大幅度下降
例句与用法
- 4 . the study on pore structure shows that the incremental pore size of hbc concrete ( 3d , 7d ) is relatively larger , approximately equivalent at 28d , but smaller at 90d and180d compared with opc concrete . the harmful pore of both hbc and opc concrete decreases sharply but little harmful and harmless pores increase greatly , especially the harmless pore whose pore size is less than 20nm for hbc concrete increases much more than opc concrete , which can explain why hbc concrete possesses excellent long term properties

这一方面是因为使用经小波压缩后的信号作为神经网络的输入，压缩后的信号不仅提取了原信号中的特征信息，而且使网络输入的数据点数大幅度下降，大大提高了网络的运算速度。另一方面，由于选用了较高次分解所得的高频部分作为网络输入，从而即使在原始信号中含有较高的嗓音时也能获得较高的预测准确度。因此，将具有压缩功能的小波变换与神经网络相结合的方法必将得到广泛的应用。 - The tax rebate rate dropped greatly after june , 01 , 2007 . the rate of ours decline from 11 % to 5 % , and the price ? for ? this kind of products has been increased ? 6 % to 10 % widely . in order to cooperate smoothly with this order , we did not increase the price but according to tat which we have beening offer you for three months . so please kindly understand that we can not give you discount , please provide your kind understanding on this
