本文从理论上阐明用不变量导出的相对稳定度函数或其比值作为点在基准中的份量是符合对基准选择之要求的。

This paper expounds in theory that, we may use the relative stability or their ratio caused by UNVARIABLE as the proportion of the point on datum, which accords with the demands for choice of datum.

稳定元素比值和相容、不相容元素同等富集则表明它们是碳酸岩和硅酸盐混合的原始母岩浆液态不混熔的产物。

The stable element ratio of compatible and incompatible elements implies that they are liquid immiscible congeners coming from a primitive magma consisting of mixed carbonatites and silicates.

无论是从较长的时间尺度还是从较大的空间范围来看，平均波速比值都是非常稳定的。

The average velocity ratios are very steady, whatever in the long time scale or large spatial scale.
