Aristotle claims that a sensible substance is composed of form and matter, while he insists that it is a unity in a strict sense. So there is the question--in what sense can a composite thing be a unity？ Aristotle＇s key solution lies in his account of matter as potentiality and form as actuality. Many scholars are bewildered by his laconic solutions, and there are mainly two approaches undertaken in interpretations. One is called ＂projective＂; the other is called ＂explanatory.＂ But neither interpretation is satisfying. The main tasks of this paper are to reexamine the problem and the two interpretations, then to argue that the composition of a sensible substance should be understood in light of its coming-to-be; that its unity refers to its being a functional unity.

It is controversial whether δVVαμLζ in Metaphysics Book θ has two distinct senses, one of which is strict, called ＂power,＂ and the other is the ＂more useful sense,＂ called ＂potentiality.＂ This paper argues that there are indeed two senses of δVVαμLζ in Metaphysics θ, refuting Michael Frede＇s ＂unitarian interpretation.＂ Distinguished from power, potentiality is neither Aristotelian nature, nor possibility, nor capacity for being, but rather a way of being. This paper examines the ontological meanings and the features of potentiality as a way of being. Basically, potentiality has a dual status, that is, it is being, on the one hand, and not-being on the other. Furthermore, it has a teleological direction toward its correlative actuality, which explains how potentiality ontologically depends on actuality and why actuality is substantially prior to potentiality.

鄂尔多斯盆地神木气田与周边气田开发效果差异较大,表现出低品质气藏特征,给气田勘探部署及持续稳产带来一定困扰。为了揭示低品质气藏成因,基于不同尺度微观实验手段,对神木气田太原组储层开展了微观特征及形成机理研究。结果表明,神木气田太原组储层具有“富石英、贫长石、岩屑含量较高”的特征,发育小孔—细喉型孔喉组合,孔喉连通性较差,储渗能力较弱,为低孔—超低渗致密砂岩储层;太原组低品质储层的形成受杂基、喷发岩岩屑含量及成岩作用的共同影响。储层在形成过程中,受晚石炭世—早二叠世鄂尔多斯盆地北部内蒙古古隆起火山活动的影响明显,砂岩内喷发岩岩屑和杂基含量普遍较高,喷发岩岩屑为次生孔隙的发育提供了主要物质基础,杂基在堵塞孔隙的同时也产生了一定数量杂基溶孔,对储层的影响具有双重性。成岩过程中的溶蚀作用对于太原组储层的形成至关重要,增孔效应占现今孔隙度的64.3%。晚白垩世末期,燕山运动末幕导致鄂尔多斯盆地构造反转,气水重新调整,盆地东部天然气沿断裂部分逸散,最终形成了现今神木气田太原组的低品质气藏。神木气田下一步勘探重点应在摸清成岩作用宏观展布规律及有利岩性圈闭的基础上,寻找高含量喷发岩岩屑和低含量杂基的发育区。

Geometry and topology are fundamental concepts, which underlie a wide range of fascinating physical phenomena such as topological states of matter and topological defects. In quantum mechanics, the geometry of quantum states is fully captured by the quantum geometric tensor. Using a qubit formed by an NV center in diamond, we perform the first experimental measurement of the complete quantum geometric tensor. Our approach builds on a strong connection between coherent Rabi oscillations upon parametric modulations and the quantum geometry of the underlying states. We then apply our method to a system of two interacting qubits, by exploiting the coupling between the NV center spin and a neighboring13C nuclear spin. Our results establish coherent dynamical responses as a versatile probe for quantum geometry,and they pave the way for the detection of novel topological phenomena in solid state.

亚里士多德论灵魂的多部分与统一性

亚里士多德批评柏拉图对灵魂部分的划分,他认为灵魂的各部分在空间上不可分,仅在定义上可分。"灵魂在定义上可分"指的是各个部分的定义不包含彼此,因此,灵魂仅有三个真正的部分:营养、感知和理性。然而,灵魂的多部分如何构成统一体对于亚里士多德是一个迫切的问题,因为任何一个生物体的灵魂都是单一的形式。《论灵魂》第二卷第三章解释说灵魂的统一性是由于"低级部分潜在地存在于高级部分之中"。本文指出这个解释是不清晰的,灵魂的统一性辩护另有两种可能:一种是在亚里士多德之后的传统中发展起来的"虚拟潜在性"概念,另一种是亚里士多德将生命活动作为整体目的的论证。

论亚里士多德的主动理性与神圣实体

亚里士多德在《论灵魂》第三卷第5章中提出了“主动理性”的概念。关于“主动理性是什么”以及“主动理性与人的理性是何种关系”的争论从古代的漫步学派延续至当代,从未停歇。以托马斯·阿奎那为代表的解释认为主动理性是人的理性灵魂的内在部分,以阿芙罗蒂西亚的亚历山大为代表的解释认为主动理性是与人的灵魂和身体相分离的神圣实体,而当代的物理主义者认为主动理性仅仅是亚里士多德解释理性活动的理论预设。本文支持一种经过更新的“主动理性是神圣实体”的解释。它表明,《形而上学》十二卷第6—9章补充了《论灵魂》第三卷第5章的内容;主动理性不是形式和知识的全体,也不是理性活动的普遍动力原则,而是在作为宇宙的“原初动力因”和“最终目的因”的意义上“制造”了可思对象和人的理性活动。
