由于决定方程组是超定的、线性的或非线性的偏微分方程组，完全求解它们非常困难。
Because the determining systems are a linear or nonlinear overdetermined PDEs, it is very hard to solve them completely.
只有在极特殊的情况下超定方程组才有精确解，一般情况下都是求超定方程组在某种意义下的近似解。
Only in under very special circumstance, an overdetermined systems have accurate solutions and general an approximated solution is often found in some determination of the overdetermined system.
另一类变量与向量函数呈非线性关系。 对于后一类变量，用弃舍随机方法先给出位置初值，然后将问题化为线性最小二乘问题，直接解超定方程组。
The overdetermined equations can be solved directly by using the rejection method to give the initial value of the position first and then converting the problem into a linear—square one.
