In near-field communication(NFC)antennas,soft magnetic ferrites are usually applied as a substrate to reduce eddy current loss and increase magnetic field *** this purpose,the applied ferrites are required to have high permeability and saturation magnetization together with low magnetic loss and dielectric ***,for most soft magnetic ferrites,it is difficult to meet all the *** novel Ni-Zn ferrite ceramics co-doped by Ho^(3+)and Co^(2+)ions with chemical formula Ni_(0.5-x)Zn_(0.5)Ho_(0.02)Co_(x)Fe_(1.98)O_(4)(x=0-0.2)were designed and prepared to balance these needs on the basis of molten salt synthesis with metal nitrates as raw materials and potassium hydroxide(KOH)as the precipitation agent and molten salt *** the substitution of Ho^(3+),the saturation magnetization and initial permeability decrease,but with further doping of Co^(2+),the saturation magnetization gradually increases,while the initial permeability continues to *** x=0.1,the sample will have the lowest dielectric constant,magnetic and dielectric loss,as well as the highest Curie temperature(305℃).Moreover,the acquired Ni-Zn ferrites have been applied simulatively in NFC antennas,revealing that the device manufactured with the optimal Ni_(0.4)Zn_(0.5)Ho_(0.02)Co_(0.1)Fe_(1.98)O_(4)ferrite ceramics would have significantly improved performance at 13.56 MHz with low leakage and long transmit distance of magnetic ***,the Ni_(0.4)Zn_(0.5)Ho_(0.02)Co_(0.1)Fe_(1.98)O_(4)ferrite ceramics would be a good candidate for NFC antenna substrates.

The ratios of the cross section of the transfer-ionization to the single-electron-capture of Argon induced by Cq+ (q=1,2,3) ions are measured by means of position sensitive and time-of-flight techniques. Our experimental results are compared with the data of Heq+ (q=1,2)-Ar of DuBois. A qualitative interpretation is presented based on the Classical-Over-Barrier Model of Bohr.

大陆风化是地球表层系统中的关键过程,涉及多种能量形式(太阳能、风能、化学能和重力势能)和物理化学过程,是地球化学元素在地球不同层面(如岩石圈、水圈、生物圈和大气圈)之间迁移和重新分配的基础。在此过程中,异常的元素富集可形成工业级的风化淋滤矿床。风化淋滤矿床可进一步区分出风化矿床和沉积—淋滤型矿床2种类型。传统的矿床学和沉积学研究方法在理解风化淋滤矿床形成过程中存在局限性,特别是在解析成矿阶段和动态成矿过程方面仍不甚明晰,导致该类型矿床在基础研究和勘查方面长期存在亟待解决的一批问题。本研究在厘清大陆风化作用、风化壳(古风化壳)、土壤(古土壤)等概念的基础之上,对现代风化淋滤剖面(如广西贵港三水铝石矿床)和古老风化淋滤型矿床(如中国华南地区早石炭世—晚二叠世铝土矿床及沉积淋滤型稀土矿床)开展了系统的沉积学分析与对比工作。研究发现,风化淋滤矿床的结构组分主要包括碎屑、团粒与包粒、块状黏土等结构类型,分别对应碎屑状、包粒状、致密状矿石的形成。成岩过程主要依赖于氧化物矿物及黏土质的胶结与填隙作用。基于上述认识,提出了风化淋滤矿床的淋滤序列和剖面结构划分方案。该方案以风化剖面中渗流带与潜流带作为基本的划分依据,进一步区分出风化矿床序列与沉积—淋滤型矿床序列,两者主要以是否出现沉积单位作为主要识别标志。以古气候为主线分析了风化淋滤矿床的成因机理,并结合近年来质量平衡计算相关成果,总结了淋滤过程中元素迁移规律,将风化淋滤型矿床的成矿过程概括为成矿母质形成、成矿物质风化和后期改造3个阶段。

随着我国页岩气勘探的推进,在局部地区已经取得突破并建成一定规模的产能,但天然气资源保障形势依然严峻,亟需加强拓展页岩气新层系沉积环境和富集规律,以进一步扩大页岩气的勘探范围和规模。贵州石炭系黑色页岩作为新发现的页岩气目标层,具有较好的页岩气勘探前景。由于受水城—紫云裂陷槽的控制,贵州石炭系沉积相变复杂,开展该页岩地层的沉积相和沉积模式研究,总结页岩沉积富集特征,有利于推进其页岩气勘探进程。本文通过研究揭示贵州石炭系页岩地层可划分为裂陷槽两侧边缘斜坡相,槽内过渡浅海—半深海相,裂陷槽内槽盆相,水城地区隆起浅海相,威宁地区潮坪—潟湖相沉积,总结具有裂谷边缘—槽盆滞留沉积模式。浅海相、浅海—半深海相、槽盆相、湖盆相是黑色页岩沉积富集的有利区,而具体地层厚度、黑色页岩发育、总有机碳含量(TOC)、干酪根类型受沉积环境和物源区的影响控制明显。
