1·If adjustment parameters are in equality constraint, generalized inversion method will be adopted.
平差参数间存在等式约束的情形下，一般采用广义逆法。
2·This actual problem is considered as a nonlinear optimal problem with equality and inequality constraint.
把这个实际问题，归结为含有等式与不等式约束的非线性优化问题。
3·Presented the constraint force control method can be used to the dynamical systems control with the equality constraints.
提出的约束力控制法，可应用于具有任意等式约束的动力学系统的控制问题中。
4·In fact, any numerical discretization method has truncation error and there's no need to treat the difference equations as equality constraint.
事实上，由于任何数值离散方法均存在截断误差，将其作为等式约束是没有必要的。
