针对此问题，建立了考虑机群出力约束的机组组合模型，将问题转化为两层多下级无关联的主从递阶单目标决策问题。
The model is translated into a two level single object decision making problem with leader follower strategy with no relation between lower levels.
我们的方法是将简称生成问题转化为等价的序列标注问题，并利用一阶条件随机场建立自动生成模型。
In our method, we transformed the problem into an equivalent sequence tagging problem, and built up the automatic generation model through the first order conditional random field.
为简化双重抗侧力体系二阶分析，将结构的二阶效应转化为结构的负刚度，从而建立分析模型。
A model for simplified second order analysis of the double resistance to lateral force system is built on the basis to transform second order effect into negative stiffness.
这种方法首先把一个一致稳定的系统转化成一个内部平衡系统，然后选择一个内部优势子系统作为降阶模型，该子系统可保留原系统的强可控可观部分，并有一定的稳定性。
Then an internal superior sub-system is selected as the reduced model which retains the strong controllable as well as observable parts of the system and has certain stability.
