Formation environment and hydrocarbon potential of the Paleogene Enping Formation coal measures in the ZhuⅠDepression of northern South China Sea

The coal-measure source rock in the Chinese sea area plays a significant role as a hydrocarbon source rock,with its genetic environment,development and distribution,and hydrocarbon generation potential serving as essential factors for the exploration of coal-type oil and gas fields.This study focuses on the coal-measure source rock of the Paleogene Enping Formation in the ZhuⅠDepression,located in the northern South China Sea.The main geological insights obtained are as follows.The coal measures of the Enping Formation are developed in a warm and wet tropical-subtropical climate.The development environment of the coal-measure source rock in the Enping Formation includes the braided river delta upper plain peat swamp,characterized by dry forest swamp coal facies with relatively thick coal seams and a small number of layers.The braided river delta lower plain swamp-interdistributary bay of braided river delta front represents a forest edge-wetland herbaceous swamp coal facies with numerous layers of thin coal seams and poor stability.The shore swamp corresponds to an open water swamp coal facies with multiple layers of thin coal seams and poor stability.The organic matter abundance in the braided river delta upper plain is the highest,followed by the braided river delta lower plain-braided river delta front,and the shore-shallow lake.The organic matter type is predominantly typeⅡ1.Thermal evolution analysis suggests that the organic matter has progressed into a substantial oil generation stage.The hydrocarbon generation potential of the coal-measure source rock in the Enping Formation is the highest in the braided river delta upper plain,followed by the braided river delta lower plain-braided river delta front and the shore-shallow lake.Overall,this study proposes three organic facies in the coal-measure source rock of the Enping Formation:upper-plain swamp-dry forest swamp facies,lower plain-interdistributary bay-forest-herbaceous swamp facies,and lake swamp-herbaceous swamp facies.

Examining Zhang Peiji’s Translation of Beiying:A Study on the Representation of Zhu Ziqing’s Linguistic Style

Based on Yan Fu’s translation norms of“faithfulness,expressiveness,and elegance”and Liu Miqing’s concept of aesthetic representation in translation,the present study employed a combined method of qualitative and quantitative analysis to investigate the linguistic styles employed by Zhu Ziqing in his renowned prose Beiying.Then,using relevant corpora and self-designed Python software,we investigated whether Zhang Peiji,as a translator,has successfully reproduced the simplistic,emotional,and realistic linguistic characteristics in Zhu Ziqing’s prose from the perspectives of“faithfulness,expressiveness,and elegance.”The findings of the research indicate that by employing a dynamic imitative translation approach,Zhang Peiji has successfully enhanced the linguistic aesthetic qualities of the source text,striving to reflect the distinctive linguistic style of Zhu Ziqing.

Characterization of Hydroxyapatite Extracted from Crab Shell Using the Hydrothermal Method with Varying Holding Times

Hydroxyapatite(HA)is a bio ceramic commonly utilized in bone tissue engineering due to its bioactive and osteoconductive properties.Crab shells are usually disregarded as waste material despite their significant CaCO_(3) content,and have not been widely utilized in the synthesis of HA.This study aims to synthesize and analyze HA derived from crab shells using the hydrothermal method with different durations of holding time.This study utilized precipitated calcium carbonate(PCC)derived from crab shells.With a hydrothermal reactor set at 160°C and varying holding times of 14(HA_14),16(HA_16),and 18(HA_18)h,a PCC and(NH4)2HPO4 mixture was used to synthesize HA.The synthesis results were analyzed using scanning electron microscopy(SEM),fourier transform infrared spectroscopy(FTIR),and X-ray diffraction(XRD)tests.This study has accomplished the synthesis of HA from crab shells.Nonetheless,the final product of synthesis still contained CaCO_(3) as an impurity.The prolonged hydrothermal holding time of 14 to 18 h resulted in a reduction of impurities while increasing the percentage of crystal weight and crystallite size of HA.Specimen CH_18 is the best-quality product generated in this study.This specimen produced HA with the highest percentage of crystal weight and crystallite size compared to the other specimens.Furthermore,specimen CH_18 exhibited the lowest concentration of impurities.The Ca/P ratio in this specimen was also the closest to 1.67.The Ca/P ratio,crystallite size,and crystal weight percentage of this specimen are 1.54,19.06 nm,and 99.1%,respectively.

