Abstract:
东濮凹陷为临清坳陷重要的生油构造单元,是渤海湾盆地最具有油气勘探潜力的凹陷之一。其中前梨园洼陷是整个东濮凹陷增储的主要地区,为了揭示其热史及烃源岩热演化历史,首先利用5口典型井的镜质体反射率数据恢复了前梨园洼陷的热历史,结果表明前梨园洼陷在沙河街组沉积开始至东营组沉积末期,经历了两期裂陷作用,地温梯度出现两期峰值,为39℃/km~48℃/km和38℃/km~40℃/km。再以热史为基础,结合沉积和构造发育史及烃源岩地球化学资料,模拟了前梨园洼陷5口典型井6套烃源岩的成熟度演化历史,揭示了前梨园洼陷烃源岩成熟度演化受东营组沉积时期古地温场控制,6套烃源岩成熟度都在东营组沉积末期达到最高,这将为前梨园地区深层油气勘探提供参考。
The Dongpu sag is an important generation hydrocarbon area of tectonic units in the Linqing de-pression of the Bohai Bay Basin, which has the greatest potential for oil and gas exploration. The Qianliyuan sub-sag is the main area of increasing oil and gas reserves in the Dongpu sag. In order to reveal the thermal history and source rock thermal evolution history, the thermal history of the Qianliyuan sub-sag was reconstructed based on vitrinite reflectance data from 5 typical wells. The results show that Qianliyuan sub-sag has experienced two phases of rifting, and the geothermal gradient reached twice high peaks during the early stage of the Shahejie Formation depositional period (39?C/km - 48?C/km) and the late stage of the Dongying Formation depositional period (38?C/km - 40?C/km). Moreover, based on the thermal history results, combined with the sedimentary and tectonic histories and source rock geochemical data, six sets of source rocks maturity history of 5 typical wells were simulated in the Qianliyuan sag. The results reveal that source rock thermal evolution is controlled by the paleo geothermal fields of the Dongying Formation depositional period in the Qianliyuan sag. The maturity of 6 sets of source rocks reached a maximum at the late stage of the Dongying Formation depositional period. This work will provide reference for deep oil and gas exploration in the Qianliyuan area.

地质通报 , 2015,
Abstract: 松潘―甘孜造山带广泛分布着三叠纪花岗岩体,其成因对正确认识研究区花岗岩浆的动力学背景具有重要意义。地球化学分析表明,万里城岩体寄主花岗岩具有高的SiO2含量(69.43%~73.10%)和较高的全碱含量,具弱过铝质(A/CNK=1.01~1.12)特征,属于高钾钙碱性―钾玄岩系列I型花岗岩类。暗色微粒包体具较低的SiO2含量(52.85%~59.50%)和较高的Mg#值(45~63),为准铝质高钾钙碱性二长(闪长)岩。包体为典型的岩浆细粒结构,发育针状磷灰石、环带结构斜长石、瞳状石英、反鲍文序列的不平衡岩浆结构等。微量与稀土元素分析表明,包体起源于壳幔混合作用,是底侵的幔源玄武质岩浆与上覆壳源长英质岩浆混合的产物,混合的熔体经历了钛铁矿、黑云母等矿物的分离结晶,最终形成万里城暗色微粒包体。而寄主花岗岩则起源于纯的长英质陆壳,岩石具有较低的Mg#值(21~39)、中等的CaO/(MgO+TFeO)值、较高的K2O/Na2O和(Na2O+K2O)/(TFeO+MgO+TiO2)值等,指示源区主要为变杂砂岩类。综合区域地质资料,提出松潘―甘孜造山带内大规模花岗质岩体的形成主要受控于碰撞后伸展背景下的玄武质岩浆底侵加热。

地质学报 , 2014,
Abstract: 麻栗坝钼铜铅锌矿床位于三江特提斯成矿带的西南端,赋矿岩体为黑云母二长花岗岩,属于腾冲花岗岩带古永复式岩体小龙河序列。黑云母二长花岗岩锆石LA-ICP-MSU-Pb年龄为78.6±1.2Ma,属于燕山晚期,相当于晚白垩世;矿体中辉钼矿的Re-Os等时线年龄为78.5±3.7Ma,略晚于成岩时间,为本区首次获得的精确成矿年龄。其中,辉钼矿的Re、Os同位素特征,表明其成矿物质主要来源于地壳。麻栗坝钼铜铅锌矿床成矿年龄、成矿岩体年龄接近,约为78Ma左右,与小龙河岩体年龄(79~65Ma)在误差范围内一致,表明矿床的热液演化活动时间较短,矿化和成岩均发生在岩浆活动的早期阶段。它们同为燕山晚期,是新特提斯洋渐次东向俯冲过程中,地壳加厚重熔引发的岩浆活动与热液作用的产物。

