“…In the crust of a neutron star the density increases from the outer layer with 10 6 g/cm 3 to the inner edge where the density is approximately 10 14 g/cm 3 . While the ground state of the matter is a lattice which has anisotropic elastic properties it is customary to approximate it by a homogeneous and isotropic elastic material.…”

“…The first attempts to merge elasticity with special relativity go back to the early 20th century and there have been several other formulations including Synge [2] and Rayner [3]. The most influential work, however, has been the paper by Carter and Quintana [4] who formulated the geometric setting for the theory and derived the basic field equations.…”

In this paper is discussed a class of static spherically symmetric solutions of the general relativistic elasticity equations. The main point of discussion is the comparison of two matter models given in terms of their stored energy functionals, i.e., the rule which gives the amount of energy stored in the system when it is deformed. Both functionals mimic (and for small deformations approximate) the classical Kirchhoff-St. Venant materials but differ in the strain variable used. We discuss the behavior of the systems for large deformations.

“…(72) (73) In like manner it may be shown that if balances of the bridge are made with branch points band c alternately connected to the guard (74) Heferring to eq 73 or eq 74, it will be seen that by making two balances of the bridge instead of the usual one, the effect of slight defects in the insulation of battery and galvanometer leads is taken into account. For eq 73 or 74 to give results accurate to 1 part in 1 million, a.…”

Reference is made to some of the more important contributions that have been made to the s ubj ect of precise measurements of electrical resistance. The sensitivity of bridges when used with the modern high-sensitivity moving-coil galvanometer is discussed rather fully . Special consideration is given to t he methods and apparatus used and to the procedures followed in the National Bureau of Standards in those comparisons in which the precision desired is of the order of 1 part in a m illion.The more important factors limiting the precision of the comparisons, such as load coefficients, terminals, and contacts, thermoelectromotive forces, insulation, and the optical system of the galvanometer, a re disc ussed rather fully. A method of analysis of networks containing both li near and nonlinear four-terminal conductors is given, and the theoretical basis for the experimental procedure used in detert:"\ining the effect of slight defects in the insulation is pointed out. This is followed by a bri ef d:scussion of Ohm's law from the s tandpoint of precise resistance measurements and by a brief disc ussion of units of resistance. Finally, reference is made to more than 100 publications having a more or less direct bearing on the subj ect of resistance comparisons. CONTE NTSPa&,e
