The basic problem here is that everyone forgot that an unconstrainedsystem has flexible modes AND the rigid body modes.
这里的根本问题是，人人都忘记了一个无约束系统具有弹性体模态以及刚体模态。

Based on successive unconstrained programming methods, the successive bound constrained programming algorithms for large-scale process system optimization are studied in this paper.
基于非线性约束极小化的序列无约束方法，对大规模过程系统稳态优化的序列界约束方法进行了研究。
