优级

The optimal multiuser detection has the exponential complexity, so it cannot be used in practical applications.

最优多用户检测具有指数级的计算复杂度，不能实际应用。

For one-dimension optimization problem, stage pressure ratio and flow angles at the stator trailing edges, solidities at the stator and rotor trailing edges are considered as design parameters, To demonstrate feasibility of the present method, a multiobjective optimization of a six-stage compressor design was performed for maximization of the overall isentropic efficiency and the total pressure ratio, It obtained dozens of reasonable and uniformly distributed Pareto-optimal solutions that outperformed the baseline design in both objectives.

对于一维优化问题，以某六级高压压气机为对象，选取各级的级压比和静子出口气流角以及转子、静子的稠度为变量，得到了几十个在两个目标上均优于初始设计的Pareto最优解。

The method firstly determined the pinch point and the minimum utility targets of the batch processes by the water cascade analysis technology, then synthesized the water network by using the diagram and rules, and then determined the number and volume of storage tanks for batch processes with storage tanks,and lastly described the synthesized optimum water network by the time-water network diagram.The influence of the water network by the flowrate demand of a water-using process was also discussed.

它首先通过水级联分析技术确定间歇过程用水网络的夹点及最小公用工程，然后利用时间-纯度图和设计规则来合成用水网络，对有储罐的情况，确定了储罐的数量与容量，最后利用时间-水网络图描述了所合成的最优间歇过程用水网络，并探讨了用水过程流量对网络的影响。
