马克思主义的科学性已是国内学界的共识,但对“科学性”的界定却不甚了了,导致马克思主义研究中的学理性、真理性、规律性等范畴被“空泛化”。科学性在于它的系统性,对马克思主义科学性的把握需要从系统科学的维度加以辨识和理解。据此,从系统科学与马克思主义之间的思想关联来讨论马克思主义的科学性范畴:马克思对“科学”的理解从来都不等同于自然科学,也不是思辨的哲学体系。他从一开始就致力于在实践中将自然科学和哲学结合在一起,从而解决现实的人的问题。马克思的“科学”实际上是统一的科学,其形式必然呈现出系统科学的特征。将马克思主义科学性纳入系统科学视界,也许也是系统科学发展的新契机。

Abnormal Phenomena of Volume Strain before Large Earthquakes

Earthquake Research in China 2015年第3期29卷 373-385页

作者： Wu Lijun Chen Zhengwei Li Hangu Xu Lei An bayaer Xu Shunqiang Institute of Earthquake Science China Earthquake Administration Key Laboratory of Earthquake Prediction Institute of Earthquake ScienceCEA Wudi Dashan Seismic Station Earthquake Administration of Shandong Province Seismological Bureau of Weihai City Geophysical Exploration Center CEA

This paper studies the imminent anomalies observed by the Sacks volume strainmeter in Erzhangying station and Tiantanghe station before 80 earthquakes with Ms≥ 7. 0 which took place from January 2011 to April 2014 all over the world. Then, preconditions for anomaly identification are put forward for complex earthquake cases. Statistical results show that volume strain observation has a better earthquake reflecting ability for earthquakes with magnitudes larger than 7. 0 and epicentral distance within 8000kin. In addition, these results also reflect that the volume strain observation can better reflect precursory anomalies of such earthquakes. Based on categorization and description of those anomalies, we divide the anomalies into three types, that is, earth tide distortion type, abrupt change type and slow earthquake type. Furthermore, the paper makes a statistical analysis of these types and preliminarily discusses their mechanical properties as well. According to research, volume strain anomaly has an indicative significance to future strong earthquakes in the world.

Non-adiabatic quantum dynamical studies of Na(3p) + HD(v = 1, j5) = 0)→NaH/NaD + D/H reaction

Chinese Physics B 2019年第6期28卷 169-175页

作者： Yue-Pei Wen bayaer Buren Mao-Du Chen Key Laboratory of Materials Modification by Laser Electronand Ion Beams(Ministry of Education)School of PhysicsDalian University of TechnologyDalian 116024China

Non-adiabatic dynamical calculations are carried out for the Na(3 p)+HD(ν = 1, j = 0)→NaH/NaD+D/H reaction on the diabatic potential energy surfaces of Wang et al.(Sci. Rep. 2018, 8, 17960) by using the time-dependent wave packet method. The state-to-state integral cross sections and differential cross sections of two reaction channels(NaH/NaD+D/H)are calculated for collision energy up to 0.4 eV. The cross section branching ratio indicates that the dominant reaction channel changes from NaD+H to NaH+D when the collision energy is larger than 0.227 eV. The products from two reaction channels both prefer to form in vibrationally cold but rotationally hot states, and they both tend to forward scattering.

Target Tracking Based on SE-CNN and SiameseNet

Target Tracking Based on SE-CNN and SiameseNet

第三十九届中国控制会议

作者： bayaer Saiyin Wenjie Chen School of Automation Beijing Institute of Technology Beijing Institute of Technology Chongqing Innovation Center

Recently, Siamese convolution neural networks have achieved remarkable results in the field of target tracking because of their balanced accuracy and speed. At the same time, Siamese convolution neural networks can solve the problem that the deep neural network can’t be updated in time and training data is insufficient. We propose an object tracking algorithm based on SE-CNN and Siamese convolution neural network. SE-CNN is added to the feature extraction submodule of SiameseRPN convolution neural network to enhance the quality of spatial encodings. During inference,a novel distractor-aware objective module is introduced to perform incremental learning. Benefit from the SE-CNN and distractor-aware objective module,Our algorithm performs well in the terms of accuracy and robustness in VOT2015,VOT2016,VOT2017 and OTB 2015.

