We present resolved Giant Metrewave Radio Telescope H I observations of the high gas-phase metallicity dwarf galaxy WISEA j230615.06+143927.9(z = 0.005)(hereafter j2306) and investigate whether it could be a Tidal Dwarf Galaxy(TDG) candidate. TDGs are observed to have higher metallicities than normal dwarfs. j2306 has an unusual combination of a blue g-r color of 0.23 mag, irregular optical morphology and high-metallicity(12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find j2306 to be an H I rich galaxy with a large extended, unperturbed rotating H I disk. Using our H I data we estimated its dynamical mass and found the galaxy to be dark matter(DM) dominated within its H I radius. The quantity of DM, inferred from its dynamical mass, appears to rule out j2306 as an evolved TDG. A wide area environment search reveals j2306 to be isolated from any larger galaxies which could have been the source of its high gas metallicity. Additionally, the H I morphology and kinematics of the galaxy show no indication of a recent merger to explain the *** detailed optical spectroscopic observations of j2306 might provide an answer to how a seemingly ordinary irregular dwarf galaxy achieved such a high level of metal enrichment.

如何定量化核算Sc-cO2（超临界二氧化碳）破岩效率是非炸药类破岩技术在实际工程应用时重点关注的内容.本研究基于爆破当量理论计算和现场爆破试验的研究方法，通过工程类比法进行工业乳化炸药等效当量计算，选择典型代表性花岗岩及泥岩场地，设计进行了Sc-cO2与工业炸药破岩效应等效对比现场试验；基于现场破岩等效现场试验测试数据，对比分析试验过程中Sc-cO2与工业炸药破岩体积、破岩区域形态、大块率和单耗等破岩区域特征及参量数据.研究结果表明：当Sc-cO2破岩体积较大时，其致裂破岩范围的长短轴较长，并且随着剪切片厚度的增加，泥岩场地二氧化碳单耗的下降速率增大，二氧化碳单耗是炸药单耗的6～11倍.Sc-cO2破岩技术大块率较高，而炸药爆炸应力波分布均匀，大块率较小.Sc-cO2破岩地表振速远小于工业炸药破岩，工业炸药爆破测点合振速值为Sc-cO2破岩测点合振速值的9～11倍，Sc-cO2破岩对周边环境震动影响较小.Sc-cO2破岩测点合应力峰值高于工业炸药破岩，Sc-cO2破岩试验中各测点合应力值为炸药破岩试验中对应测点值的1.2～1.6倍.

在黑恶势力及其违法犯罪严重影响基层政权稳定的严峻形势下,党和国家决定开展扫黑除恶专项斗争,经过三年的全面、深入、系统推进,成效显著,赢得全面胜利。扫黑除恶是国家专门力量直接介入基层社会治理的重要体现,但单纯通过刑事司法或综合治理均无法达到深入且快速的良好治理效果。在总体国家安全观的指导下《,反有组织犯罪法》以“四个结合”为治理理念,构建惩防并举、标本兼治的有组织犯罪治理体系。其具体体现了司法治理与综合治理并重,且重点突出、有机衔接的共治路径及其立法思路。其中,司法治理强调宽严相济刑事政策的细化落实及关联治理机制的体系性完备,综合治理则突出群众路线下治本且治标的综合预防体系健全。通过不断完善的法治来推动常态化、高质效的有组织犯罪治理,保障扫黑除恶的法律效果、政治效果与社会效果相统一,有利于促进实现国家治理体系和治理能力现代化。
