Nearby detached double-lined eclipsing binaries with most accurate data were studied and 290 systems were found with at least one main-sequence component having a metallicity $0.008\leq Z\leq 0.040$. Stellar parameters, light ratios, Gaia DR2 trigonometric parallaxes, extinctions and/or reddening were investigated and only 206 systems were selected eligible to calculate empirical bolometric corrections. NASA-IPAC Galactic dust maps were main source of extinctions. Unreliable extinctions at low Galactic latitudes $|b|\leq5^o$ were replaced with individual determinations, if they exist in the literature, else associated systems are discarded. Main-sequence stars of remaining systems were used to calculate bolometric corrections ($BC$) and to calibrate $BC-T_{eff}$ relation, which is valid in the range 3100-36000 K. De-reddened $(B-V)_0$ colours, on the other hand, allowed us to calibrate two intrinsic colour effective temperature relations, where the linear one is valid for $T_{eff}>10000$ K, while the quadratic relation is valid for $T_{eff}<10000$ K, that is, both are valid in the same temperature range $BC-T_{eff}$ relation is valid. New $BC$ computed from $T_{eff}$ and other astrophysical parameters are tabulated, as well.

盖亚时代附近主序星的经验辐射热校正系数

研究了附近具有最准确数据的分离双线食双星，发现了 290 个系统，其中至少有一个主序分量的金属丰度为 $0.008\leq Z\leq 0.040$。研究了恒星参数、光比、Gaia DR2 三角视差、消光和/或变红，仅选择了 206 个系统有资格计算经验辐射热校正。NASA-IPAC 银河尘埃图是灭绝的主要来源。在低银河系纬度$|b|\leq5^o$ 的不可靠灭绝被个别确定取代，如果它们存在于文献中，否则相关系统将被丢弃。其余系统的主序星用于计算热校正（$BC$）并校准$BC-T_{eff}$关系，该关系在3100-36000 K范围内有效。去红化$(BV)_0 $ 颜色，另一方面，允许我们校准两个固有的颜色有效温度关系，其中线性关系适用于 $T_{eff}>10000$ K，而二次关系适用于 $T_{eff}<10000$ K，即两者在同一温度范围内有效$BC-T_{eff}$关系有效。从 $T_{eff}$ 和其他天体物理参数计算出的新 $BC$ 也被制成表格。
