[求助] 一小段文献求翻译 已有3人参与

The measured distance between the two nearest atom rows is 2.22A ̊, i.e., close to the (111) interplanar distance of Pd (2.25 A ̊ ). Rows of Pd atom can be observed on the surfaces of most Co@Pd particles, denoting the uniformity of the Pd shell. The Co@Pd nanoparticles consist of 34 mol% Pd and 66 mol% Co, determined by ICP-AES measure- ments, that is consistent with the expected Pd/Co molar ratio (33/67). On the basis of the particle’s size, composi- tion, and lattice parameters, and assuming that the parti- cles are spherical, the estimated thickness of the Pd shell was 0.54 nm, i.e., about 2.4 atomic layers.

主要是我想知道是怎么知道Pd壳有多厚的,求大神们赐教,谢谢了

苦艾同学,在下的一点愚见:
On the basis of the particle's size , composition , and lattice parameters , and assuming that the particles are spherical ,  the estimated thickness of the Pd shell was 0 ...

谢谢,有点了解了!但是还是不是很清脆

0.54纳米 约相当于2.4倍原子层

这个我看懂了,我不太明白前面是怎么得出来的这个结果???

On the basis of the particle’s size, composi- tion, and lattice parameters,应该是靠这一系列的数据计算的吧,
