The visible-near-infrared spectra of air-dried soil samples were determined by ASD FieldSpec Pro hyperspectral spectrometer under indoor conditions. The changes of soil spectral reflectance curve shape and soil organic matter content under different soil depths and different vegetation cover were analyzed, and the loess was analyzed. The spectral reflectance of the soil in the Taihu area is transformed by the first derivative, the derivative of the reciprocal, the derivative of the logarithm, the derivative of the logarithm of the reciprocal and the derivative of the reciprocal of the logarithm, and the multivariate stepwise regression analysis with the soil organic matter content. Least Squares Regression Analysis (PLSR) was established based on the characteristic spectral segments to establish a multivariate stepwise regression model and a partial least squares regression model. The comprehensive analysis shows that the partial least squares method has more advantages in the study of soil organic matter content hyperspectral prediction.

威远基底结构与龙马溪组地层构造及沉积相关系研究
The Relationship Study between the Basement Structure and the Structure-Sedimentary Facies of Longmaxi Formation in Weiyuan Syncline  [PDF]
范宏娟, 刘殊
Advances in Geosciences (AG) , 2021, DOI: 10.12677/AG.2021.112010
Abstract: 威远向斜钻井揭示，龙马溪组I段为主力气藏，其页岩厚度、品质变化较大，与产能关系密切。沉积微相的研究是储层目标评价、气藏描述的关键。但用地震资料精细描述龙马溪组I段优质页岩分布，还有一定难度。为此，通过基底结构分析上覆地层构造、沉积微相变化规律，并分析其形成机理；采用单井旋回划分，结合地震反射结构识别，建立层序地层格架；综合构造、沉积相描述，预测龙马溪I段页岩气藏分布规律。研究表明：下震旦统发育一个大型的洼陷，东南侧发育一个大型的隆起；上覆地层的向斜和背斜，与下震旦统的洼陷－隆起正好对应。其次，威远向斜中部优质页岩厚度较大、品质优，正对下方古洼陷位置；龙马溪组2-3段在东南侧发育由东南向西北进积的斜交反射，正对下震旦统古隆起位置，页岩品质也相对较差。威远向斜的构造、沉积相明显受下震旦统古洼陷–隆起控制。下震旦统大型洼陷上方的志留系洼陷，预测为龙马溪组I段优质页岩、最佳气藏分布带。
In the Weiyuan syncline, the shale of I section of Longmaxi group is the main gas reservoir. The thickness and the quality of the shale changes greatly, which is closed to the capacity. The study of sedimentary microfacies is the key to evaluate the reservoir targets and to describe gas reservoirs. However, it is difficulty using seismic data to describe the shale’s distribution. The structure of overlying strata and sedimentary microfacies are analyzed by studying basement structure and its formation mechanism. The sequence stratigraphic framework is established by single well cycle and seismic reflection structure. The description of structure and the sedimentary facies is synthesized to predict the shale gas reservoir of Longmaxi group. The research shows that: a large depression develops in the Lower Sinian and a large uplift in the southeast. The syncline and anticline of the overlying strata correspond to the depression-uplift of the Lower Sinian. Secondly, the shale of Weiyuan syncline, which is of great thickness and high quality, directly faces the ancient depression. Section 2-3 of the Longmaxi Formation develops oblique reflections from southeast to northwest which is opposite to the ancient uplift of the Lower Sinian, and of relatively poor quality. In Weiyuan syncline, the tectonic and sedimentary facies are obviously controlled by lower Sinian depression-uplift. It is forecasted that the Silurian depression, which is at the top of the sub-sag of the lower Sinian, is the best shale’s gas reservoir distribution zone.
低自旋(S = 1/2)过渡金属配合物的慢磁弛豫

