然后，多个这种滤筒可彼此嵌套并且被合适的排气流引导挡板分开，以形成颗粒过滤器组件。

A plurality of such cartridges can then be nested within each other and separated by appropriate exhaust gas flow directing baffles to form a particulate filter assembly.

典型的四喷管火箭底部挡板采用涡轮废气排气方案能大大减少底部热流，这是脉冲式风洞的成功应用成果；

For a rocket with typical four-nozzles , using turbine exhaust scheme could greatly reduce the heat flux on the base plate. This is a successful example of impulse wind tunnel application.
