20925 融合降级服务(DS)技术的弹性光网络无疑为降低业务阻塞率，提高用户体验质量(QoE)提供了新方向。 A new direction for the blocking rate reduction and the Quality of Experience (QoE) assurance is provided to the Elastic Optical Network (EON) integrated by Degraded Service (DS) technology.
20926 该文首先针对频谱资源的低效利用和DS导致的业务收益下降问题，建立以最小化频谱消耗和最小化DS等级、频次为联合优化目标的RSA问题的混合整数线性规划模型。 Due to the inefficiency of spectrum resources and the revenue decline causedby DS, a Mixed Integer Linear Programming (MILP) model is proposed with a joint objective that minimizes both spectrum consumption and the priorities and DS frequency of online services.
20927 随后，提出一种基于区分DS和自适应调制的动态RSA算法。该算法考虑业务等级的差异化，并整合自适应调制和DS技术。 A dynamic RSA algorithmbased on differentiated DS and adaptive modulation is proposed, which considers service-priority differentiation,the adaptive modulation and DS technology.
20928 同时，设计区分业务等级的DS损失函数及DS窗口选择策略，为即将受阻业务分配理想的频谱位置和资源。 Meanwhile, DS loss function and DS window selection strategy are designed to differentiate service levels, and ideal spectrum location and resource are assigned for the impending blocked services.
20929 此外，设计考虑频谱与收益均衡关系的网络收益函数，达到频谱资源高效利用，减少降级影响，提升网络收益的目的。 The network revenue function considering the relationship between spectrum and revenue balance is designed to achieve efficient utilization of spectrum resources, reduce the impact of degradation, and enhance network revenue.
20930 最后，仿真验证了所提算法在业务阻塞率和网络收益等方面的优势。 The simulation results verify the advantages of the proposed algorithm in terms ofblocking rate, network profit, etc.
20931 针对多约束稀布矩形阵列天线的优化设计问题，该文提出一种新的矩阵映射(NMM)方法。 A Novel Matrix Mapping (NMM) method is proposed for the synthesis of sparse rectangular arrayswith multiple constraints.
20932 首先，综合考虑阵元的可分布范围与可分布数量，重新定义阵元坐标矩阵的维数以提高阵元分布的自由度。 Firstly, the sizes of element coordinate matrices are resized to improve the Degree OfFreedom (DOF) of elements by taking account of both placeable number and distributable range of elements.
20933 其次，当坐标矩阵定义的阵元数量大于实际阵元数量时，建立选择矩阵以确定各阵元的取舍。 Then, a selection matrix is established to determine which elements should be turned off when the coordinate matrices should be thinned.
20934 再次，针对现有矩阵映射方法无法完全避免不可行解的问题，构建了一种NMM方法，通过两种不同的矩阵映射函数将多约束优化问题转换为无约束优化问题。 By establishing two different mapping functions, a NMM method is presented to overcome the drawbacks of existing methods in terms of flexibility and effectiveness.
