In this work we study the properties of a relativistic mixture of two nonreacting dilute species in thermal local equilibrium. Following the conventional ideas in kinetic theory, we use the concept of chaotic velocity. In particular, we address the nature of the density, or pressure gradient term that arises in the solution of the linearized Boltzmann equation in this context. Such an effect, also present for the single component problem, has, so far, not been analyzed from the point of view of the Onsager resciprocity relations. To address this matter, we propose two alternatives for the onsagerian matrix which comply with the corresponding reciprocity relations. The implications of both representations are briefly analyzed.
在这项工作中，我们研究了处于热局域平衡的两种不发生反应的稀薄物种的相对论混合物的性质。遵循动力学理论中的传统观点，我们使用了混沌速度的概念。特别地，我们探讨了在此背景下线性化玻尔兹曼方程解中出现的密度或压力梯度项的性质。这种效应在单组分问题中也存在，到目前为止，尚未从昂萨格互易关系的角度进行分析。为了解决这个问题，我们为昂萨格矩阵提出了两种符合相应互易关系的替代方案。简要分析了这两种表示的含义。