Non-adiabatic Couplings Induced Complex-Forming Mechanism in H+MgH^(+)→Mg^(+)+H_(2) Reaction

引用

Chinese Journal of Chemical Physics 2022年第2期35卷 345-352,I0003页

作者： bayaer Buren Ye Mao Zijiang Yang Maodu Chen Key Laboratory of Materials Modification by Laser Electronand Ion Beams(Ministry of Education)School of PhysicsDalian University of TechnologyDalian 116024China

A chemical process may involve multiple adiabatic electronic states, and non-adiabatic couplings play an important role in the reaction mechanism. In this work, the effect of non-adiabatic couplings in the H+MgH;→Mg;+H;reaction are studied using the time-dependent wave packet method and trajectory surface hopping method. The calculated results show that the reaction follows a direct abstraction process when the non-adiabatic couplings are neglected. However, when non-adiabatic couplings are included in the calculations, a longlived excited state complex(MgH_(2)+)*can be formed during the reaction. These direct and complex-forming reaction pathways are revealed by trajectory surface hopping *** non-adiabatic couplings induced complex-forming mechanism not only increases the reactivity but also has significant effect on the product vibrational state distribution.

村级规划是现行土地利用规划的延伸和完善,全面揭示村域土地利用结构特征是村级土地利用规划编制必不可少的前提条件。该文以四子王旗中部乌兰察布丘陵区西南8个乡镇54个村(社区)组成的典型的脆弱草原带农牧交错区为研究区域,以其所辖村(社区)为分析单元,利用2013年遥感影像解译数据,运用计量地理方法和GIS技术,定量分析村域土地利用结构特征,为脆弱草原带农牧交错区村级土地利用规划的编制提供参考依据。结果表明:研究区土地利用多样化指数平均值为0.71,所辖各村(社区)多样化指数介于0~0.77之间,土地利用类型多样化程度总体处于中等偏上水平;各村(社区)集中化指数介于-0.33~1之间,集中化程度总体呈现为中等偏下的状态;土地组合类型相对较丰富,半数以上的村(社区)地类组合类型以耕地-林地-牧草地为主,37%的村(社区)以耕地-林地为主,空间分布上基本形成了一个集最单一和最齐全组合类型的中心区域和以此为中心的3条南北带状分布区域及最外侧对称分布的2个地段,在这些不同区域和地段内耕地、林地和牧草地呈现出相间分布的特点;土地利用程度综合指数平均值为243.05,各村(社区)综合指数值介于213.83~400之间,土地利用程度总体水平较高;受地形、海拔及人类生产投入水平的影响,各类用地在各村(社区)的区位意义不尽相同,其中耕地和林地区位意义相对较突出,而对半干旱草原地区来说,牧草地区位意义并不突出。据此,脆弱草原带农牧交错区的土地利用,在完善灌丛林生态体系的同时加强牧草地保护和农田基本建设是确保草原生态安全和经济稳定发展的必然选择。

决策树算法是一种非参数化、非线性的监督分类法。以2010年8月1日Landsat TM影像为基础遥感信息源,以内蒙古自治区赤峰市中部巴林右旗、林西县、克什克腾旗、翁牛特旗交汇处的区域为研究区,通过多次修改完善训练样本数据集,然后把6个原始波段和NDVI、主成分分析后的前3个主分量、常用8个纹理特征以及3个地形特征等共21个特征变量组合成5个不同特征变量组合,采用典型决策树算法C5.0进行了遥感影像分类实验,与最大似然分类结果进行对比。结果表明:C5.0决策树的分类结果优于最大似然结果,尤其是特征变量组合恰当的时候,能够有效利用相关辅助信息,因而最终的分类结果更能满足用户需求。
