The main purpose of this paper is to establish a type of quantitative model by using the contangent similarity function in the three-valued?ukasiewicz propositional logic system ?;. We introduce the concepts of the cotangent similarity degree, cotangent pseudo-distance and cotangent truth degree of the propositions, together with their basic properties in ?;.We investigate the relationship between the cotangent truth degree and contangent pseudo-distance, and prove the continuity of the logical connectives ?, ∨ and → in the ?;logical metric space. We propose a graded reduction method and three types of graded reasoning frameworks on the propositions set F（S）, and provide several examples and basic properties of it.

Coupling effects among different physical fields reflect the conversion of energies from one field into another *** simple physical processes,their governing or constitutive equations all satisfy the law of conservation of energy(LCE).Then,an analysis is extended to the coupling ***,for the linear direct and converse piezoelectric and piezomagnetic effects,their constitutive equations guarantee that the total energy is conserved during the process of energy conversion between the elastic and electromagnetic ***,the energies are converted via the work terms,(βijkEi),kvj and(γijkHi),kvj,rather than via the energy terms,βijkEiejk andγ***,for the generalized Villari effects,the electromagnetic energy can be treated as an extra contribution to the generalized elastic ***,for electrostriction and magnetostriction,both effects are induced by the Maxwell ***,their energies are purely electromagnetic and thus both have no converse *** these processes,the energies can be converted in three different ways,i.e.,via the non-potential forces,via the cross-dependence of the energy terms,and directly via the electromagnetic interactions of ions and *** the end,the general coupling processes which involve elastic,electromagnetic fields and diffusion are also *** advantages of using this energy formulation are that it facilitates discussion of the conversion of energies and provides better physical insights into the mechanisms of these coupling effects.

ChatGPT的持续爆火再次引起人们对人工智能影响问题的普遍关注。系统研究和评估ChatGPT对民主的影响具有理论和现实的双重意义。ChatGPT是人工智能技术发展新的里程碑,同样是一把双刃剑,其技术扩散嵌入政治领域是影响民主的逻辑起点。ChatGPT既有民主共治、共享、共商、共建的机遇和潜能,也有民主困境、失效、危机、异化、治理和话语权的挑战与风险。ChatGPT通过技术操控侵蚀民主、影响西方民主实施过程,通过话术游说影响民主决策及立法公正性,通过加深数字鸿沟削弱民主治理能力,通过话语权垄断维护西式民主话语霸权。我国要抓住机遇、迎接挑战,在价值设计、政党治理、社会治理、技术治理、素养提升等多个层面,建立和完善针对性的新型多元民主治理体系,用最新科技武装全过程人民民主的实践。

背景:微循环作为人体物质能量代谢交换的唯一场所,与人体运动能力密切相关。抗阻运动是提高微循环功能的有效方式,但也有研究指出血流限制训练也能提高微循环功能,且具有负荷小和安全性高等优点。目的:比较6周低负荷血流限制运动、高强度抗阻运动对运动型男性青年大腿微循环功能的影响,并从血管内皮功能角度探讨运动改善微循环功能的可能机制。方法:将湖北民族大学60名体育专业男性大学生按照随机数表法分为对照组、高强度抗阻运动组和低负荷血流限制运动组,每组20人。低负荷血流限制运动组进行6周(每周3次、每次90 min、运动强度为30%1RM)的低负荷血流限制运动;高强度抗阻运动组进行6周(每周3次、每次90 min、运动强度为70%1RM强度)的抗阻训练;对照组该时间段不进行任何形式的运动训练。分别在干预开始的前1 d以及6周干预结束后次日的晨起空腹状态下对3组受试者微血管血流灌注量、经皮氧分压、肌氧饱和度、一氧化氮、内皮型一氧化氮合酶、内皮素1、血管内皮细胞生长因子及大腿围、肌力等指标进行测试。结果与结论:①运动干预后,低负荷血流限制运动组和高强度抗阻运动组的微血管血流灌注量加热值、血细胞移动速度加热值与对照组及运动干预前相比有显著差异(P<0.05);低负荷血流限制运动组微血管血流灌注量加热值、血细胞移动速度加热值与高强度抗阻运动组相比有显著差异(P<0.05);经皮氧分压和肌氧饱和度与干预前相比有显著性差异(P<0.05)。②运动干预后,低负荷血流限制运动组和高强度抗阻运动组一氧化氮、内皮型一氧化氮合酶、内皮素1、血管内皮细胞生长因子与对照组及运动干预前相比有显著差异(P<0.05)。③运动干预后,低负荷血流限制运动组和高强度抗阻运动组大腿围和大腿肌肉力量与运动干预前相比有显著差异(P<0.05)。④上述结果证实,6周低负荷血流限制运动和高强度抗阻运动可能通过调节内皮型一氧化氮合酶、内皮素1、血管内皮细胞生长因子等血管因子的分泌,提高体育专业大学生大腿微循环功能,并增加大腿肌肉的收缩力量,且低负荷血流限制运动对微血管血流灌注量、血细胞移动速度的干预效果更佳,因此低负荷血流限制运动较高强度抗阻运动在提高微循环功能方面更具优势。
