The variation of the magnetostatic parameters of type lKhl8N9T austenitic steel under elastic and plastic deformations is investigated. It is shown that not only the amount of deformation but also the manner in which the deformation is carried out has an important effect on the process of austenite decomposition in this steel.

The temperature dependence of the magnetization, the coercive force, and the galvanomagnetic effect of gadolinium-yttrium alloys containing 10, 25 and 35at% yttrium was measured. These curves have an anomalous shape similar to that observed on the corresponding curves for pure gadolinium at temperatures of 210-250°К [3]. They are also similar to the anomalies on the magnetization curves obtained for gadolinium-yttrium alloys with large yttrium contents (greater than 40 at.%) described in [1,2]. We establish that annealing of the alloys changes these anomalies and even makes them disappear. It is suggested that the nature of the anomalous magnetic properties in gadolinium-yttrium alloys and in pure gadolinium are the same and that this is due to breakdown of the noncollinear configurations of the magnetic moments.

The theory of low cloud-layer formation is considered in both the stationary and nonstationary cases. Experimental data obtained by aircraft observations have enabled us to detail the picture of the physical processes—the radiative cooling of clouds, the lagging of the condensation process behind an adiabatic process, and the evaporation from the ground and from the upper cloud-layer surface—affecting the development of low cloud layers.

The general kind of resonance in a system containing a linear rotational coordinate and an N-dimensional quasistatical vector is investigated. The methodology developed in this paper is illustrated on some actual mechanical methods.

The root locus method is proposed for analyzing nonlinear automatic systems permitting harmonic linearization. Procedures for using this method are developed. A third-order nonlinear system is considered as an example.

It is shown that using a system of uncoupled input resonators the band of low-noise operation of a quadrupole amplifier can be made commensurable with its amplification band.
