Conclusions Satkinsk dolomitic magnesite fired in a rotary kiln using a cycle employed for Styl'sk dolomite can be used to obtain sintered powder with an apparent density 3.15 g/cm3.Compared with the currently produced tarred dolomite-magnesite refractories, the tar-bonded converter refractories made on the basis of powder produced from dolomitic magnesite are characterized by higher densities, strength, and resistance to hydration.Thus, Satkinsk dolomitic magnesite which is hardly used at the present time is a promising raw material for producing converter refractories.Translated from Ogneupory, No. 8, pp. 15–20, August, 1971. 相似文献

The aim of the present work was to study corrosion and electrochemical behavior of Ti-22Nb-6Ta and Ti-22Nb-6Zr (at.%) superelastic alloys under conditions which imitate the performance mode of target devices (bone implants), i.e., under cyclic load in simulated physiological solutions. Open circuit potential (OCP) measurements were carried out on wire specimens in Hank’s solution and artificial saliva at 37 °C with various strain values up to 1.5%. It is shown that at clinically relevant strain values (about 0.2%) the alloys exhibit OCP growth indicating their high stability and resistance to corrosion fatigue under these cycling conditions. At much higher strains (about 1%), fatigue crack initiation and propagation take place, however, the corresponding OCP variation indicates that the fracture process is significantly restrained by reversible martensitic transformation during cycling. 相似文献

A power supply for a copper bromide vapor laser with stepwise charging of the operating capacitance is presented. A technical solution intended for charging the operating capacitance to energies of about 1 J under automatic control of laser operation is described. The effect of the electric circuit parameters on the charging process of the operating capacitance is shown. The operating characteristics of the device are presented. 相似文献

A test scheme is proposed that provides unified measurements in ophthalmological refractometry. The wavelength dependence
has been determined for the optical strength (ametropia) of the optical measure for the radiations in the infrared and visible
ranges for the nominal values defined by ISO standards.

The efficiency of naphthalene degradation by Pseudomonas putida G7 in soil was assessed using a mathematical model. The number of microorganisms and the concentration of naphthalene in soil samples were monitored. The feasibility of a spectrofluorometric method for naphthalene assay in soil samples was compared with high pressure liquid chromatography. A proposed mathematical model described the growth of the naphthalene‐degrading strains and the consumption of substrates (naphthalene, naphthalene degradation intermediates and soil organic substances) in soil. To describe the growth kinetics of microorganisms having high affinity to substrates with low solubility, two differential equations with substrate exponent 2/3 were proposed. These equations were used to describe utilization of soil organic matter. The model parameters characterize the growth rates for different substrates and respective yield coefficients, specific bacterial death and adaptation rates, and also the rates of PAHs degradation and evaporation. These characteristics can be used in choosing the bacterial strains for biopreparations and efficient clean‐up biotechnology of polluted soils. Copyright © 2004 Society of Chemical Industry 相似文献
