本文结合了由微分年龄法测得的哈勃参数H(z)和由HII星系数据推断出来的距离数据D(z)，提出了一种与宇宙学模型无关的方法来约束宇宙曲率。我们采用高斯过程来平滑距离函数，并将其与30个H(z)的值相匹配。每一数对都可以单独地求得一个曲率参数Ω_k。本文得到的完整样本加权平均值为Ω_k=-0.0013±0.0004，显示了Ω_k偏向于取负值。然而，考虑到可能与局部不均匀性相关的系统效应，曲率测量的准确性随着红移的增加而得到提高。因此我们也分析了一个高红移z> 1.5子样本，并认为此子样本更有可能反映出在平滑的大尺度上的宇宙曲率值。该组数据的加权平均值为Ω_k=-0.0111±0.0416，在 1个标准差之内与零一致。该结果与从宇宙微波背景辐射观测推得的平坦宇宙一致。我们希望未来人们能得到更精确的高红移HII星系数据，使得这种方法对曲率参数可以进行更严格的约束。

We propose a model-independent way to determine the cosmic curvature using the Hubble parameter H(z) measured with cosmic chronometers and the comoving distance D(z) inferred from HII galaxies. We employ Gaussian processes to smooth the measure of distance and match it to 30 values of H(z). The curvature parameter Ω_k may be obtained individually for each such pair. The weighted average for the complete sample is Ω_k=-0.0013±0.0004, suggesting a bias towards negative values. The accuracy of the curvature measurement improves with increased redshift, however, given possible systematic effects associated with local inhomogeneities. We therefore also analyze a high-redshift (z>1.5) sub-sample on its own, which is more likely to reflect the geometry of the Universe on large, smooth scales. We find for this set of data that Ω_k=-0.0111±0.0416, consistent with zero to better than 1σ. This result is in agreement with the spatially flat universe inferred from the cosmic microwave background observations. We expect this method to yield even tighter constraints on the curvature parameter with future, more accurate observations of HII galaxies at high z.
