列宁对马克思主义关于社会主义及社会主义发展道路的理论进行了发展和创新,领导俄国取得伟大的十月革命胜利,建立了世界上第一个工农苏维埃政权,使科学社会主义从理论变成现实,开辟了资本主义向社会主义过渡的人类历史新纪元。列宁根据十月革命后苏维埃俄国的具体国情,提出了从“战时共产主义”政策转向“新经济政策”的战略决策,使苏维埃俄国找到了向社会主义经济阶段过渡的新道路。“新经济政策”是列宁对马克思主义关于社会主义和社会主义道路理论的补充、发展和创新。在资本主义从自由竞争向帝国主义过渡的背景下,列宁在领导俄国革命和斗争的实践中,对马克思主义哲学、政治经济学和科学社会主义进行了全面的、创造性的运用、补充和发展,为全世界人类进步作出了具有划时代意义的杰出贡献,是捍卫和创造性地发展马克思主义的典范。列宁关于民族和殖民地问题的理论为被压迫民族的民族独立斗争提供了宝贵的指导思想。在列宁主义的光辉照耀下,许多殖民地人民为摆脱帝国主义和殖民主义桎梏、争取独立和自由而斗争,并在获得解放之后选择了社会主义道路。越南革命领袖胡志明在列宁主义的指导下选择了无产阶级革命道路,将马克思列宁主义创造性地运用到越南革命实践中,带领越南人民取得了民族独立解放斗争的胜利。苏联解体、东欧剧变等严重曲折是国际社会主义运动的重大挫折,但这并不是社会主义的失败,而是苏联模式的失败。革新时期,越南共产党坚持并在创新中发展马克思列宁主义和胡志明思想,必将领导越南人民取得建设和保卫社会主义国家事业的胜利。

Applied Geophysics 2006年第4期3卷 210-217页

作者： An Yong wei lichun Yang Changchun Key Lab of Geophysical Exploration under CNPC China University of Petroleum Beijing 102249 China School of Natural Resource and Information Technology China University of Petroleum Beijing 102249 China Institute of Geology and Geophysics Chinese Academic of Science Beijing 100029 China

Highlighting and analyzing the geological features of faults and fractures in seismic data is particularly important for hydrocarbon exploration and exploitation since they are often essential for finding and delineating reservoirs. We apply edge-preserving smoothing （EPS） to seismic processing and propose a most homogeneous dip-scanning method. The method preserves the geological features, eliminate random noise efficiently, obtain dip information, and improve the accuracy of identifying the oil and gas traps.

关键词： Dip-scanning most homogeneous edge preserving smoothing signal to noise ratio.

Petroleum Science 2008年第4期5卷 388-394页

作者： Dong lichun wei Shun＇an Tan Shiyu Zhang Hongjing School of Chemistry and Chemical Engineering Chongqing University Chongqing 400044 China

A large portion of world＇s natural gas reserves are ＂stranded＂ resources, the drive to monetize these resources leads to the development of gas-to-liquids （GTL） and liquefied natural gas （LNG） technologies. LNG has the advantage of having been developed for the past 40 years and having an excellent safety record. GTL on the other hand is another option with substantial benefits, but its development stage and commercial viability are far behind LNG. This paper presents a techno-economic comparison of GTL with LNG, including technical development, plant efficiency, market potential for the products, and capital cost for the infrastructure. The aim is to give an overall view on both LNG and GTL and provide a perspective on the profitability of these two technologies.

Noise attenuation is necessary before and after stacking in the seismic data processing. We describe the filtering method based on differential equations, which transforms the filtering equations in the frequency domain or in the f-k domain back into the time or time-space domains, and use the finite-difference algorithm to solve the equations. The method does not require the seismic data being stationary; and the filtering parameters can vary at any temporal and spatial point. The application results of real data show that the method has a good processing quality.

阿兹夫定治疗新型冠状病毒感染的研究进展

福建医科大学学报 2023年第5期57卷 316-319页

作者：魏丽春(综述) 平潭综合实验区医院药剂科平潭350400

2019年12月,新型冠状病毒感染(Corona Virus Disease 2019,COVID-19)在湖北省武汉市暴发。截至2023年5月17日,全球已有766440796例确诊病例,死亡人数达6932591例[1]。严重急性呼吸系统综合征冠状病毒2(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2)属于冠状病毒科正冠状病毒亚科,其基因组被包膜并包含在大小为26~32 kb的单链RNA中[2]。SARS-CoV-2感染早期可能无症状,但若未及时干预则可能出现重症肺炎、呼吸困难或器官功能障碍,甚至死亡[3]。因此,高效抗COVID-19药物的研发与筛选尤为重要,而对已知药物的筛选也是主要研究热点。
