Under the guidance of systematology, this paper take advantage of a research method of combining development analysis and comparative analysis qualitative analysis and quantitative analysis, theoretical analysis and positive analysis. In the background of urban construction, it is intended to build a frame about study of city's sustainable development from symbiosis theory.

在研究过程中，本文借鉴了城市经济、可持续发展、共生理论等领域已有的研究成果，以系统思想为指导，采用定性分析与定量分析相结合、归纳与演绎相结合、理论分析与实证分析相结合等方法，以城市化为背景，建构了我国城市可持续发展过程中建立共生关系的研究框架。

Say you want a 2D table of values, initialized as zeros.

比如说你用一个二维表格来存放数据，全部先初始化为0。

The origin of the almighty dollar is in what is now the Czech Republic. In 1519, a silver mine near the town of Joachimstal began minting a silver coin called, unimaginatively, the Joachimstaler. The coin, which was circulated widely, became better known by its clipped form, the taler.

至高无上的美元起源于现今的捷克共和国。1519年，位于Joachimstal镇附近的一座银矿开始制造银币，银币的名称，不假思索的取名为Joachimster，这种银币广泛流通，后来名称简化为"taler"，变的更加有名。
