由于衍生工具本身的复杂性质和现行会计制度对金融工具采用混合计量属性所导致的经济后果,对衍生工具进行会计定义是较为复杂的问题。考察了美国会计准则委员会(FASB)有关准则关于衍生工具会计定义,并分析了美国GAAP与国际会计准则相关规定之间的异同,认为二者尽管存在差异,但IAS39中的许多关于衍生工具会计的规定无疑模仿或借鉴了美国GAAP。

外形结构和材料对绝缘子的污秽闪络特性有较大影响。为此,采用恒压升降法,在高海拔地区进行了大吨位长棒形瓷绝缘子的直流人工污秽试验,通过测量泄漏电流和污闪电压,拍摄电弧发展照片,对比研究了芯棒涂覆强疏水型长效防污闪涂料H-PRTV对长棒形瓷绝缘子直流污闪特性的影响。结果表明,芯棒涂覆H-PRTV后,长棒形瓷绝缘子直流污闪电压明显提高,电弧发展过程明显缩短,临闪前大幅值泄漏电流脉冲减少,整个污秽闪络过程有延缓的趋势。
