但这些领域的问题不是缺“阿尔法”，而是缺贝塔或者说市场回报。

But the trouble with such areas may not be the absence of alpha but the level of "beta", or market return.

此外，程序员们也提出了很多算法和技巧来减少节点数目，比如阿尔法 贝塔剪枝算法（Alpha-Beta pruning），Negascout搜索算法以及MTD（全称是：Memory enhanced Test Driver，即记忆增强测试驱动，译者注）方法。

In addition, programmers have come up with all sorts of algorithms and tricks such as Alpha-Beta pruning, Negascout, and MTD(f) in order to lessen the number of nodes the computer must examine.

On the other hand, when it came to penetrating solids, penetrating solids, the alpha radiation was poor at penetrating solids, whereas the beta radiation was very good at penetrating solids.

另一方面，当研究穿过固体的时候，嗯，穿过固体，会发现阿尔法射线很难穿过固体，然而贝塔射线,很容易穿过固体。
