实数运算的英文

例句与用法

1. Perhaps , but at some point , i must deal with the fact that real number arithmetic is not exact on digital computers
   也许，但在某种程度上，我必须处理实数运算在计算机上是不精确的事实。
2. Due to the real operations and the fast dht algorithms utilized for the fast computation of the rdgt , the parallel lattice structures of the rdgt can more easily be implemented than in the cdgt case
   这种方法由于仅涉及实数运算，并可借助于快速离散hartley变换算法，从而使rdgt的并行格型结构实现比cdgt要简单得多。
3. It is shown that , due to the real operations , the computation of the bi - orthogonal analysis window , the transforms coefficients , and the reconstruction of the original signal in rdgt case , can be significantly reduced as compared with the computation of those in the cdgt case . and the similarity between the rdgt and the discrete hartley transform ( dht ) allows the rdgt to utilize the fast dht algorithms for fast computation . meanwhile , the rdgt bears a simple relationship with the cdgt such that the cdgt coefficients can be directly computed from the rdgt coefficients
   主要内容有：研究了一维和二维实值离散gabor变换( rdgt )方法，这种方法由于仅涉及实数运算，并可利用快速离散hartley变换算法加速变换，因而在计算双正交分析窗、变换系数以及信号重建方面都比复值离散gabor变换( cdgt )简单易于实现，并且rdgt系数与cdgt系数的实部和虚部有着非常简单的关系，因此前者的计算完全可以替代后者的计算，从而达到明显减小gabor变换计算量的目的。
