The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

5岩芯沉积物中热液源组分携带的稀土元素组成具有类似海水的分布模式，反映了热液流体喷出海底后与其它物源物质之间的复杂的相互作用：一方面大量生物和陆源碎屑物质的快速沉积导致溶解态的热液源物质被快速清扫，无法向外扩散，快速堆积在热液喷口附近；另一方面，随热液羽状体向外扩散的颗粒态热液源物质也清扫海水中的元素共同进入沉积物。

Along with seawater stress strength upward, the ratio of root to shoot, Na+, Cl- and soluble sugar contents were increased significantly. Under the 10% and 20% seawater treatments, chlorophyll contents have no obvious difference compared with the control, but significantly decreased when the seawater stress further increased. Under the 10% seawater treatments, K+ contents in the shoot and root of Lactuca indica seedlings have no distinct difference compared with the control, but along with seawater stress strength upward, K+ content were markedly decreased by degrees. However, soluble protein content first increased then decreased with seawater concentration augment.
