明清目录中"《文心雕龙》子书说"考论

古代文学批评著作出现之初,传统目录学中并没有专门的类别予以归类.《隋书·经籍志》将《文心雕龙》(以下简称《文心》)、《诗品》等归入集部总集类.其后的《旧唐书·经籍志》、《玉海》等沿用同样的分类法.直到宋代《崇文总目》等设立"文史类",收录有关文学批评的著作,《文心》多被归入"文史"一类,此类又往往入集部.①     

试论清代的漕粮海运文化

晚清漕运的主体方式是海运,在6口余年的海运过程中,逐渐形成了以祭祀海神、修建会馆和撰写诗歌为特色的海运文化。这一独特文化现象的出现,既是清代漕粮海运的重要组成部分,也是当时社会风尚的合理延伸。     

天宝十三载封常清在交河郡的行程

吐鲁番阿斯塔那506号墓中出土的一批马料文卷,其中有几件是天宝十三载(754)交河郡柳谷馆、石舍馆、礌石馆、银山馆的马料帐,文书中记录了封常清在交河郡的行程.学界对此多有探讨,但均未考证出其中几件缺名马料帐之驿馆名称和地点,对封常清行程存在较多误解.实际上,四驿馆记载封常清在天宝十三载(754)往返北庭、安西并途经交河...

The salt chimney effect: delay of thermal evolution of deep hydrocarbon source rocks due to high thermal conductivity of evaporites

Half of the topseals to the world's largest oilfields are evaporites. Rock salt has a thermal conductivity two to four times greater than that of other sedimentary rocks found in oil‐ and gas‐bearing basins. Strong heat conduction through evaporites can increase the geothermal gradient above evaporite deposits, resulting in a positive thermal anomaly and above‐average temperature while simultaneously decreasing the geothermal gradient below evaporites, resulting in a negative thermal anomaly. Most Triassic–Jurassic hydrocarbon source rocks in the Kuqa Basin, western China, are overlain by ~1500‐m‐thick Tertiary evaporites with underlying Cretaceous sandstones and mudstones. Directly measured strata temperatures indicate an obvious break in the steepness of the geothermal gradient above and below Paleogene evaporites, with a significantly steeper geothermal gradient above the evaporites. Simulations of the thermal evolution of source rocks based on data collected from well Kela‐2 indicate that if the thickness of evaporites (mainly rock salt and anhydrite rock) in overlying rocks above source rocks increases compared with the thickness of siliciclastic rocks in the overlying rocks, then strata temperatures and vitrinite reflectance in Jurassic source rocks will decrease accordingly. Our thermal simulations based on the thickness and thermal conductivity of evaporites accurately coincide with previous studies based on homogenization temperatures, hydrocarbon–water contact retrospection, and carbon isotope results from natural gases. The gas generation center located in the Kalasu Tectonic Belt today is also sealed in an evaporite‐related structural trap that formed at this time. Therefore, the speculated natural gas generation times not only correlate with the evaporite‐related structural trap formation, but the calculated maturity of deep source rocks below the evaporites also coincides with current gas reserves. And our studies can help to find the deep oils and gases under thick evaporites.     

The People’s Liberation Army Rocket Force: reshaping China’s approach to strategic deterrence

The Chinese People’s Liberation Army (PLA) is in the midst of a sweeping reform programme to significantly transform its organisation, force posture, command and control structures, and internal politics. Among the many important aspects of this effort is the establishment of the PLA Rocket Force (PLARF). Creation of the PLARF solidified China’s missile forces as a critical element of China’s evolving strategic deterrent posture, portends continued significant investment in PLARF modernisation, and points to a more concerted effort to integrate PLARF capabilities into more effective PLA-wide joint operations—all key developments in the fundamental reshaping of China’s approach to strategic deterrence. These developments will affect U.S. strategic and extended deterrence postures, U.S.-China strategic stability, allied conventional force operations, information dominance and security, critical infrastructure, and other key aspects of national security. This study details the organisational, technological, and doctrinal changes afoot for the PLARF, and analyses how—if successful—they affect U.S. and U.S-allied military strategy in the Indo-Pacific region.

对女性生命价值的探寻--读白玉芳女士的《秋霄落雁女儿情》

白玉芳女干所的《秋霄落雁女儿情》,从少数民族女作家的视角描写了战争中的女性,本着重评论了女作家描写战争中女性所表现的特点,主要有三方面,一,女性生命生存状态的复现;承担与回避;二,历史场景中女性的理性与情感交错;三,神话事故与女性情绪的有机结合。
