考虑一类半导体方程组的混合初边值问题。在边值函数非负的条件下。

In this paper, we consider the mixed boundary value problem for the semiconductor equations.

在部分显示信息的均衡中，任何情况下消费和财富值都满足非负的条件。

In the partially-revealing equilibrium, nonnegativity of consumption and wealth are satisfied at all times.

如果如果我们把1添加到回报中，你能得到一个非负的数字从而可以使用几何回报。

If we add one to the return, then you've got a number that's never negative and we can then use geometric returns.

And this looks a lot like the average valence electron energy where the lowest values of electronegativity are in the metallic zone and the highest values of electronegativity are on the nonmetallic zone.

这看起来像是平均电子能,最低的电负性在,金属区最高的电负性在,非电子区。

And to measure the intensity of unequal sharing, we take the difference in electronegativity, which I am going to use the Greek symbol chi for.

要度量非平均的程度，我们考虑电负性的差异，我要用希腊语第22个字母chi来表示电负性。
