现行<体育法>关于体育法律关系主体的规定存在明显缺陷,即营利性体育组织的法律关系主体地位并未在该法中确立.这种缺陷源于<体育法>立法时社会关系发展并未成熟及社会认识水平有限.而在<体育法>颁行之后,国家体育行政机关等对营利性体育组织有一定认识并逐步探索规制方式.<体育法>修改时应补充和完善体育法律关系主体即营利性体育组织制度. 相似文献

AuthorBase, a working prototype database of authoring system software, was developed as part of a study of authoring software
conducted by the National Library of Medicine. In this article, the authors discuss development issues ranging from the scope
of the database to what information to document. The prototype demonstrates that records of reasonable integrity can be derived
from vendor-supplied information. However, users should understand that the database is only a starting point in searching
for authoring software and a resource for becoming generally familiar with the technology. 相似文献

This paper reports a new method for designing distributed reduced-order functional observers of a class of interconnected systems with time delays. The systems under consideration belong to a class of large-scale systems where each system is formed by a number of interconnected subsystems. Moreover, the interconnections and the states of the local subsystems are subject to heterogeneous time delays. The novel contribution of this paper lies in the development of new coordinate state transformations, which are used to transform the interconnected subsystems into decoupled subsystems. Most significantly, each decoupled subsystem does not contain any time delay in the state vector. Moreover, each decoupled subsystem is expressed in an observable canonical form, with time delays only appearing in the inputs and outputs of the system. Due to this novel structure, a reduced-order functional observer for each decoupled subsystem can be easily designed to estimate the unmeasurable local state vector. The designed observers for the local subsystems do not need to exchange the state estimates amongst themselves, and therefore, each observer for each local subsystem can be designed independently. Because of the state transformations, the designed observers have a more general structure than any of the existing distributed functional observers available in the literature. Numerical examples are given to illustrate the effectiveness and advantages of our results. 相似文献
