We present results of the analysis of photometric and spectroscopic observations of the young stellar complexes in the late giant spiral galaxy UGC 11973. Photometric analysis in the \(UBVRI\) bands have been carried out for the 13 largest complexes. For one of them, metallicity of the surrounding gas \(Z = 0.013 \pm 0.005\), the mass \(M = (4.6 \pm 1.6) \times {{10}^{6}}{\kern 1pt} {{M}_{ \odot }}\), and the age of the stellar complex \(t = (2.0 \pm 1.1) \times {{10}^{6}}\) yr were evaluated, using spectroscopic data. It is shown that all complexes are massive (\(M \geqslant 1.7 \times {{10}^{5}}{\kern 1pt} {{M}_{ \odot }}\)) stellar groups younger than \(3 \times {{10}^{8}}\) yr.

我们介绍了在晚期巨型旋涡星系UGC 11973中年轻恒星配合物的光度学和光谱学观察结果的分析结果。\（UBVRI \）波段的光度分析已针对13个最大的配合物进行。其中之一就是周围气体的金属性（Z = 0.013 \ pm 0.005 \），质量\（M =（4.6 \ pm 1.6）\倍{{10} ^ {6}} {\ kern 1pt} { {M} _ {\ odot}} \），并使用光谱数据评估了恒星复合体的年龄（（t =（2.0 \ pm 1.1）\时间{{10} ^ {6}} \） yr。结果表明，所有复合物都是庞大的（\（M \ geqslant 1.7 \ times {{10} ^ {5}} {\ kern 1pt} {{M} _ {\ odot}} \））比\（ 3年{{10} ^ {8}} \）年。
