Poltavets, Ya. Ya. Tomsons, and R. G. Sharafutdinov INTRODUCTION Several methods are at present available for measuring the velocity distribution function of molecules in gas flows. These are the mechanical selection method [1], measurements using the Doppler contour of spec- tral lines excited by a beam of electrons [2], and measurements based on the time taken for the molecules to travel an assigned distance [3]. When using any of these methods the problem arises of interpreting the ex- perimental data, which involves finding a relationship between the results of the measurements and the in- vestigated velocity distribution of the molecules and is common for all the methods used, since in all versions the recorded signal is an integral of the convolution of the distribution investigated with a certain apparatus function. In this paper, using the example of time-of-flight measurements in a molecular beam, we consider two methods of determining gasdynamic parameters related to the moments of the distribution function: the method in which the distribution function is first established using statistical regularization and
