辛亥革命与中国共产党的成立

中国共产党的诞生,是近现代中国历史发展的必然产物,是中国人民在救亡图存斗争中顽强求索的必然产物。这种必然性,内在地反映了中国共产党的成立这一“开天辟地大事变”与辛亥革命这一“开启了中国前所未有的社会变革”间的关系。辛亥革命为中国共产党的成立准备了条件,即从一定意义上讲,它为中国共产党的成立奠定了阶级基础、思想基础、组织基础与政治基础。

A new ornamented artefact from Poland: final palaeolithic symbolism from an environmental perspective

An ornamented artefact made of antler, found in the environs of ?widwin (Pomerania, NW Poland), was subject to structural and environmental analysis. Radiocarbon dating (10?700 ± 60 BP or 10?910–10?680 cal. BC) places it in the Final Palaeolithic, at the end of Weichselian (boundary of the Allerød and Younger Dryas). The surface of the artefact bears a complex ornament of zigzag lines and an anthropomorphic drawing, representing most probably a woman with spread legs. Palynological analysis of the deposit in which the object was found indicates forest communities (pine-birch forests) with some open areas, in a cool climate. Ultrastructural examination points to the elk Alces alces (Linnaeus, 1758) as the source species; the antler was at the stage of intense growth which indicates that the elk was killed or died in the spring-summer period. The antler was large, and the object made of it was used for a long time, playing a role in rituals and symbolic culture of a hunting group. The ornamentation shows an affinity to the early Mesolithic art and makes it possible to better trace the relations between the hunters of the late Pleistocene and those of the early Holocene.     

再谈三线建设的评价问题

20世纪六七十年代进行的三线建设,虽已过去几十年了,但对它的评价依然存在颇多争议。对三线建设作出分析评价,确非易事,很大程度上归因于其特殊性。有鉴于此,有必要提出三线建设二重性这一命题,即它既是旨在应对战争危险的特殊政治行为,又是谋求改善生产力布局的一般经济行为。由于战争没有绝对确实性,只有相对确实性,因此政府的经济行为并不总是取决于经济学原则,还要考虑社会政治的要求。与此同时,评价三线建设得失时,还要面对其经济分析的特殊因素和难以避免的模糊性。总之,三线建设得失相比,得是长期起作用的因素,是国家战略利益所系;失是得的必要代价,从根本上说是外部敌对势力强加给中国人的,也是暂时的,终归会得到补偿。     

Mesopleistocene loess deposits in the Mamalyha 2 profile of Ukraine — interlaboratory comparison of the thermoluminescence dating results

The history of the interlaboratory comparison of TL dating results in Poland started in the 1980s. At that time the Lublin, Warsaw and Silesian laboratories made the first attempts at TL dating of the same loess samples from the Odonów profile. However, the cooperation ceased for many years due to great differences in the obtained TL age estimates. The next interlaboratory comparisons were made in the years 2000–2009 for the loess samples from several Polish (Dybawka, Tarnawce, Dankowice, Biały Kościół) and Ukrainian (Boyanychi, Halych, Velykyj Hlybochok, Yezupil) profiles. Most of the compared dates, obtained for the loess deposits from the Upper Pleistocene and younger part of the Middle Pleistocene, were consistent. This encouraged us to undertake the Gdańsk-Lublin interlaboratory cooperation in dating of 200-700 ka old loess deposits. Nine samples were taken from the Ukrainian profile Mamalyha 2 in 2009 for this purpose. The TL dating results indicate that comparable dates are obtained in two laboratories for loess deposits younger than 300 ka BP. The TL signal obtained in the Gdańsk laboratory for the samples older than 300 ka BP was saturated so such samples should not be dated by the multi-aliquot regeneration method. The results obtained in the Lublin laboratory for these deposits (489–682 ka) confirm that it is possible to date loess deposits older than 500 ka. It probably results from the use of total-bleach method with preheating at 160°C for the equivalent dose determination.     

OSL dating and lithological characteristics of loess deposits from Biały Kościół

Absolute dating using luminescence methods is widely applicable in geology, geomorphology, palaeogeography and in archaeology in establishing ages of sediments and archaeological artefacts. By creating absolute time scales for different events in the history of Earth scientists are able to reconstruct changes in climate and environment in the past, and the history of colonization and development of culture.     

Influence of climate change on carbon and oxygen isotope fractionation factors between glucose and α-cellulose of pine wood

We present the first analysis of the influence of climate change on carbon and oxygen isotope fractionation factors for two saccharides (glucose and α-cellulose) of pine wood. The conifers grew in the Niepo?omice Forest in Poland and the annual rings covered a time span from 1935 to 2000 AD. Glucose samples from acid hydrolysis of α-cellulose were extracted from annual tree rings. The carbon and oxygen isotope fractionation factors between glucose and α-cellulose were not stable over time. The mean value for the carbon isotope fractionation factors between glucose and α-cellulose was greater than unity. The mean value for the oxygen isotope fractionation factors between glucose and α-cellulose was lower than unity. We established, with respect to climate change, the significance of the interannual and intraannual variation in the carbon and oxygen isotope fractionation factors between both saccharides. We used moving interval correlation results for May of the previous year through September of the current year using a base length of 48 years. The relationship with summer temperature is the main climate signal in the carbon isotope fractionation factor between glucose and α-cellulose. The relationship with autumn sunshine is the main climate signal in the oxygen isotope fractionation factor between glucose and α-cellulose for the tree ring chronology.     

Holocene sediments of the Ustka Cliff (Northern Poland) in view of radiometric dating

The cliff in Ustka is an active one. The area is one of the most eroded sea shores of the Polish coast. The Ustka Cliff mainly consists of Holocene sandy deposits, but its basis is built of glacial till and clay. Field search allowed to recognize the structure and sedimentary conditions of Holocene deposits exposed in the cliff. A comparison of dating results obtained for fossil soils and peat as well as aeolian deposits, using ¹⁴C and TL methods, respectively, with available literature records is presented. The evaluation of results obtained allowed to define three main dune-forming phases for the first time for this part of the Polish coast. During the research studies new data on the processes and environmental conditions was gained and the development of structure of the area during the last 10 thousand years was reconstructed. The analysis of available data from other sections of the southern Baltic coast shows that results obtained are age similar to those determined for the ?eba Spit. The research is part of a project concerning the geomorphology of the Ustka Bay.