徐红娟, 刘泉
Hans Journal of Nanotechnology (NAT) , 2021, DOI: 10.12677/NAT.2021.113022
Abstract:
随着单离子磁体的蓬勃发展，研究人员发现即使当配合物的基态自旋为低自旋(S = 1/2)，仍可以表现慢磁弛豫行为。这类配合物在量子信息处理方面(QIP)方面具有较大的应用潜能，因此得到了众多研究者的关注。对于过渡金属配合物，配体的选择影响中心金属离子的电子结构，进而影响其慢磁弛豫行为及量子相干性质。本文结合近年来的研究成果，对低自旋配合物的慢磁弛豫行为进行了阐述，分析了其弛豫行为来源，并对弛豫机理进行总结，为量子比特的设计提供思路。
With the rapid development of single ion magnets, researchers found that a few of complexes even with low-spin (S = 1/2) ground state spin can still exhibit slow magnetic relaxation behavior. Owing to their great potential in quantum information processing (QIP), these complexes have attracted many researchers’ attention. For transition metal complexes, the ligands coordinating to the transition metals have great impact on the electronic structure of central metal ions, and then significantly affect the slow magnetic relaxation behavior and quantum coherence properties. Based on the recent research, this paper describes the slow magnetic relaxation behavior in low-spin complexes. Moreover, we have analyzed the origin of the relaxation behavior and summarized the relaxation mechanism in these complexes, which will provide new routes in the design of quantum qubit.
不含相邻短圈的平面图的点荫度问题
Vertex Arboricity Problem of Planar Graphs without Adjacent Short Cycles  [PDF]
刘星, 王慧娟
Pure Mathematics (PM) , 2021, DOI: 10.12677/PM.2021.118176
Abstract:
在社团网络的研究中，社团结构划分一直是一个有价值的研究课题。 出于安全考虑，对一个新的社团结构划分问题进行研究，它可以在图论中转化为最小化问题。 图G的点荫度是对G的点集进行顶点着色，使得每个颜色类的导出子图是G 的森林的最小颜色数，一般用符号va(G)表示。 一般地，对于任意平面图 G ，va(G) ≤ 3，且对任意非空图 G，va(G) ≥ 1 成立。 显然，va(G) = 1当且仅当图G 是一个无圈图。 对于某些特殊情况，如果图G是一个不含3-圈的平面图，va(G) ≤ 2。Raspaud 和Wang 等人证明了如果图G是一个不含4-圈或不含5-圈的平面图，则va(G) ≤ 2。 此外，Huang, Shui 和Wang 等人证明了如果图G是一个不含7-圈的平面图，则va(G) ≤ 2。 在本文中，我们证明了如果图G是一个不含相邻的3-圈和4-圈的平面图，或者不含相邻的4-圈和5-圈的平 面图，则va(G) ≤ 2。
In the research of social networks, social structure decomposition has always been a valuable research topic. For security reasons, we study a new social structure decomposition problem, which can be decomposed into a problem of minimization in graph theory. The vertex arboricity of a graph G, denoted by va(G), is the minimum number of subsets such that the vertices of G can be colored and every color class induces an acyclic graph such as a forest of G. Normally, va(G) ≤ 3 for every planar graph G and va(G) ≥ 1 for every nonempty graph G. There is no doubt that va(G) = 1 if and only if G is an acyclic graph. For some special cases, it is known that va(G) ≤ 2 if G is a planar graph without 3-cycles. Recently, Raspaud and Wang et al.？ proved that va(G) ≤ 2 if G is a planar graph without 4-cycles or without 5-cycles. In addition, Huang, Shiu, and Wang showed that if G is a planar graph without 7-cycles, then va(G) ≤ 2. In this paper, we prove that if G is a planar graph without adjacent 3-cycles and 5-cycles, or without adjacent 4-cycles and 5-cycles, then va(G) ≤ 2.
新时代大学生绿色消费行为培育路径研究
Research on the Cultivation Path of Green Consumption Behavior among College Students in the New Era  [PDF]
冯娟, 刘晓宇
Interdisciplinary Science Letters (ISL) , 2025, DOI: 10.12677/isl.2025.92017
Abstract: 在党的二十大报告中，习近平总书记明确强调：“要加快发展方式绿色转型，倡导绿色消费，推动形成绿色低碳的生活方式和生产方式。”随着经济的蓬勃发展和人民生活水平的普遍提升，消费活动日益频繁，而在这股消费浪潮中，部分大学生出现了诸如炫耀性消费、超前消费等非理性消费行为。这些不良的消费习惯与模式，不仅对大学生个人的健康成长构成威胁，也与绿色消费观的培育目标背道而驰。因此，为了有效引导大学生践行绿色消费理念，需要大学生自身、家庭、高校的共同努力。
In the report of the 20th National Congress of the Communist Party of China, General Secretary Xi Jinping emphasized the need to accelerate the green transformation of development mode, advocate green consumption, and promote the formation of green and low-carbon lifestyles and production modes. With the vigorous development of the economy and the general improvement of people’s living standards, consumption activities have become increasingly frequent. In this wave of consumption, some college students have exhibited irrational consumption behaviors such as conspicuous consumption and advanced consumption. These unhealthy consumption habits and patterns not only pose a threat to the personal healthy growth of college students but also go against the goal of cultivating a green consumption concept. Therefore, to effectively guide college students to practice the concept of green consumption, it requires the joint efforts of college students themselves, their families, and universities.

This paper mainly focuses on the gray-scale ultrasound breast tumor images. According to the characteristics of ultrasonic image and shortcomings of the P-M model, a modified P-M model filter with local information and spread threshold is proposed. All common pretreatment algorithms are put into experiments and a comparison is made among them. The results show that the modified P-M model filter can more effectively remove the speckle noise.
