And the influenza symptoms is upper respiratory, on the other contrary, lower respiratory infection are symptom of chronic disease. It is difficult to discover the lower respiratory symptoms through external body examinations; it takes the inspection to recognize diseases. The study mainly focuses on the application technology of (Particle Image Velocimetry，PIV) and dyestuff to the lower respiratory. From the major trachea to other 6 bronchus that we practice the asymmetric model experiment’s study of lower respirator’s flow pattern. To apply the differential pressure transducer to measure the pressure connections between tracheas. The study founds the air flow entrance velocity value is (Re=1201)[23]. By the scientific of flow experiment to reveal the internal asymmetric brannchus relations and causes with disease and tumor.