Abstract: 粤北大宝山斑岩钼钨矿床赋矿岩体出露面积0.18km2,矿化主要以细脉状及浸染状产于斑岩及其内外接触带中。系统的薄片观察表明,该岩体岩性比较复杂,有碱长花岗斑岩、普通花岗斑岩、白云母二长花岗斑岩及白云母花岗闪长斑岩。本文分析了碱长花岗斑岩及白云母二长花岗斑岩锆石LA-ICP-MSU-Pb年龄,碱长花岗斑岩锆石年龄为166.6±2.1Ma,MSWD=1.17;白云母二长花岗斑岩锆石年龄为166.2±3.1Ma,MSWD=2.3。两个样品的锆石U-Pb年龄基本一致,表明大宝山斑岩钼钨矿床岩体形成于燕山早期。据斑岩矿床年龄、斑岩矿床在十杭带时空分布特征及华南地区中生代构造背景,提出大宝山斑岩钼钨矿床岩体的形成可能与侏罗纪太平洋洋壳向南西俯冲而引发的的十杭带深断裂构造活动复活有关。

基于六阶模型的同步发电机参数辨识方法比较
Comparison of Identification Methods for Synchronous Generator Based on Six-Order Model
 [PDF]


Smart Grid (SG) , 2016, DOI: 10.12677/SG.2016.61005
Abstract:
为使相量测量装置(PMU)的实测数据更加准确地对同步发电机的运行状态进行监测,有必要对同步发电机的参数进行实时辨识。本文把传统同步发电机六阶模型改写为矩阵形式,分别采用励磁电流与励磁电压作为控制变量,比较两种控制策略的异同,通过仿真实例分析发现两种模型的辨识结果基本一致。在优化算法上,考虑到Matlab处理矩阵的优越性,笔者采用矩阵形式的直接搜索算法与粒子群优化算法对参数进行辨识,并比较了两种优化方法的优劣性。
To make use of the PMU measured data more accurately for synchronous generator running state real-time monitoring, it is necessary to identify the parameters of synchronous generator in real time. Based on the salient-pole synchronous generator, its six-order parameter model is derived, which is transformed into a matrix form. Through the example simulation analysis, the excitation current and excitation voltage as control variables show that the two kinds of model identification results are basically the same. Considering the superiority of Matlab, the author uses the direct search algorithm in parameter identification and PSO to identify parameters and compare the ad-vantage and disadvantages of the two optimization methods.

Abstract: 基于样地实测数据和evi指数,定量分析了黑龙江省大兴安岭森林生物量空间格局,并利用arcgis软件的空间分析与统计工具,分析了气候区、海拔、坡度、坡向和植被类型对森林生物量空间格局的影响.结果表明:黑龙江省大兴安岭森林生物量为350tg,空间上呈聚集分布,生物量有巨大的增长空间.森林生物量密度大小顺序为:寒温带湿润区(64.02t·hm-2)>中温带湿润区(60.26t·hm-2);各植被类型生物量密度大小顺序为:针阔混交林(65.13t·hm-2)>云冷杉林(63.92t·hm-2)>偃松落叶松林(63.79t·hm-2)>樟子松林(61.97t·hm-2)>兴安落叶松林(61.40t·hm-2)>落叶阔叶混交林(58.96t·hm-2).随海拔和坡度的增大,森林生物量密度先减小后增加,并且阴坡大于阳坡.大兴安岭森林生物量空间格局随气候区、植被类型和地形因子的梯度变化表现出差异性,在区域尺度上估算生物量密度时,需要充分考虑这种空间差异性.?

