The invention discloses a method for measuring seawater chemical oxygen demand by photometry, wherein the seawater exemplar is first pre-processed, then using the basic potassium hypermanganate as reaction system, the potassium permanganate is deacidized quantitatively by organics to produce manganate, using pure water or margin solution as reference ratio, measuring the absorbance an of the manganate at its maximum absorbing wave length 430 nm, drafting the A-COD value operating curve, obtaining the concentration of the organics in the water, i.e.

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 main raw material for producing magnesium carbonate and magnesium are magnesite, dolomite and bitten, which have abundant reserves in our country, especially the reserves of magnesite and dolomite, that not only holds the domain position but also has superior quality in the world, which establish the massy material developing foundation of magnesium industry.

但我们也应该看到虽然我国具有发展镁盐产品的优越条件，但因目前绝大部分现有生产厂家均属乡镇企业，资金有限，生产规模小，设备陈旧，技术力量薄弱，提高产量及质量的能力受到限制，且生产的品种单一，使我国镁盐的生产仍处于粗制初级、原料性产品的阶段，远不能满足国民经济发展的需要，高档、功能化产品仍需从国外进口，出口产品的价格只有进口产品价格的几分之一。

By analyzing the result of these experiments, we realizing that the solvent is very essential in the controlling of the crystallizing and the melting salt works as solvent is possible, and we proposed the idea of operating chemical metathesis synthesizing in melting salt.

通过对实验结果的分析，根据溶剂对于纳米晶粒生长的重要性和熔盐作为溶剂的可能性，我们提出了熔盐中的化学交换法的思路。

After sodium bisulfite reacted with methanal at 60-65℃ for 0.5h, aniline was dripped into the system to synthesize phenylaminomethyl-sodium sulfonate subsequently, the diazol solution of p-nitroaniline was dripped into phenylaminomethyl-sodium sulfonate synthesized to form 4'-nitro-4-aminoazobenzene. The compound was then added into diazol solution of p-chloroaniline to obtain the object product, which was identified by IR spectrum and element analysis.

在60~65℃温度下，亚硫酸氢钠与甲醛反应半小时之后滴入苯胺生成苯胺基甲基磺酸钠，另将硝基苯胺重氮化得到重氮盐溶液滴入苯胺基甲基磺酸钠中得到4'-硝基-4-氮基偶氮苯，然后将其滴入氯苯胺重氮化后的重氮盐溶液中，得经红外光谱检验和元素分析证实的目标产物。

Owing to the good stability in light, heat and chemical characteristics, the rare earth-doped molybdate is a good kind of luminescent material, but there are few reports on it.

稀土钼酸盐发光材料由于具有良好的光热稳定性和化学稳定性，是一种很好的发光基质材料，但关于稀土钼酸盐发光材料的研究却少有报道。

The results indicated that the inhibition efficiency increased with increasing molybdate concentration, but single molybdate inhibitor had low inhibition efficiency.

实验结果表明：单一钼酸盐对海水中碳钢的缓蚀率随着钼酸盐使用浓度的增加而增加，但低浓度使用缓蚀率较低。

It is obviously that the content of water of soils could influence the growth of plant and the physical character of soils. With the planting salt-enduring plants, mucosity of soils getting more reduced and porosity of soils getting more improved.

种植耐盐植物后的土壤中的含水量有明显提高，这主要是由于耐盐植物植入后，土壤的物理性质发生了相应的改变，土壤中粘粒减少，土壤孔隙状况比较好，使水分有较高的入渗率，这也是水分在改良后的土壤中积聚起来的一个原因。

As a result, there was stable accumulation on the saltmarsh, compared to frequent alternation of erosion and accretion in adjacent mudflat.

研究区潮流不对称性明显，主要表现为涨潮优势，且由光滩向盐沼上部不断增强，潮沼植物和地形变化是加强盐沼区涨潮优势的主要原因。
