响应时间分解为您所测试的系统显示了诸如每一项元素的周期等细节。
Response time breakdown shows details such as the duration of each element for the system that you are testing.
当然,它在被人发现或制造前,就是一种元素周期表使得我们期待其存在的元素。
Of course, it was an element the periodic table let us to expect existed before anyone had found it or made it.
事实上,后来的研究已经证明,在元素周期表中,元素不应该严格按照原子质量来排序。
In fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass.
5% And, it turns out that about 75% of the periodic table falls into this category.
而且,它表明元素周期表的,都属于这个种类。
You are allowed to use on the test the official version of the Periodic Table of the Elements which most of you should have by now.
在测试中你们可以使用,化学元素周期表的官方版本,你们应该大部分都有了吧。
So, that's actually the electron configuration we have when we're talking about copper and some other exceptions in the periodic table that you're going to be looking at.
因此,这才是铜原子真正的电子排布,而且我们在元素周期表中,会看到与铜原子类似的,其他例外的情况。
