〖1/1算式〗
    作业：求算式 0.8*(0.909*ln(319.45/363.15)-8.314/32*ln0.377)+1.2*(1.0045*ln(319.45/293.15)-8.314/29*ln0.623) 的值.
    题型：数学计算
    解:
          0.8*(0.909*ln(319.45/363.15)-8.314/32*ln0.377)+1.2*(1.0045*ln(319.45/293.15)-8.314/29*ln0.623)
        =0.8*(0.909*ln0.879664-8.314/32*ln0.377)+1.2*(1.0045*ln(319.45/293.15)-8.314/29*ln0.623)
        =0.8*0.136903+1.2*(1.0045*ln(319.45/293.15)-8.314/29*ln0.623)
        =0.8*0.136903+1.2*(1.0045*ln1.089715-8.314/29*ln0.623)
        =0.8*0.136903+1.2*0.221967
        =0.109522+1.2*0.221967
        =0.109522+0.26636
        =0.375882
    答案:0.8*(0.909*ln(319.45/363.15)-8.314/32*ln0.377)+1.2*(1.0045*ln(319.45/293.15)-8.314/29*ln0.623)=0.375882
