Using Remote Sensing to Monitor Aquatic Vegetation and Algal Blooms in Lakes in Yellow River Basin

Autor: CHEN Yonggui, ZHU Yuxiang

Publikováno v: Guan'gai paishui xuebao, Vol 41, Iss 12, Pp 81-88 (2022)

【Background and objective】 Global warming and anthropogenic activities will change ecological functions of lakes, resulting in eutrophication and algal blooms, for example. Monitoring the change in aquatic vegetation and algae is important to imp

Stress Calculations Adopted Finite Element Method of Pressure Steam Pipeline Containing Defects

Autor: Chen Yonggui, Tang Ping, Zhong Jiang, Yan Sunting, Jin Nanhui, Liu Lintao

Publikováno v: MATEC Web of Conferences, Vol 353, p 01003 (2021)

The stress behavior of defects is the key factor in the safety assessment of pressure steam pipeline containing defects. For achieving carbon peaking and carbon neutrality, high-parameter pressure steam pipelines are widely designed in the recent yea
