SMR助记

Compared with deterministic optimization design results, uncertainty optimization design results are more reliable and more robust. The uncertainty optimization design method can provide better means for system concept design of SMR.

与确定性优化设计结果相比，不确定性优化设计结果更可靠、更稳健，为固体火箭发动机总体方案设计提供了更好的方法和手段。

Finally, finite element and dynamic substructure method for VFD model are applied to dynamic response calculation of SMR. Power spectrum density of SMR grain response is obtained under random excitation of trapezium acceleration power spectrum density.

将VFD模型有限元法和模态综合法用于发动机响应计算，得到了梯形谱随机激振作用下发动机药柱响应的功率谱密度，它集中在一个窄带频域内，形成共振尖峰。

Additionally, the paper discusses some phenomena and problems of the urban form, in the process of the Old Town improvement and the new port district planning in the Chinese zone, in a manner to imitate the development model of the SMR zone.

对中国区在仿照附属地模式进行的旧城改造和新区规划建设中，存在的城市形态现象和问题进行了讨论。
