求翻译：对JPEG压缩过程中量化后的 DCT系数块进行统计分析发现，在量化后的 DCT系数块中，绝对值为1的DCT系数大部分位于中低频范围。是什么意思？

Jpeg compression dct coefficients block quantized process for statistical analysis found that in the quantized dct coefficient block, located in the absolute value is 1 dct coefficients of most of the low frequency range.

In the process of quantifying JPEG compression DCT factor blocks after the statistical analysis found that, in the quantitative DCT factor after the block, an absolute DCT factor of 1 in most of the low frequency range.

The quantification DCT coefficient block carries on the statistical analysis discovery after the JPEG compression process in, in the quantification DCT coefficient block, the absolute value is 1 DCT coefficient majority of is located the low frequency scope.

During JPEG compression block of quantized DCT coefficients after statistical analysis found that, after the quantization of DCT coefficients in the block, most of the DCT coefficients of absolute value 1 is located in the low frequency range.
