针对设施番茄长季节栽培过程中,因植株管理不当等造成的植株易早衰、产量和品质下降等问题,以圣罗兰3689为试材,以不换头为对照(CK),设置每4穗果(T1)、6穗果(T2)、8穗果(T3)进行换头一次的3个处理,研究不同换头节次对番茄生长、开花坐果时间和产量的影响。结果表明,随生育期延长,所有处理的番茄株高和茎粗均呈增加趋势,侧枝叶片光合色素含量和净光合速率均呈先升高后降低趋势。与CK相比,T1、T2、T3处理的茎秆长度和产量均有所增加,并在一定程度上延长了番茄采收期;其中,定植后240 d,T1处理的株高、茎粗和产量分别增加8.7%、3.8%和7.1%;T1处理前4穗果的转色时间和采收时间分别提前9、22、29、10 d和12、28、15、9 d,第14穗果采收时间延长了19 d,经济效益以T1处理较好。综上所述,每4穗果换头1次,有利于长季节栽培番茄生长和产量形成,能部分缓解春节和暑期番茄产品的供给,可作为番茄长季节优质高产栽培的植株调整方式。

Discovery of Balmer broad absorption lines in the quasar LBQS 1206+1052

引用

Research in Astronomy and Astrophysics 2012年第4期12卷 369-382页

作者： tuo ji Ting-Gui Wang Hong-Yan Zhou Hui-Yuan Wang Key Laboratory for Research in Galaxies and Cosmology University of Science and Technology of China （USTC） Hefei 230026 China Center for Astrophysics USTC Hefei 230026 China Polar Research Institute of China Shanghai 200136 China

We report the discovery of Balmer broad absorption lines （BALs） in the quasar LBQS 1206＋1052 and present a detailed analysis of the peculiar absorption line spectrum. Besides the Mg II λλ2796, 2803 doublet, BALs are also detected in the He I＊ multiplet at λλ2946, 3189, 3889 A arising from the metastable helium 2 3 S level, and in Hα and Hβ from the excited hydrogen H I＊ n = 2 level, which are rarely seen in quasar spectra. We identify two components in the BAL troughs of v ～ 2000 km s 1 width： One component shows an identical profile in H I＊, He I＊ and Mg II with its centroid blueshifted by v c ≈ 726 km s-1 . The other component is detected in He I＊ and Mg II with v c ≈ 1412 km s-1 . We estimate the column densities of H I＊, He I＊, and Mg II, and compare them with possible level population mechanisms. Our results favor the scenario that the Balmer BALs originate in a partially ionized region with a column density of N H ～ 10 21 10 22 cm-2 for an electron density of n e ～ 10 6 10 8 cm-3 via Lyα resonant scattering pumping. The harsh conditions needed may help to explain the rarity of Balmer absorption line systems in quasar spectra. With an i-band PSF magnitude of 16.50, LBQS 1206＋1052 is the brightest Balmer-BAL quasar ever reported. Its high brightness and unique spectral properties make LBQS 1206＋1052 a promising candidate for followup high-resolution spectroscopy, multi-band observations, and long-term monitoring.

Pattern design on 3D triangular garment surfaces

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第10期8卷 1642-1649页

作者： WANG jin LU Guo-dong LI ji-tuo CHEN Long ZHANG Dong-liang State Key Lab. of CAD ＆ CG Zhejiang University Hangzhou 310027 China Institute of Automation Chinese Academy of Sciences Beijing 100080 China Digital Fashion Ltd. Osaka 5410053 Japan

This paper focuses on a pattern design method for a 3D triangular garment surface. Firstly, some definitions of 3D style lines are proposed for designing the boundaries of patterns as drawing straight lines or splines on the triangular surface. Additionally some commonly used style lines are automatically generated to enhance design efficiency. Secondly, after style lines are preprocessed, a searching method is presented for quickly obtaining the boundaries and patches of a pattern on the 3D trian- gular surface. Finally a new pattern design reuse method is introduced by encoding/decoding the style line information. After style lines are encoded, the pattern design information can be saved in a pattern template and when decoding this template on a new garment surface, it automates the pattern generation for made-to-measure apparel products.
