有人为分布式拒绝服务攻击辩护，说它是类似于表达不满情绪，是合法的。

Some argue that DDOS attacks are, similarly, a legitimate expression of dissent.

运用全概率法，推导出强度为正态分布，应力为其它分布式可靠度全概率求解表达式。

The reliability solution expressions of strength with normal distribution and stress with different ones are given in the paper by total probability methods.

最后给出了该方案的应用实例，用于表达分布式网络环境中基于直接信任和推荐信任的计算模型。

At last, an example is described about trust inferring and policy between direct trust and recommend trust.

因此，如何将这些分布式异构地理模型进行统一表达、管理并集成到虚拟地理环境系统中，是当前亟待解决的难点问题。

So how to define and manage these distributed heterogeneous models uniformly, and how to integrate into the virtual geographical environment system, still remain the problems to be solved urgently.
