Over here in the lower left corner, we have elements that as a group have very low values of average valence electron energy.
在底层的左侧角落,我们看到以组为单位的,价电子能较低的元素。
And in contrast, in the lower left hand part of the periodic table, these 2 quantities are low, so also what we're going to see is low electronegativity.
相反地,在周期表的左下部分,这两个量的值都很小,因此我们会看到这里的电负性也很低。
So, we're going to begin down in the lower left corner.
我们将从左下方开始。
And then they found that they could freeze-dry this preparation of virus, and freeze-drying to lower the temperature, freeze it, then extract out all the water, so you're left with a powder, basically a powdered form of the virus, that could be shipped all over the world, and then reconstituted by adding water to it.
研究者们发现可以冷冻干燥这些病毒制剂,冷冻干燥就是就是降低温度,冷冻病毒,然后提取出所有水份,然后就剩下一些粉末,这主要是粉末状的病毒,这样就能将它运往全世界,并可以通过加水来恢复病毒的活性
The proton number is in the lower left corner.
