Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Formalized description of indicator signal registered by the device of chemical exploration Vlasov Y.N., Rumyantsev A.B., Vasin A.I., Ermolaev V.J. In work the principles of formation of an indicator signal of the device, for mathematical modeling of process of functioning of the device of chemical investigation and estimation of his (its) efficiency are offered, expressed in the equations. The developed model allows carrying out (spend) researches of the methodical and constructive decisions fixed in a basis of work of the device, and also creation of numerous virtual situations at training the operator.
