To reveal aft end internal flow feature of a solid rocket motor with submerged nozzle, a two dimension cold flow test model with rectangular channel was designed The cold gas simulation was based on geometric similarity and aerodynamic analogy Mean and fluctuating velocity field was measured using phase doppler particle analyzer It showed that the flow separates at upstream of the submerged nozzle and reattaches on the tip of the nozzle nose A relatively steady recirculation zone formed in...

为了揭示含潜入喷管的固体火箭发动机尾部流动特征，按照几何相近和气动相似原则设计了通道为矩形的二维冷流实验模型，利用相位多普勒粒子分析仪对燃烧室尾部气流的时均速度和湍流脉动速度进行了测量。实验结果表明气流在潜入喷管入口上游发生分离，再附点位于喷管前端部外侧，背壁空腔内形成一个较为稳定的回流区，流场的轴向和横向湍流强度都比较大

Under the influence of geography, plant,building and moving objects, electromagnetic wave will reflect, diffract, scatter, andcause signal multipath time delay and Doppler frequency spread, make the quality ofcommunication bad.

Tei指数是一种简单可靠的定量综合评价子痫前期胎儿心肌受累的指标。

To confirm the hypothesis that the pathogenic mechanism of air infusion in the circulatory system is not bubble blockade of blood vessels but the consequence of anoxia of the vital organs,different amounts of air were injected into the great sapenous vein of 22 dogs,and then heart rate,cardiac rhythm and bubble sound were monitored with a Doppler probe at the precordial region.

为探讨循环系统内注入空气致病机理，向22只狗大隐静脉内注入不等量空气并在心前区用Doppler监测心率、心律和气泡音。结果发现，维持心前区Ⅳ级气泡音的17只狗，依次出现呼吸和心率加快、心律紊乱、心率缓慢、腹式呼吸加强，其中12只狗继续缓慢注入空气至呼吸停止，任选10只狗胸外按压，8只狗复苏后行为无异常，2只狗未能复活。另2只狗呼吸停止后立即尸检，可见右心房、室、腔静脉和肺血管中有大量气泡。
