Cross-shaped High-speed Rail Network in Southwest China
Guizhou was not easily accessible in history, which made its communication with the outside world rather difficult. As what Guo Zizhang, Governor of Guizhou in the late Ming Dynasty, said about the place, Guizhou had the most precipitous mountains and most dangerous rivers. Today, however, Guizhou has a multimodal transportation system that offers air,…

Geophysical remote quantification of seafloor methane hydrates is needed for studies of the impact of global warming on greenhouse gas release into the water column and atmosphere, for geohazard prediction and for economic resource assessment. Both methane hydrate, and especially any associated free methane gas, are known to give rise to acoustic velocities and attenuations that are highly dependent on measurement frequency. However, the exact relationships between these acoustic properties and hydrate content are poorly understood, but are known to be influenced by hydrate and gas bubble morphology, which are influenced in turn by sediment type. Gas “bubbles”, and resultant hydrate morphologies when the sediment is within the gas hydrate stability zone, take on sheet-like, lenticular or nodular forms in fine grained, cohesive sediments (clays and muds), but tend to be finely dispersed and spherical within the pore spaces of coarse grained sediments (sands and gravels) . Previous laboratory studies on methane hydrate-bearing sand showed how seismic frequency (< 500 Hz) velocity and attenuation vary with hydrate content, results useful to marine seismic data interpretation. The aim of this study is to extend those observations to the higher, acoustic frequency range of 1 – 10 kHz, pertinent to high resolution seismic surveys of the seabed and also to sonic borehole logging. Hence, we are developing a novel acoustic pulse tube capable of accepting large sediment core samples (7 cm diameter, < 1 m long) and simulating seafloor gas hydrate formation conditions (temperatures down to 4 ?C, pore pressures in excess of 20 MPa). Crucially, the size of the samples will enable us to measure bulk behavior of centimeter-scale heterogeneities in sediment samples representative of in situ gas a nd hydrate morphologies. A novel electrical resistivity tomography system will aid the characterization of sample heterogeneity and give complementary electrical resistivity information, needed for improving joint acoustic-electrical interpretation schemes. The experimental results on sands and muds will be used to develop acoustical th eory on gas bubble resonance and its application to seafloor hydrate quantification.

SOLIFLEX filter fans and exhaust filters effectively ventilate enclosures and control panels if the ambient temperature is lower than the internal encl osure temperature. Our filter fans come in an attractive plastic housing and are available for both AC and DC voltages.
All dimensions and enclosure cutouts correspond to the market standards. The integrated filter mats inside the filter fan and outlet filter effectively prevent the inside of the enclosure from becoming dirty. Seifert filter fans can be installed without tools, and the filter can also be easily replaced. SOLIFLEX filter fans are also available with reversed air flow…
