1八乙墓卟啉和四苯基卟啉合钌(Ⅱ)及锇(Ⅱ)的二氧加合物的红外光谱显示文摘OEP(八乙基卟啉阴离子)和TPP(四苯基卟啉阴离子)合钌(Ⅱ)和锇(Ⅱ)的二氧加合物由matrix分离技术得到(T=20-43K,P=10-5-10-6torr).为了确定v(O2)带的归属应用了同位素取代法16O2/18O2.IR谱说明对于钌的两种加合物(指OEP和TPP)都有两种异构体,其V(16O2)频率为:Ru(OEP)O2,1141和1103cm-1;Ru(TPP)O2,1167和1114cm-1.Os(TPP)O2只生成一种异构体,v(16O2)=1090cm-1,异构体v(16O2):[Ru(OEP)O2],1141cm-1,[Ru(TPP)O2],1167cm-1,这些加合物约在100K时分解,它们的结构指定为endon,而异构体[Ru(OEP)O2],1103cm-1,[Ru(TPP)O2],1114cm-1和[Os(TPP)O2],1090cm-1,在240—270K分解,它们的结构指定为桥联二聚体.在加合物中,将OEP换成TPP引起的钌加合物v(O2)频率的改变比铁和钴加合物更大.v(O2)相对强度的变化顺序为:Fe(Ⅱ)→Ru(Ⅱ)→Os(Ⅱ).Lewandowski, W.(Institute of General Chemistry. warsaw Agricultural University.SGGW. 02-528 Warsaw, Rakowiecka 26/30, Poland)(Matrix isolation IR spectra were obtained during author’s stay at the Marquette University, Milwaukee, WI 53233(USA). 1994无机化学学报1994,10,1:4
2Global Wheat Head Detection 2021:An Improved Dataset for Benchmarking Wheat Head Detection Methods显示文摘The Global Wheat Head Detection(GWHD)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/institutions.With an associated competition hosted in Kaggle,GWHD_2020 has successfully attracted attention from both the computer vision and agricultural science communities.From this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label reliability.To address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat heads.We now release in 2021 a new version of the Global Wheat Head Detection dataset,which is bigger,more diverse,and less noisy than the GWHD_2020 version.Etienne David Mario Serouart Daniel Smith Simon Madec Kaaviya Velumani Shouyang Liu Xu Wang Francisco Pinto Shahameh Shafiee Izzat SATahir Hisashi Tsujimoto Shuhei Nasuda Bangyou Zheng Norbert Kirchgessner Helge Aasen Andreas Hund Pouria Sadhegi-Tehran Koichi Nagasawa Goro Ishikawa Sébastien Dandrifosse Alexis Carlier Benjamin Dumont Benoit Mercatoris Byron Evers Ken Kuroki Haozhou Wang Masanori Ishii Minhajul ABadhon Curtis Pozniak David Shaner LeBauer Morten Lillemo Jesse Poland Scott Chapman Benoit de Solan Frédéric Baret Ian Stavness Wei Guo 2021Plant Phenomics2021,3,1:2
