Manganese Black Pigments in Prehistoric Paintings: the Case of the Black Frieze of Pech Merle (France)

Different black pigments of natural origin (mineral or organic) have been examined by means of several analytical methods (colour measurements, elemental analysis and structural analysis). The results, after being compared with each other, then served as reference points in the study of the ‘Black Frieze’ of the cave of Pech Merle (Lot). After that, colour measurement was investigated in situ on the paintings as a means of displaying small differences (in hue or chroma) between the black colours. The aim of this study was to verify several hypotheses concerning the techniques used by the painters of Pech Merle, and specifically by the one(s) of the Black Frieze. A first objective was that of identifying the nature and, if possible, the origin of the black pigments used in these figures. A second objective was that of determining in which parts of the frieze one or the other (or one and the other) had been used; and the final objective was to provide new technical information that might help us better to understand how the Pech Merle frieze was produced, whether by a single painter and in one episode, for the most part, or, on the contrary, in several episodes and by a succession of different painters.     

Neutron Activation Analysis of Metal Artefacts from the Moche Site,North Coast of Peru

Neutron activation analysis has been used to characterize 60 metal objects from the Moche site, of which four are associated with the Chimú Period, two with the Early Chimú Period and the others with various Moche IV contexts. Different types of utilitarian and non‐utilitarian objects were analysed to identify the metals present, and to investigate their chemical composition and their eventual source. The results clearly indicate the distinction between Chimú and Moche artefacts and confirm the generalized opinion that arsenic bronze was popular after ad 900. They also indicate that gilding copper objects with gold was already a common practice during the Moche era.

安徽铜陵师姑墩遗址出土原始瓷的初步分析研究

通过对铜陵师姑墩遗址出土的29件原始瓷进行的检测分析表明,师姑墩原始瓷胎为高硅低铝型,部分器物胎体的Fe_2O_3和TiO_2含量较高;釉属高温钙釉,釉中Mn和P含量相对较高,其可能由草木灰引入,部分器物釉中含较高的Fe_2O_3,致使釉色较深。这一结果为皖南地区先秦时期原始瓷手工业发展研究提供了新的科学依据。     

由二律背反到对立统一—科学发展观的理性审视

理性可以分为工具理性与价值理性,二者的应然状态应当是相互依存的对立统一关系,但随着物欲的恶性膨胀以及工具理性的片面发展,导致二者关系的扭曲与断裂,在实然状态下表现为“二律背反”。中国共产党提出的科学发展观破解了这一理性难题,实现了二者由“二律背反”走向对立统一。

论我国国民经济创造力的提升

国民经济创造力是生产力的核心。三次产业革命证明：在民主制度建立、实行自由经济体制、保障个人权利以及促进教育事业发展的条件下,国民经济创造力就得以开发和发挥。因此,我国必须坚持走改革开放的道路,促进国民经济创造力的形成和提升。
