The northward subduction of the Neo-Tethys oceanic crust triggered multiple magmatic activities in the West Myanmar Arc,which in turn influenced the deposition of sedimentary pyroclastic rocks from the Cretaceous to Eocene strata in the Central Myanmar Basin(CMB).The pore structure of these lithologic reservoirs is complex and rich in tuffaceous sandstone,which plays an adverse role in reservoir development in this *** understand the development characteristics and genetic mechanism of the pyroclastic rocks within three sets of reservoirs in this area,a comprehensive analysis was conducted through borehole core observations,thin section identification,scanning electron microscope analysis,and mercury injection *** tuffaceous sandstone from the upper Cretaceous to the Eocene is dominated by intermediate-acid volcanic rock *** pyroclastic rocks exhibit evident chloritization and ironization,with residual intergranular pores being the principal type accompanied by a smaller amount of intergranular dissolved pores and intragranular dissolved *** highest porosity is observed in the Eocene tuffaceous sandstone,ranging from 8%to 12%.The Late Cretaceous to Paleocene sandstones exhibit lower porosity levels of only 4%-6%.These reservoirs are characterized by their low porosity and *** the presence of a good source rock in this area,the volcanic debris particles filling the pores,as well as their subsequent devitrification,chloritization,and limonite mineralization,result in pore throat blockage and *** reservoirs in this area are small in size,exhibit poor reservoir connectivity and lateral continuity,and fail to meet the necessary conditions for commercial-scale hydrocarbon accumulation and migration.

苏门答腊盆地群是东南亚典型的弧后盆地,也是印度尼西亚第一大油气富集区,近5年发现新增油气储量呈上升趋势,待发现资源量大,具有较大的勘探潜力。通过系统梳理苏门答腊盆地群油气勘探历史、主要油气资源分布和盆地构造演化特征,分析了苏门答腊弧后盆地油气分布差异性及其主控因素。油气的不均一分布格局,主要受控于断陷期烃源岩的差异性分布,断陷期的“三阶段”构造演化过程控制不同类型的沉积环境及沉积相分布,进而影响主力烃源岩的分布;其次,地壳拉张变薄以及岩浆作用促使弧后地区浅层形成较高热流值,加速烃源岩的热解生烃。结合苏门答腊弧后盆地群油气勘探历史及其待发现油气资源量,认为苏门答腊盆地北部Andaman ⅢPSC区块等深水区、南苏门答腊盆地源下基底潜山新层系以及中苏门答腊盆地的陆上低程度勘探地区是下一步研究的新领域。

为提高针刺碳/碳(C/C)复合材料致密化效率和承载性能,分别设计了16 mm展宽布与网胎交替叠层的针刺预制体(B-NPs)、8 mm展宽布与网胎交替叠层的针刺预制体(H-NPs)及外层采用B-NPs结构、内层采用H-NPs结构的针刺预制体(T-NPs),联合化学气相渗透和浸渍-碳化工艺制备了3种针刺C/C复合材料。采用阿基米德排水法和X射线计算机断层扫描(Micro-CT)技术对3种针刺C/C复合材料的致密化效率、孔隙率和孔隙分布进行了统计,并开展了常温下三点弯曲力学性能测试。结果表明:随着展宽纱线宽度的增加,针刺C/C复合材料致密化效率得到提高,内部孔隙率有所下降。在相同的致密化时间内,B-NPs增密效果最佳,密度达到1.42 g/cm^(3),孔隙率仅为10.67%。三点弯曲载荷下,3种材料均表现出脆性破坏,其中T-NPs的弯曲强度和弯曲模量分别为173.04 MPa和20.66 GPa,具有优异的抗弯性能。3种材料的初始破坏位置均发生在针刺纤维束附近,其中低孔隙率的B-NPs针刺纤维束和碳布层破坏以纤维断裂为主;高孔隙率的H-NPs纤维/基体界面结合能力差,碳布层的破坏以纤维/基体界面脱粘和纤维拔出为主导。

采用三维纺织技术与树脂传递模塑工艺(RTM)制备了2.5D机织碳纤维-玻璃纤维/双马来酰亚胺树脂复合材料,分别在室温(25℃)和高温(150℃、240℃、300℃)环境下对复合材料进行了三点弯曲和层间剪切力学性能测试,探究了温度对复合材料力学行为及损伤机制的影响。结果表明:温度对2.5D机织碳纤维-玻璃纤维/双马来酰亚胺树脂复合材料的力学特性和损伤模式均有显著影响。温度上升导致纤维/基体界面结合力减弱,复合材料在300℃下的弯曲强度、弯曲模量和层间剪切强度相比室温环境分别降低了23.06%、70.01%和18.93%。弯曲载荷下,2.5D机织混杂复合材料的室温破坏模式主要以局部的纤维断裂和基体开裂为主,而高温损伤则以纤维/基体界面脱粘为主导。剪切载荷下,2.5D机织混杂复合材料的室温破坏模式主要为分层破坏,而随着温度升高,复合材料因基体软化出现塑性变形,基体开裂、界面脱粘及分层破坏决定了材料的最终失效。

共同富裕是满足人民对美好生活向往的重要方面,高等教育的振兴是事关经济与社会发展的关键因素。本研究选取黑龙江、吉林、辽宁东北三省2012—2021年36个城市共10年的数据,基于“富裕”和“共同”两个维度构建共同富裕指数,通过构建SYS-GMM模型分析东北三省高等教育对实现共同富裕的影响效应。研究表明:振兴东北三省高等教育将会显著促进共同富裕的实现,在其他变量保持不变的前提下,东北三省高等教育发展水平每提升1个单位,共同富裕指数提升1.452个单位;东北三省高等教育发展不仅能促进收入提升,还能有效缩小收入差距;东北三省产业结构在高等教育助力实现共同富裕的过程中发挥显著的正向调节效应,即产业结构优化升级将有助于东北三省高等教育推动实现共同富裕。因此,东北三省要全力加强高等教育强省建设,制定实施东北三省高等教育一体化发展与融通战略;要提高东北三省农村地区高等教育招生录取比例,促进教育成果服务地方惠及大众;要以“四个面向”为指引,推进东北三省产业结构升级,加强科研成果转化,构筑产教协同机制。

在现代化进程中,资本、技术、人力与土地的有机结合,使农村土地具有了较大增值空间,也给农村土地腐败带来了可乘之机。农村土地腐败问题之所以产生,利益驱动下的多元主体竞相介入获取利益是土地腐败的内在驱动力。不同利益主体之间通过各种策略相互博弈,在利益冲突中相互妥协并构建利益结盟,是土地腐败的实践过程表达。在多元主体参与的博弈中,权力主体与资本主体各有所图,权力主体在维护公共利益的同时追求个人利益,资本主体具有趋利性。为实现各自利益最大化,有权主体往往利用掌握的权力与能够带来巨大经济利益的资本主体相互交融、妥协,进而共谋,达成共识,侵害广大农民的合法土地财产权利,农村土地腐败由此产生。当然,防止土地腐败问题的发生,还需要从法制建设、制度建设等层面寻找突破口。
