The Changbai Mountains, located in northeastern China, show clear vertical zonation of vegetation types. Six different habitats,namely Pinus koraiensis mixed broad-leaved forest, Pinus koraiensis-Picea forest, spruce-fir forest, Betula ermanii forest, alpine meadow and alpine semi-desert, at elevations ranging from 780 to 2 480 m, covering almost all ecosystems on the north slope of the Changbai Mountains, were investigated to determine: i) whether or not the community composition of soil mesofauna varied significantly at different elevations; ii) if different soil mesofauna groups would respond differently to elevation and iii) which factors influenced the spatial distribution of soil mesofauna along elevation. Soil mesofauna were collected from each habitat in spring(May),summer(July) and autumn(September) of 2009. The soil mesofauna communities were comprised of at least 44 groups and were dominated by Acari and Collembola, followed by Coleoptera, Diptera larvae and Enchytraeidae. The composition, diversity and abundance of soil mesofauna varied among the six habitats. Meanwhile, significant seasonal variations were observed in the composition,abundance and diversity of the soil mesofauna in each habitat. The taxonomic richness and Shannon index were affected by elevation and soil properties, while the abundance was only significantly affected by soil properties. With regard to taxa, the habitats and seasons had significant effects on almost all the abundances of the major taxonomic groups. The abundance of more taxonomic groups was significantly influenced by the soil properties, while those of Geophilomorpha, Araneae and other taxa were affected by *** is concluded that the composition and spatial distribution of the soil mesofauna varied along the elevation gradient on the north slope of the Changbai Mountains, which might be largely related to the variations of the plant community, soil properties and climate change resulting from the elevation gradi

Eye Science 1996年第3期16卷 138-139页

作者： fubin wang, Tao Chu, Wei ZhangDepartment of Ophthalmology, the First Affiliated Hospital of Qiqihar Medical College Qiqihar 161041, China Department of Ophthalmology First Affiliated Hospital of Qiqihar Medical College China.

Purpose: To study the refractive changes of form deprivation of myopia. Methods: Haisaik chickens were used to establish the animal models of myopia. Monocular eyelids were sutured for form deprivation on the 5th day after chickens birth. The chickens were examined by optometer and the anteroposterior axis, transverse and vertical diameters were measured by verniermicrometer. Results: Form deprivation leads to myopic refractive abnormality (P<0. 001). The ocular anteroposterior axis (P<0. 005), transverse and vertical diameters lengthen (P<0. 05).Conclusion: Form deprivation is the main cause of the development of myopia.

Cratonic Strike-Slip Faults in the Southwest Ordos Basin(Central China)， and Their Influence on Hydrocarbon Accumulation

Journal of Earth Science 2024年

Cratonic strike-slip fault， despite its potentially significant influence on hydrocarbon accumulation， has attracted limited attention. This study investigates the geometry and kinematics of the cratonic strike-slip faults newly identified within the southwest Ordos Basin， Central China， based on 3D seismic reflection data. We recognized three dominant sets of faults with strike-slip nature trending respectively in NW， ENE， and N–S directions in the study area. These faults exhibit a stratified style characterized by distinct trends across various strata， with ENE-trending faults in the Mesozoic strata (Area A)， N-S-trending faults in the Paleozoic strata， and vertically discontinuous structures in the Mesozoic and Paleozoic strata (NW-trending Yudu fault zone and ENE-trending Yulinzi and Zaosheng fault zones). The contrasting kinematics of strike-slip faults observed in deep and shallow layers further confirm such fault stratification， suggesting isolated fault evolution within respective layers. The quantified fault parameters obtained from seismic reflection data， including length， width and displacement， suggest that these cratonic strike-slip faults in the Ordos Basin are immature. Comparisons with strike-slip faults in other cratonic basins and active tectonic settings suggest that the strike-slip faults within the Ordos Basin are representative of cratonic strike-slip faults， characterized by low maturity and a stratified faulting style， and they have special propagation mechanism (preferentially occurring in the shallow strata of the interior of the basin). Moreover， these fault characteristics have dual impacts on petroleum accumulation in the southwest Ordos Basin. The low faulty maturity makes the fault zone a special hydrocarbon reservoir (fault-fracture volume) in tight sandstone， while the stratified faulting style vertically separates the Mesozoic and Paleozoic petroleum systems in the southwest Ordos Basin. Our findings therefore contribute significa

烧结机尾断面火焰图像能够最直接有效地反映烧结终点的状态。充分利用火焰断面图像所蕴含的有效信息对烧结终点状态进行分类具有可行性及工程实际意义。提出一种K均值结合图像颜色特征的分类算法,实现对烧结机尾断面火焰烧结状态的分类。首先,对90张火焰图像进行预处理,在烧结机采集的320 m2断面图像上按分辨率3024×1700像素对红火区域进行统一裁剪,提取烧结核心区域。对裁剪图像进行K均值分割,并对K分别为2,3,4的分割图像进行比较,结果表明K为3时的分割结果可以较准确地将火焰的红火区分割出来。其次,由于分割后的图像仍存在其他非红火区域,为了准确地提取红火区的几何特征,进一步对红火区进行颜色特征提取,得到最终的红火目标区域分割图像。最后,将提取的目标图像几何特征作为数据集,采用fuzzy C-means(FCM)算法对烧结终点状态进行分类。与传统FCM算法的分类结果对比表明,所提火焰图像分类算法改善了分类效果。

为使基于产品平台的系列产品更好的满足顾客需求,提出一种基于质量功能展开的方法,可以优化设计可伸缩产品平台。该方法的主要思路是应用质量功能展开技术,建立单个产品的质量屋,确定其最优工程特性值,对每个工程特性进行敏感性分析,并根据所得的工程特性敏感性指标建立优化模型,求得最优的平台工程特性值和非平台工程特性值。优化模型的目标是最大化一个产品族中所有产品变体的顾客满意度的均值,约束主要包括顾客需求和工程特性之间的函数关系以及工程特性之间的自相关函数关系。模型中采用了线性函数形式,并采用回归方法来估计函数中的参数。给出一个工业卡钳的例子来验证所提方法的可行性,案例分析的结果表明,该方法比传统的两阶段方法能获得更好的顾客满意度。

飞秒激光在微加工过程中衍生的等离子体亮度特征可作为实时反馈的测量信号,因此,研究光斑亮度特征并构造细节信息丰富的高质量亮度变化曲线具有重要意义。首先,针对光斑图像信噪比低、目标区域边缘模糊的情况,采用改进的小波阈值去噪法对光斑图像进行滤波处理,在不改变光斑亮度水平的情况下得到边缘对比度较高的平滑光斑。然后,采用K均值聚类方法分割光斑图像,将表现为噪声的光晕部分分割出去,只保留亮度有效的区域。最后,提取光斑序列图像的亮度变化曲线,用分形与多尺度软阈值滤波相结合的方法对曲线进行处理,得到含有丰富细节信息的高质量亮度变化曲线。用不同功率的光斑图像计算亮度与分形维数,结果表明,光斑亮度和光斑变换的复杂性均随激光加工功率的增大而增大。
