《史记》西周共和以后及东周年表初探

对《史记》“十二诸侯年表”、12“世家”和若干“本纪”的纪年与历日记载的分析表明：自西周共和以后及东周时期的纪年法,以次年王公纪年法为主流,当年王公纪年法为支流,并杂以若干非常规的王公纪年法;春秋时期共他诸侯国历法和鲁国历法大同小异,建正有建子、建丑之别;司马迁对这些纪年与历日的记述,是依据《春秋历谱谍》等可靠的史料作出的,其所构建的西周共和以后及东周年代,只有比例很小的失误,其整体是可靠的;西周共和元年是为公元前841年,可作为后计其后年代、前推其前年代的不可动摇的基本点。

Evolution of drainage systems and its developing trend in connection with tectonic uplift of Eastern Kunlun Mt.

The Eastern Kunlun Mt. had been subjected to uplift together with the Qinghai-Xizang (Tibet) Plateau before the Early Pleistocene, and yet the Mt, did not protrude out of the Plateau surface. During that period lakes spread all over the studied region, with the drainage systems being all short rivers flowing into the lakes. At the end of the Early Pleistocene, intensive tectonic uplift led to the rising of the Eastern Kunlun Mt. and made the Mt. protrude onto the Plateau surface. As a result, a fault depression valley formed extending nearly from west to east along the fault belt of the Southern Kunlun Mt. Lakes in this region died out, surface runoffs joined into the valley of the Southern Kunlun Mt. resulting in a large river streaming nearly from west to east. Around 150 kaBP, because of the strong differential movement, rivers, such as the Jialu River and the Golmud River, retrogressively eroded seriously, cutting through the Burhan Budai Mt. Then they pirated the large river and divided it into four portions. Owing to the uplift of the Eastern Kunlun Mt., strongly retrogressive erosion of the upper reaches of the Jialu River has made the watershed of the Buqingshan Mt. migrate 6–10 km southward since Holocene. At present, it remains a stronger trend of retrogressive erosion developing upward to the basin of the Yellow River Source and it seems that the Jialu River is scrambling for the streamhead of the Yellow River.     

帕米尔高原花岗岩漂砾风化穴初步探究

通过对东帕米尔高原一冰碛平台上花岗岩漂砾风化穴的仔细观察,根据发生部位和形态特征对风化穴进行分类,并结合当地地形、气温、降水等自然条件对风化穴的成因进行分析,初步认为本区花岗岩漂砾风化穴的主要类型为边墙形、蜂巢型、底穴型、沟槽型,是温差风化（含寒冻风化）、盐风化、风蚀和时间（倒数第二次冰期以来）因素综合作用的结果,其中谷风侵蚀在边墙型风化穴形成过程中起主导作用．     

Late Mesozoic–Cenozoic de′collement structure and its deep geological background in western Shandong, China

Data from seismic reflection profiles, drilling, stratigraphy, structural deformation studies and physical rock properties reveal the existence of de′col1ement structures in both shallow and deep levels in western Shandong, China. The most outstanding shallow de′col1ement structures occur along the regional unconformity surface between the Cambrian and Archean, and the disconformity surface between the Carboniferous and Ordovician. The de′col1ement structure surface manifests as a fault zone with cataclastic rocks and asymmetrical folds. Some of the cataclastic rocks underwent dynamic metamorphism and hydrothermal alteration, including silicification, marbleization and specularite mineralization. Above the de′col1ement structure, the bottom of the Cambrian might be missing or overprinted because of de′collement. The striations, asymmetrical folds and boudinage structures indicate the direction of the main de′collement to the NNW and NNE. A deep level de′collement structure occurs at a depth of 12–22 km and up to 30 km distance to the south. The early Cretaceous and Eocene are two main periods of activity, with the Cretaceous de′collement probably initiated by mantle upwelling derived from subduction and collision of the Yangtze Plate with the North China Plate along the Tancheng-Lujiang Fault in the late Triassic–early Jurassic. This circumstance implies a multidirection of subduction and collision of these two plates in the early late Mesozoic.     

鲁西隆起晚中生代以来北西向正断层特征及物理模拟

鲁西隆起区伸展构造极为发育,通过野外地质调查对隆起区北西向正断层的几何学特征进行研究,采用平衡剖面演化方法,选取横穿该区北西向断层的一条剖面,定量计算正断层横向上和垂向上晚中生代以来各主要构造演化阶段的构造运动学参数,并通过构造物理模拟实验详细解析鲁西隆起区伸展变形过程。研究结果表明,北西向控凹断层在三叠纪后皆发生负反转,晚中生代鲁西隆起受到强烈拉伸,伸展构造主要发生在19~20 km以下的深尺度范围内,断层切割深度加大。断裂带上普遍发育断层角砾岩、碎裂岩及断层泥。古近纪伸展作用以浅层拉伸为主,鲁西伸展量和伸展率最大,伸展作用强烈,对应北西向正断层的活动速率值也达最大值,同时发育大规模、范围广的半地堑。新近纪,伸展率很小,北西向正断层活动性大大减弱,至第四纪,断层几乎不再活动,反映鲁西隆起基本处于稳定。鲁西隆起晚中生代的伸展与华北克拉通构造变革相一致,而新生代的强烈伸展主要受控于太平洋板块与欧亚板块俯冲方向与速度的改变以及印度板块与欧亚板块的碰撞。     

三国两晋时期颍川郡佛教述论

三国两晋时期是佛教传入中土的初期阶段,当时的佛教活动中心北方主要集中在长安、洛阳,南方则在建康,而邻近洛阳的颍川郡（主要集中在郡治许昌）也有数位高僧的驻锡和游锡。高僧的佛教活动对颍川郡乃至中原的佛教发展产生了重要影响。但是两晋时期,许昌几易胡汉政权之手,政局不稳严重阻碍了高僧硕德在该地区传法弘教,故对此时的佛教活跃程度不宜估计过高。     

东汉空间天球概念及其晷漏表等的天文学意义——兼与托勒玫《至大论》中相关内容比较

论述了东汉《四分历》前后首次出现的一些球面天文概念,并把它们和古希腊有关概念进行比较;在此基础上,进一步探讨了《后汉书》中晷漏表和黄赤道宿度表的天文学意义,认为东汉时期在测算实践的基础上已经初步尝试并基本建立了一个空间天球模型。关于古代中国的"似黄纬",在托勒玫天文学中可以找到类似的概念。比较了东汉和古希腊对于太阳视赤纬、黄赤道坐标变换、昼夜长度和天体中天等的计算方法和考虑问题出发点的异同,前者比较重视测算实践,而后者则建立在球面三角学的基础上。东汉《四分历》为后世"歩晷漏术"确立了基本模式,在中国天文学史中具有重要地位。     

试析"的卢"成为凶马的原因

“的卢“马成为凶马大概产生于东晋南朝,其原因大约有五个方面:忌讳白色,南方少马,南人不习战,社会风气萎靡不振以及跨马一事在政治上所带来的风险.
