Uniprocessor designs have built-in bottlenecks.the address and data buses restrict data transfers to a one-at-a-time flow of traffic.the program counter forces instructions to be run in strict sequence.even if improvements in performance are achieved by means of faster processors and more instruction parallelism,operations are still run in strict sequence.however,in a uniprocessor,an increase in processor speed is not the total answer because other factors,such as the system bus and memory,come into play.

单处理器设计有内置的一些瓶颈。地址和数据总线限制数据传输的同时同地址的数据冲突情况。即使是通过更快的处理器和更多的并行指令，当然也包括维护，这些方式来提高的性能，程序的运行仍然被限制在严格的程式规则中。然而，在一个单处理器里，处理器速度的提高时不能完全解决这个问题的，这是因为像系统总线和存储器等其他因素同样在起作用。

In addition, basing on the tight-binding model of the single electron and transfer matrix method, we study the charge transfer properties of Fibonacci sequence and discuss specially the dependent of electronic transmission on energy and the length of the sequence. We find some resonant peaks can survive in relatively longer Fibonacci sequences than random sequences, which also implies there are long-range correlations in Fibonacci sequences.

从Anderson紧束缚模型出发，采用传输矩阵方法研究了Fibonacci序列的电子输运特性，讨论了输运系数对能量及其序列长度的依赖关系，发现随着序列的长度增加，具有好的透射性的电子态数量有所减少，但相对于随机序列而言，共振能态可以在更长的序列中存在，进一步证明了Fibonacci序列中存在有较强的长程关联行为。
