待发表的部分论文摘要预告

为了消除地表水对矿坑水的影响，节约投资，在矿区地表水防治工程中需要确切知道浅部岩溶发育带的位置。带着这一观点，作者在桥头河矿区存在问题较严重的几个地段进行了天然电场探测，划分出16个异常带，取得较好的效果，值得进一步探讨和推广。

在概述研究区的水文地质条件的基础上,分析了贵州水银洞金矿矿区充水因素,并采用集中参数法对矿区涌水量进行了预测.研究表明,下覆茅口组含水层中的地下水是矿区巷道的直接补给源,地表水和降水为间接补给源;最终矿坑涌水量预测为41 904 m3/d.     

徐州大屯矿区矿井水影响下地表水微量元素污染及土壤碱化潜势分析

采集徐州-大屯矿区的地表水、矿井排出水与灰岩水,测试了主要有害微量元素的浓度,并通过[Na~+],[Ca~(2+)],[Mg~(2+)]计算了钠吸附比。发现矿井水中微量元素含量高于地表水,按照国家水质标准属于五类或劣五类水。矿区地表水中微量元素浓度虽未超标,但矿区的地表水高于非矿区的地表水,说明矿井水对地表水造成了一定的影响,这种影响可能影响到水体,底泥,以及土壤。从灌溉的角度来看,矿井水的钠吸附比较高,距离矿井水排放处近的地区,可能受到的影响较大。另一方面,煤层顶板淋滤水的钠吸附比比煤层淋滤水的高,原因在于煤层顶底板中粘土矿物的离子交换吸附,从而对土壤的影响也较大。     

弓长岭铁矿一矿区构造演化分析

弓长岭铁矿包括一、二、三矿区和老岭-独木矿区,其中一矿区是目前弓矿公司最大的露天采区,已进入危机矿山行列,因此,开展弓长岭铁矿一矿区的构造演化研究,理清弓长岭铁矿一矿区构造控矿规律,对于弓长岭铁矿一矿区深部及外围找矿分析具有较大的借鉴意义。研究表明:随着寒岭断裂的走滑运动,在弓长岭铁矿南盘左部出现了一个相对伸展区,右侧出现了一个相对压缩区。然后使得弓长岭矿带整体以软弱点为中心的逆时针旋转。在旋转的同时,弓长岭矿带被略微的拉长。在整个变形过程中,矿带尾端的转折端形成了第二软弱点。随着寒岭走滑运动的消减,弓长岭矿带开始沿着前期形成的断裂发生走滑,最终把弓长岭矿段改造成一大两小三个反"S"型,最终将弓长岭切割为3个矿区:弓长岭一号矿区、二号矿区、三号矿区。     

隘头煤矿区矿井充水因素分析

通过矿区调查、勘探，分析矿区水文地质条件、地表水及地下水动态特征及开拓井巷所反映的矿井水文地质情况，我们认为在正常情况下，隘头煤矿区直接充水含水层对煤层开采不构成直接威胁，浅部煤层开采时局部与第四系孔隙水以及地表水会有直接的水力联系，隘头煤矿区灰岩含水层和老窑积水是矿山安全生产的主要防范对象。

疏勒河干流地表水与地下水水化学特征及相互转化关系

文章在分析疏勒河干流地表水与地下水水化学特征的基础上,识别了疏勒河干流不同地带地表水与地下水的补排关系。分析结果认为:(1)祁连山区,地下水与地表水的转化以地下水向河流排泄为主;(2)南盆地,在山前洪积扇出山河水入渗转化为地下水;溢出带地下水以泉的形式转化为地表水;在农灌区引河水通过田间入渗补给地下水;(3)北盆地双塔灌区,地下水主要接受引水灌溉入渗补给,沿途蒸发排泄并向地势低洼地带排泄。

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.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

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.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

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。

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

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.
