TO THE QUESTION OF THE POSSIBILITY OF DEVELOPING TOOLS AND METHODS FOR INSTRUMENTAL DIAGNOSTICS OF HEAT EXCHANGERS OF TRANSPORT EQUIPMENT IN OPERATION

Heat exchangers are used to stabilize and maintain the temperature regime of various units and systems of cars.The technical condition of heat exchangers in operation is different and unstable.At a certain operating time interval, the technical condition of any of the heat exchangers can become limiting due to the influence of various kinds of oper

Principle analysis of the four key factors of locomotive running speed, working gap, DOPA Mucuna gear modulus and load resistance influencing on magnetoelectric speed sensor output performance was put forward.The effect related to the four key Ceramic Ornament factors were studied and verified by means of its test study, which provided theoretical

This research aims to examining: 1) The learning outcomes differences on theunderstanding and application of physics concept between groups of students who learned through STAD cooperative learning and expository learning; 2) The learning outcome differences on physics concept understanding and application among students with different cognitive st