Differences of tuffaceous components dissolution and their impact on physical properties in sandstone reservoirs: A case study on Paleogene Wenchang Formation in Huizhou-Lufeng area, Zhu I Depression, Pearl River Mouth Basin, China

The element geochemical characteristics and diagenetic alteration products of tuffaceous components in sandstone reservoirs of Paleogene Wenchang Formation in typical subsags of the Huizhou-Lufeng area of the Zhu I Depression,Pearl River Mouth Basin,were identified through microscopic analysis and quantitative analysis of main and trace elements.The impacts of dissolution of different tuffaceous components on physical properties of reservoirs were discussed through quantitative characterization of reservoir physical properties.The results show that there are mainly four types of tuffaceous components in the study area,which are acidic,intermediate,basic and alkaline tuffaceous components.The acidic tuffaceous components evolved in a process of strong alteration and weak dissolution of alteration products,with a large amount of kaolinite precipitated during alteration to disenable the improvement of porosity and permeability.The intermediate and alkaline tuffaceous components evolved in a process of strong dissolution of tuffaceous components and strong alteration of residual tuffaceous components;the dissolution of tuffaceous components created intergranular pores,but the alteration products such as autogenic quartz,apatite and illite deteriorated the pore structure;ultimately,the dissolution of tuffaceous components resulted in the increase of porosity but no increase of permeability of the reservoir.The basic tuffaceous components dominantly evolved in a process of dissolution of tuffaceous components to strong dissolution of alteration products;both tuffaceous components between particles and laumontite generated from alteration can be strongly dissolved to create pores;thus,the dissolution of tuffaceous components can significantly increase the physical properties of the reservoir.

Nail Holding Performance of Self-Tapping Screws on Masson Pine and Chinese Fir Dimension Lumbers

Screw connection is a type most commonly applied to timber structures.As important commercial tree species in China,Masson pine and Chinese fir have the potential to prepare wood structures.In this study,the effects of the diameter of the self-tapping screw and the guiding bores on the nail holding performance on different sections of Masson pine and Chinese fir dimension lumbers were mainly explored.The results showed that:(1)The nail holding strength of the tangential section was the maximum,followed by that of the radial section,and that of the cross section was the minimum.(2)The nail holding strength of Masson pine was higher than that of Chinese fir.(3)The nail holding strength grew with the increase in the diameter of self-tapping screws,but a large diameter would lead to plastic cracking of the timber,thus further affecting the nail holding strength.Masson pine and Chinese fir reached the maximum nail holding strength when the diameter of self-tapping screws was 3.5 mm.(4)Under a large diameter of screws,prefabricated guiding bores could mitigate timber cracking and improve its nail holding strength.(5)Prefabricated guiding bores were more necessary for the screw connection of Masson pine.The results obtained could provide a scientific basis for the screw connection design of Masson pine and Chinese fir timber structures.

Continuity and Change in Dao Yin:Comparing and Contrasting the Therapeutic Exercises in Yin Shu(The Book of Pulling,c.2nd Century BCE)and Zhu Bing Yuan Hou Lun(Treatise on the Origins and Manifestations of Various Diseases,610 CE)

The manuscript Yin Shu(The Book of Pulling),excavated from Zhangjiashan Han Tomb No.247,is the earliest surviving text on therapeutic exercise known as Dao Yin(lit.guiding and pulling).Discovered in 1983,this Dao Yin text,together with the drawings of 44 figures performing“guiding and pulling”exercises found in the Mawangdui Han Tomb in 1974,are of great significance to the study of the early history of Dao Yin.Prior to these discoveries,researchers into Dao Yin relied mainly on material found in the Dao Zang(the Daoist Canon),compiled in 1145.This led to their conclusion that Dao Yin was essentially Daoist.The development of Dao Yin reached its zenith during the Sui Dynasty(581–618 CE),when it became one of the three medical departments at the imperial medical education institution.As part of the medical reform of the second Sui Emperor,Yang Di,Dao Yin became the treatment of choice,and the employment of a large number of Dao Yin specialists to the Sui court transformed the state medical service.The compilation of Zhu Bing Yuan Hou Lun(Treatise on the Origins and Manifestations of Various Diseases)under Yang Di’s decree,incorporated an abundance of resources on Dao Yin,enabling physicians to potentially“prescribe”Dao Yin to their patients.Situating both Yin Shu and Zhu Bing Yuan Hou Lun in their social and historical contexts,this article analyses their editorial treatments,examines their different objectives,styles,and readerships,and compares the various exercises described in the two texts.It emphasizes the fact that over a period of nearly a thousand years,from the late Warring States(475–221 BCE)to the Sui and Tang periods,Dao Yin was an important medical practice,culminating in its institutionalization by the Sui government.

