(可能是用某些实验得出了一个元素的atomic number 结果找不到已知相应的元素 那么有可能就是发现了一种新元素 或者实验错误)讲的繁琐一点就是there have been atomic numbers[←我觉得应该要有s],and there's no known element for such atomic numbers.atomic number和element之间介词用for 在这个which的定语从句...
Synchrotron-based X-ray spectroscopy is a powerful tool to study element-specific magnetism. Here, X-ray detected paramagnetic resonance on molecular quantum bit candidates is demonstrated, paving the way toward the element-specific detection of coherently excited spin superposition states. Andrin Doll ...
解析 首先句子后面是作定语的,由主句可以知道,修饰的是主语element.因为atoms是原子的意思,对于元素来说,逻辑关系自然是“元素里的原子”,所以element和atoms具有从属关系,用whose(注意啦!在定语从句表示从属关系的时候,关系词whose不仅仅适用于人,也可以适用于物)...

Synthesis of a New Element with Atomic Number Z=117 The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes (293)117 and (294)117 were produced in fusion reactions between ... TO Yu,FS Abdullin,PD Bailey,... - 《Physical Review Letters》...
Although the image of atomic coordinates in the first demonstration shows no Z-contrast (where Z is the atomic number of the element), the OCSVM can work for STEM images exhibiting Z-contrast if the dopants are excluded since dopants can complicate the one-class classification. ...
How do I interpret the element boxes? Located right above the Englishname for each element, the largest letters represent itschemical abbreviation. The largest number is the element’satomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation...
For example, the atomic weight of carbon is given as [12.0096, 12.0116]. The table provides a list of chemical elements and their atomic weights. Chemical elements element symbol atomic number atomic weight Elements with an atomic weight given in square brackets have an atomic weight that is...
