## Abstract

We have computed the one-point pdf of small-Angle CMB temperature fluctuations due to cosmic (super-)strings with a simple model of the bended long segments numerically and have showed that it reproduced the feature of the numerical simulation in Fraisse et al. [3], especially skewness in one-point probability distribution function. We found that skewness would appear if we take curvature of segment and its correlation with its velocity into account. If a segment has a curvature, the symmetry of temperature fluctuations between positive and negative value is broken and the amplitude of the asymmetry depends on the angle between the curvature vector and the velocity vector of the segment.
