用透射电镜对11例10～37周胎儿壶腹嵴暗细胞进行观察。发现:(1)10周胎儿的暗细胞已具有吸收功能的特征;14周的胎儿暗细胞出现了发达的胞浆突起,此时暗细胞已具有水和离子转运细胞的特征;17周时暗细胞的细胞器更加丰富,胞浆突起更加发达... 详细信息

用透射电镜对11例10～37周胎儿壶腹嵴暗细胞进行观察。发现:(1)10周胎儿的暗细胞已具有吸收功能的特征;14周的胎儿暗细胞出现了发达的胞浆突起,此时暗细胞已具有水和离子转运细胞的特征;17周时暗细胞的细胞器更加丰富,胞浆突起更加发达,以后阶段暗细胞的形态基本与17周时相似。(2)11周的胎儿暗细胞就已参与耳石的代谢。(3)壶腹嵴暗细胞区的黑色素细胞随暗细胞胞浆突起的发育而出现,说明二者关系密切。

Using ion beam biotechnology in combination with soil-less plant cultivation on artificial substratum (floating beds), the experiments were conducted with Ipomoea aquatica Forsk. Plants were attached to floating-beds which were placed on the surface of artificially nutrient-enriched tank water, in order to study the purification and remediation efficiency of ion beam-treated I. aquatica cultivars. The results show that N + ion beams with 25keV energy and dosages of 0, 2.6, 3.9, 5.2, 6.5, 7.8, 9.1×10 13N +(ions)/cm 2 affected I. aquatica dry seeds differently, with the dose of 3.9×10 13N + (ions)/cm 2 improving effectively the performance as expressed by various biological indices. After ion beam application, I. aquatica cultivars grew well in nutrient-enriched water bodies, increasing the growth of leaves and stem, number of leaves, length and area of roots, plant height, and weight more remarkably than observed in the control. The net removing rates of TN, TP were as high as 75% and 82%, respectively. Especially under the dose of 3.9×10 13N +(ions)/cm 2, the net removing rates of TN, TP were highest, for 77% and 85%, respectively. It was proved that ion beam application improves phytoremediation and may be used to purify nutrient rich water bodies.

Neutron Halo in Deformed Nuclei

Ti-Ni非晶合金贮氢薄膜制备及电化学性能研究

第十三届全国核结构研讨会暨第九次全国“核结构与量子力学”专题讨论会

作者： Shan-Gui Zhou~(1,2 1)) Jie Meng~(3,4,1,2) P.Ring~5 En-Guang Zhao~(1,2,3) 1(Institute of Theoretical Physics,Chinese Academy of Sciences,Beijing 100190,China) 2(Center of Theoretical Nuclear Physics,National Laboratory of Heavy ion Accelerator,Lanzhou 730000,China) 3(School of Physics,Peking University,Beijing 100871,China) 4(School of Physics and Nuclear Engineering Science,Beihang University,Beijing 100191,China) 5(Physikdepartment,Technische Universitat Munchen,85748 Garching,Germany)

Halo phenomena in nuclei are driving forces for the development of the physics with radioactive ion beams. They are threshold effects and have been first observed in the weakly bound system *** that most open shell nuclei are deformed,the interplay between deformation and weak binding raises interesting questions,such as whether or not there exist halos in deformed nuclei and,if yes,what are their new features. In order to describe adequately the halo phenomena in deformed nuclei,contributions of the halo,deformation effects,and large spatial extensions of these systems should be considered in a fully self-consistent way.A deformed relativistic Hartree Bogoliubov（DRHB） theory has been developed in which the DRHB equations are solved in a spherical Woods-Saxon basis with the proper asymptotic behavior at large distance from the nuclear center.
