本发明公开了一种对海水化学需氧量进行测定的光度测定法，该方法首先将海水样品进行预处理，再以碱性高锰酸钾为反应体系，这样海水中的有机物在强碱性介质中与过量的高锰酸钾迅速反应，高锰酸钾被有机物定量还原后生成锰酸盐，以纯水或空白溶液作参比，在锰酸盐的最大吸收波长430nm处测其吸光度A，该吸光度A与海水样品中的有机物的含量具有正相关关系。

The severe seawater intrusion exists in certain eel farming factories within Changle, Fuzhou, in certain prawn farm within Jiuzhen county, Zhangzhou, and in certain saltern within Xiuyu district, Putian, all belonging to seawater intrusion in human activity areas. The maximum concentration of Cl and mineralization within those severe intrusion areas are 5629.00 mg/L and 33.16 g/L respectively. The slight seawater intrusion is monitored in Quangang district, Quanzhou, where natural conditions are kept. No seawater intrusion is monitored in Dongchong peninsula, Ningde. No soil salinization is monitored except Zhangzhou where the sand is slightly salinized.

在福州长乐市近岸某鳗鱼养殖片区、漳州漳浦县近岸某对虾养殖片区、莆田市秀屿区某盐田附近监测到严重海水入侵，均属人类开发活动影响区域内的海水入侵，严重入侵区域氯度最高达5629.00 mg/L，矿化度最高达33.16 g/L；在泉州市泉港区某自然村监测到轻度入侵，属自然状态下的海水入侵；在宁德东冲半岛外浒沙滩附近未监测到海水入侵；在漳州断面监测到土壤盐渍化，为轻度盐渍化土，其他断面为非土壤盐渍化土。

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。

As a result, the DNA segment of predicted size, about 372 bp, appeared in the two kinds of vibrio, but didn't appear in the others. Therefore, a rapid detection kit for V. alginolyticus was developed successfully. It could provide a quick, exact diagnosis and detection method for the diseases in aquatic animals and human beings, and also for the aquatic food security caused by V.alginolyticus. 3. Furthermore, this detection kit was used to investigate the distribution of V.alginolyticus in seawater of living area, healthy aquicultural seawater ...

此外，我们利用此试剂盒对海南地区的生活区附近海水、水产动物养殖健康区海水和发病区海水进行了溶藻弧菌存在情况的调查，结果显示，生活区附近海水的溶藻弧菌数明显低于水产动物养殖健康区海水和发病区海水，后两者中又以发病区海水的溶藻弧菌数量最多；无论是在水产动物养殖健康区还是在水产动物养殖发病区，养殖场的进水处海水中溶藻弧菌的数量也明显低于养殖池水中的数量。

Sea water is strong erosive fluid and there are many halobios which also corrosive materials, so it is necessary to select corrosion resistant materials that make sure the operating safety and reduce the fist cost of the system.

海水化学成分复杂并含多种海洋生物，对材料具有很强的腐蚀性，为保证海水制冷热泵系统的安全可靠，并尽量降低海水制冷热泵系统的初投资，耐海水材料的选用十分关键。

The trend of seawater is that the intrusion area varies as following rule: small to big to small to big, and the causation of seawater intrusion is the appropriate hydrodynamic and hydrogeological condition, and the main reason is that human activities change the groundwater hydrodynamical condition.

海水入侵的趋势为：海水入侵面积有小；大→小→大的变化规律：海水入侵的成因是具有了水动力条件和水文地质条件，而人为的改变地下水动力条件是发生海水入侵的主要原因。

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.

结果表明：苦荬菜幼苗地上部受海水胁迫较为显著，而根在30%海水以内与对照相比没有显著差异；根冠比随着海水比例的增加而提高；10%和20%海水处理下，叶绿素含量与对照相比差异不显著，但随着海水浓度的进一步增加，叶绿素含量显著下降；10%海水处理下，苦荬菜地上部分及根K+含量与对照差异不显著，高于10%海水处理，K+含量随海水比例的增加地上部和根部均逐渐显著降低；海水处理下，体内Na+和Cl-含量逐渐显著增加；地上部可溶性糖逐渐显著增加，而可溶性蛋白呈先升后降。
