摘要:

A brief survey is given of the various physical, astronomical and radioastronomical data pertaining to cosmic ray nuclei with energies above 1 Gev. A theory is then outlined, the details of which are due to Ginzburg and Syrovatskii, in which it is suggested that these cosmic rays are produced in supernovae and that their properties—such as chemical composition, energy spectrum and spatial distribution—are determined partly by their acceleration in and ejection from the sources and partly by various physical processes occurring during the passage of the cosmic rays from their sources to the earth.

摘要:

Information from the growth of crystals in a liquid might help to extend our knowledge of the liquid state. Glass is a convenient material for this, since the rates of reaction are generally slow and can be studied over a very wide range of conditions, though the necessarily high temperatures lead to experimental problems.

摘要:

A qualitative account is given of the main processes whereby a paramagnetic spin system attains thermodynamic equilibrium with the lattice in which it is embedded. The basic theory needed for calculating the spin-lattice relaxation times governing the rate of establishment of equilibrium between the two systems is sketched. It is possible to produce microwave phonons of the right frequencies for use in ultrasonic spin-resonance experiments, to observe directly the interaction between the spin system and phonons of a particular frequency and so avoid complications inherent in the conventional spin-lattice relaxation experiments (where a thermal distribution of phonons is involved).
