查询词典 ion migration

The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.

从以上实验结果中我们可以得出以下结论：四君子汤总多糖具有促进IEC-6细胞增殖、迁移、粘附的作用；四君子汤总多糖无论是对IEC-6细胞增殖、或者迁移的作用均优于各单味药多糖，可能是各种单味药多糖综合作用的结果；多糖可能是四君子汤"益气健脾"药效的主要成分；小肠上皮细胞可能是四君子汤总多糖的作用靶点之一，提示临床采用四君子汤及"益气健脾"法治疗"脾虚证"的疗效机制可能与增强机体的整体免疫和肠道粘膜免疫功能有关。

The dir ection of calcium ion migration in tooth hard tissue is cementum→dentin→enamel .

牙体硬组织中钙离子的迁移规律为：牙骨质→牙本质→牙釉质。

Water-rock interaction demonstrates that, a gold-boring formation , i. e., a set of light metamorphic clastic gritstone, sandy slate, and tuffaceous slate in Wuqiang Runnel Formation, Ban Stream Group, act as the source of gold deposits in South-West Hunan. The gold is originally derived from volcanic eruption materials in Wuling-Xuefeng period; for the typical single gold deposit such as Mobin, which is short of sulphide, chlorine is very important in the metallogenic process; sulphur and chlorine perform as the major negative ions to form complex ions with Au throughout the gold activation and migration movement. The complex ion of chlorine and gold may keep stable in a wide range of temperature; the physical-chemical conditions in typical geothermal fluid system are of deciding significance for gold activation, migration and precipitation.

特定体系的水岩实验证实了漠滨及整个湘西南金矿的成矿元素Au和伴生元素主要源于赋矿围岩-板溪群五强溪组的一套浅变质碎屑砂岩、砂质板岩和凝灰质板岩；首次突破传统认识，证明氯在中低温热液体系中能与Au形成稳定络合物的形式进行运移，因此氯在本区Au成矿过程中起着相当重要的作用；成矿热液流体中Au主要以金硫、金氯络合物形式在溶液中迁移，阴离子∑S、Cl〓对金的活化、迁移及沉淀起主导作用，Au的伴生元素As、Sb在热液体系中与Au形成金锑、金砷络合物有利于金的进一步活化、迁移及沉淀；中低温热液流体成矿过程中，体系的物理化学参数对Au的活化、迁移及沉淀富集起决定性作用。

Iron oxides would continue to be formed or at least not to be dissolved under oxic conditions, and the sediments in brown to red color will then be dominant. While in a reducing environment, iron oxides will be dissolved, with the possible migration of iron ion in the ocean, and then buried as siderite, pyrite, or other ironbearing minerals.

氧化强氧化条件利于沉积物中氧化铁的持续产生或者至少保持不被溶解的状态，从而形成棕色-红色沉积物；还原条件利于沉积物中铁氧化物的溶解，形成菱铁矿、黄铁矿等形式的埋藏，并可能造成溶解铁在海洋内的迁移。
