总结了太阳光球和陨石CI球粒陨石丰度测定的所有元素，并选择了目前最好的光球丰度。一些元素的陨石和太阳丰度（e。例如，在一个实施例中，稀有气体、铍、硼、磷、硫）。光球丰度给出了氢（X = 0.7491）、氦（Y = 0.2377）和重元素（Z = 0.0133）的质量分数，导致Z/X = 0.0177，低于以前汇编中广泛使用的Z/X = 0.0245。考虑氦和重元素沉降的标准太阳模型的最新结果意味着光球丰度和质量分数不等于原太阳丰度（太阳系丰度的代表）。原太阳元素和同位素丰度是通过考虑沉降效应而从光球丰度导出的。原太阳质量分数为X-0 = 0.7110，Y-0 = 0.2741，Z（0）= 0.0149。太阳系和光球丰度表用于计算所有元素的自洽凝结温度。
Solar photospheric and meteoritic CI chondrite abundance determinations for all elements are summarized and the best currently available photospheric abundances are selected. The meteoritic and solar abundances of a few elements ( e. g., noble gases, beryllium, boron, phosphorous, sulfur) are discussed in detail. The photospheric abundances give mass fractions of hydrogen (X = 0.7491), helium (Y = 0.2377), and heavy elements (Z = 0.0133), leading to Z/X = 0.0177, which is lower than the widely used Z/X = 0.0245 from previous compilations. Recent results from standard solar models considering helium and heavy-element settling imply that photospheric abundances and mass fractions are not equal to protosolar abundances ( representative of solar system abundances). Protosolar elemental and isotopic abundances are derived from photospheric abundances by considering settling effects. Derived protosolar mass fractions are X-0 = 0.7110, Y-0 = 0.2741, and Z(0) = 0.0149. The solar system and photospheric abundance tables are used to compute self-consistent sets of condensation temperatures for all elements.
