1. -- Further reforming and perfecting the grain circulation system.

2. An aerated recirculated aquaculture system (10) including a culture tank (12) and an aeration and circulation system (18).

3. In an incorrect vascular access, the flow conditions in the communicating intra- and extracorporeal blood circulation system change.

4. Two layers of sunscreen structure, infrared light board cooling circulation system, laminated heat; open infrared lights, air cooling system to work immediately.

5. Under different pressures the flashing in riser of natural circulation system and its effect on flow stability were studied by the method of visual observation in synchronism with data recording.

6. What is an Anticyclone? An anti-cyclone -- also known as a high pressure area -- is a large atmospheric circulation system with the wind flowing clockwise around it in the Northern Hemisphere, and counter-clockwise in the Southern Hemisphere
