【摘要】

：

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.

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
