核物态方程在理解中子星、黑洞等致密天体的形成过程中起着重要作用。Eos的真实性质在任何密度范围内都是一个争论的问题，不仅在核物理学中，而且在天文学和天体物理学中也是如此。通过对文献资料的整理，建立了EOSS数据库。我们的数据库包含对称核物质和纯中子物质的核状态方程的基本性质。它还包括关于理论模型的详细信息，例如在各个模型中采用的方法和假设。该数据库的新奇之处在于考虑了新的实验探测器，如对称能量、其相对于重子密度的斜率和不可压缩性，这使用户能够检查他们的模型依赖性。我们通过检验不同核EOS之间的模型相关性来展示EOSDB的性能。结果表明，天体物理学中常用的一些理论EOSS并不能令人满意地符合实验约束条件。
The nuclear equation of state (EoS) plays an important role in understanding the formation of compact objects such as neutron stars and black holes. The true nature of the EoS has been a matter of debate at any density range not only in nuclear physics but also in astronomy and astrophysics. We have constructed a database of EoSs by compiling data from the literature. Our database contains the basic properties of the nuclear EoS of symmetric nuclear matter and of pure neutron matter. It also includes detailed information about the theoretical models, for example the adopted methods and assumptions in individual models. The novelty of the database is to consider new experimental probes such as symmetry energy, its slope with respect to the baryon density, and incompressibility, which enables users to check their model dependence. We demonstrate the performance of the EOSDB through examinations of model dependence among different nuclear EoSs. It is revealed that some theoretical EoSs, commonly used in astrophysics, do not satisfactorily agree with the experimental constraints.
