这一产品的制造商向我们保证说他们没有牺牲质量。
The makers of the product assured us that there had been no sacrifice of quality.
Mendeleev is the one who taught us that the properties of the elements are a function of the atomic mass.
门捷列夫教授我们元素特性,是元素质量所起的功能。
And in terms of equations that we use, it's sometimes easier to plug in the fact, since momentum is equal to mass times velocity.
在我们使用方程这方面,事实上有时是很容易代入的,因为动量等于质量乘以速度。
We have a table of the elements with properties varying periodically with atomic mass, so we compress all of that information and refer to it as the Periodic Table.
我们有一个元素表,其中的元素的特性,随着原子质量的改变而引起周期性的变化,所以我们将所有的信息精简,将它变成一个周期表。
