摘要：
Approximate analytic expressions for determining the transmission of neutron benders which take into account reflectivity losses using the mean number of reflections agree well with computer simulation results which track the neutron trajectories directly, provided that the reflectivity is high. The exact calculation which can be performed using exponential integral functions for any value of the reflectivity is presented. Ray-tracing techniques for determining the transmission and number of reflections for non-perfect reflectivity can therefore be replaced by direct calculation.
