西周"尊老"风气及其原因新探

我国历来有"尊老"之传统,长久以来,"尊老"思想被冠以孝治的产物,但在商周革故鼎新之际,周代的开国者却遇着后代所没有的境遇,他们所施行的"尊老"思想,在很大程度上是为了借鉴殷商所以灭亡的因素,在他们看来,"尊老"问题能否贯彻是关乎国家兴亡的大事。     

试论唐代宫廷宴饮风俗及其影响

唐代宫廷通过征收赋税、内官进奉、外官进奉和外蕃进奉等手段使得国库丰盈，这样唐代宫廷就有余财频繁地举行宴饮活动。唐代宫廷宴饮的主要类型有节日宴会、皇帝游宴、皇家醣宴、庆功宴、朝会及伴随祭祀活动而举行的宴会、宫廷内宴、皇帝为任命的外官饯行宴、皇帝迎接外蕃的宴会。唐代宫廷宴饮中主要的佐乐活动有行酒令、乐舞表演、百戏游艺节目表演等，这些活动一方面有效地调节宫廷宴饮气氛，另一方面也使得唐代宫廷宴饮风俗具有更丰富的文化内涵。唐代宫廷宴饮风俗作为一种上层丈化，为唐代社会各阶层所效仿，同时这种风俗也被五代直接继承。     

Mesorbitolina (Cretaceous larger foraminifera) from the Yezo Group in Hokkaido,Japan and its stratigraphic and paleobiogeographic significance

In this paper, we describe an Aptian (Early Cretaceous) larger foraminiferal species Orbitolina (Mesorbitolina) parva from the limestone olistoliths in the lower part of the Yezo Group in the Yubari–Ashibetsu area, central Hokkaido and from limestone pebbles in the lowermost part of the Yezo Group in the Nakagawa area, northern Hokkaido. This is the first report of this species from the circum-North Pacific regions. Based on its occurrences, the shallow-marine carbonates, re-deposited in the lower part of the Yezo Group, are precisely assigned in age to the Late Aptian. Comparison of the lower part of the Yezo Group in central and northern Hokkaido indicates differences of the Aptian–Albian depositional history between the two areas. This study reveals that after Late Aptian, Mesogean key taxa (typical Cretaceous Tethyan biota) demised in the Northwest Pacific.

从壮族汉文《大宅颂》与《智城碑》看大唐文化之南渐

武周时期壮族文人留下的《大宅颂》与《智城碑》，是大唐文化与岭南文化之伟大结晶。本文从两碑及六舍坚固大宅遗址看武周时期大唐文化对南方文化之渗透与施及，以窥视唐王朝羁縻制度、儒家思想、建筑艺术及文体风格等对于岭南文化的影响，从而了解唐王朝之盛大及文化发展之规律和意义。     

雍正皇帝与永明延寿禅师

从雍正视永明延寿为历代禅德之最,视永明延寿为心心相印者,极为重视永明延寿著作之刊刻流布及以永明延寿思想为其评判的标准与依据等方面,可以见出雍正皇帝与延寿禅师在禅学思想上的密切联系。进而根据清初社会状况及佛教尤其是禅宗演变的大背景,就雍正对永明延寿禅师的极力推崇与高度评价的原因及影响作出系统分析。

北美自由贸易区竞争政策特征初探

北美自由贸易区竞争政策是继欧盟竞争政策之后的一种新型竞争政策合作模式，是当今区域经济集团竞争政策较理想的合作典范。与欧盟竞争政策相比较，其呈现出抽象性、避免法律真空现象产生、处理竞争争端方式的特殊性、具体规定的模糊性以及层次单一性等特征，其中抽象性、避免法律真空现象产生及处理竞争争端方式的特殊性．比较适合大多数区域经济集团的特点，宜应效仿，而其具体规定的模糊性和层次单一性，应在日后制定的区域经济集团的竞争政策中加以完善。     

Paleomagnetic Results of Later Paleozolic Rocks From Alashan Area of Western North China Block

In order to contribute to the Apparent Polar Wander Path (APWP) of the North China Block (NCB) , we collected paleomagnetic samples of Late Paleozoic rocks from the northern and southern margins of the Alashan (Alxa) terrane (the western part of Inner Mongolia and northern parts of Gansu and Ningxia Provinces) and adjacent regions. Laboratory work revealed different types of demagnetization behavior and isolated a higher temperature characteristic component in most of the samples. Results of IRM experiments show high thermal stability and high coercivities for the magnetic carriers in these rocks. The characteristic component passed the fold and/or reversal tests, suggesting that the characteristic components were probably primary. On the basis of comparing the paleomagnetic results with the geologic evidence, we discuss the tectonic implications. In the Late Paleozoic, the Alashan region had been part of the NCB and was not connected with the northern and southern blocks. During the Carboniferous Alash     

Discovery of High-Pressure Basic Granulite Terrain in North China Archaean Craton and Preliminary Study

High-pressure basic granulite terrain of 2.65 Ga from Jiouhuai'an in the junction of the Hebei and Shanxi provinces was discovered and reported recently. The three metamorphic mineral assemblages and their mineral reaction texture of the basic granulites have been identified, which represent three main metamorphic episodes of 1.4—1.5 Gpa, 800℃; 0.7—0.9 Gpa, 820℃ and 0.5—0.6 Gpa, 700℃. Their steep decompressional clockwise P-T path implies that a late Archaean continental collision and sole thrusting event perhaps occurred in North China Craton. This is important to study petrogenesis of high-pressure granulites, composition and texture of deep crust in North China Craton, and early Precambrian collision tectonism.
