• Abundance ratio of isotopes
  同位素的相对丰度
• Note 3 : actinide abundance ratios may be applied to measurements of stellar ages
  注3 :锕充足比率可用于测量恒星的年龄
• Surprisingly for astronomers and nuclear physicists , the abundance ratios of thorium to other heavy elements are very similar to ratios found for milky way stars
  出乎意料的天文学家和核物理学家丰比率钍等重元素非常相似比率发现银河系恒星
• This star is known to have high abundance ratios of elements heavier than iron , and is thought to be severely contaminated by some explosive synthesis of heavy elements ( note 2 )
  这颗恒星是已知有高丰度的比例更重的元素,比铁,有人认为这是受到严重污染,一些炸药合成重元素(注2 )
• The sims showed that the result of the concentration and the abundance ratio of li - 7 and li - 6 in the palladium wire were changed . it implied that the laser triggering on a pd wire with a low gas - loading ratio may have produced the nuclear process
  并通过二次离子质谱仪( sims )测出了钯丝中锂- 7和锂- 6的浓度变化和丰度比变化，说明在低充氢率的钯丝中，在小功率激光的触发下有产生核过程的可能。
• Models of element synthesis during the supernova explosions predict that the abundance ratios of actinides with respect to other stable elements heavier than iron are very sensitive to the environment of the explosion , such as the entropy and the ratios of protons , neutrons and electrons
  模型元素的合成,在超新星爆炸预言的丰度比锕对于其他稳定更重的元素,比铁很敏感,对环境造成的爆炸,如熵和比例的质子,中子和电子
• Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment . the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment . the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins
  2沉积物地球化学与化学风化进程和机械剥蚀率化学风化指数与化学风化率属于表征化学风化作用意义不同的函数，前者为相对概念反映流域岩石在原岩基础上己发生淋溶作用的深度，主要受到了气候因子的深刻影响(中国流域沉积物化学风化指数由北到南呈有规则的递增序列，气候因子对风化进程的影响掩盖了岩性的巨大差异) ，而化学风化率含义是指单位流域面积岩石风化淋溶产生的离子绝对总量。
