The present study examined the contributions of age, verbal ability, arithmetic ability, working memory, and executive function (EF) to the development of theory of mind (ToM). The results showed that age, arithmetic ability, working memory, and EF were significant predictors of the development of ToM, while verbal ability did not. And results from the hierarchical regression analysis suggested that, compared to EF, arithmetic ability and working memory were more important in predicting the development of ToM.  相似文献

The electronic structures and optical properties of graphyne consisting of sp-and sp 2-hybridized carbon atoms are studied using first-principles calculations.A tight-binding model of the 2p z orbitals are proposed to describe the electronic bands near the Fermi level.The results show that the natural band gap of graphyne originates from the inhomogeneous bindings between differently-hybridized carbon atoms.The interlayer interactions of bulk graphyne narrow the band gap to 0.16 eV and result in redshift of the optical spectral peaks as compared to single-layered graphyne.  相似文献

The emphasis of the paper is the theme of the works: “fair, kind, and true is all my argument”, for the theme is the spirit of the Sonnets. Only when one understands the theme, can one fully realize the literary and artistic value of Shakespeare‘s Sonnets. The perfect unity of “fair, kind and true” is the ideal state of Shakespeare‘s life. The sonnets which reinforce the theme are really “the rarest pearls of Elizabethan poetry”.  相似文献

The physio-chemical and chemical features of water in natural conditions are controlled by the weath-ering of bedrocks,local climate,landforms and other geo-environmental parameters. In order to un-derstand the characteristics of water and the origins of the dissolved loads in the rivers and in the ground waters of the Taklimakan Desert,western China,we studied the ions in the water samples col-lected from rivers and wells. We collected water samples from four rivers (Keriya River,Cele River,Tumiya River and Yulongkashi River) in the southern desert and ground water samples from many parts of the desert. Major cations and anions were measured using ion-chromatograph and titration with HCl. The total dissolved solids (TDS),pH and conductivity were examined on site by a portable multi-parameter analyzer. The data show that the water in the rivers of southern Taklimakan is still of fresh water quality and slight alkalinity,although the TDS is comparatively higher than that of many other rivers of the world. The ground water is fresh to slightly saline,with TDS a little higher than that of river water in the study area. The concentration of ions is slightly different between the four rivers in the southern Taklimakan. However,the chemistries of ground water in all samples are to a large degree controlled by sodium and chloride. The ions in the ground water are concluded to be mainly from dissolving of evaporites,consistent with the dry climate in the region,whereas the ions in the rivers are mainly from rock weathering. Low-level human imprints are recognized in the ground water samples also.  相似文献

The genesis of H2S in the Weiyuan Gas Field, Sichuan Basin and its evidence   总被引:6,自引:0,他引:6  
The Sinian Dengying Formation gas pool in Weiyuan is the oldest large-scale sulfur-bearing gas field in China, which has a H2S content ranging from 0.8% to 1.4%. The Cambrian Xixiangchi Formation gas pool discovered recently above the Dengying Formation contains gas geochemical behaviors similar to those of Dengying Formation but different in sulfur isotopes of H2S. Investigations show that though these two Sinian and Cambrian gas pools are separate ones, they share the same Cambrian source rock. The higher dry coefficient, heavier carbon isotopes, sulfur isotopes of sulfide, lower filling of gas pools, formation water characteristics, reservoir properties and H2S distribution, indicate that H2S in both the Sinian and Cambrian gas pools originates from TSR. The sulfur isotopes of sulfates have shown that H2S was formed in respective pools, namely hydrocarbons charged into the pools reacted with the Dengying Formation and the Xixiangchi Formation gypsum (TSR), respectively, to form H2S. Compared with sulfur isotopes of sulfates in each pool, δ^34S values of H2S are 8‰ lighter for the Dengying Formation pool and 12‰ lighter for the Xixiangchi Formation pool, respectively, which is attributed to the difference in temperatures of TSR occurrence. The reservoir temperature of the Xixiangchi Formation pool is about 40℃ lower than that of the Dengying Formation pool. Temperature plays a controlling role in both the sulfur isotopic fractionation and amounts of H2S generation during TSR.  相似文献

Manpower is a key factor for the success of the CIMS Subject of China 863 Program. Many manpower strategies have been used in the CIMS Subject, which include elite strategies, training and practicing strategies, and culture strategies. This paper is mainly about the training and cul-ture strategies such as to pay attention to the training and the practice of the technical team, and to form a fine CIMS culture.  相似文献

Rhyolite is the most viscous of liquid magmas, so it was surprising that on 2?May 2008 at Chaitén Volcano, located in Chile's southern Andean volcanic zone, rhyolitic magma migrated from more than 5?km depth in less than 4?hours (ref.?1) and erupted explosively with only two days of detected precursory seismic activity. The last major rhyolite eruption before that at Chaitén was the largest volcanic eruption in the twentieth century, at Novarupta volcano, Alaska, in 1912. Because of the historically rare and explosive nature of rhyolite eruptions and because of the surprisingly short warning before the eruption of the Chaitén volcano, any information about the workings of the magmatic system at Chaitén, and rhyolitic systems in general, is important from both the scientific and hazard perspectives. Here we present surface deformation data related to the Chaitén eruption based on radar interferometry observations from the Japan Aerospace Exploration Agency (JAXA) DAICHI (ALOS) satellite. The data on this explosive rhyolite eruption indicate that the rapid ascent of rhyolite occurred through dyking and that melt segregation and magma storage were controlled by existing faults.  相似文献

With the spherical harmonic (SH) function model and the dual frequency GPS P code phase data from the Crustal Movement Observation Network of China (CMONOC) during the period from year 2000 to 2002, time series of total electron content (TEC) in the area of China is calculated. The diurnal variations, semiannual, and winter anomalies of the ionosphere in the area of China are analyzed and discussed, especially according to the results of year 2001.  相似文献

This paper introduced the theory and approaches of building driving force models revealing the changes in land utilization level by integrating RS, GPS, and GIS technologies based on the example of Yuanmou County of Yunnan Province. We first created the land utilization type database, natural driving forces for land utilization database, and human driving forces for land utilization database. Then we obtained the dependent and the independent variables of changes in land utilization level by exploring various data. Lastly we screened major factors affecting changes in land utilization level by using the powerful spatial correlation analysis and main component analysis module of GIS and obtained a multivariable linear regression model of the changes in land utilization level by using GIS spatial regression analysis module.  相似文献

女子教育一直是近、理代小说关注的重要问题之一.中国近.现代小说不仅蕴含有丰富的女子教育思想,还记录了近代中国女子教育的变革过程,其变革路径在小说中清晰可见.清末民初,小说家配合教育救国的时代呼唤,主张兴女学,积极为女子争取教育权利,强调培养“贤妻良母”的重要性;20世纪二三十年代,经历“五四”个性解放,小说家把重点逐渐从提倡女子教育转移到男女教育平权的实现方面.随着妇女解放运动的深入,女子开始走向社会,培养“社会人”成为新的教育目标.  相似文献
