近年来移动气象服务需求快速增长,而气象信息的辅助决策功能在现代气象服务体系中的作用越发凸显,如何快速建立一个性能可靠、易于扩展、自主可控的移动气象服务系统成为当前各级气象部门重点关注内容之一。本文介绍了基于Hybrid模式构建精细化移动气象服务系统的总体设计,并通过Hybrid、插件化开发、MVC框架、HTML5融合等关键技术实现了气象信息在移动端的展示交互,体现了Hybrid开发模式在功能复用性高、迭代升级方便等方面的技术优势。经过近5年的持续迭代升级,目前系统产品已经广泛应用在山东省各级气象部门、政府决策部门以及重点服务行业中,在气象服务社会防灾减灾过程中发挥出重要作用。     

The Arunta Inlier: a complex ensialic mobile belt in central Australia. Part 1: Stratigraphy,correlations and origin

The Arunta Inlier is a 200 000 km² region of mainly Precambrian metamorphosed sedimentary and igneous rock in central Australia. To the N it merges with similar rocks of lower metamorphic grade in the Tennant Creek Inlier, and to the NW it merges with schist and gneiss of The Granites‐Tanami Province. It is characterized by mafic and felsic meta‐igneous rocks, abundant silicic and aluminous metasediments and carbonate, and low‐ to medium‐pressure metamorphism. Hence, the Arunta Inlier is interpreted as a Proterozoic ensialic mobile belt floored by continental crust. The belt evolved over about 1500 Ma, and began with mafic and felsic volcanism and mafic intrusion in a latitudinal rift, followed by shale and limestone deposition, deformation, metamorphism and emergence. Flysch sedimentation and volcanism then continued in geosynclinal troughs flanking the ridge of meta‐igneous rocks, and were followed by platform deposition of thin shallow‐marine sediments, further deformation, and episodes of metamorphism and granite intrusion.     

ESR assessment of kerogen maturation and its relation with petroleum genesis

Petroleum hydrocarbons are formed by breakdown of kerogen preserved in source rocks throughout the process of catagenesis. This process is accompanied by free radical generation in kerogen. The availability of measuring free radicals in kerogen using ESR to deduce a maturation estimation of potential source rocks has been hindered due to the presence of the solvent-extractable organic molecules (SEOM) trapped within the kerogen matrix. Spin concentration (Ns) of the kerogen treated with pyridine (K_Py) represents the paramagnetic centers of the kerogen matrix itself and provides a potential parameter to evaluate kerogen maturation.

首都圈地区重力变化及其映震能力

对首都圈流动重力观测成果进行非潮汐信息的提取，得到了首都圈地区１９８４—１９９３年期间的重力动态变化图像，认为重力变化与区域构造活动有一定的相关性。以大于２倍均方差作为异常判断标准，统计了北京小网的段差重力异常与地震的对应关系。结果表明：对于测网内发生的４级左右的地震，有异常出现的段差数占总数的１６．９％，对于距测网１００ｋｍ以内发生的５级以上的地震有异常出现的段差数占总数的３７．５％。西北部测环的段差异常出现率比南部和东北部高。
