Submarine temperature, pressure, gas compositions, geothermal gradient and syngenetic water salinity control the depth of hydrate zone basement.Autochthonous bacteriogenic mod...
The experiment of a combined process of"biological contact oxidation and micro-filtration(MF) membrane" was conducted for the advanced treatment of aquicultural product processing wastewater.
But the compatibility between nano-meter particles and PVC is not very good in nano-meter scale.Therefore the toughening modification mechanism is studied more thoro...
The sapropel-type organic matter evolution need higher temperature and biger depth and its main gas generating zone is deeper than humic-type organic matter's.
Depth and particle size were primary and secondary environment variables that influence the community structure of brachyuran crabs in the present geographic region.
Results The difference values calculated were various with the arch form, the sequence was oval, round, parabola, catenuliform, and hyperbola from big difference to smell.
