This paper briefly introduces the basic fact of the existence of the PaleoTethys Ocean in the Lungmu Co-Shuanghu suture, i.e. the ages and natures of Early Paleozoic ophiolites, Permian ophiolites, Devonian-Permian radiolarian cherts, accretionary slabs of different natures, two types of tectonic mrlange zones and covers of ophiolites. The starting time of the Paleo-Tethys Ocean in Qiangtang may be traced back to Early Paleozoic and the records about the oceanic basin evolution persisted from the Late Devonian to Late Triassic.

A measuring approach of pressure oscillation has been developed and experiments are conducted in a 10 liter two-dimension air-lift loop reactor. The experimental results show that the local mass transfer parameters have close relationship with the operating conditions, the structure of ALR and the properties of the reaction systems. A series of measurements of pressure pulse indicate that a gas distribution zone exists near the gas sparger, and in this zone the responding signals of pressure pulse are different with the signals measured in other parts of the reactor.
