美丽的夏夜     
正星星眨着眼睛,月亮悄悄地露出笑脸,萤火虫提着蓝色的小灯笼,在花丛中快乐地飞舞……这是一幅美丽的夏夜风景画。夏天的夜晚比白天凉快。晚饭后,我迫不及待地跑到广场上。看,广场上的人可真多呀!大人们有的在聊天,有的在散步,有的在唱歌,有的在跳舞,还有的在健身。小孩子们有的在滑滑板,有的在玩陀螺,有的在骑自行车,还有的在溜旱冰。我  相似文献

生命是什么?它浸染在五彩缤纷的秋色里,飘融在轻柔无语的冬雪中,在阵阵春雨里,在绚丽夏日中。它包含在老人爽朗的笑声里,也隐匿在孩子们天真的嬉戏中。它汹涌在人们的希望里,它荡漾在美好的祝福中。生命是什么?是欢乐,是领悟,是心灵深处的音乐。Life...Whatisit?Seeitinthecolo  相似文献

遇见孙燕姿     
戴望舒的《雨巷》——撑着油纸伞,独自,徘徊在悠长、悠长,又寂寥的,雨巷。我情愿逢着,一个丁香一样,结着愁怨的姑娘。她是有丁香一样的面庞,丁香一样的芬芳,丁香一样的哀怨,在雨中,哀怨又彷徨。携着珍贵的生命,走着人生的阡陌,我们会有无数的遇见。或在雨巷,或在雾街,或在风中,或在灯前,或在车厢的一隅,或在公路的尽头,或在天桥的拐角,或在地铁的出口方式并不重要,重要的是我们遇见,带着寻觅的目光与期待的心灵。  相似文献

正我的家乡在铁观音的发源地——西坪。家乡的那一片绿,一眼望不到头。走进这绿色的海洋,如同鱼儿在海洋中自由地穿梭,又像是飞鸟在绿色的天空里尽情地翱翔。家乡的那一片绿,绿得沉郁,在阳光的照耀下,在微风的吹拂中,漾起了绿色的涟漪。小时候,我喜欢在茶园里玩。走在茶园的小道里,我总会情不自禁地吹起悦耳的口哨。小鸡跟在我后面,演奏着  相似文献

地震震动了山河,震垮了房屋,但是它震不倒我们的心,也震不垮我们中华民族的魂。我们的主席、我们的总理,我们的军队,我们的白衣天使,我们的志愿者都在一线,和受灾的人民在一起;我们的后方在献血,在捐款,在捐物,在救死扶伤,在帮扶安置,在谋划重建家园,我们万众一心,我们众志成城。在大灾难面前,我们各尽所能,各尽所力,我们义无反顾地选择了作为企业公民和社会人应该承担的责任。 赈灾还在继续,我们做过的事,即使已经尽力了也不能抹去其反映的缺陷;可是我们能做的,我们还可以做的事还很多很多,因此我们要总结经验,吸取教训。在灾难中成长,为了接下来的赈灾工作,也为了面对将来可能发生的一切。  相似文献

美国的微生物研究员在二十世纪六十年代研究黄石国家公园温泉的时候,惊奇地发现在那些沸腾的水里,有许多原核生物在旺盛地生长着。这些原核生物不是很常见,是一些低等的藻类。它们依附在泉水边的岩石上,而它们长长的、纠缠在一起的细丝则在泉水里漂浮着。即使在那清澈透明,看起来没有任何生命的水池里,在显微镜下都会发现大量的微生物。甚至在沸腾的水里,也能发现这些微生物。更令人惊异的是,在沸腾的水里,这些微生物生长得更快;在不到两个小时的时间里,它们的数量就能增加一倍。微生物能在沸腾的水里生存,使得我们怀疑对生命来说,是否有一个温度  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the  相似文献
