关于表整数为算术数列中k个素数的乘积
This paper presents the number n of representations of the nonzero integer z∈Z-2 as the difference of two squares of integers in Z-2,and the number n of representations of the nonzero integer z∈Z-2 as(z=(x~2+2y~2)),where x,y∈x~2+2y~2.
给出了[-2]中的非零整数表示为[-2]中的两整数平方差的表示种数,还给出了[-2]中的非零整数表示为x2+2y2(其中x,y∈[-2])形式的表示种数。
This paper utilizes the Reciprocal Law Two Times to prove that the rational number of a kind of form is not the integer,and proves that the number of another kind of prime is limitless.
利用二次互反定律证明了某类形式的有理数不是整数,并且证明了某类形式的素数的个数是无限的。
This paper proposed an integer-to-integer shape adaptive discrete wavelet transform(ISA-DWT) coding scheme for the MRI.
本研究提出一种新的ISA-DWT(整数到整数的形状自适应离散小波变换)的核磁共振(MR)图像压缩算法,对变换后的系数采用适合于形状自适应离散小波变换的修改的SPIHT算法进行编码,并增加上下文自适应算术编码以提高其压缩性能。
