试论日本古代国家官僚制度

五位以上的有位贵族依据"官位相当制",在官僚机构内部担任高官,并在服制即朝服和礼服方面与六位以下官人相区别。有位贵族在政治、经济、法律和受教育方面具有很大的特权,享有一系列的优惠待遇。官人的出身资格大体分为五位以上官人的子孙的荫子孙、六、七、八位官人之子的位子和除此之外的白丁三种。荫位制,是五位以上的有位贵族子孙的主要出身之路。日本的学校与官吏出身制度的联系不是很密切,日本的学校的功能与其说是培养任用官吏的机构,不如说是在培养专家的同时,以使五位以上贵族子孙广泛了解经学为目的的一种经学传播机构。     

从张家山汉简《具律》看汉初“爵论”制度

爵位是汉代法律量刑时的一个重要标准,爵位的有无与高低决定着刑罚的减免与否。本从张家山汉墓竹简《具律》篇中有关内容出发,结合其它出土竹简及相关史料来讨论汉初“爵论”制度在法律规定及司法实践中的表现,并通过与秦律作比较来探讨其变化与根源。

Real‐time mud gas logging and sampling during drilling

Continuous mud gas loggings during drilling as well as offline mud gas sampling are standard procedures in oil and gas operations, where they are used to test reservoir rocks for hydrocarbons while drilling. Our research group has developed real‐time mud gas monitoring techniques for scientific drilling in non‐hydrocarbon formations mainly to sample and study the composition of crustal gases. We describe in detail this technique and provide examples for the evaluation of the continuous gas logs, which are not always easy to interpret. Hydrocarbons, helium, radon and with limitations carbon dioxide and hydrogen are the most suitable gases for the detection of fluid‐bearing horizons, shear zones, open fractures, sections of enhanced permeability and permafrost methane hydrate occurrences. Off‐site isotope studies on mud gas samples helped reveal the origin and evolution of deep‐seated crustal fluids.     

Kinship and mobility in 11th-century A.D. Gammertingen,Germany: an interdisciplinary approach

Excavation in and around a Medieval church in Gammertingen, Germany, revealed the skeletal remains of eight individuals dating to the 10th and 11th century AD. Archaeologists hypothesized that the individuals were the first members of a family later known as the Counts of Gammertingen, a medieval high nobility family. In an interdisciplinary approach, Strontium isotope and ancient DNA techniques were performed in order to test the hypothesis that the church was used as a family burial site and to investigate the provenance of family members. Seven of the eight individuals can be placed in a three-generation genealogy. The isotope analyses establish that the eighth individual had a different birthplace and possibly became a member of the Counts of Gammertingen through marriage. Further, genetic data revealed that distant relatives of the paternal lineage are still present in this area today. Thus, the combined results lead to a very detailed knowledge about a 1000-year old noble family.     

Geochemistry and origin of natural gases dissolved in brines from gas fields in southwest Japan

Previous geochemical studies indicated that most natural gases dissolved in brines in Japan are of microbial origin, consisting of methane produced via carbonate reduction. However, some of those from gas fields in southwest Japan contain methane relatively enriched in ¹³C, whose origin remains to be clarified. To address this issue, chemical and isotopic analyses were performed on natural gases and brines from the gas fields in Miyazaki and Shizuoka prefectures, southwest Japan. Methane isotopic signatures (δ¹³C ≈ ?68‰ to ?34‰ VPDB; δ²H ≈ ?183‰ to ?149‰ VSMOW) suggest that these gases are of microbial (formed via carbonate reduction) or of mixed microbial and thermogenic origin. The relatively high δ²H‐CH₄ values and their relationship with the δ²H‐H₂O values argue against the possibility of their formation via acetate fermentation. The δ¹³C‐CO₂ values (≈?5‰), together with the slope of the correlation between δ²H‐CH₄ and δ¹³C‐CH₄ (Δδ²H‐CH₄/Δδ¹³C‐CH₄ ≈ 1), contradict the possibility of their formation via carbonate reduction followed by partial oxidation by methanotrophs. The ³He/⁴He ratios of the gases from Miyazaki (≈0.11–1.3 Ra) and their low correlation with δ¹³C‐CH₄ values do not support an abiogenic origin. It is inferred therefore that the high δ¹³C‐CH₄ values of natural gases dissolved in brines from gas fields in southwest Japan are indications of the contribution of thermogenic hydrocarbons, although whether abiogenic hydrocarbons contribute significantly to the gases from Shizuoka requires further investigation. This study has clarified that, for the future exploration of natural gases in southwest Japan, we should adopt the strategies for conventional thermogenic gas accumulations, such as checking the content, type and maturity of organic matter in the underlying sedimentary rocks.     

