目的评价腹腔镜经膀胱内外2种途径修复儿童输尿管膀胱连接部畸形的治疗特点。方法收集2018年2月至2019年8月郑州大学第一附属医院收治的29例儿童肾积水合并输尿管扩张病例,其中男17例,女12例,均经术前检查确诊,输尿管膀胱连接部狭窄15例,输尿管反流12例,单输尿管开口异位2例。21例经气膀胱腹腔镜Cohen术式治疗,单侧17例,双侧4例,包含5例输尿管膨出,输尿管裁剪8例;8例经腹腔镜lich-Gregoir术式治疗,单侧7例,双侧1例,共裁剪4例,其中1例为重复肾合并上位输尿管髂血管外异位,1例合并双侧隐睾,1例合并单侧隐睾。对于所有输尿管裁剪的患儿给予输尿管内支架管植入,导尿管术后1周拔出,留置输尿管内支架术后6周左右全身麻醉下经膀胱镜拔出。结果29例肾积水合并输尿管扩张患儿均在腹腔镜下完成操作,无中转开放手术,无输血。气膀胱经腹腔镜组21例,单侧平均耗时1.8 h,双侧平均耗时2.8 h,腹腔镜lich-Gregoir组8例,单侧平均耗时1.7 h,双侧耗时3 h。平均随访9个月(4~20个月),所有患儿术后4个月排尿性膀胱尿道造影(VCUG)复查证实仅有1例出现膀胱输尿管反流Ⅲ级,其余均无膀胱输尿管反流,肾积水程度均减轻。1例双侧lich-Gregoir患儿术后出现短期尿潴留,留置导尿1周后症状消失,1例气膀胱Cohen组患儿术后出现血尿时间4 d,之后逐渐消失。2组患儿手术时间和术后恢复无明显差异,腹腔镜lich-Gregoir组术后住院时间略长于气膀胱经腹腔镜组。结论对于输尿管膀胱连接部畸形患儿,经腹腔镜lich-Gregoir术式适用于输尿管开口异位、输尿管过度扩张、合并腹腔内其他畸形、输尿管迂曲不明显者,气膀胱腹腔镜Cohen术适用于输尿管迂曲明显者、合并输尿管膨出且有排尿困难者。2种术式均安全有效,但在选择时需权衡利弊,择优采用。

Impact of T_(i)/T_(e )ratio on ion transport based on EAST H-mode plasmas

引用

Plasma Science and Technology 2024年第4期26卷 68-78页

作者：刘建文臧庆梁云峰陈佳乐邬潇河 Alexander KNIEPS 扈嘉辉金仡飞张斌储宇奇刘海庆吕波段艳敏李妙辉陈颖杰龚先祖 the EAST Team Institute of Plasma Physics Chinese Academy of SciencesHefei 230031People’s Republic of China University of Science and Technology of China Hefei 230026People’s Republic of China Forschungszentrum Jülich GmbH Institut für Energie-und Klimaforschung-PlasmaphysikPartner of the Trilateral Euregio Cluster(TEC)Jülich 52425Germany

At the EAST tokamak, the ion temperature(T_(i)) is observed to be clamped around 1.25 keV in electron cyclotron resonance(ECR)-heated plasmas, even at core electron temperatures up to 10 keV(depending on the ECR heating power and the plasma density). This clamping results from the lack of direct ion heating and high levels of turbulence-driven transport. Turbulent transport analysis shows that trapped electron mode and electron temperature gradient-driven modes are the most unstable modes in the core of ECR-heated H-mode plasmas. Nevertheless, recently it was found that the T_(i)/T_(e)ratio can increase further with the fraction of the neutral beam injection(NBI) power, which leads to a higher core ion temperature(Ti0). In NBI heating-dominant H-mode plasmas, the ion temperature gradient-driven modes become the most unstable ***, a strong and broad internal transport barrier(ITB) can form at the plasma core in high-power NBI-heated H-mode plasmas when the T_(i)/T_(e)ratio approaches ~1, which results in steep core Teand Tiprofiles, as well as a peaked neprofile. Power balance analysis shows a weaker Teprofile stiffness after the formation of ITBs in the core plasma region, where Ticlamping is broken,and the core Tican increase further above 2 keV, which is 80% higher than the value of Ticlamping in ECR-heated plasmas. This finding proposes a possible solution to the problem of Ticlamping on EAST and demonstrates an advanced operational regime with the formation of a strong and broad ITB for future fusion plasmas dominated by electron heating.

选择长三角地区具有代表性的4种土壤,采用不同浓度的外源Zn溶液进行吸附,用模拟雨水作为解吸剂,研究4种土壤对Zn的吸附-解吸特性,以及Zn的连续解吸特性.结果表明:4种土壤对Zn的吸附量均随吸附平衡浓度的增大而增加,且吸附量与土壤的pH正相关;吸附等温线可以用Freund lich方程和Temkin方程来描述.由Langmu ir方程求得的4种土壤的最大吸附量的大小顺序为:q(青紫泥)>q(滩潮土)>q(乌黄土)>q(黄泥沙田).最大缓冲容量的顺序为:MBC(滩潮土)>MBC(乌黄土)>MBC(青紫泥)>MBC(黄泥沙田).4种土壤对Zn的解吸量均随着解吸平衡浓度的增大而线性增加.连续解吸可提高土壤对Zn的解吸率,但连续解吸数次后,解吸过程趋于稳定.

镍钴锰三元层状氧化物(NCM)正极材料由于其优越的综合性能在动力/储能电池系统(ESS)领域得到广泛应用。虽然Ni含量的增加可提高三元材料的比容量及电池的能量密度,但相关电池体系的容量保持率和安全性将会变差。如何有效解决该矛盾是此类NCM电池所面临的关键问题。本文从NCM电池体系循环过程中常见的体相结构破坏和正极-电解液界面组成改变两方面失效现象出发,结合近年来国内外对NCM失效模式研究中所提出的新理论、方法、应用,从机械破坏、结构演变、电化学极化、化学副反应、正负极协同效应等多个角度对NCM材料的衰退机理提出见解,对指导电池用户合理制定充放电协议、缓解电动汽车(EV)里程焦虑乃至材料设计本身均有重要的指导及借鉴意义。

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particles, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that are new or heavily revised including those on： Dark Energy, Higgs Boson Physics, Electroweak Model, Neutrino Cross Section Measurements, Monte Carlo Neutrino Generators, Top Quark, Dark Matter, Dynamical Electroweak Symmetry Breaking, Accelerator Physics of Colliders, High-Energy Collider Parameters, Big Bang Nucleosynthesis, Astrophysical Constants and Cosmological Parameters. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews （and errata） are also available on the Particle Data Group website： http ：//pdg. lbl. gov.

From April to July 2018,a data sample at the peak energy of the T(4 S) resonance was collected with the Belle Ⅱ detector at the SuperKEKB electron-positron *** is the first data sample of the Belle Ⅱ *** Bhabha and digamma events,we measure the integrated luminosity of the data sample to be(496.3±0.3±3.0) pb-1,where the first uncertainty is statistical and the second is *** work provides a basis for future luminosity measurements at Belle Ⅱ.
