| 1 | Studies on the isolation and culture of protoplasts from Kappaphycus alvarezii显示文摘In this study, protoplasts were successfully isolated from Kappaphycus alvarezii using snail enzymes, abalone enzymes and cellulase. The optimum enzymic ratio was fixed to be 20% of abalone enzyme, 12% of cellulase and the osmotic stabilizer was 2.0 mol/L glucose. The optimum enzymic hydrolysis conditions were found to be dark enzymolysis at 30°C continuing for 4.0 h. The resultant density and yield of protoplasts achieved 32.60×104 mL-1, 65.20×104 g-1 tissue for Kappaphycus alvarezii. Finally, under the temperature of 20°C, light intensity of 1 500–2 000 lx and photoperiod of 12 h/d, two developmental pathways were investigated:(1) callus-like cell mass and regenerated plantlet occurred on protoplast;(2) young shoots and calluslike cell mass occurred in tissue blocks after enzymolysis. | ZHANG Si LIU Cui JIN Yuemei CHI Shan TANG Xianming CHEN Fuxiao FANG Xu LIU Tao | 2014 | Acta Oceanologica Sinica2014，33，10： | 2 |

| 5 | Equilibrium electron beam parameters of the High Energy Photon Source显示文摘Purpose The physics design of the High Energy Photon Source(HEPS)was finished after many times of iteration.Hereby,the typical equilibrium electron beam parameters corresponding to the proposed two baseline operation modes in the baseline design of HEPS are presented.Methods To compute the equilibrium parameters of the electron beam,the lattice parameters,RF parameters,and the parameters of the insertion devices(IDs)were determined first.Furthermore,it is more precise to use the full-current electron beam parameters in the estimations of the performance of the synchrotron light.Therefore,not only the single-particle dynamics but also the current-dependent collective effects need to be considered in the computations of the full-current,equilibrium parameters of the electron beam.Both analytic computations and multi-particle tracking simulations were carried out.Results The full-current,equilibrium parameters of the electron beams in the HEPS storage ring are presented in this paper.Moreover,the main beam parameters in the injector(the booster and the LINAC),corresponding to the two baseline operation modes of the storage ring,are also presented.Conclusion The typical electron beam parameters corresponding to the two baseline operation modes are given in detail in this paper. | Haisheng Xu Cai Meng Yuemei Peng Saike Tian Na Wang Xiaohao Cui Chongchong Du Zhe Duan Yuanyuan Guo Ping He Xiyang Huang Daheng Ji Hongfei Ji Yi Jiao Jingyi Li Nan Li Xiaoyu Li Xiaohan Lu Pengfei Liang Weimin Pan Huamin Qu Bin Wang Jiuqing Wang Yuanyuan Wei Jinyu Wan Gang Xu Fang Yan Chenghui Yu Sen Yue Xiang Zhang Yaliang Zhao | 2023 | Radiation Detection Technology and Methods2023，7，2： | 0 |
