2. 截止：1.截止(cut off)状态:如图5所示,当三极管之基极不加偏压或加上反向偏压使BE极截止时(BE极之特性和二极管相同,须加上大于0.7V之正向偏压时才态导通),基极电流IB=0,因为IC=βIB,所以IC=IE=0,此时CE极之间相当于断路,负载无电流.

3. 截断：一般黑体辐射的空腔是他允许各种波长的电磁波在空腔内形成驻波.但是若这空腔的尺寸大小变的很小的时候,不可能再允许各种波长的电磁波,只能允许部分特定波长的电磁波在金属空腔内形成驻波.而且波长大於1/2空腔长度的电磁波,都会被截断(cut off)而不允许.这种现象,

4. 临界值：临界值(CUT OFF)计算:临界值=阴性对照孔平均值 0.15阴性判定:样品OD值 临界值(CUT OFF)者为牛狂犬病毒抗体阴性阳性判定:样品OD值≥ 临界值(CUT OFF)者为牛狂犬病毒抗体阳性
