英文摘要	The average conformation properties, such as the a priori probability P-xi eta and the se mental orientation function of polymethylene chains with chain length from N = 13 to N = 21 are investigated by enumeration calculation method based on the rotational-isomeric state (RIS) model. Here non-local interactions of L-J potential are also considered. In the process of tensile deformation, the a priori probability P-t, increases with elongation ratio A, meanwhile the a priori probability Pg+. (or Pg-) decreases with elongation ratio A, and it leads the average energy per bond to decrease. The segmental orientation distribution function of short deformed polymethylene chains may be expressed in the form of
