BCBST has found it effective to organize its people to address overall enterprise architecture organization in ways that reflect the teams working on its data governance (see Figure 1).
BCBST发现以一种反映团队数据治理工作的方法(见图1)组织其员工处理整个企业架构组织很有效。
As shown in Figure 1, the elements of an effective solution include.

And how we figure that out and how we move in a direction that's both effective and affordable is the work that has to be done over the next two years."

You just need to remember what's happening to z effective, which really tells us what's happening with all the trends, and once you know z effective, you can figure out, for example, what direction the atomic radius should be going into.
你只需要记住有效核电量的规律,实际上它会告诉我们所有的规律,只要你知道了有效核电量的规律,你就可以判断,比如,原子半径会向着哪个方向发展。
So it looks like not too many more than half of you got this correct, so make sure you can look at your periodic table and figure out how to think about ionization energy in terms of z effective, not just in terms of memorizing what that trend is.
看起来只有一半多一点的人,做对了,所以请大家务必做到能够通过观察周期表,并在考虑电离能时,从有效核电量的观点出发,而不是仅仅依靠记住这个规律。