Mineralogy and fluid inclusion gas chemistry of production well mineral scale deposits at the Dixie Valley geothermal field,USA

At the Dixie Valley geothermal field, Nevada, USA, fluid boiling triggered the precipitation of carbonate scale minerals in concentric bands around tubing inserted into production well 28–33. When the tubing was removed, this mineral scale was sampled at 44 depth intervals between the wellhead and 1227 m depth. These samples provide a unique opportunity to evaluate the effects of fluid boiling on the scale mineralogy and geochemistry of the vapor and liquid phase. In this study, the mineralogy of the scale deposits and the composition of the fluid inclusion gases trapped in the mineral scales were analyzed. The scale consists mainly of calcite from 670–1112 m depth and aragonite from 1125 to 1227 m depth, with traces of quartz and Mg‐smectite. Mineral textures, including hopper growth, twinning, and fibrous growth in the aragonite and banded deposits of fine grained calcite crystals, are the result of progressive boiling. The fluid inclusion noncondensable gas was dominated by CO₂. However, significant variations in He relative to N₂ and Ar provide evidence that the geothermal reservoir consists of mixed source deeply circulating reservoir water and shallow, air saturated meteoric water. Gas analyses for many inclusions also showed higher CH₄ and H₂ relative to CO₂ than measured in gas sampled from this well, other production wells, and fumaroles. These inclusions are interpreted to have trapped CH₄‐ and H₂‐enriched gas resulting from early stages of boiling.     

Sir Gawain and the green knight and the literary achievement of the north-west Midlands: the historical background

The author of Sir Gawain and the Green Knight and the other verse in BLMS. Cotton Nero A x ranks with his contemporaries, Chaucer and Langland, as one of the three great Middle English poets. Whilst this anonymous master and associated writers have been confidently ascribed to the north-west Midlands in the reign of Richard II, the social context of this literary achievement is still inadequately understood. Drawing on wider research on the social history of the region, and focusing on the career of one identifiable Cheshire poet of Chaucer's generation, this paper attempts to show what factors made this superficially inauspicious milieu at all conducive to high cultural attainment.The basic argument is that the richness and sophistication of the best north-west Midlands work are only comprehensible in terms of the considerable social mobility evidenced amongst the local population in this period. Large numbers of men from Cheshire and its environs can be traced in all corners of England, seeking their fortunes as soldiers, lawyers, clerks and merchants. This was the vibrant world in which the Gawain-poet and his fellows found not only appreciative audiences and generous patronage but also the new cultural influences and the courtly sophistication which characterise their more polished pieces.It is no coincidence that the last years of Richard II's reign, which witnessed the composition of the verse of BL MS. Cotton Nero A x, also saw the fortunes of local careerists soar to their apogee. In addition to their solid achievements in the professions, men from almost every family in Cheshire were being recruited into the royal household from 1397 onwards. With his well attested taste for fine literature, and with his extravagant generosity towards his Cheshire retainers, it is clear that if an aristocratic patron for the Gawain-poet is pre-supposed there is no more credible candidate than Richard II himself.
