人体测量学并不是现代社会的产物。有着很长发展历史的人体比例理论中就包含了现代人体测量学的基本内容,尽管其还不够系统完整,但至少说明了在艺术创作中诞生的人体比例理论对现代人体测量学的影响。并随着时间的推移而不断的完善发展,为现代人体测量学的系统提出奠定了坚实的基础。 相似文献

The paper questions the ability of current university systems to respond appropriately to the complex demands of an Information
Economy. It argues that new relationships between creative subjects and technology require new thinking about the nature and
purpose of universities per se. In particular, attention is drawn to the growing involvement of the private sector in higher
education. It is argued that it may not be appropriate to think of the `university of the future' in terms of current public
sector and quasi public sector institutions, but rather in terms of an emporium, based on an international trade in educational
services, and with the `University' as we now understand it occupying the functions of licensing, quality assurance and cultural
custodianship.

All titanium alloys are highly reactive in the molten condition and so are usually melted in a water-cooled copper crucible to avoid contamination using processes such as Induction Skull Melting (ISM). These provide only limited superheat which, coupled with the surface turbulence inherent in most conventional mould filling processes, results in entrainment defects such as bubbles in the castings. To overcome these problems, a novel tilt-casting process has been developed in which the mould is attached directly to the ISM crucible holding the melt and the two are then rotated together to achieve a tranquil transfer of the metal into the mould. From the modelling point of view, this process involves complex three-phase flow, heat transfer and solidification. In this paper, the development of a numerical model of the tilt-casting process is presented featuring several novel algorithm developments introduced into a general CFD package (PHYSICA) to model the complex dynamic interaction of the liquid metal and melting atmosphere. These developments relate to the front tracking and heat transfer representations and to a casting-specific adaptation of the turbulence model to account for an advancing solid front. Calculations have been performed for a 0.4 m long turbine blade cast in a titanium aluminide alloy using different mould designs. It is shown that the feeder/basin configuration has a crucial influence on the casting quality. The computational results are validated against actual castings and are used to support an experimental programme. Although fluid flow and heat transfer are inseparable in a casting, the emphasis in this paper will be on the fluid dynamics of mould filling and its influence on cast quality rather than heat transfer and solidification which has been reported elsewhere. 相似文献