Abstract: 赣东北蛇绿混杂岩是中国为数不多的新元古代蛇绿岩,对该蛇绿混杂岩带中的方辉橄榄岩和玄武岩类岩石进行元素地球化学研究,以探讨新元古代赣东北地区的构造动力学背景.研究表明,方辉橄榄岩具有低TiO2(0.02%~0.37%)、低K2O(0~0.02%)、低Na2O(0.02%~0.10%)和富MgO(40.81%~44.58%)特征,烧失量普遍较高(10.09%~13.47%),表明样品普遍遭受蚀变;稀土元素配分模式图和微量元素蛛网图显示,橄榄岩样品具有亏损地幔源区特征,同时兼有俯冲带流体交代的特征.玄武岩类SiO2含量主要为52.63%~56.19%,平均为55.00%,属安山玄武岩范围.岩石具低MgO(3.66%~6.46%),中等TiO2(1.14%~2.66%),高Al2O3(13.07%~15.27%)、Na2O(3.42%~5.03%) 的特征.安山玄武岩轻稀土富集((La/Yb)N=1.84~2.61),无明显Eu异常,稀土配分曲线呈右倾型;微量元素蛛网图中显示大离子亲石元素Th、Ba、U、Pb富集、高场强元素Nb、Ti亏损,可能系俯冲板片脱水产生的流体交代地幔楔所形成,TNT(Ta、Nb和Ti)的负异常指示赣东北蛇绿混杂岩的形成过程中可能遭受了陆源物质的混染,反映了消减作用的影响.方辉橄榄岩和安山玄武岩的地球化学特征表明赣东北蛇绿混杂岩的形成可能经历了多期演化,早期可能系古华南洋发生洋内俯冲作用,俯冲过程中释放的流体交代了俯冲带上的地幔楔,使地幔橄榄岩富集轻稀土.随后的弧后盆地扩张阶段,形成具有岛弧性质和MORB特征的玄武岩类,但由于弧后盆地发育不成熟,玄武岩类在地球化学上显示有大陆物质的特征,表现出高Pb、低Ti和轻稀土强烈富集.
The harzburgites and basalts from northeastern Jiangxi ophiolite belt have been investigated in the present study,with the aim to review Neoproterozoic tectonic environment.The results show that harzburgites are characterized by low TiO2 (0.02%-0.37%), K2O(0-0.02%) and Na2O (0.02%-0.10%),along with high MgO(40.81%-44.58%) and ignition loss(10.09%-13.47%),suggesting that the harzburgites suffered intensive alteration.The Chondrite-normalized REE patterns and primitive-normalized spider diagrams indicate that the harzburgites are sourced from a depleted mantle source suffered metasomatism in subduction zones.The data suggest that the meta-basalts are mostly characterized by high SiO2(52.63%-52.63%), Al2O3(13.07%-15.27%), Na2O(3.42%-5.03%) and low MgO(3.66%-6.46%), with medium TiO2 (1.14%-2.66%) contents, indicating that they are of andesitic basalt rocks. In a Chondrite-normalized REE plots, andesitic basalt rocks are rich in LREE((La/Yb)N=1.84-2.61) with smoothly right declined trend. The trace elements are characterized by enrichment in LILE such as Th, Ba, U and Pb and depletion in HFSE like Nb and Ti, indicating that andesitic basalts are derived from partial melting of enriched mantle wedge metasomatized by slab fluid in subduction belt,and the TNT (Ta, Nb, Ti) negative anomalies also imply those rocks may be contaminated by crustal materials. These geochemical characteristics indicate that the northeastern Jiangxi ophiolitic may have experienced multi-stage tectonic evolution.Harzburgites with LREE enrichments result from fluid metasomatism under intraoceanic subduction process in ancient Huanan ocean. Subsequently, island-arc tholeiite basalts and MORB-like basalts formed in the stage of back-arc basin evolution and those andesitic basalts contaminated with crustal materials,show strong enrichment of LREE,and with high

Retinitis pigmentosa (retinal pigmentary degeneration RP) in retinal photoreceptor is primary sensory cells—pigment epithelial complex abnormal retinal disease, which plays a progressive damage in visual function and has the characteristics of universality, inherited. The main symptom is night blindness, a centripetal narrow field of vision, dark adaptation ability etc. Blindness rate is high and difficult to cure, so early detection and early active treatment has an important significance for the stability condition and control development. We will present situation of acu-puncture treatment of retinitis pigmentosa as follows.
