The combustion of ultrahigh molecular weight polyethylene (UHMWPE) in airflow perpendicular to the polyethylene surface (counterflow flame) was studied in detail. The burning rate of pressed samples of UHMWPE was measured. The structure of the UHMWPE–air counterflow flame was first determined by mass spectrometric sampling taking into account heavy products. The composition of the main pyrolysis products was investigated by mass spectrometry, and the composition of heavy hydrocarbons (C7—C25) in products sampled from the flame at a distance of 0.8 mm from the UHMWPE surface was analyzed by gas-liquid chromatography mass-spectrometry. The temperature and concentration profiles of eight species (N2, O2, CO2, CO, H2O, C3H6, C4H6, and C6H6) and a hypothetical species with an average molecular weight of 258.7 g/mol, which simulates more than 50 C7—C25 hydrocarbons were measured. The structure of the diffusion flame of the model mixture of decomposition products of UHMWPE in air counterflow was simulated using the OPPDIF code from the CHEMKIN II software package. The simulation results are in good agreement with experimental data on combustion of UHMWPE. 相似文献

The passage of laser radiation through a scattering medium is studied experimentally. A method of determining the optical
characteristics of a scattering media is proposed. The method is based on the measurements of time distributions of the intensity
of ultrashort laser pulses for two layer thicknesses of the medium to be studied. The measurements are carried out with the
use of a single-photon counting system. The proposed method is used to determine the absorption and scattering coefficients
of a model medium from the experimental data. 相似文献

Change in the stability of overcooled austenite of high-carbon manganese-silicon steel relative to decomposition via the intermediate stage upon isothermal holding and martensitic γ → α transformation upon subsequent cooling has been studied using dilatometry and X-ray diffraction. The kinetics of low-temperature bainite transformation has been studied. The tetragonality of the crystal lattice of bainite α-phase caused by the superequilibrium content of carbon was found. 相似文献

A recently proposed new large class of one-dimensional binary sequences, called extended pseudorandom sequences, is investigated.
It is shown that they enable one, in practice, to optimize a radiation-physical experiment and to solve problems of emission
planar tomography more effectively using integral-code measurement systems. 相似文献

Experiments are conducted on pipe production from continuous-cast billet made of TP 304L and TP 316L corrosion-resistant steel from various suppliers. A wide range of pipe is industrially produced by hot pressing and cold and hot rolling. Assessment of pipe quality shows compliance with the relevant standards. 相似文献
