解题教学中创新思维的激发与培养

创新思维是人类创造活动的灵魂和核心，学习数学离不开解题，数学思维能力的培养与提高是通过解题教学来完成的，在解题教学中应从增强问题意识，激发好奇心，发展直觉思维，多向思考等方面来激发和培养学生的创新思维。     

在数学教学中培养学生的创新思维能力

培养创新精神，提高学生的素质是实施素质教育的重点，是素质教育的灵魂和核心，是当今教育教学所要研究的重大课题，数学知识源于创新，又能促使人们进行新的创新，创新精神与思维寓于数学教学之中，数学教学能够且应该着力培养学生的创新思维。     

数学呼唤创新 创新激发潜能

数学被称作“思维的体操”，而数学创新意识就是它的精髓。如何培养学生逐步形成数学创新意识，并让创新激发学生的潜能，下面就谈几点实际教学中的体会。     

浅谈初中数学教学中的创新思维

在初中数学教学中，学生能力的核心乃是思维能力。加里宁指出：“数学是锻炼思维的体操”。可见学生思维水平是要通过数学教学活动去培养和发展的。全日制义务教育数学课程目标第四点提到：通过义务教育阶段的数学学习使学生具有初步的创新精神和实践能力。由此可见，创新教育已成为数学教学的一个重点，创新能力不是与生俱来的，是以课堂教学为载体培养出来的，我们每个教师义不容辞。本文对学生初中数学的创新思维浅谈自己的看法。     

在数学问题的反思中提高学习能力

数学教学是数学思维活动的教学，担负着培养学生数学思维能力和发展创新意识的重任。而反思是训练思维、优化思维品质的极好方法．是创造思维发生的必要条件。因此，引导学生学会反思，养成积极反思的习惯，可以有效地提高学生的思维能力，进而培养学生的创新意识和创造能力，提高学习能力。     

初中数学教学中学生创新能力的培养

数学教学是数学活动的教学，即思维活动的教学。如何在数学教学中培养学生的思维能力、创新能力，使学生具有初步的创新精神和实践能力是数学教学改革的一个重要课题。     

刍议数学教学活动中的创新

在数学教学活动中创新是当今教学的发展趋势。结合自己的教学实践，从学生的动手操作和课外活动两方面谈一谈如何培养学生的创新意识、创新思维、创新能力，从而达到全面提高学生数学素质的目的。     

浅谈创新精神在数学教学中的应用

数学教学的本质是数学思维活动的教学,培养学生的数学创新意识,必须让学生积极地展开思维,主动地参与教学过程。在数学教学中,教师要不断更新教学观念,吸收新知识,运用新方法,只有这样,创新教育思想才能生根开花,结出硕果。     

如何在数学教学中培养学生的创新意识

数学是一门思维性极强的基础学科，在培养学生的创新思维方面有着得天独厚的条件，但长期以来，我国的数学教学大都是“课堂为中心，书本为中心，教师为中心”单一模式，这样的方法不利于培养学侉的创新品质。要改变这样状况，数学教学必须突破传统的人际关系     

关于“数学问题解决”教学策略的几点思考

正确理解“数学问题解决”的教育观念是运用“数学问题解决”教学策略的前提，数学教学中应引导学生通过数学问题解决的学习方式构建数学知识，发展高层次的数学思维水平，激发创新意识，提高创新能力和内化创新精神。为了实现数学问题解决的教学策略应当紧紧围绕教学内容与教学过程进行开放性设计，充分运用现代信息技术，并通过反思指导不断提高数学问题解决教学的质量和效率。     

Markedness and its Interpretation in Language Use

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

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.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.

低渗透非均质砂岩油藏启动压力梯度研究

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。     

On Tragic Consciousness In The Works By Ernest Hemingway

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.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

An Index mechanism for multi-scale view in spatial databases

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.
