Hydrothermal vent fluids play very important role in the deep-sea geochemistry cycle, and support the extreme biological communities. But, there are very few sensors can be used for the in situ measurement of the chemical compositions of the emerging vent fluids. The extremely high temperature and pressure will kill most of them. The traditional sampling technology cannot maintain the sample temperate...
Objective: Exploring the regular pattern in combination characteristics of tongue, complexion and pulse in Traditional Chinese Medicine (TCM) and further discussing the standardization of syndrome differentiation of Chronic Gastritis. Methods: Based on 919 Chronic Gastritis cases collected, we combined the algorithms of SM spectral clustering with modularity to identifying sign groups for the involved...
A new deep-sea hybrid Raman insertion probe (RiP) has been developed by the Institute of Oceanology, Chinese Academy of Sciences (IOCAS) and the Ocean University of China (OUC) for the detection of the hydrothermal vent, cold seep fluid and sediment pore water geochemistry. The novel probe can work at temperature range from 0 to 450 °C with water depth to 4500 m.
In situ CO2 and CH4 concentrations dissolved in vent-associated seawater (within ten meters from the seafloor) in mid-Okinawa Trough had been measured by novelty CO2 sensor and CH4 sensor based the Remotely Operated Vehicle (ROV) mounted on R/V KEXUE. The results showed that the maximum values of CO2 and CH4 both occur near active hydrothermal vents in Iheya North area. The maximum detection concentration...
In this paper, we will report the first scientific using results for a remotely operated vehicle (ROV) named Fa Xian at R/V Ke Xue. A deep-sea hydrothermal area nearby Iheya North at Okinawa Trough and a cold seep area nearby Taiwan had been visited by ROV Fa Xian at the spring of 2014. An Insite Zeus Plus HD color zoon camera had collected a series of high definition video in both of areas. In situ...
A supercritical CO2 (SC- CO2) dyeing equipment together with computer control system is designed, and the structure analysis function of ANSYS software is used to analyzed static stress of master parts and multiphase flow of the equipment in order to confirm the concentration area of all kinds of component stress. The model is built, by which the velocity vector distribution chart and pressure distribution...
There is a new way, using FLUENT--a computational fluid dynamics software, to analyze the inside flow field of hydraulic retarder instead of using one-dimension flow theory. In the simulation process, the inside flow field is assumed whole fluid-filled. And the moving areas use sliding mesh model while the turbulence model chooses standard two equations model. Finally, there are analysis of the pressure,...
