4*X1 -7.9541*X2+1/2*X3+ 2*X4+ 1*X5+3*X6+ 5*X6+1/2*X7=0
4*X1+2*X2-7.9541*X3+ 2*X4+2*X5+ 4*X6+6*X6+1*X7=0
3*X1+1/2*X2+1/2*X3-7.9541*X4+1/2*X5+2*X6+1/2*X6+1/2*X7=0
3*X1+1*X2+ 1/2*X3+2*X4-7.9541*X5+2*X6+1*X6+1/3*X7=0
1/2*X1+1/3*X2+ 1/4*X3+1/2*X4+ 1/2*X5-7.9541*X5+1/2*X6+1/4*X7=0
1/4*X1+1/5*X2+1/6*X3+ 2*X4+1*X5+2*X5-7.9541*X6+1/2*X7=0
3*X1+2*X2+1*X3+ 2*X4+3*X5+ 4*X5+2*X6 -7.9541*X7=0
其中 X1+X2+X3+X4 +X5+X6+X7+X8=1
