BEIJING, Aug. 13 (Xinhua) — The following is a summary of published science and technology news of China.
SPACE INFORMATION SERVICES
Chinese researchers used remote sensing and model forecast data to help Chinese merchant ships Tian’en and Tianyou safely navigate the Northeast Passage of Arctic this summer.
The researchers from the Aerospace Information Research Institute of the Chinese Academy of Sciences figured out the automatic method of satellite remote sensing data processing, as well as algorithms for deriving sea ice and ocean dynamics parameters.
The researchers provided digital services in seven types of data including wind field, sea ice cover and sea ice concentration for the ships.
Researchers have found that human mobility restrictions could be an effective strategy to contain the spread of COVID-19 in Shenzhen, south China’s Guangdong Province.
The researchers from Shenzhen University have developed a model to quantify the potential effects of intracity mobility restrictions on the spread of COVID-19 and controlling the pandemic.
The application of this model can help city authorities make decisions on optimal COVID-19 control policy. Besides, by balancing the potential damage inflicted by COVID-19 on economic and social costs, society can benefit the most.
SCIENTIFIC EXPEDITION IN THE YANGTZE RIVER
China launched a scientific expedition in the headwater region of the Yangtze River, China’s longest river, on Tuesday, according to the Changjiang River Scientific Research Institute (CRSRI) of the Changjiang Water Resources Commission.
The comprehensive scientific expedition, led by the commission, aims to investigate the ecological and environmental problems in the region, including glacial recession, freeze-thawing erosion and lake expansion, according to the CRSRI.
