| 2 | Resistance Identification of Different Flue-cured Tobacco Varieties against Black Shank显示文摘The resistance of 15 flue-cured tobacco varieties were identified by artificial inoculation of black shank. The results showed that K326,Yunyan 202 and NC102 belonged to resistance variety against black shank,and the resistance successively were K326 > Yunyan 202 > NC102; Yunyan 87,Cuibi 5,Yunyan 85,Yunyan 97 and Cuibi 7 belonged to moderate resistance variety against black shank,and the resistance successively were Yunyan 87 > Cuibi 5 > Yunyan 85 >Yunyan 97 > Cuibi 7; Cuibi 12,NC82,PVH06 and Cuibi 14 belonged to moderate susceptible variety against black shank,and the resistance successively were Cuibi 12 > NC82 > PVH06 > Cuibi 14; Cuibi 1 and Hongda belonged to high susceptible variety against black shank,and the resistance successively were Cuibi1 > 09011 > Hongda. The disease dynamics of flue-cured tobacco varieties were positively correlated with variety susceptibility,namely the earlier infection in susceptible variety,the faster the disease progression. | Peng Shicheng Yang Peng Zheng Li Cai Hengbin Guan Yu | 2015 | Plant Diseases and Pests2015，6，4： | 1 |
| 3 | Dual-band dynamic reconfigurable intelligent surface for signal enhancement in millimeter wave显示文摘Millimeter wave with large bandwidth,high transmission rate,and low delay is considered a reliable alternative to cope with the spectrum shortage.However,the fast attenuation and narrow beam characteristics make it difficult to achieve long-distance or wide-range applications.Here,a 1-bit dual-band reflective reconfigurable intelligent surface(RIS)for signal enhancement in millimeter wave with 16×16 elements is designed,fabricated,and measured.Different from most existent RIS,dynamic programming is realized at two separate frequency bands by integrating the PIN diodes and field-programmable gate array(FPGA).Particularly,the beam deflection,dual-beam,and multi-beam are created based on the coding theory and convolution operation,proving the effectiveness of wavefront manipulation.Moreover,the far-field patterns and signal power with different coding sequences are measured and compared.It is indicated that the received signal power is 6–7 dB stronger than that without coding,which shows good agreement with the desired expectations.The proposed reconfigurable metasurface exhibits great potential in beam forming,making it a promising candidate for progressive wireless communication applications. | YAO HuiMing DU XinRun WANG HengBin GAO Song PANG YaChen ZHENG HaiRong GONG HuiWen LI Yi XU JianChun ZHANG JianHua BI Ke | 2024 | Science China(Technological Sciences)2024，67，4： | 0 |
