项目融资的定义 广义的定义 所有为了建设一个新项目、收购一个现有项目或者对已有项目 进行债务重组所进行的融资活动都可以被称为项目融资 美国财务会计标准手册》(FASB)的定义 是指对需要大规模资金的项目采取的融资活动借款人原则上 将项目本身所拥有的资金及其收益作为还款资金来源,而且将 其项目资产作为抵押条件来处理。该项目事业主体的一般性信 用能力通常不被作为重要因素来考虑

功率管是电路中最容易受到损坏的器件。损坏的主要原因是由于管子的实际耗散功率超过了额定数值。而晶体管的耗散功率取决于管子内部结温T。当T超过允许值后,电流将急剧增大而使晶体管烧坏。一般情况下,硅管允许结温为120~200℃,锗管为85℃左右(具体标准在产品手册中给出)
