Structure Analysis, Forecasting and Urgent Measure for Surprised Severe Weather

OuYang Shoucheng,Xie Na,Hao Liping

Strategic Study of CAE 2005, Volume 7, Issue 9, Pages 9-13

Abstract:

In this paper the structure characteristics of surprised rain gust and storm in Beijing and Shanghai and heavy rain gust in NE Sichuan are analyzed, and the surprised severe weather is discussed by V - 3θchard. The results showed that the surprised weather can be forecast. Facilities for water drainage water storage and windbreak should be allocated.

Engineering doi: 10.1016/j.eng.2023.02.021

Abstract: Biodegradable polylactic acid (PLA) melt-blown nonwovens are attractive candidates to replace non-degradablepolypropylene melt-blown nonwovens.However, it is still an extremely challenging task to prepare PLA melt-blown nonwovens with sufficientThe resultant PLA/PHBV (5 wt% PHBV) melt-blown nonwovens exhibit the highest mechanical properties.The tensile stress, elongation, and toughness of PLA/PHBV (5 wt% PHBV) melt-blown nonwovens reach 2.5