The Topological Deformation of Brave Female Images in Shakespeare’s Plays:A Case Study of Juliet,Portia and Cordelia in Zhu Shenghao’s Translation

The female images in Shakespeare’s plays are diverse and colorful,showing the typological deformation value of topology.The brave female women in his plays,such as Juliet in Romeo and Juliet,Portia in The Merchant of Venice,Cordelia in King Lear,are the same type and equivalent topological deformation.In artistic terms,the three women of the same type with their own characteristics are the deformed topological space under the principle of equivalence,which is embodied vividly in the source text.This thesis purposed to investigate whether the translation of Zhu Shenghao also reflected the equivalent deformation of Shakespeare’s original text.This study texts the validity of the target text from the source text,proves the evaluation mechanism and function of topology in the process of translation and explains how the translation is equivalent to the original.

数据资源持有权的法律解释

在大数据和人工智能技术的推动下,数据资源从单纯的信息载体转变为独立的价值来源,开始出现财产属性。但其所具有的非排他性、技术依附性等特征使得传统的信息权益与权利保护范式难以适用。数据资源的价值源于对数据的控制状态,这并非实体权利。数据资源持有权在法律上应解释为“持有主体合法控制数据资源并免受非法干扰和攻击的利益”。持有利益受侵害所造成的损失属于纯粹经济损失,应采用行为主义保护模式,通过侵权法一般条款进行救济。持有主体则应根据具体数据类型遵守相应的行为标准。此外,个人信息数据的相关规则是基于风险防范的考量,对数据所携带信息采取保护措施,个人信息主体属于数据来源者而非数据资源持有主体。

数字经济与新型城镇化:作用机制和门槛效应

随着新一代信息技术蓬勃发展,数字经济无疑是实现新型城镇化的必然选择。本文基于2013~2022年30个省(区、市)的面板数据,通过构造数字经济发展水平指数与新型城镇化水平指数研究数字经济对新型城镇化的影响,并引入技术创新和碳减排分析数字经济驱动新型城镇化的作用机制。研究发现,数字经济对我国新型城镇化的建设具有明显的推动作用,在新型城镇化水平低的省(区、市)与中部地区提升效果更明显;机制分析表明,技术创新和碳减排是数字经济促进新型城镇化的重要传导机制;通过进一步的门槛检验发现,数字经济对新型城镇化的推动作用因产业结构的不断升级呈现出先正后负的特征。研究结论可为加速释放数字经济红利,推动新型城镇化发展提供经验证据和政策启示。

“数据二十条”下探析数据资源持有权的内涵及框架构建

《关于构建数据基础制度更好发挥数据要素作用的意见》(简称“数据二十条”)提出了以“数据流通激励”为主旨的数据产权结构性分置制度。对数据资源持有权的合理配置影响到数据利益的第一次分配,是实现数据“共同使用、共享收益”的战略性目标的基础。基于传统排他性产权思维下的数据资源持有权分配模式,皆存在加剧数据共同生产者之间利益冲突的可能性。本文提出在数据生产者之间以“1+N”模式配置数据持有权,即“特定数据生产者的在先持有权+N个其他数据生产者的访问权”模式,通过技术治理和透明度治理等工具的支持,探索符合数据经济发展规律的、公平的高效的新型数据产权制度。

在论诗与论理之间《:朱子语类》论诗的话语意义

《朱子语类》论诗有其独特面貌,朱熹有意选取语录体诗话的方式进行言说,着意呈现诗歌创作中面向生活审美的浑融气象,在论诗观念上体现出诗话语境下诗与理的互斥互塑,并在此基础上着力推崇豪壮诗风,体现出朱熹系统性的审美观念和话语策略。康德对崇高审美的分析将朱熹原本诉诸审美经验和直觉体悟的文本呈现进行理性化理解,合理解释了为何朱熹所推崇的豪壮诗风较之其他风格更能体现“近道气象”,更为具体地揭示出朱熹理想诗风的重要特点。《朱子语类》论诗不仅体现出朱熹不同于一般理学家的审美修养,更是系统地体现出他在审美层面对体道方式的根本性探索及其对此种话语方式之于体道意义的自觉。

朱熹论曾子——兼论朱熹的子学建构

曾子历史地位的升格,朱熹于此贡献最大。他系统论证了曾子的道统地位,认为在“十六字心法”之外,独属于孔、曾之间的道统之传为“忠恕一贯”,并有着实质性影响。在他的视域中,曾子资质“鲁钝”“刚毅”,实则仁义礼智兼备,其孝亦“大矣”。朱熹对曾子的讨论,主要是为了完整地确立曾子的圣贤人格形象和道统地位。综合来看,朱熹理学中理应存在一个子学系统,但基本为学界忽略。其子学体系的建构源于经学、子学、史学与哲学的互动,根本主旨在于对儒学道统、治统与学统的维护。

《画史会要》“朱谋垔托名说”辨误
