It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

The temperature rising mechanisms of manganese carbonate fines containing coal by microwave heating were discussed. The results show that, manganese carbonate fines containing coal have good characteristics of microwave heating and self-reduction. At the molar ratios of C atom to O atom as 1.1, 1.2 and 1.3 in the mixed materials, the averaged maximum temperature-rising rate of the mixed materials by microwave heating is 140.7 K/min at 1 473 K with the microwave frequency of 2.450 GHz. At the different containing coal ratios and heating temperatures, the value of the dielectric constant is big, 5.5, but that of the permeability is about 1, so the mixed materials belong to dielectric loss. The temperature rising performance depends chiefly upon the electromagnetic performance of materials, whose change is caused primarily by the chemical reaction, the changes of crystal structural , and the changes of defects state. The bigger the containing coal ratio, the better the absorptivity of microwave. At the same containing coal ratio, the higher the heating temperature, the weaker the absorptivity of microwave.

研究结果表明：含碳碳酸锰矿粉具有优良的微波加热特性和自还原性；在微波加热频率为2.450 GHz、碳氧原子摩尔比分别为1.1，1.2和1.3时，微波加热混合物料至1 473 K的升温速率平均最高达到140.7 K/min；不同的加热温度和配碳比下混合物料的介电常数较大，都在5.5左右，而磁导率为1左右，属介电损耗型；微波加热含碳碳酸锰矿粉的升温性能主要取决于含碳碳酸锰矿粉的电磁性能，而电磁性能的改变主要是由物料加热过程中产生的化学反应、晶体结构变化及缺陷状态的改变引起的；配碳比提高，物料吸收微波的能力有所提高；在相同的配碳比下，加热温度升高，吸收微波的能力有所减弱。
