查询词典 atomic element

The atomic weight is the relative weight of an atom of the element.

原子量是该元素中原子的相对重量。

Atoms of the same element that differ in their atomic weight are called isotopes.

具有不同原子量的同一种元素被称为同位素。

In order to comprehensively develop and utilize C. cathayensis exocarp and provide reference for protection of ecological environment at growing districts of C. cathayensis, inorganic constituents in C. cathayensis exocarp were analyzed by atomic absorption spectrometry. The results showed that content of K element in C. cathayensis exocarp was high, and the results of wet digestive and dry digestive methods were same.

为了综合开发利用山核桃外果皮，为山核桃产区生态环境的保护提供参考，经原子吸收分光光度法分析得知：山核桃外果皮的无机成分中含有较高的钾元素，山核桃外果皮可以作为制备工业钾盐的原料，湿消化法和干消化法处理外果皮所得的结果基本一致。
