关中平原城市群城市资源集聚能力演变及其影响因素

探究城市资源集聚能力的变化趋势与影响因素,对优化资源空间配置,促进城市群高质量发展有重要意义。论文构建评价模型评价城市资源集聚能力,揭示2003—2020年关中平原城市群内部城市资源集聚能力时空演变特征,并通过空间计量方法估计影响城市资源集聚能力演变的影响因素。研究发现关中平原城市群内部资源集聚呈现“首位”分布,西安的资源集聚能力最大但增长缓慢,而其他城市资源集聚能力总体不高且大部分降低。城市资源集聚能力的空间分布在缓慢集中,且存在正向空间依赖。经济发展水平、生态环境质量、科技发展水平、公共服务水平和工资水平显著提升了城市资源集聚能力,而市场化水平抑制了城市资源集聚能力。

基于创新视角的上海科技型中小企业空间集聚研究

对上海科技型中小企业的空间集聚进行分析,得出研究结论:与上海的研发机构和高新技术企业的高度集聚不同,科技型中小企业在空间形态上具有"中心外围"的特点,外环以内是主要集聚区,远郊区县分布相对分散.集聚模式可分为两种类型,一种是依托高新技术园区、高等院校以及科研院所的科技型中小企业,主要属于开发功能优先型;另一种是依托所在区县的支柱产业的中小企业,这类企业广泛分布在各个区县,与所在区县的产业结构关联性较强,属于承接边际产品转移、市场指向型.     

等级化、网络化与区域化:基于律师事务所空间分布的中国城市体系研究

借鉴"全球化与世界城市研究网络"(Ga WC)所采用的方法,以6大生产性服务业之一的法律咨询服务(律师事务所)为指标,分析了中国排名前50位的律师事务所的总部及其分支机构在289个城市的空间分布.发现东部沿海地区城市和内陆省会城市的服务值以及连接度普遍较高,法律咨询服务在北京、上海、深圳等少数城市存在很强的集聚性,主要的法律服务机构分布在约20%的城市之中;同时这些城市之间存在明显的等级性,服务值分为4个等级,连接度分为5个等级.法律咨询服务在我国少数经济发达区域中的城市集聚,并且在本区域内城市间的相互联系很强,存在显著的区域性;在长三角、珠三角、京津冀、东北地区、山东半岛和福建东部沿海地区等区域已经形成了不同完善程度的区域城市网络结构.形成上述特性的主要原因是各城市的经济实力与特性、我国体制下的政治因素以及现阶段法律咨询服务机构在我国的空间扩张模式,类似于前人研究所揭示的美国的情况.

经济集聚对福建省城市土地产出率的影响研究

随着农村劳动力持续向城市集聚,城市规划用地供给日趋紧张,如何利用有限的土地资源提高福建省城市土地产出率是亟需研究的现实问题.本文把政府干预程度、经济结构和城市用地规模等指标融入生产函数,以此构建土地产出率的理论模型,并采用面板数据模型进行实证检验.实证分析结果表明:劳动力替代效应使得劳动力集聚与资本集聚相比对城市土地产出率的正向影响更强,但是劳动力过度集聚无法提升福建省城市土地产出率;劳动力的收入效应提高城市人力资本水平,进而提升福建省城市土地产出率;劳动力转移、土地供给扩张以及政府干预过度反而降低土地产出率.本文认为促进经济集聚、优化产业结构和合理利用土地等政策都有利于提高福建省城市土地产出率.     

上海创意产业园区空间集聚特征研究

运用聚类分析方法(Cluster Analysis)对上海创意产业园区空间集聚特征分批次进行了研究,并运用空间分析软件对分批次园区的集聚程度进行了判读.发现园区主要沿大学密集区、苏州河、内环线呈带状分布于浦西地区,且集聚分布趋势愈发明显.在此基础上,对上海创意产业园区的空间集聚特征的形成机制进行了探讨.认为其主要机制在于旧城改造的导向、中心区优势资源的吸引、旧工业建筑空间的指向和高校院所的互动等四方面的共同作用.     

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.     

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.

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.
