近期在鄂尔多斯地块东北缘、蒙古高原南缘的乌兰哈达火山群附近发现一条长约100余公里的NW向断裂——乌兰哈达-高勿素断裂,并基于高分辨率卫星影像解译和野外地质调查对该断裂的新活动特征进行了初步研究。断裂活动的地貌证据包括线性展布的断层陡坎、断塞塘、断层槽谷以及位错冲沟、断头沟等。跨断裂冲沟的同步性左旋位错及广泛发育的反向陡坎(倾向NE)等指示断裂应为左旋走滑为主兼具由SW向NE逆冲的运动性质。乌兰哈达-高勿素断裂的构造位置及几何学、运动学特征指示其应归属于NW向左旋走滑的张家口-渤海断裂带,该断裂的左旋走滑运动应在调节其南、北两侧块体向E的差异运动中起着重要的作用。另一方面,鄂尔多斯地块东北缘的乌兰哈达-高勿素断裂及张家口断裂、洗马林断裂等NW向断裂所表现出的逆冲运动特征指示鄂尔多斯地块东北缘可能持续受到青藏高原东北缘对鄂尔多斯地块西南缘自晚中新世以来推挤作用远程效应的影响,这些伴有逆冲运动的NW向断裂应是鄂尔多斯地块东北缘地区响应青藏高原东北缘NE向生长和扩展的一种具体表现。乌兰哈达-高勿素断裂新活动证据的发现不仅完善了张家口-渤海断裂带的几何图像,也为认识和理解鄂尔多斯地块东北缘的构造变形和评价地震危险性提供了新约束。

在当前银行竞争加剧背景下,研究银行竞争对农村商业银行经营绩效的影响具有现实意义。文章通过分析我国银行竞争和农商行经营绩效现状,并选取2011—2022年202家农商行的数据建立动态非平衡面板数据,以ROA作为度量经营绩效指标、Lerner和HHI指数作为度量银行竞争度指标,采用系统GMM方法进行实证检验,得出结论:总体上银行竞争对农商行经营绩效产生显著负向影响;银行竞争对东、中、西部地区农商行经营绩效影响程度不同;总资产、存贷比、不良贷款率等指标均对经营绩效产生较大影响,其影响存在差异;净息差是银行竞争与农商行经营绩效间的中介渠道。针对结论与问题,文章从现代商业银行治理、加大资金运用、控制贷款风险、拓展非利息收入业务、加强监管等方面提出对策。

山西地堑系是华北中部的一个不连续的右旋剪切拉张构造带,这一观点似乎早已被学界所广泛认同。然而,目前仍缺乏对山西地堑系内部NNE向断裂右旋走滑特征的深入认识。本研究主要以山西地堑系北部六棱山北麓断裂的西段为研究对象,基于高分辨率卫星影像解译、野外地质地貌调查、无人机摄影测量和光释光测年等手段对断裂的晚第四纪运动学特征进行了厘定。跨断裂冲沟的一致性右旋偏转等表明断裂具有右旋走滑活动,断裂露头的构造解析及断层三角面、断层崖和冲沟裂点等指示断裂还具有正断分量。对断错地貌面和地质体的精确测量结果表明断裂应以右旋走滑为主,兼有正断分量,且走滑分量远大于垂直分量。结合年代学估算出断裂晚第四纪以来的右旋走滑速率为1.6±0.3 mm/a,垂直滑动速率约为0.2 mm/a。六棱山北麓断裂西段的右旋走滑速率与GPS测量的山西地堑系的右旋剪切速率大体相当,表明六棱山北麓断裂西段在山西地堑系的右旋剪切运动中起着重要的作用。六棱山北麓断裂西段的右旋走滑运动未被六棱山北麓断裂中段的水平拉张作用完全吸收和调节,剩余的应变分量可能继续向NE方向传递,故与六棱山北麓断裂西段走向基本一致的六棱山北麓断裂的东段也可能具有右旋走滑特征。

Chinese Journal of Reactive Polymers 2002年第2期11卷 177-184页

作者： SHAO Li ZHANG quanxing luo Gang CHEN Jinlong State Key Laboratory of Pollution Control and Resources Reuse Department of Environmental Engineering Nanjing University Nanjing 210093 China

The treatment of sorbic acid manufacturing wastewater by NDA-150 resin was investigated. The experiments show that this process is suitable for the treatment of sorbic acid manufacturing wastewater. About 98% sorbic acid and 50% CODcr were removed under optimal operating conditions, and 70% of sorbic acid in sorbic acid manufacturing wastewater was reclaimed. This process makes it possible to recover valuable materials from the wastewater and to improve the quality of effluent water.

淋巴结转移是影响胰腺癌患者预后的重要因素，然而单纯的淋巴结转移状态（即有或无淋巴结转移）并不能反映胰腺癌的淋巴结转移程度。淋巴结转移率即阳性淋巴结数目除以淋巴结检出数目，既反映了淋巴结转移的程度，又兼顾了淋巴结检出数目的影响，因而在辅助分期、指导治疗和预测预后等各方面都比单纯的淋巴结转移状态更准确。然而由于受淋巴结检出数目和界值不确定性的影响，淋巴结转移率尚无法取代淋巴结转移状态在胰腺癌中的地位，需要进一步的循证医学依据来证实和挖掘其潜在临床应用价值。
