Electron tomography(ET) has been demonstrated to be a powerful tool in addressing challenging problems, such as understanding 3 D interactions among various microstructures. Advancing ET to broader applications requires novel instrumentation design to break the bottlenecks both in theory and in practice. In this work, we built a compact four-degree-of-freedom(threedirectional positionings plus self-rotation) nano-manipulator dedicated to ET applications, which is called X-Nano transmission electron microscope(TEM) holder. All the movements of the four degrees of freedom are precisely driven by built-in piezoelectric actuators, minimizing the artefacts due to vibration and drifting of the TEM stage. Full 360° rotation is realized with an accuracy of 0.05° in the whole range, which solves the missing wedge problem. Meanwhile, the specimen can move to the rotation axis with an integrated 3D nano-manipulator, greatly reducing the effort in tracking sample locations during ***, in-situ stimulation function can be seamlessly integrated into the X-Nano TEM holder so that dynamic information can be uncovered. We expect that more delicate researches, such as those about 3D microstructural evolution, can be carried out extensively by means of this holder in the near future.

Temperature and pressure play key roles in Global Navigation Satellite System(GNSS) precipitable water vapor(PWV) retrieval. The National Aeronautics and Space Administration(NASA) and European Center for Medium-Range Weather Forecasts(ECMWF) have released their latest reanalysis product: the modern-era retrospective analysis for research and applications, version 2(MERRA-2) and the fifthgeneration ECMWF reanalysis(ERA5), respectively. Based on the reanalysis data, we evaluate and analyze the accuracy of the surface temperature and pressure products in China using the the measured temperature and pressure data from 609 ground meteorological stations in 2017 as reference *** the accuracy of the two datasets and their performances in estimating GNSS PWV are analyzed. The PWV derived from the pressure and temperature products of ERA5 and MERRA-2 has high accuracy. The annual average biases of pressure and temperature for ERA5 are-0.07 hPa and 0.45 K, with the root mean square error(RMSE) of 0.95 hPa and 2.04 K, respectively. The annual average biases of pressure and temperature for MERRA-2 are-0.01 hPa and 0.38 K, with the RMSE of 1.08 h Pa and 2.66 K, *** accuracy of ERA5 is slightly higher than that of MERRA-2. The two reanalysis data show negative biases in most regions of China, with the highest to lowest accuracy in the following order: the south,north, northwest, and Tibet Plateau. Comparing the GNSS PWV calculated using MERRA-2(GNSS MERRA-2 PWV) and ERA5(GNSS ERA5 PWV) with the radiosonde-derived PWV from 48 co-located GNSS stations and the measured PWV of the co-location radiosonde stations, it is found that the accuracy of GNSS ERA5 PWV is better than that of GNSS MERRA-2 PWV. These results show the different applicability of surface temperature and pressure products from MERRA-2 and ERA5 data, indicating that both have important applications in meteorological research and GNSS water vapor monitoring in China.

This report explored psychodynamic developments that adolescents undergo in their process of self-realization and self-identification, including separation-individuation and ego development. The paper maked a case for art therapy as a resource and non-confrontational outlet to guide adolescents through their development and search for their self-identity. The role of the art therapist is presented as an alternative source of support and containment which may be lacking through the adolescents’ peers and parents. The paper ultimately argued that art therapy had many therapeutic qualities that could help the adolescent in their search and consolidation of the self.

左归丸、右归丸是张介宾治疗肾脏阴阳亏损的重方,既往对二方的组方讨论多局限于君、臣、佐、使的配伍理论、药物功效及统计分析,至于二方如何创制的问题着墨不多。认为从张介宾医学思想的传承以及对药物的认知方面分析,左归丸、右归丸其实是张介宾取"六味之意",并依其真阴学说为核心,参以个人用药体悟而创制的新方。左归丸、右归丸在医方结构上具有同根的特点,用药之法也与《类经》和《景岳全书》中的记载相合,可视为张介宾将医理融于临证遣方的一种结果。

论文的目的是了解我国50多年来肾虚证本质研究概况。论文统计、分析CNKI、维普、万方数据库中收录自1960至2013年间肾虚证本质研究论文数量的变化趋势,借助地理信息系统技术,展现了不同时段内肾虚证本质研究在我国的开展情况。检索获得肾虚证本质研究文献618篇,明确了国内该领域的重要研究者19位,以及其所在机构和主要研究方向。发现有上海等6个地区在该领域具有明显的研究优势。论文的结论是:该领域重要研究者在研究路径上呈现多样化和差异化特征,已有研究成果主要集中于肾阳虚证,且研究方法和成果存在局限;研究人员在不同地区间的引入或流动不明显,彼此间也缺乏广泛合作;肾虚证本质研究对中医临床虽有指导,但与传统中医的肾藏学说却渐行渐远。

阴阳黄理论自宋代提出之后,并未如以前的医史研究者所认为的那样,顺利成为主流理论。比较张介宾(1563-1640年)和他前后的医家对阴阳黄理论的贡献,可以得出结论:明末张介宾在阴阳黄理论发展、完善和传播中起了关键性作用,他的工作是阴阳黄理论由不被重视转而成为黄疸主流理论的转折点。
