The Wentzel–Kramers–Brillouin method is employed to study the cut-off frequencies of the horizontal shear waves in a freestanding functionally graded piezoelectric–piezomagnetic material film with the electrically and magnetically open boundary conditions. An analytical solution, which could be used in analyzing the problems of various functionally graded materials, is proven to have high precision by analytical analysis and a numerical example. The results reveal that the set of cut-off frequencies is a series of approximate arithmetic progressions. A theoretical foundation based on the relationship between the cut-off frequencies and the materials’ gradient property is established for nondestructive evaluation.  相似文献

High-resolution electron microscopy is used to determine the translation order domains of gamma particles in arrangements formed during Ostwald ripening in the alloy Ni-12at.%Al. Such arrangements have been often identified with the operation of a mechanism of particle splitting in the late stages of the coarsening process, that is when the elastic strain contribution becomes predominant. It is shown that the translation order domains are not identical in such a particle array. This leads to the conclusion that particle splitting is not necessarily the mechanism responsible for the formation of such characteristic particle arrangements. Instead, particle migration can also be considered to be the responsible mechanism for the formation of such a correlated gamma-particle spatial distribution observed in Ni-based alloys.  相似文献

Coupling atom probe tomography and transmission electron microscopy, the temporal evolution of γ′ precipitate morphology and size distribution and compositional width of the γ/γ′ interface, have been tracked in a model Ni-14Al-7Cr (at.%) alloy, during isothermal annealing at 800?°C subsequent to rapid quenching. During the initial annealing period, coalescence-dominated growth and coarsening of γ′ precipitates are accompanied by a gradual decrease in the interface width, eventually leading to classical LSW coarsening with a constant interface width at extended annealing time periods.  相似文献

This paper considers whether Hegel's master/slave dialectic in the Phenomenology of Spirit should be considered as a refutation of solipsism. It focuses on a recent and detailed attempt to argue for this sort of reading that has been proposed by Frederick Beiser – but it argues that this reading is unconvincing, both in the historical motivations given for it in the work of Jacobi and Fichte, and as an interpretation of the text itself. An alternative reading of the dialectic is proposed, where it is argued that the central problem Hegel is concerned with is not solipsism, but the sociality of freedom.  相似文献

In this article I attempt to reconstruct David Hume's use of the label ‘experimental’ to characterise his method in the Treatise. Although its meaning may strike the present-day reader as unusual, such a reconstruction is possible from the background of eighteenth-century practices and concepts of natural inquiry. As I argue, Hume's inquiries into human nature are experimental not primarily because of the way the empirical data he uses are produced, but because of the way those data are theoretically processed. He seems to follow a method of analysis and synthesis quite similar to the one advertised in Newton's Opticks, which profoundly influenced eighteenth-century natural and moral philosophy. This method brings him much closer to the methods of qualitative, chemical investigations than to mechanical approaches to both nature and human nature.  相似文献

According to the Cambridge Platonist Henry More, individual ‘spirits’ – the souls of humans and non-human animals – are extended but cannot be physically divided. His contemporaries and recent commentators have charged that More has never given an explication of the grounds on which the indivisibility of spirits is based. In this article, I suggest that exploring the usage that More makes of the analogy between spirits and light could go some way towards providing such an explication. More compares the relation between spirit and matter to the relation that, according to Aristotelian theories of light, holds between ‘intentional species’ and matter. I will argue that the purpose of his comparison is to highlight that both intentional species and spirits are existentially independent from matter. The existential independence of intentional species from matter expresses itself in the fact that light is not moved through the motion of the illuminated body. The existential independence of spirits from matter expresses itself in the fact that when a body that is coextensive with a spirit is divided, the spirit is not thereby divided but rather contracts into the remaining living organism.  相似文献

In this paper, I investigate Louis de La Forge's argument against body–body causation. His general strategy exploits the impossibility of bodies communicating their movement by transfer of motion. I call this the ‘non-transfer’ argument (NT). NT allows La Forge both to reinterpret continuous creation in an occasionalistic fashion and to support his non-occasionalistic view concerning mind–body union. First, I present how NT emerges in Descartes’ own texts. Second, I show how La Forge recasts it to draw an occasionalistic account of body–body interactions, and I discuss how La Forge supports NT with continuous creation. Third, I conclude by suggesting that this further step of his argument does not undermine his non-occasionalistic account of mind–body union.  相似文献

In Western democratic society, the specificity of the bioethical debate over the life-sciences involves bringing together many different study factors. The dilemmas raised by the new scientific discoveries highlight how contemporary common sense is plagued by a profound feeling of anguish over possible future anthropological developments. One of the central problems is the social construction of consent as a psychological strategy seeking to orient public opinion toward accepting new applications of science and technology. On the one hand, the general features in the epistemological analysis of the mind-brain identity are called into question; and on the other, together with all those research directions concerned with the “meaning of life,” we enter the dimension of the complex issue inherent in the possibility of establishing if there exists something transcending thought and what it may be. In both cases a problem is raised on which the meaning of human life and the world depend, while between the two universes described by medical science and ethical-philosophical thought a window of opportunity for important psychological research is opened. In order to understand such phenomena the present article defends the theory that social psychology must adopt as its subject matter “thinking society,” that is, society characterized by discussion and reasoning on themes relevant to bioethics.  相似文献

Ervin Laszlo's revolutionary concept of the Akashic Field and his connectivity hypothesis offer elegant solutions for the baffling paradoxes associated with “anomalous phenomena”—otherwise unexplainable observations which many scientific disciplines encountered in the course of the 20th century. This article explores the ground-breaking contributions that Laszlo's work has made to psychology by providing a plausible conceptual framework for a large number of observations and experiences amassed by modern consciousness research, which challenge the most fundamental assumptions of the traditional scientific worldview.  相似文献
