样品的形貌和结构,用智能气敏分析仪测试了样品对乙醇气体的响应特性.结果表明,相对纯ZnO,CuO/ZnO复合纳米结构对乙醇气体的响应有明显的增强.溶液中Cu离子与Zn离子摩尔比为3:5时,合成样品的气敏性能最好,它在最佳工作温度200℃下对体积浓度为100×10-6的乙醇的灵敏度为55.3.这种气敏性能的显著增强可以归因于样品比表面积的提高和p-n结的形成.
