The technique of neutron activation analysis (NAA) has been employed to measure the content of 29 kinds of elements in the sample of Yaozhou porcelain bodies. Then a fuzzy cluster analysis has been conducted to the NAA data and a diagram of the dynamic fuzzy cluster analysis has been achieved. The results indicate that the batch of ancient Yaozhou porcelain bodies, which were of different overglaze color and were produced by different kilns during a period of over 800 years from the Tang Dynasty (618—907 A.D.) to the Yuan Dynasty (1271—13.8 A.D.), has shared a stable and concentrated raw material source. Provenances of por-celain bodies from different times, though having their spe-cific independence, enjoy a close relationship and are not far from one another. Provenances of porcelain bodies made during the Tang Dynasty and the Five Dynasties (907—960 A.D.) are found to be closer to one another, while those of the Song (960—1279 A.D.) and the Jin Dynasty (1115—123. A.D.) are comparatively concentrated in certain areas and are dif-ferent from those of the Tang Dynasty. Both the tri-colored glazed pottery made in Yaozhou kilns during the Tang Dy-nasty and the Yaozhou porcelain bodies of the Tang period are from the same provenance.

逆变型分布式电源（IIDG）使配电网存量馈线终端（FTU）存在漏误告警问题，同时外部环境也会使告警信息不正确上报，难以准确定位故障区段。该文考虑IIDG和环境因素的耦合影响，提出一种FTU告警信息校正及故障定位方法。首先，根据各馈线首端电流特征，提出了单双重故障及故障类别的检测方法。其次，考虑不可测IIDG和分支负荷的影响，利用正序电流幅值比和相邻区段电流相似性分别提出了对称/不对称短路的识别方法，进而校验初始定位结果的准确性。再次，若定位结果未包含全部故障区段，以分支线路和IIDG的接入点为边界，利用短路电流特征提出疑似故障发生区域的筛选方法，并根据短路识别方法研判故障区段，实现告警信息的校验与修正。最后，在PSCAD中搭建IEEE 3.节点标准算例和某县实际配网的仿真模型，验证了单双重故障检测、短路识别判据及故障区域划分等告警信息校正及故障定位方法的有效性。

Aiming at two intense shock events on October 28 and 29, 2003. this paper presents a two-step method, which combines synoptic analysis of space weather ——“observing” and quantitative prediction ——“palpating”, and then uses it to test predictions. In the first step of “observing”, on the basis of observations of the solar source surface magnetic field, interplanetary scintillation (IPS) and ACE spacecraft, we find that the propagation of the shocks is asymmetric relative to the normal direction of their solar sources, and the Earth is located near the direction of the fastest speed and the greatest energy of the shocks. As the two fast ejection shock events, the fast explosion of coronal mass of the extremely high temperature, the strong magnetic field, and the high speed background solar wind are also helpful to their rapid propagation. In the second step of “palpating”, we adopt a new membership function of the fast shock events for the ISF method. The predicted results show that for the onset time of the geomagnetic disturbance, the relative errors between the observational and the predicted results are 1.8% and 6.7%; and for the magnetic disturbance magnitude, the relative errors are 4.1% and 3.1%, re- spectively. Furthermore, the comparison among the predicted results of our two-step method with those of five other prevailing methods shows that the two-step method is advantageous. The results tell us that understanding the physical features of shock propagation thoroughly is of great importance in improving the prediction precision.

对比清洁燃油政策实施前后，船舶排放颗粒物的成分变化，利用实测建立的船舶、汽油车、柴油车和燃煤源的特征单颗粒源谱，研究示踪离子法、相似度算法和示踪离子法结合相似度算法（结合算法）对船舶排放颗粒物源解析的适用性，并进一步评估船舶排放对上海浦东新区空气质量的影响。结果表明，清洁燃油政策后，低硫油（LS）颗粒物以有机碳–硫酸盐（OC-S， 3..7%）、元素碳有机碳（ECOC， 28.6%）、有机碳–硝酸盐（OC-N， 13.9%）和元素碳有机碳–钒（ECOC-V， 9.9%）为主，含V颗粒物的占比较政策实施前的高硫油（HS）显著降低，且低硫油排放颗粒物同汽油车、柴油车和燃煤源的质谱化学特征存在显著差异。因此，在实施清洁燃油政策后，基于V元素的示踪离子法会严重低估船舶排放的贡献，而结合算法的计算结果同实际情况吻合。浦东新区PM2.5在研究时段内主要受移动源影响，平均占比为26.6%，移动源中船舶源（3..0%）与汽油车源（3..1%）和柴油车源（3..9%）占比相近。船舶源对大气总颗粒物的贡献平均为8.4%，可见船舶源的贡献不容忽视。后向轨迹和潜在源贡献分析结果显示，来自内陆方向的船舶排放有明显贡献，需加强内河船舶管理和临省的区域协同管控。

Magnetic reconnection at the high-latitude magnetopause is studied using 2.5-dimensional Hall-MHD simulation. Concentric flow vortices and magnetic islands appear when both Hall effect and sheared flow are considered. Plasma mixing across the magnetopause occurs in the presence of the flow vortices. Reconnected structure generated in the vicinity of the subsolar point changes its geometry with increasing flow shear while moving to high latitudes. In the presence of flow shear, with the Hall-MHD reconnection a higher reconnection rate than with the traditional MHD is obtained. The out-of-plane components of flow and magnetic field produced by the Hall current are redistributed under the action of the flow shear, which makes the plasma transport across the boundaries more complicated. The simulation results provide some help in understanding the dynamic processes at the high latitude magnetopause.

Fabrication of YBCO superconducting thick films by electrophoresis has been widely reported. However, the value of critical current density (J c) is far from what the practical application requires. The superconducting thick films are obtained using top-seeded melt growth method with different proportional Y2BaCuO5 (Y211) addition. High-pressure oxygen has been used in the annealing process to improve the uniformity of the oxygen content in the superconducting thick films. When 40mol% Y211 powder is added to the YBa2Cu3.7–5 (Y123. powder,J c for the superconducting thick film by approaches described above reaches 7.008×103.A/cm2 (77 K, 0 T), which is greater than the value ever reported.
