循环地

Since any n x n doubly stochastic circulant matrix has a unique representation as a polynomial of degree n - 1 in the shift operator wn, the classification problem of primes in the doubly stochastic circulant matrices can be reduced to the solution of an equation over a doubly stochastic circulant matrix.

由于任一n阶双随机循环矩阵都可以唯一地表示为移位的n-1次一元多项式，从而可把双随机循环矩阵中素元的分类问题简化为解双随机循环矩阵上的一个方程。

In this part some countries and areas such as the United States, Canada, Japan, South Korea, European Union, and China are purposedly selected to be studied about the legislative purposes of circular economy, and also give a subjective evaluation after comparing and analyzing. The contrast and analysis lead to this conclusion that the legislative goals of circular economy in western countries give better expression to the concepts of circular economy, while in China's legislation of circular economy, too much stress is laid on the resources and economic interest of the environment, more attention is paid to exploiting and utilizing natural resources, meanwhile the environmental functions and values of natural resources are usually ignored.

该部分有针对性地选择了美国、加拿大、日本、韩国、欧盟和中国等国家和地区的循环经济立法目的进行了考察，通过对比分析，本文认为，西方国家在循环经济立法目的设计上比较好地体现了循环经济理念，我国循环经济立法在目的性规定方面，表现为过分注重环境的资源属性及其经济价值，强调如何合理开发利用资源，而往往忽视资源的环境功能及其环境价值。

This process organically combines the circulating fluidized bed combustion technology with boiler-front low-temperature dry distillation technology, the hot ash of circulating fluidized bed is used as the hot carrier to pyrolyze the coal and generate tar and gas.
