Soils from the study sites show the typical characteristics of an Andisol, being strongly acidic, with fewer exchangeable cations, a low base saturation, and an accumulation of soil organic matter with Al-compounds which are recalcitrant to decomposition. Therefore, the effects of vegetation types on the contents of SOM, TC, TN, and CEC were not significant.

本试验区为典型的火山灰土壤，土壤呈极强酸性，可交换性阳离子浓度与盐基饱和度极低，加以腐植质与活性铝形成不易为微生物分解的复合物，造成大量有机质聚积，因此不同天然植被对土壤有机质、碳氮浓度及CEC之影响均不显著。

The result of study on physical and chemical properties of sewage sludge compost showed that sewage sludge compost contended plenty of organic matter and plant nutrient, its CEC and PH is fit to plant growth, but its EC and content of heavy metals were too high for plant growth.

污泥堆肥理化性状研究表明，污泥堆肥中有机质、营养元素含量较高，阳离子交换量和PH值较适宜，能满足大多数植物的要求，存在的主要问题是电导率和重金属含量过高。

The effect of controlling microstickies in recycled newspaper pulp and the effect on the resultant paper property of some fixatives,including inorganic polyaluminum chloride,organic polyamine,polydiallydimethyl ammonium chloride,and high cationic starch,were investigated in this paper.

分别以聚合氯化铝、聚胺、聚二甲基二烯丙基氯化铵和高取代度阳离子淀粉作为固定剂，研究了它们对废纸浆中微胶黏物的控制效果及对纸页性能的影响。

All these compounds contain hydroxy groups and can be used as hydrophilic chain-extenders in the synthesis of cationic polyurethane ionomers.

这些化合物（或与含三羟基的化合物配合使用），可以作为季铵阳离子型聚氨酯离聚物的扩链剂。

Brix pear juice was treated with FPC-21 resin to reduce the pH value to 4.05, then treated with XAD-16 resin to rise color value (T 440) up to 85%, and concentrated to 70 °Brix. The color value of PJC is over 45% after storing at 37℃ for 35 d, which can meet the export regulation.

采用阳离子树脂处理将酥梨汁的pH值降低为4.05，再经吸附树脂将色值提高为85%，浓缩至70 °Brix的酥梨汁在37℃下贮存35 d后，色值仍大于45%，符合出口要求。

During the first stage of the thermodegradation in nitrogen, the thermal stability of EVA /clay nanocomposites decreases din to the decomposition of octadecyl ammonium and a catalytic effect of acidic sits on the clay lavers deriving from the decomposition.

实验结果表明，通过离子交换反应，可使长链十八胺阳离子嵌入粘土片层间，增大了粘土的片层间距；对于EVA/有机化粘土体系，通过熔体插层可使EVA分子链插层于粘土片层中，使粘土片层被进一步撑开；EVA/粘土纳米复合材料具有较好的力学性能。

The existence of such centers. is attributed to defects in crystals resulting from isomorphism between cations of different valences.

阳离子不等价类质同象造成的晶体缺陷，是使其具有电子-空穴心的内在因素。
