The condition of an unsteady temperature discontinuity is derived for a one-dimensional heat flux in a gas at rest.
In this special case of axonometric projection, the projectors are taken from points on the contour of an object to meet the plane of projection obliquely.
In der Skizze Abb. 7 ist gezeigt, wie durch das Herunterdrehen des Heizelementes zwar der Reflexionswinkel seiner Größe nach erhalten bleibt, aber der Brennpunkt wesentlich verschoben wird.

An analytical continuum solution of the Rayleigh problem in slip flow with applied magnetic field is obtained using a modified initial condition and slip boundary conditions. The results are uniformly valid for all times and show that the velocity slip and the local skin friction coefficient remain almost unaffected by the imposition of the magnetic field for small times. They increase however with the magnetic field for large times. The present results reduce to the corresponding results of the hydrodynamic case when there is no magnetic field.

In exploring the nature of a GM discharge a small amount of tritium is mixed with commercial Q-gas (1.3% n-butane and 98.7% helium). After operation the counter is found to be badly contaminated. Attempts to remove the activity fail to yield satisfactory results. An analysis of the gas mixture reveals that tritium activity is present in n-butane, with none being found in the expected decomposition products. An ion-molecule reaction involving n-butane is proposed to explain the results.

The concentration diffusion coefficient, D12, is measured for the equimolar mixtures of Ne-Ar, Ne-Xe, Ne-H2, Xe-H2, H2-N2 and H2-O2 binary gas systems in a two-bulb metal apparatus in the temperature range 0 C to 100 C. These values are compared with the existing data on these systems and with the predictions of the kinetic theory in conjunction with the modified Buckingham exp-six potential. Unlike the thermal diffusion coefficient, with the simple theory it is possible to predict D12 within a few percent even for systems involving polyatomic gases. The smoothed experimental D12 values are also used to obtain data for the coefficients of viscosity and thermal conductivity at round temperatures and compositions for these systems.
