招平断裂带北段构造控矿特征及找矿方向

招（远）平（度）断裂为胶东西北部三大控矿断裂之一。招平断裂北段玲珑金矿田范围内,向北分为NNE向九曲蒋家和NEE向破头青断裂,该文以它们的交会部位至2条断裂带在玲珑金矿田的结束部位及其所控金矿脉为主要研究内容,通过对招平断裂北段地质构造特征的研究,分析了招平断裂北段的形成和控矿机制,提出了破头青断裂不是控矿断裂的新认识,总结了该区金矿的赋存规律,预测成矿有利部位,提出找矿方向。

Seismic data reconstruction based on iterative linear expansion of thresholds

Based on the compressive sensing,a novel algorithm is proposed to solve reconstruction problem under sparsity assumptions.Instead of estimating the reconstructed data through minimizing the objective function,the authors parameterize the problem as a linear combination of few elementary thresholding functions,which can be solved by calculating the linear weighting coefficients.It is to update the thresholding functions during the process of iteration.The advantage of this method is that the optimization problem only needs to be solved by calculating linear coefficients for each time.With the elementary thresholding functions satisfying certain constraints,a global convergence of the iterative algorithm is guaranteed.The synthetic and the field data results prove the effectiveness of the proposed algorithm.     

基于SDCORS的车载RTK高程注记点连续采集精度分析

为提高航测法数字线划图(DLG)的生产效率,尽可能减少外业作业时间,基于山东省卫星定位连续运行综合服务系统(SDCORS)的车载RTK技术进行高程注记点采集。采用不同时间(白天、晚上)、不同车速条件进行高程注记点连续采集,并与常规方法(全站仪、单基站RTK)采集高程点进行比较,求取高程中误差,认为在夜间以不大于20 km/h的车速进行采集精度较高。在数字海阳基础地理信息数据采集项目中,利用车载RTK采集346 km2范围内的沿路高程注记点,结果表明能够满足1∶500航测法成图精度要求。

Identification of five sea cucumber species through PCR-RFLP analysis

Sea cucumbers are traditional marine food and Chinese medicine in Asia. The rapid expansion of sea cucumber market has resulted in various problems, such as commercial fraud and mislabeling. Conventionally, sea cucumber species could be distinguished by their morphological and anatomical characteristics; however, their identification becomes difficult when they are processed. The aim of this study was to develop a new convenient method of identifying and distinguishing sea cucumber species. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of mitochondrial cytochrome oxidase I gene (COI) was used to identifing five sea cucumber species (Apostichopus japonicus, Cucumaria frondosa, Thelenota ananas, Parastichopus californicus and Actinopyga lecanora). A 692 bp fragment of COI was searched for BamHI, KpnI, PstI, XbaI and Eco31I restriction sites with DNAMAN 6.0, which were then used to PCR-RFLP analysis. These five sea cucumber species can be discriminated from mixed sea cucumbers. The developed PCR-RFLP assay will facilitate the identification of sea cucumbers, making their source tracing and quality controlling feasible.     

山东福吉山铜矿构造控矿因素分析

福吉山铜矿成矿地质特点不同于山东已有的铜矿类型,属于构造热液成因类型。近SN向的平移断裂同时具有张扭性和压扭性双重力学性质,其中张扭性破碎带造就成矿空间,造成了矿体近等间距雁列式排列。受断裂构造的影响,矿区内节理、裂隙发育,为成矿热液的运移和积聚提供了良好的空间。区内沿裂隙充填形成的石英脉、褐铁矿脉、铜矿脉发育。     

海陆气候事件关联规则挖掘方法

近年来,异常气候事件的频发对人类的生活环境和经济发展带来严重负影响。气象学家研究表明：海洋气候异常对陆地气候异常事件的发生具有重要的诱发作用,因此,对海陆气候间的内在关联机制进行深入挖掘具有重要研究价值。本文提出了一种关联规则挖掘方法,以探索单一海洋气候指数与陆地异常气候事件间存在的关联。首先,针对陆地气候要素,采用顾及空间邻近关系的层次聚类方法进行有效气候分区,通过对各层分区结果进行相关统计分析得到有效的各区域气候序列;然后,进行顾及多重约束进行时序关联规则挖掘,以探索海陆气候要素间的关联机制;最后,通过实际算例分析得到的各气候指数与我国陆地区域异常降水事件间的关联机制结果,与实际情况高度吻合。
