Published in 2019 at "Journal of Quantitative Spectroscopy and Radiative Transfer"

DOI: 10.1016/j.jqsrt.2018.11.009

Abstract: Abstract Weighting function can affect the retrieval of the column gas mixing ratio of integrated path differential absorption (IPDA) lidar because it contains the vertical distribution information of the target gas. In order to optimize… read more here.

Published in 2019 at "Geophysical Research Letters"

DOI: 10.1029/2018gl081168

Abstract: Double seismic zones are ubiquitous features of subduction zones, where seismicity is distributed along two layers separated by a region with significantly less seismic activity. Dehydration embrittlement is thought to be responsible for earthquakes in… read more here.

Published in 2021 at "Advances in Civil Engineering"

DOI: 10.1155/2021/2044717

Abstract: When stratified mining is adopted in high-gas and extrathick coal seam, a large amount of pressure-relief gas of the lower layer flows into the upper layer goaf along the cracks in the layer, resulting in… read more here.
