Are determined Тeff for 223 stars - giants of a disk; acceleration of a gravity on a surface of a star lg g is determined by three methods; abundances of Li, With, N, O, Mg, Na, Si, Ca, Ni, Y, Ba, La, Ce, Pr, Nd and Eu for 177 clamp-giants of the Galaxy disk are received; the evolutionary status of various stars of giants is determined; the model of chemical evolution of the Galaxy disk is constructed. For 55 stars MS belonging to thin and thick disks of the Galaxy, abundances of Na, Al, Ca and as Y, Zr, La, Ce, Nd, and Sm in LTE , and maintenances Ba and Eu are determined in view of superthin structure by a method of a synthetic spectrum is received. Abundances of elements in atmospheresof stars with anomalies in spectra are received, conclusions about the status of stars are made.
