Csamt Phase Correction And Its Application In Detection Of Water-Accumulating Area Of Goaf In Coal Mine, Su Chao, Hou Yanwei, Wang Cheng, Li Dan

Coal Geology & Exploration

Magnetic field data of controlled source audio magnetotelluric method(CSAMT) is vulnerable to electromagnetic interference, and will lead to serious degradation of phase data quality. The affected phase data are corrected by referring to the high quality phase data of adjacent measuring points and combining the least squares fitting and interpolation method. Through forward simulation analysis, it is found that cubic polynomial interpolation is effective, not only can restore the variation characteristics of phase curve more accurately, but also involve the corrected phase data in the inversion calculation, so that the inversion results are more accurate and reliable.

IGC Proceedings (1977-2023)

There is uncertainty about future climatic predictions; however there is little doubt amongst experts that the future will be warmer. Climate change and the associated elevation in atmospheric CO2 level and temperatures will provide novel challenges and potential opportunities for cultivated plant species. Plant breeding and domestication can contributed to improvements in both yield and quality of grasses and fodder shrubs. A range of key functional traits is required to cope with this changing climate. The main challenges that are discussed are new pests and pathogens; changes in the pattern of nutrient supply and forage quality; challenge associated with …

IGC Proceedings (1977-2023)

In integrated systems it is common to use the no-tillage method. The adoption of this method improves the system's sustainability (Laurent et al. 2011). It is necessary to understand the effects of the integrated systems on sward structure and its consequences in the grazing process and in animal production. The intake rate of grazing animals is primarily responsible for the animal performance (Coleman 2006), which short-termdepends mainly on sward structure (Laca and Demment 2006). The sward height has great influence on the animal decision on where to take the next bite (Mcgilloway et al. 1999). The hypothesis of …
