求解Mathematica（Wolfram）中的非线性方程系统

Question

我正在尝试通过NSOLVE的功能求解Mathmatica中的方程系统，

代码应代表工厂的质量平衡，在一个试图更改Conc的流中。溶剂及其可行的溶剂指向有效的

代码是：

NSolve[{
  m1 == m4 + m5,
  m1*0.952 == m4 + m5*0.454,
  m1*0.048 == m5*0.546,
  x6MgCl2 + x6H2O == 1,
  0.255*x6MgCl2 == x6Mg,
  0.745*x6MgCl2 == x6Cl2,
  x11H2O + x11Br2 + x11Cl2 == 1,
  m5 + m7 + m9 + m10 + m12 == m6 + m11,
  m5*0.072 == m6*x6Mg,
  m5*0.454 + m7 + m10 == m6*x6H2O + m11*x11H2O,
  m5*0.474 == m11*x11Br2,
  m9 + m12 == m6*x6Cl2 + m11*x11Cl2,
  m6 == m7 + m8,
  m6*x6MgCl2 == m8*0.056,
  m6*x6H2O == m7 + m8*0.944,
  m11 == m12 + m13 + 8163.265,
  m11*x11Br2 == m13*0.030 + 8000,
  m11*x11H2O == m13*0.970 + 163.265,
  m11*x11Cl2 == m12,
  x11Cl2 == x11Br2*0.0311,
  m1 >= 0, m4 >= 0, m5 >= 0, m6 >= 0, m7 >= 0, m8 >= 0, m9 >= 0, 
  m10 >= 0, m11 >= 0, m12 >= 0, m13 >= 0, x11H2O >= 0, x11Br2 >= 0, 
  x11Cl2 >= 0, x6MgCl2 > 0, x6H2O > 0, x6Mg > 0, x6Cl2 > 0
  }, {m1, m4, m5, m6, m7, m8, m9, m10, m11, m12, m13, x11H2O, x11Br2, 
  x11Cl2, x6MgCl2, x6H2O, x6Mg, x6Cl2}, Reals]

我得到的答案是：

{{m1 -> 192590., m4 -> 175660., m5 -> 16931., m6 -> 2.0519*10^5, 
  m7 -> 119830., m8 -> 85365., m9 -> 3561.4, m10 -> 73874., 
  m11 -> 9251.3, m12 -> 249.58, m13 -> 838.41, x11H2O -> 0.10556, 
  x11Br2 -> 0.86747, x11Cl2 -> 0.026978, x6MgCl2 -> 0.023297, 
  x6H2O -> 0.9767, x6Mg -> 0.0059407, x6Cl2 -> 0.017356}}

但是，如果我更改eq 14＆amp; 15为了减少浓度。我没有得到答案（如果我做oppsite，我确实会得到答案）

： 更改架子为：

m6*x6MgCl2 == m8*0.05,
m6*x6H2O == m7 + m8*0.95,

不要给我一个答案，将其更改

m6*x6MgCl2 == m8*0.06,
m6*x6H2O == m7 + m8*0.94,

为答案，

我需要所有的值才能为正，所有x代表质量分数，需要在0到1之间，

请帮助我解决这个问题:(
