摘要:

Part II of the paper concerns the erratic time dependence of natural patterns of fluids, particularly those fluids with low Prandtl number. Possible explanations of the phenomena and experimental tests in simple situations are presented. Part I of the paper concerned the concept of pattern instabilities and major pattern defects.

摘要:

Studies of atomic structure are being extended into highly ionised regimes in which relativistic and quantum electrodynamic interactions and effects due to the finite size of the nucleus may dominate the dynamical structure of the ions. These highly ionised atoms have important applications in astrophysics, fusion plasma and X-ray laser technology, and provide new tests of computational atomic theory.

摘要:

As predicted more than 50 years ago, a lowering of dimensionality should lead to a basic change of ordering in physical objects. This paper gives a brief survey of phase transitions in two-dimensional systems and illustrates results obtained for absorbed layers on solid surfaces. Critical behaviour of two-dimensional systems is of import in obtaining optimum operating conditions for technical applications of such systems.

摘要:

We present experimental results to illustrate the percolation model, and use this model to describe the structure and mass distribution of clusters, the increase of the connectivity as the percolation threshold is approached, as well as transport properties of electrical percolating networks. We discuss results obtained from neutron and light scattering and from mechanical measurements. A good agreement between theory and experiment allows the growth of polymer clusters during the gelation process to be understood. Results obtained from mechanical measurements are quite similar to the behaviour of electrical properties of percolating networks, but are not yet understood completely.
