易黎灵4042由电压大小判断虚短虚断 -
富柿肺18939031260 ______ 虚短和虚断是在运算放大器电路中用于简化运算而采取的一种近似方法.U+≈U-;IB≈0.其应用条件是两个:一、运算放大器的开环电压增益(放大倍数)很大,可以看作是无穷大;二、运算放大器的输入阻抗很大,可以看作是无穷大...

易黎灵4042已知等差数列an中公差d<0若a4Xa6=24.a2+a8=10.则该数列前n项和Sn的最大值?
富柿肺18939031260 ______ a4*a6=24,a4+a6=10,得到a4=6,a6=4,通项公式=10-n,前n项和sn=(19n-n2)/2,所以第9项或第10项取得的sn最大,Snmax=45
