Webb13 apr. 2024 · A = − T 2 d R / R d T = − E a / k is the temperature coefficient of resistance for the bolometer,. E a and k denote the activation energy and the Boltzmann constant,. T FPA (K) is the temperature of FPA (correlated with the ambient temperature),. R a0 and R b0 are the resistances of active and blind microbolometer at the temperature T 0 (K),. T r … Webb解:(1)原式=-18a 2 +4a-10-4a+6=18a 2-4, 当a=-时,原式=18×-4=-2; (2)原式=4x 2-4xy+y 2-2x 2 +4xy-2y 2 =2x 2-y 2 , 当x=-,y=-2时,原式=2×-4=-3 . 分析:两个小题都是需要先去括号,合并同类项,将原代数式化简,再代入求值. 点评:此题考查整式的化简求值.注意去括号时,当括号前面是负号,括号内各项 ...
