1Rainfall Microphysical Properties of Landfalling Typhoon Yagi(201814)Based on the Observations of Micro Rain Radar and Cloud Radar in Shandong,China显示文摘The development and evolution of precipitation microphysical parameters and the vertical structure characteristics associated with Typhoon Yagi(201814)are analyzed in the city of Jinan,Shandong Province based primarily on the observations of a micro rain radar(MRR),a cloud radar,and a disdrometer.The precipitation process is further subdivided into four types:convective,stratiform,mixed,and light precipitation according to the ground disdrometer data,which is in agreement with the vertical profile of the radar reflectivity detected by the MRR.Vertical winds may be the main source of MRR retrieval error during convective precipitation.Convective precipitation has the shortest duration but makes the largest contribution to the cumulative precipitation.Collision-coalescence is the main microphysical process of stratiform precipitation and light precipitation below the bright band observed by the MRR.It is worth noting that as Typhoon Yagi(201814)transformed into an extratropical cyclone,its raindrop size distributions no longer had the characteristics of maritime precipitation,but become more typical of the characteristic of continental precipitation,which represents a very different raindrop size distribution from that which is normally observed in a landfalling typhoon.Hong WANG Wenqing WANG Jun WANG Dianli GONG Dianguo ZHANG Ling ZHANG Qiuchen ZHANG 2021Advances in Atmospheric Sciences2021,38,6:6
2Impact Localization of CFRP Structure Based on FBG Sensor Network显示文摘Low energy impact can induce invisible damage of carbon fiber reinforced polymer(CFRP).The damage can seriously affect the safety of the CFRP structure.Therefore,damage detection is crucial to the CFRP structure.Impact location information is the premise of damage detection.Hence,impact localization is the primary issue.In this paper,an impact localization system,based on the fiber Bragg grating(FBG)sensor network,is proposed for impact detection and localization.For the completed impact signal,the FBG sensor and narrow-band laser demodulation technology are applied.Wavelet packet decomposition is introduced to extract available frequency band signals and attenuate noise.According to the energy of the available frequency band signal,an impact localization model,based on the extreme learning machine(ELM),is established with the faster training speed and less parameters.The above system is verified on the 500 mm×500 mm×2 mm CFRP plate.The maximum localization error and the minimum localization error are 30.4 mm and 6.7 mm,respectively.The average localization error is 14.7 mm,and training time is 0.7 s.Compared with the other machine learning methods,the localization system,proposed in this paper,has higher accuracy and faster training speed.This paper provides a practical system for impact localization of the CFRP structure.Yaozhang SAI Xiuxia ZHAO Lili WANG Dianli HOU 2020Photonic Sensors2020,10,1:2

5Gene cloning and sequence analysis of the cold-adapted chaperones DnaK and DnaJ from deep-sea psychrotrophic bacterium Pseudoalteromonas sp. SM9913显示文摘Pseudoalteromonas sp.SM9913 is a phychrotrophic bacterium isolated from the deep-sea sediment.The genes encoding chaperones DnaJ and DnaK of P.sp.SM9913 were cloned by normal PCR and TAIL-PCR(GenBank accession Nos DQ640312,DQ504163).The chaperones DnaJ and DnaK from the strain SM9913 contain such conserved domains as those of many other bacteria,and show some cold-adapted characteristics in their structures when compared with those from psychro-,meso-and themophilic bacteria.It is indicated that chaperones DnaJ and DnaK of P.sp.SM9913 may be adapted to low temperature in deep-sea and function well in assisting folding,assembling and translocation of proteins at low temperature.This research lays a foundation for the further study on the cold-adapted mechanism of chaperones DnaJ and DnaK of cold-adapted microorganisms.ZHAO Dianli CHEN Xiulan HE Hailun SHI Mei ZHANG Yuzhong 2007Acta Oceanologica Sinica2007,26,6:1

8Thirty Years' Reform and Development in China's Refractories Industry显示文摘1 Development of Refractories Industry Since the People's Republic of China FoundedRefractories is mainly used in high temperature industries,such as metallurgy,building materials,nonferrous,chemical,mechanical,electric power industries,which is the important fundamental material for high temperature industries.China began to manufacture refractories and had it firstly applied in ceramics industry in Shang Dynasty lasting more than 3 000 years. However,China's refractories industry was in a backward state. The total refractories output of China was only 74 thousand tons in 1949. The refractories for metallurgy industry,even for common boiler,needed to be imported.XU Dianli CHEN Jianxiong 2009China's Refractories2009,18,2:1

13Macro-and Micro-physical Characteristics of Different Parts of Mixed Convective-stratiform Clouds and Differences in Their Responses to Seeding显示文摘This study investigates the cloud macro-and micro-physical characteristics in the convective and stratiform regions and their different responses to the seeding for mixed convective-stratiform clouds that occurred in Shandong province on 21 May 2018,based on the observations from the aircraft,the Suomi National Polar-Orbiting Partnership(NPP)satellite,and the high-resolution Himawari-8(H8)satellite.The aircraft observations show that convection was deeper and radar echoes were significantly enhanced with higher tops in response to seeding in the convective region.This is linked with the conversion of supercooled liquid droplets to ice crystals with released latent heat,resulting in strengthened updrafts,enhanced radar echoes,higher cloud tops,and more and larger precipitation particles.In contrast,in the stratiform cloud region,after the Silver Iodide(AgI)seeding,the radar echoes become significantly weaker at heights close to the seeding layer,with the echo tops lowered by 1.4–1.7 km.In addition,a hollow structure appears at the height of 6.2–7.8 km with a depth of about 1.6 km and a diameter of about 5.5 km,and features such as icing seeding tracks appear.These suggest that the transformation between droplets and ice particles was accelerated by the seeding in the stratiform part.The NPP and H8 satellites also show that convective activity was stronger in the convective region after seeding;while in the stratiform region,a cloud seeding track with a width of 1–3 km appears 10 km downstream of the seeding layer 15 minutes after the AgI seeding,which moves along the wind direction as width increases.Dejun LI Chuanfeng ZHAO Peiren LI Cao Liu Dianli GONG Siyao LIU Zhengteng YUAN Yingying CHEN 2022Advances in Atmospheric Sciences2022,39,12:0
