| 8. | The results of these work indicated that som in top soils and sediments are highly heterogeneous and conprise a wide range complex organic matter such as humic acid , kerogen , and black carbon , and som have a nice bit of black carbon
综上所述，表层土壤和沉积物中的有机质是高度非均质的，包括腐殖酸、干酪根和碳黑，并且碳黑具有相当高的含量。碳黑在来源、性质和结构上不同于腐殖酸和干酪根，它是生物体和化石燃料不完全燃烧产生，具有更加稳定的性质和结构。 |
| 9. | Now design efficiency of common gas boiler can reach 90 percent or so , but various factors such as load , fuel quality , work condition and pressure which result in uncompleted burning of gas and excess air , decrease boiler hot efficiency and cause resources waste and environment pollution . considering these it is essential to adopt closed loop feedback control to boiler burning system
现今，一般的燃气锅炉设计效率均能达到90 %左右，但在实际运行中，因负荷、燃料品质、工作环境、压力、混合情况等因素的影响，往往造成燃气不完全燃烧或空气过量，使锅炉热效率降低，造成能源浪费与环境污染，在这样一种背景下，有必要对其燃烧系统进行闭环反馈控制。 |
| 10. | There are 3 parts of heat loss for gas boiler , including heat emission loss , uncompleted burning loss and fume hot loss , uncompleted burning loss decreases following the increase of excess air coefficient , while fume hot loss increases . it is obvious that there exit an optimum coefficient of excess air which make boiler own highest efficiency which is the purpose of burning control
不完全燃烧热损失随过量空气系数的增大而减小，而排烟热损失随过量空气系数的增大而增大，不难看出，存在一最佳的过量空气系数使得两者之和最小，即使得锅炉的热效率最高，燃烧控制的目的即在于此。 |
