A certain class of ceramic and metallic materials can be manufactured by the self-propagating high-temperature synthesis method. Even though by now this process has included reaction systems of the solid-gas and solid-liquid types, the original work was directed towards the reactions investigated where not only the reactants but also the final products formed in the solid phase. These reactions are therefore generally referred to as gasless, solid-solid or condensed phase combustion reactions.  3, record 10, English, - condensed%2Dphase%20combustion

Record number: 10, Textual support number: 2 CONT

Condensed phase combustion is a complex phenomenon of theoretical and practical interest, in particular, as a method to synthesize materials. This combustion synthesis process involves a self-sustained combustion wave which propagates through initial reactants converting them into a desired product. In condensed phase combustion the initial reactants as well as final, and possibly intermediate products, remain in the condensed phase throughout the reaction. Though the combustion process occurs in a heterogeneous medium composed of reactive particles, typical models of condensed phase combustion treat the medium as homogeneous.  4, record 10, English, - condensed%2Dphase%20combustion

Record number: 11, Textual support number: 1 OBS

It is based on the principle that if two electrodes are inserted in the ground, and if an external voltage is applied across them, there will be a flow of current through the earth from one electrode to the other. If the medium through which the current flows is homogeneous in its electrical properties, the flow lines will be regular and, in a horizontal plane, symmetrical about the line joining the electrodes. Any inhomogeneities in these properties will cause distortions in the lines of current flow. Such distortions indicate the existence of buried material with higher conductivity than its surroundings, so that it attracts the flow lines toward itself, or with lower conductivity so that it tends to force the lines into the surrounding medium.  1, record 11, English, - equipotential%20line%20method
