REF〓-NaF-LiF molten salt can be employed to electrolyze La-Nd-riched alloy.

提高钠锂比有利于RE〓O〓在REF〓中的溶解，有利于挥发损失和表面张力的降低，但对物质的电导率不利。

Air dryer is a mechanical equipment which can make the moisture(generally means water or other evaporable liquid) in material change into vapor and evaporate by heating, so that the solid material can reach the required humidity ratio.

空气干燥器是通过加热使物料中的湿分(一般指水分或其他可挥发性液体成分)汽化逸出，以获得规定湿含量的固体物料的机械设备。

There were not correlation between the inter-colony agonistic behavior and the secretion of frontal gland, gnathal gland and abdominal gland, or the compounds of body wall, the genetic background, the contents of microelement and protein in body, the microorgansim in intestinal cavity. The colony age and the colony individuals quantity had not effects on the inter-colony agonistic behavior. But the season change, the food kinds, the soil around colony, and the weak volatile compounds from termites would influence the agonstic behavior between colonies in a certain extent.

巢间个体的格斗行为与额腺、颚腺和腹腺分泌物组成、表皮化合物组成、遗传背景、体内微量元素和蛋白质含量及体内肠道微生物的存在与否无关，巢龄和巢群大小对格斗行为也无影响，但季节变化、食物种类、供饲土壤和体表挥发物对格斗行为有一定的影响。

The micelle granules were accumulated in the guttate structure. Both liquid crystal phase and isotropic phase coexisted here. With the volatilization of solvent, the structures can change from disc or hexagon to cube with the variation of environment and interior reciprocity.
