东阳市自然资源“一体化”综合业务办公模式探索

2018年3月,自然资源部成立。2019年东阳市自然资源和规划局内部“三定方案”落地,实现东阳市自然资源管理机构由“分”到“统”的转变。这次机构改革不是对机构的简单合并或调整,而是更高层级下的职能重构和业务重组,需要更深层次的思想理念转变。自然资源管理部门,需要突破之前部门各自为政的困局,建立“一个整体”的概念,把工作放到自然资源的大局中通盘考虑,培养系统化的思维模式。同时需要进一步精简下放有关行政审批事项、强化监管力度,为保护和合理开发利用自然资源提供科学指引,更好发挥政府作用,强化自然资源管理规则、标准、制度的约束性作用。     

The Relation between the Amplitude and the Period of Solar Cycles

The maximum amplitudes of solar activity cycles are found to be well anti-correlated (r = -0.72) with the newly defined solar cycle lengths three cycles before (at lag -3) in 13-month running mean sunspot numbers during the past 190 years. This result could be used for predicting the maximum sunspot numbers. The amplitudes of Cycles 24 and 25 are estimated to be 149.5±27.6 and 144.3±27.6, respectively.     

利用历史有感地震目录（M≥3（1／2））研究华北地区地震活动性特征

对新编的华北地区历史有感地震目录（３（１／２）≤Ｍ＜４（１／２））的精度和可信度进行了讨论。认为该地震目录从１４８４年后的记载率较高，它的发震时间、震中位置和震级的精度基本可以满足研究历史地震活动性的需要。它与中国地震目录（Ｍ≥４（３／４））比较，补充了相当数量的３（１／２）≤Ｍ≤４（１／２）的地震。利用历史有感地震目录分析了华北北部部分６级以上的历史地震，结果表明，这些地震在强震发生前具有明显的空区、条带、地震活动性增强、平静等前兆特征，同时，也显示了某些强＊发生前的前震活动和主震之后起伏的强余震活动     

苏格兰西南部达拉德变质带中的大气降水渗入和氧前锋：区域金活动性的新假？

产于达拉德变质带黑云带中变质期后石英脉由三种主要类型组成：含黄铁矿的他形成英型，含赤铁矿的他形石英型和含赤铁矿或金红石的柱状石英型。他形石英脉中的氧化矿物由先存硫化物氧化而成，金在此氧化过程中被活化。成分相似的晚期柱状结构石英晶体经历了相分离的流体形成。脉中石英的氧同位素比值不等。成矿流体含有大量大气降水的成分，其同们素组成和化学成分随着水－岩相互作用而逐渐变化。金的活化转移与再沉积在片岩地层中随     

Experimental Research on Microscopic Indicators of Temperature＇ s Returning-to-Zero in Deformation of Calcite and Discussions of Correlation Problem

In order to determine the degree of returning-to-zero of temperatures of deformed calcite, a series of rock-breaking experiments were designed to test calcite-rich limestone samples under fixed confining pressures and different temperatures. The consolidated deformed samples in their initial state were observed under a microscope and the microscopic indicators in different zero-returning states were put forward, thus providing a microscopic foundation for evaluation of reliability of dating values of deformation in calcite. At last, the correction of dating values of deformation for samples whose temperature has not yet returned to zero is discussed.
