将这句话 Chinese researchers have been most active in solid-phase transport exploitation due to their focus on the NGH hydrate reservoirs in the South China Sea which are characterized by shallow burial

Chinese scientists have shown a strong interest in solid-phase transportation utilization, primarily driven by their emphasis on the NGH hydrate reserves located in the South China Sea. These reserves are uniquely characterized by their shallow burial, absence of dense cover, non-rock stratum, and ease of fracturing.
