In this study,we systematically analyzed the ground state of uranium isotopes from 225 to *** our calculations,we used the covariant energy density functional of density-dependent meson exchange interaction(DDME2)with separable pairing interaction(TMR).Using the multiple deformation constraint,we calculated the potential energy surface(PES)of the uranium isotopes for both even-even and even-odd nuclei with quadrupole and octupole *** on our calculation and upon comparing the experimental data and Hartree-Fock-Bogoliubov calculations with Gogny D1S calculation data,the ground state of uranium isotopes with reflection-asymmetric deformation was found to be preferred.

[目的]国内对休闲农业资源的概念、分类未形成统一的认知,空间研究中所选取的吸引物也众说纷纭,文章立足农业资源本体的视角对休闲农业资源进行分类并对成都市的空间格局进行实证研究。[方法]重点采用文献综合分析法探讨休闲农业资源类型和休闲农业吸引物的基本构成,并以成都市休闲农业为例,采用最邻近点指数、变异系数、网络维数、地理联系率、核密度估计等分析方法等对空间分布特征、产业协同特征和市场发展特征进行定量表征。[结果](1)成都市休闲农业在空间上趋于弱凝聚型分布,尚有较大的提升空间;(2)成都市休闲农业主要以精品花木、伏季水果、优质粮油等特色产业为支撑,空间集聚程度高,高密度区域主要集中温郫都(温江区、郫都区、都江堰市)花木产业金三角、龙泉山伏季水果产业带(青白江区、龙泉驿区)、邛崃—大邑—新津环主城平坝粮油区、锦江区、蒲江县茶叶产区等区域;(3)成都市休闲农业的发展呈现典型的"农区景区化"和"景区依托式"特征;(4)成都市休闲农业主要分布在30100km的环城游憩带范围,其中在3060km以及80100km的区域形成了密集带而在6080km的圈层形成了衰减带,且与当地市场联系程度较高。[结论]未来,成都市应重点强化休闲农业集聚区的带动效应,进一步提高优势特色农业和休闲农业品牌的影响力,加强休闲农业与当地客源市场的联系,优化衰减圈和远郊圈的道路交通系统和休闲服务设施体系,以推进休闲农业空间的全域、均衡发展。

Tuning of the magnetic interaction plays the vital role in reducing the clustering of magnetic dopant in diluted magnetic semiconductors(DMS).Due to the not well understood magnetic mechanism and the interplay between different magnetic mechanisms,no efficient and universal tuning strategy is proposed at ***,the magnetic interactions and formation energies of isovalent-doped(Mn) and aliovalent(Cr)-doped LiZnAs are studied based on density functional theory(DFT).It is found that the dopant–dopant distance-dependent magnetic interaction is highly sensitive to the carrier concentration and carrier type and can only be explained by the interplay between two magnetic mechanisms,i.e.,superexchange and Zener’s p–d exchange ***,the magnetic behavior and clustering of magnetic dopant can be tuned by the interplay between two magnetic *** insensitivity of the tuning effect to U parameter suggests that our strategy could be universal to other DMS.

血小板膜糖蛋白（GP）IIIa单克隆抗体SZ-21的完整IgG和Fab片段可抑制PLA 1同种抗体和PLA 1阳性血小板的结合且与剂量相关并在13mg/L浓度时趋于饱和。另外，血小板的SZ-21结合能力于PLA 1抗体存在时降低。在免疫印迹法中，PLA 1或PLA 2纯合子的GPIIIa都含有SZ-21识别的抗原决定簇。SZ-21不影响Yuk b同种抗体与其在GPIIIa上的靶抗原的相互作用。以上结果表明，单克隆抗体SZ-21在GPIIIa分子中的杭原决定簇非常接近PLA 1抗原决定簇但两者并不相同，而血清中PLA 1同种抗体的存在与其同SZ-21的结合竞争作用是相一致的。
