But hang on - - how do we know that radioactive atoms don ' t senesce 但是，听清楚了?我们怎么知道放射性原子不衰老？

Then the frame of the complex industry process control system based on multi - agent theory for a broad senesce was designed . the single agent model and the behavior rule for it were defined 进一步介绍广义multi - agent理论的基础上探讨工业过程控制领域通用的基于multi - agent的复杂工业控制系统的架构，定义了符合工业过程控制系统特点的个体agent模型和个体agent的行为规则。

So in fact , if they senesce just a tiny tiny bit over time - - that is , if their half - life gets shorter , very very slowly - - we wouldn ' t actually be able to tell that this was happening in the time that we took our measurements , because the acceleration in the rate of atoms decaying ( relative , of course , to the number that had not decayed already , which is always decreasing ) would be too tiny to be statistically detectable 所以在事实上，如果它们随时间衰老得只那么一点点， ?就是说，如果它们的半衰期缩短得非常慢?那么我们实际上不可能知道，在我们测量期间发生过衰减，因为原子衰减的速率加速得太小，统计学上检测不出（当然，是相对于不曾衰减的数目而言，不曾衰减的原子数目总是在减少） 。
