Meanwhile , the importance of different ecosystem services in urban areas is different . the function of fixing carbon and releasing oxygen is the most important , the function of conditioning climate is the second , and the functions of keeping waterhead , preserving soil , purifying environment , and restraining noises are the last important 同时,城市生态系统各生态服务功能的重要性,由大到小依次为固碳释氧功能调节气候功能涵养水源功能保持土壤功能净化空气功能与减弱噪声功能。
This flexion of graph can be defined as criterion of coal ignition character under excessive oxygen supply . based on viewpoints of coal ignition , we put forward assumption aiming at ignition character of coal with excessive oxygen . in this thesis , with comparison of average temperature increase among eleven kinds of coal , the following are obtained : homogeneous ignition happens when coal has higher volatile matter and there is a approximative direct - ratio relationship between temperature hoist before flexion and content of volatile matter ; on the other side , heterogeneous ignition occurs for the coal with lower volatile matter content because of collective influence of volatile matter and fixed carbon combustion , and one - to - one relationship between temperature increase before flexion and content of volatile matter does not exit 以煤着火性质研究的观点为基础,对煤在过氧条件下的着火性质提出假设,通过11种标准煤样在过氧条件下燃烧实验,对比了拐点前后平均温升与煤样成分的关系,证实了挥发分含量较高的煤在过氧条件下发生均相着火燃烧,拐点前后量热系统的温升分别与挥发分和固定炭的含量成近似正比的关系;而挥发分含量较低的煤在过氧条件下发生非均相着火燃烧,拐点之前量热系统的温升由于受到挥发分和固定炭同时燃烧的影响,因而不存在温升与挥发分含量之间单一的对应关系。
