Paving-and roofing-grade asphalts were obtained at LUKOIL-Permnefteorgsintez Ltd. by mixing peroxidized asphalt and a number
of high-boiling unoxidized petroleum products in certain ratios. The asphalts obtained have improved performance characteristics:
high plasticity and low brittleness temperature.

A focusing magnetic resonance system (MRS) with a new type of supersonic atomic - and molecular - beam source is suggested. The beam sources used in the MRS are discussed and the main operation principles of the suggested supersonic beam source as well as the advantages of this type of source over the rest are shown. An optimization procedure for the magnetic resonance system with the effect of the finite source size taken into account is considered. Numerical results are given and analyzed. The MRS with the new type of beam source possesses higher transmission with low background and is simpler and cheeper in construction as compared to the conventional systems. 相似文献

Necessary and sufficient condition for the stabilizability of linear discrete systems by a static output feedback control are formulated and used in designing algorithms for robust stabilizing controls and controls that ensure concurrent stabilization of a family of discrete systems. Algorithms are implemented by MATLAB and SCILAB with LMISOLVER and SeDuMi interfaces. The results are generalized to random-structure systems. 相似文献

The oscillation dynamics of a nonhysteretic, one-contact superconducting quantum interferometer under low-frequency modulation of an external magnetic flux has been studied. It is shown that even in the case of adiabatic, equilibrium, and nonhysteretic operation modes of a superconducting ring enclosed by a weak link, there can appear chaotic oscillations. The conditions of chaos arising have been considered analytically and numerically; mechanisms and destruction scenarios of periodic oscillations have been studied. The stochastic instability could impose limitations on the increase in sensitivity of nonhysteretic SQUIDs, which was earlier predicted to be high enough. 相似文献

Problems that have arisen during tune-up of the production line for the thermal processing of solid household waste by the
method of burning in a vortical fluidized bed (principally, a new technology for Russia), and means of their solution are
presented. Investigative studies are cited.

Significant distinctions have been observed in the current kinetics and current-voltage characteristics of ZnS: Mn electroluminescent
thin-film emitters measured with pulsed photoexcitation in different (blue, red, and infrared) spectral intervals. The results
show evidence that a recharge of deep centers related to the zinc and sulfur vacancies takes place in the course of the emitter
operation, leading to the formation of space charges in the near-anode and near-cathode regions of the phosphor layer. 相似文献

Using the results of activities on developing and adjusting the processes pertinent to thermal reprocessing of solid domestic wastes (SDWs), that were carried out by VTI specialists along with GUP Ekotekhprom specialists in 1999–2005, we selected operating conditions under which the power installations run in compliance with the requirements (adopted both in Russia and in the EU countries) imposed on the incineration of SDWs and purification of flue gases. It is indicated that ways are currently being considered of increasing the parameters of steam generated at SDW-fired power stations from the existing p = 1.2?1.4 MPa and t sup = 300?320°C to p = 4.0 MPa and t sup = 400°C to make the generation of electricity at them more efficient. Experience gained in this field by the boiler manufacturing plants in Russia is analyzed. 相似文献

The potential of multimedia interactive simulators is discussed. As an example, the simulator for a system measuring vibration parameters is considered. By means of this simulator, the components and operating principle of the measuring system may be studied in dialog mode, as is demonstrated. The application of this system not only as a measuring instrument but also for the reduction of vibration in rotating mechanisms (rotor balancing) is demonstrated. 相似文献
