为解决河道小水等生态流量的监测难题,实现水资源的精细化管理,北京市在部分河道断面采用三角形剖面堰使水位流量单值化,并开展堰上水头连续监测,通过典型断面不同水位流量的现场精测,与三角形剖面堰水位流量关系理论线进行比对分析,发现堰上水头在低水区间流量实测值与理论值偏差在误差范围内,因此可在小水时利用理论线进行水位推流、中高水利用率定线进行水位推流。三角形剖面堰可推广应用于北方典型河道,满足防洪、景观、水资源、水质考核等要求,更有助于生态流量、海绵城市项目典型断面等水量监测。

以2021年春季潮白河生态补水为研究基础,利用GMS-Ugrid模块构建非结构地下水流模型,评价生态补水效果和地下水响应。潮白河生态补水总量(至2021年5月27日)为2.06亿m^(3),补水入渗量为1.57亿m^(3)(约占76%)。补水后1个月内,研究区第一含水层系统储存量增加了1.49亿m^(3);以水位0为影响范围分界线,补水影响面积达到842.8 km^(2)。距河道不同位置观测井滞后响应时间也不同,离河道3 km观测井水位抬升明显,滞后响应时间较短(3~6 d);远离河道地下水响应的滞后性明显,离河道6 km观测井滞后响应时间较长(18~30 d)。

A 10-channel Hα diagnostic system has been designed with the rapid response rate of 300 kHz, spatial resolution of about 40 mm, and overlap between adjacent channels of about 3%, and it has been implemented successfully on Keda Torus eXperiment(KTX), a newly constructed, reversed field pinch(RFP) experimental device at the University of Science and Technology of China(USTC). This diagnostic system is a very important tool for the initial KTX operations. It is compact,with an aperture slit replacing the traditional optical lens system. A flexural interference filter is designed to prevent the center wavelength from shifting too much as the increase of angle from vertical incidence. To eliminate the stray light,the interior of the system is covered with the black aluminum foil having a very high absorptivity. Using the Hαemission data, together with the profiles of electron temperature and density obtained from the Langmuir probe, the neutral density profiles have been calculated for KTX plasmas. The rapid response rate and good spatial resolution of this Hαdiagnostic system will be beneficial for many studies in RFP plasma physics.

为了确定鲁西金岭岩浆侵入杂岩体中的角闪石岩包体成因,对该类包体进行岩相学、矿物化学和地球化学分析。结果表明,角闪石岩包体具有明显的堆晶结构,主要由角闪石和少量斜长石组成。其中,角闪石可以分为两类:一类为韭闪石,具有较低的Si O2含量和较高的Al2O3含量,是原生角闪石;另一类为阳起石、镁角闪石和浅闪石,相对富集Si O2,贫Al2O3,可能为原生角闪石晚期被改造的产物。利用角闪石全铝地质压力计对原生角闪石进行压力计算,获得其平均结晶压力为0.48 GPa。这些角闪石岩包体的微量元素特征与寄主岩石黑云母闪长岩相似,均富集轻稀土元素,亏损重稀土元素。结合原生角闪石的形成条件,可以认为这些角闪石岩包体可能与寄主岩石同源,是中地壳岩浆房闪长质岩浆分离结晶的产物。

小包庄铁矿位于长江中下游成矿带庐枞火山岩盆地中,是近年发现的又一大型玢岩型铁矿床。本文基于详细的岩相学、矿相学观察,对小包庄铁矿的围岩及典型矿物的主微量元素、硫同位素、流体包裹体进行了分析测试,结果显示,小包庄铁矿磁铁矿矿石中不同成矿阶段形成的黄铁矿、硬石膏的δ34S值异常高,黄铁矿集中在6‰~15‰之间,硬石膏集中在16‰~24‰之间,并且随着成矿期次由早到晚、深度由深到浅,黄铁矿、硬石膏的δ34S值逐渐降低,同时测得小包庄铁矿下部三叠系东马鞍山组膏盐层的δ34S值为30.1‰,反映了小包庄铁矿有膏盐层硫的加入。包裹体测温结果表明,小包庄铁矿透辉石-磁铁矿-硬石膏化蚀变阶段、绿帘石化蚀变阶段、碳酸盐-硬石膏-黄铁矿化蚀变阶段和硬石膏-石英-黄铁矿化蚀变阶段的成矿流体温度分布区间分别为326~496℃、259~317℃、178~280℃和107~189℃,盐度分布区间为14%~21%NaCleqv、11%~20%NaCleqv、6%~16%NaCleqv、2%~13%NaCleqv,成矿流体经历了从高温高盐度向低温低盐度演化的过程。从成矿岩体、矿体矿石特征、蚀变分带以及成矿温度等方面与罗河铁矿进行对比表明,小包庄铁矿与罗河铁矿为同一类型的两个独立矿床,其在空间上上下叠覆的模式可能是由闪长质岩浆在不同深度侵位造成的。
