| 1 | Cluster Analysis of Polyphenols and Organic Acids in 11 Different Brand Cigarette Samples at Home and Abroad显示文摘The objective of this research was to investigate the differences between local cigarette and foreign cigarette and supplied a base for improving the quality of cigarette. Different kinds of polyphenols and organic acids in 11 different brand cigarette samples at home and abroad were classified by the method of cluster analysis. The results indicated that the 11 samples could be classified into 2 classes. Suyan, Furongwang, Chinese, Baisha, Dihao, Yunyan, Hongtashan belonged to type 1; foreign cigarettes that represented by Marboro, Blue pacific and Brazil cigarette belonged to type 2. The content of malic acid and citric acid in type 1was higher than type 2, the content of malonic acid was higher in type 2, and there is no difference between the type 1 and type 2 about the content of polyphenols. In conclusion, the content of malic acid and citric in Chinese cigarettes was higher than foreign, but the content of malonic acid was lower than foreign. There is no difference between Chinese cigarettes and foreign cigarettes about the content of polyphenols. | Lan MI Bilong DAI Yu QIN Wenjun ZHANG Zhen XIONG Yanhong WANG Ting ZHU | 2015 | Agricultural Science & Technology2015，16，10： | 0 |
| 2 | Laser compression via fast-extending plasma gratings显示文摘A method is proposed for compressing laser pulses by fast-extending plasma gratings(FEPGs),which are created by ionizing a hypersonic wave generated by stimulated Brillouin scattering in a background gas.Ionized by a short laser pulse,the phonon forms a light-velocity FEPG to fully reflect a resonant pump laser.As the reflecting surface moves with the velocity of light,the reflected pulse is temporally overlapped and compressed.One-and two-dimensional fully kinetic particle-in-cell simulations with a laser wavelength of 1μm show that in this regime,a pump pulse is compressed from 10–40 ps to 7–10 fs(i.e.,a few optical cycles),with a two-dimensional transfer efficiency up to 60%.This method is a promising way to produce critical laser powers while avoiding several significant problems that arise in plasma-based compressors,including an unwanted linear stage,major plasma instabilities,and the need for seed preparation. | Zhaohui Wu Yanlei Zuo Xiaoming Zeng Zhaoli Li Zhimeng Zhang Xiaodong Wang Bilong Hu Xiao Wang Jie Mu Jingqin Su Qihua Zhu Yaping Dai | 2022 | Matter and Radiation at Extremes2022，7，6： | 0 |
