侦察敌方目标

Can be a long time in the vicinity of the enemy's territorial waters or on the high seas cruising and roaming, and the enemy coast, combat ships and other targets in the sea and electronic surveillance: Receive and record enemy radio communications, radar and weapons control systems, electromagnetic waves emitted signal, these electronic devices to identify the tactical and technical performance; the identification of radio, radar and sonar station location and distribution system, identify the relationship between its command ; listening phones, intercepted and deciphered wireless telegraphy; tracking and monitoring ships and other marine activities.

能够长时间地在敌方领海附近或公海上游弋和漂泊，对敌沿海地区、作战海域和舰船等目标实施电子侦察：接收并记录敌方无线电通信、雷达和武器控制系统等发出的电磁波信号，查明这些电子设备的战术技术性能；查明无线电台、雷达站和声纳站的位置和配系，判明其指挥关系；侦听无线电话，截获并破译无线电报；跟踪监视海上活动的舰船等。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
