| 1 | A facile preparation of a novel nonleaching antimicrobial waterborne polyurethane leather coating functionalized by quaternary phosphonium salt显示文摘The aim of this research is to develop a novel non-leaching antimicrobial waterborne polyurethane(WPU)leather coating material with covalently attached quaternary phosphonium salt(QPS).The structure of the QPS-bearing WPU has been identified,and their thermal stability,mechanical property,and antimicrobial performance have been investigated.The results reveal that the incorporation of QPS slightly reduces the thermal stability of WPU material but would not affects its usability as leather coating.Despite the presence of hydrophobic benzene in QPS structure,the strong hydration of its cationic groups leads to the increased surface contact angle(SCA)and water absorption rate(WAR)of the films,suggesting that the water resistance of the films needs to be improved for the purpose of leather coatings.Antibacterial tests demonstrate that when the QPS content is 20 wt%,QPS-bearing WPU shows effective antimicrobial activity against bacteria.The WPU containing QPS prepared in this study is a non-leaching antimicrobial material and has great potential application as leather coating. | Chunhua Wang Jianhui Wu Li Li Changdao Mu Wei Lin | 2020 | Journal of Leather Science and Engineering2020，2，1： | 2 |

| 10 | A discussion on improving typhoon observation through radar by scanning the negative elevation angle显示文摘Certain feasibilities and features were discussed in typhoon detection by radar with a negative elevation angle according to the relationship between the remote detecting range and the elevation angle of the new generation weather radar, in order to rectify the disadvantages of detecting capability for remote low-level echo with a lowest elevation angle of 0.5° in the common detecting mode. The data obtained from detecting the typhoon of Haitang and Changmi with radar for their negative elevation angles and the observed data for the common lowest elevation angle of 0.5° were compared to each other. The results showed that the detection of remote low level cloud system with radar could be improved by using the negative elevation angle, and the structure and the evolution trend of a typhoon could be better judged. The increasing degree of detection for negative elevation angles in the current volume scanning mode should be helpful for predicting the intensity and developing trend of windstorms, to further improve the capability of warning and nowcasting. The detection of negative elevation angle could also help reveal the development and change of typhoon's low level cloud system. As far as the typhoons of Haitang and Changmi were concerned, the detecting area of Changmi was increased by 1.09 times with the negative elevation angle of 0.31°, compared with the elevation angle of 0.48° if the threshold value for the sea echo within 100 km was eliminated. Several volume scans of Haitang were increased by 2.1%–7.9% for the negative elevation angle of 0.36° compared with the elevation angle of 0.49°. Therefore, the radar detecting capability of typhoons could be improved by the detection of negative elevation angles to some extent. This could make up for the disadvantages of a low detecting capability for remote low-level echo in the common detecting mode. At the same time, a negative elevation angle could be easily influenced by the ground clutter and the close sea wave clutter which interfered with the assessment of the typhoon structure at times. Assessing these advantages and disadvantages, some advantages for using negative elevation angle were discovered from the observation of the typhoons Haitang and Changmi, if the negative elevation angle with radar was selected reasonably in some conditions. As a result, a certain value arose for improving and monitoring the early warning system for typhoons, paying close attention to the detection of negative elevation angles. | BaLin Xu ShaoHui Miao LiPing Liu ChangDao Wu GaiLi Wang | 2014 | Research in Cold and Arid Regions2014，6，6： | 0 |
| 11 | Primary Analysis of Sounding Data from a Multi-channel Parallel Ground-based Microwave Radiometer显示文摘The sounding data of a multi-channel parallel ground-based microwave radiometer( MWR) in Fuzhou station in July and August in 2016 were compared with the sounding data of a radiosonde in the same position in the same period. The results showed that the correlations between the two types of temperature or humidity detected by the microwave radiometer and the radiosonde were significant at 0. 05 level,indicating that the overall changing trends of temperature or humidity detected by the two devices were similar. The temperature detected by the microwave radiometer and the radiosonde decreased with the increase of height. The difference between the changes in the height of the zero layer detected by the microwave radiometer and the radiosonde was not significant,and their trends were basically the same. | Ren Yong Lin Lizheng Wu Changdao | 2018 | Meteorological and Environmental Research2018，9，4： | 0 |
