500对应0.35, 150对应0.45 中间270内插得Tg=0.35+(270-500)/(150-500)*(0.45-0.35)=0.4157, 罕遇时Tg=0.4157+0.05=0.4657,反过来内插也一样,150对应0.45, 500对应0.35 中间270内插得Tg=0.45-(270-150)/(500-150)*(0.45-0.35)=0.4157 Tg=0.4157+0.05=0.4657是不是无答案
Tg=0.4157+0.05=0.4657,反过来内插也一样,150对应0.45, 500对应0.35 中间270内插得Tg=0.45-(270-150)/(500-150)*(0.45-0.35)=0.4157 Tg=0.4157+0.05=0.4657是不是无答案
