The application of additional momentum and adaptive learning rate overcomes the limitation effect of BP rule, accelerates the training speed and strengthens the generalization ability of network.
由于采用附加动量项和自适应率等措施，克服了BP规则的局限性，加快了训练速度，增强了网络的泛化能力。

But the increase of data rate is limited by band-limited transmission system, and higher the data rate is, more the limitation is.
但是带宽有限的传输系统限制了数据率的迅速增长，而且这种限制作用随着数据率的增加而变得越来越严重。

We analyzed the theory origin, main features and limitation of rate-of-return regulation in USA and price-cap regulation in UK in this thesis, and compared their difference and similarity.
