A mathematical model is suggested for describing the growth 
of a crystal tube with a small inner diameter from the melt by the 
modified Stepanov method with the tube being affected by temperature 
pulses. The behavior of the inner and outer radii of the tube as a 
function of the amplitude and duration of temperature jumps is studied.
