We present the first photometric observations and light curve modelling of the discovered systems GSC 01870-00458 and USNO-A2.0-0975 04721840. Our modelling was carried out using a recent Windows interface version of Wilson and Devinney code based on model atmospheres provided by Kurucz. The accepted models revealed absolute and physical parameters that can be used to study the evolutionary states of systems. The parameters show that primary component is more massive and hotter than the secondary component for both systems, and spectral types of the system components were adopted. Locations of both systems on theoretical mass-luminosity and mass-radius curves revealed a good fit for components of both systems except for the secondary component of the system GSC 01870-00458.

我们介绍了发现的系统GSC 01870-00458和USNO-A2.0-0975 04721840的第一个光度学观测结果和光曲线建模。我们的建模是基于由Wilson提供的模型大气使用的Windows界面版本的Wilson和Devinney进行的。库鲁兹 公认的模型揭示了可以用于研究系统进化状态的绝对和物理参数。参数表明，两个系统的主要成分都比次要成分更重，更热，并且采用了系统成分的光谱类型。这两个系统在理论质量光度和质量-半径曲线上的位置都表明，除了系统GSC 01870-00458的次要部件之外，这两个系统的部件都非常适合。
