Because of the ever-increasing consumption of crude oil, the role played bythe natural gas as a raw material has become more and more important in chemical industry and thepotential of methane used as a source for the production of ethylene has attracted much *** this paper, the LiCl-B_2O_3.MnO_2 and Li_2SO_4-Mn_xO_y/TiO_2 catalysts for Oxidative Coupling ofMethane (OCM) have been studied, and the results show that the catalysts exhibit high activity andselectivity. Furthermore, The influence of the components in the catalyst and the reactionconditions on OCM performance has been studied and a possible active new component, cubicLi_4B_7O_(12)Cl, has been found.

Based on the geo-temperature data of 13.systematically continuous temperature log curves and 700 testing oil boreholes in Jiyang depression, Shengli Oilfield, and the measured thermal conductivities of 47 rock samples, the terrestrial heat flow densities of 114 boreholes of Jiyang depression and its surrounding areas are determined, including 13.of those data derived from systemically continuous temperature logging. The results show that Jiyang depression has a relatively high background heat flow with an average value (65.8 5.4) mW/m2. The lateral variation of heat flow in basin has negative correlation with basement depth. Moreover, heat flow of uplift areas with shallower basement is high, so are those of regions with volcanic rocks, and those of depression areas with deep basement are relatively low. The heat flow densities of different structural units of Jiyang depression can be summarized as follows: The average heat flow value of Zhanhua sag is (67.4 5.3. mW/m2, higher than that of the whole basin, that of Dongying sag is (66.0 6.1) mW/m2, and that of Chezhen sag is (65.1 3.7) mW/m2. It is apparent that these latter two values are approximate to the average value of the whole Jiyang depression, while the average value of Huimin sag is (63.65.0) mW/m2, lower than that of the whole basin. In fact, the basement depth and the distribution framework of uplift and depression areas are all controlled by the process of lithosphere extension. In addition, the distribution of volcanic rocks in basin is also relatively close to this extension geodynamic process. In summary, the distribution characteristics of terrestrial heat flow of Jiyang depression is determined by the Cenozoic tectono-thermal events of this region.

内隐联想测验(Implicit Association Test,简称IAT)是Greenwald等于1998年提出的一种新的内隐社会认知的研究方法,其采用的是一种计算机化的辨别分类任务,以反应时为指标,通过对概念词和属性词之间的自动化联系的评估进而来对个体的内隐态度等进行间接测量。该文先对内隐联想测验的由来、原理进行了介绍,再从性能及应用两方面对已有的相关研究进行了归纳、整理和论述。最后,通过分析指出该方法符合现代心理测量学的最新发展方向,将有着强大的生命力。

According to the characteristics of water and erosion environments of different natural zones on the Loess Plateau, this paper studies changes of vegetation types, distribution boundaries of forest and grass as well as restoration capacity of vegetation in different natural zones in the middle Yellow River. The annual precipitation of 53. mm is the critical annual pre-cipitation for forest and grass distribution in the middle Yellow River. Among the zonal and azonal environmental factors affecting watershed sediment yield, the intermediate diameter D50 (mm) of suspended load and forest coverage (V, %) play the leading role. Of them the effect weight of forest coverage (V, %) on catchments sediment yield is only 3.4% less than the role of the intermediate diameter (D50, mm), they are almost the same. To effectively control soil erosion in semiarid, especially in hilly-gullied areas and make sediment transport modulus reduce to less than 6000 t/km2, it is rather difficult by merely relying on natural restoration of forest. In the process of cultivated land conversion into forest land and grassland, measures suiting local conditions should be adopted in tree species selection and artificial afforestation (grass planting) based on management with biological measures for slopeland and engineering measures for hilly-gullied areas, so that watershed forest coverage in key counties can reach at least over 3.%.Compared with the standard period of precipitation prior to the 1960s, with the decrease of an-nual precipitation at various periods, plant productivities decline to different degrees under natural conditions. The main reason accountable for the low survival rate of new seedlings and grass over years is due to precipitation decrease. In light with regression models of annual pre-cipitation and natural vegetation productivities, it is possible to obtain estimated values of wa-tershed natural vegetation productivity and eco-water consumption needed for the restoration to

自身是人格的核心,其发展取决于个体遗传特征与自身对象环境的相互作用。如果自身对象人格健全,就能满足个体的自身对象需要,自身对象在满足个体自身对象需要方面不可避免的疏忽只会使个体遭受适度挫折,适度挫折促使个体通过变形性内化获得原来由自身对象为其行使的心理功能,从而形成自身结构,使自身——自身对象关系从原始走向成熟。广义自身心理学的人格发展理论超越了古典精神分析、自我心理学和对象关系理论的人格发展观,但过分强调早期自身对象关系对人格发展的决定作用,忽视个体遗传特征和社会文化因素对人格发展的影响。
