Therefore, the nickel impurity in the chromium-plating bath was determined using spectrophotometry, which was based on the reaction between nickel ions and diacetyldioxime, generating a red complex, in the presence of alkali and ammonium per-sulfate. The measurement was carried out in 3cm color-matching cells at a wavelength of 510nm, using the sample without chromogenic agent as the reference.

在碱性和过硫酸铵存在的条件下，镍离子与丁二酮肟生成水红色配合物，利用这一特性，以丁二酮肟光度法测定镀铬溶液中镍杂质的含量，以不加显色剂的试样作参比液，用3cm比色皿，在波长510nm处测定。

Can with water, alcohol and ammonia reaction, difference generate acids, esters and amides, the reaction rate than the corresponding ester and anhydride fast.

可与水，醇和氨反应，分别生成酸、酯和酰胺，反应速度比相应的酯和酸酐快。

Newly spawned widows feed on krill and copepods, while older species feed in the water column on gelatinous zooplankton, crab, some amphipods, krill, and small fishes.

新生成的遗孀饲料 krill 和桡足类，而凝胶浮游动物、蟹、 amphipods、 krill 及小鱼上的水列中的较旧的物种饲料。

In chapter 2,the bi-electrophilicity ofα-CAPAs(Gly-CAPA,Ala-CAPA) was identified by the isotope analysis ~(18O,~(15)N and furtherproved by trappingα-CAPA with nucleophiles such as water,amino acids,phosphateand methanol in alkaline media which yielded phosphorylated products,namely,theNPAAs and N-(mono-substituted)phosphoryl amino acids.

同时，CAPA和亲核试剂如水，氨基酸，磷酸和甲醇分子反应可以生成各种磷酰化产物，如NPAAs和N-磷上单取代的磷酰化氨基酸。

The research result about abnormal pressure shows insufficiency of compaction disequilibrium as the sole cause of high pore fluid pressures, and tectonic compression, aquathermal expansion, diagenesis, hydrocarbon generation etc also can be the generating mechanisms.

一般认为欠压实是最主要的异常高压成因机制。由于构造挤压引起压应力的改变，由于水热膨胀、成岩作用、烃类生成等引起体积的膨胀，或由于流体流动和浮力作用也可产生异常超压。

Based on thermal analyses, thermal decomposition mechanisms were predicted that at the first step the polymer lost two coordination water molecules and at the second step lost two formates companied by the formation of some kinds of materials.

根据热分析，推测该配位聚合物的热分解机理为：在第一步失去两个配位水，在第二步失去两个甲酸根并伴随着某种残余物质的生成。

The results of experiment show that separate addition of mineral admixture (ground fly ash, slag fines, silica fume) into concrete can improve its resistance to chloride ion penetration and diffusion.

从机理上分析，矿物掺合料的火山灰效应改善了混凝土中水泥石与集料之间的薄弱界面，降低孔隙率，使孔细化，同时生成更多低碱度的C-S-H凝胶增加混凝土的Cl-固化能力，从而提高了混凝土抗氯离子渗透能力。

The net cement with bentonite can form hydrogen key which can improve the felt of the systematic and are wail for eventual strength; The main mechanism of J-85 accelerator to accelerate concrete coagulating are in alkalescence condition to make aluminate and gypsum link and block the building of calcium and aluminium sulphate around cement granule; Polypropylene acid can improve early strength of cement through altering the thickness of hydroxide in cement grout.

添加膨润土后的水泥净浆中形成了氢键，提高了体系的粘结性，对后期强度发展有利； J-85速凝剂加速混凝土凝结的主要机理就是在碱性条件下，使铝酸盐和石膏结合，阻碍水泥颗粒周围的硫铝酸钙即钙钒石的生成，从而使水泥迅速凝结；聚丙烯酸通过改变水泥浆体中羟基的浓度从而提高水泥试块初期强度。

The maters in the surface of the strip were mainly elemental sulfur and silver.

燃料中的其它硫化物，燃烧后会生成二氧化硫，在有水的情况下，也会造成对金属的腐蚀。

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.

结果表明：MgO和α－甲基丙烯酸配合可增稠环氧树脂，随着MgO加入量的增加，环氧树脂增稠的速度加快；MgO与α－甲基丙烯酸为3：1时，增稠环氧树脂的效果较好；推测环氧树脂的增稠机理是α－甲基丙烯酸中的端羧基与氧化镁反应，放出热量促使其端羧基与环氧树脂中的仲羟基反应，上述反应生成水产生的氢键和羰基与氧化镁中的金属原子形成络合物共同导致环氧树脂的粘度增加。
