在传统凯恩斯经济学模型中利率是货币政策最为重要的传导渠道,但从我国2000~2005年月度数据的实证分析来看,中央银行货币供应量m2的增减很难引起实际利率的变动,而且实际利率的变动也不是引起固定资产投资变动的主要原因,对消费的影响力度也极小,从而说明我国货币政策的利率传导渠道存在“硬阻”。

采用碳纳米管阵列(CNTA)与环氧树脂(Epoxy)溶液共混制备CNTA/Epoxy复合材料.将CNTA分散于Epoxy溶液中,在60℃的温度条件下固化4h,将固化后的Epoxy浸润在CNTA薄膜中;CNTA薄膜中的碳纳米管仍然能保持整齐排列,以此提高复合材料沿轴线方向上的热导率.其中,轴线方向为碳纳米管的管轴方向.实验发现,CNTA/Epoxy复合材料的热导率在90℃时提高到2.24 W/(m·K),相当于纯Epoxy热导率的10倍左右.复合材料的电导率仍保持在一个相对较低的值,为10-8 S/***相对于大多数的纳米填料能够显著增强复合材料的热导率,同时能使复合材料保持一定的绝缘性,满足这种热界面材料在电子封装上的应用条件.
