They often said if thetie-dye commodity that they buy does not fade, they will request to return the goods, because they think the tie-dye commodity that does not fade is not made of natural plant isatis root.

我们自制的扎染品，尤为韩国和日本人喜爱，他们常说如果他们购买的扎染商品没有脱色现象，他们会要求退货，因为他们认为不褪色的扎染制品就不是天然植物板蓝根染成的。

Laccases are able to oxidise both phenolic and nonphenolic compounds. They have broad ranges of subsrate specificity. Therefore, they are very useful for applications on pulp bleaching, textile dye decolouration, effluent detoxification, bioremediation and biosensors.

由于漆酶能够氧化芳香类化合物和其它一些非芳香类有机物，具有广泛的底物特异性，因此在纸浆漂白、纺织品染料脱色、有毒废弃物的去除、生物修复和生物传感器等方面具有巨大的应用潜力。

The inorganic and organic polymolecular flocculants commonly used at present have caused some problems such as inferior performance, secondry pollution and so on. Therefoer, the study of new kind of flocculant is a pressing and meaningful task.

0引言絮凝剂是一类可用来有效凝聚、沉降引起水污染的不易沉降的固体悬浮颗粒和胶体颗粒的物质，已广泛应用于工业废水处理、发酵工业预处理和食品工业中的澄清、脱色等方面[1]。

ABSTRACT Polysilicate aluminum and ferric saltflocculant was prepared from coal refuse and pyrite slag, and was used as flocculant in the treatment of dyeing wastewater for removing turbidity and COD and decolorizing.

摘 要 研究利用煤矸石及硫铁矿烧渣作原料制备PSAAF并用于印染废水的处理。结果表明，PSAAF有良好的除浊、脱色和除COD性能；尤其对亲水性染料，具有独特的去除效果。

The decolorization mechanism,which comprises the formation of unstable compunds with hydrolytic aluminium ions and ferric ions and conglomerating with polysilicic acid in the flocculant,was proposed.8figs.,1tab.,12refs.

PSAAF的脱色机理是水合铝、铁离子的凝聚作用和聚硅酸的絮凝而产生的共沉淀。图8，表1，参12。

Flocculants in wastewater treatment has become increasingly widely used, in which high-performance composite coagulant in water treatment technology occupies an important position, to that end, research synthesis of a new type of high-performance composite PFS purificant PISC, and dying, coal washing, paper and municipal sewage and other industrial wastewater purification experiments confirmed that the water purification agent with the exception of turbidity, detreated reduce COD, BOD5 and SS functions.

在废水处理方面絮凝剂已越来越广泛地被应用，其中高效复合混凝剂在水处理技术中占有十分重要的地位，为此，研究合成了一种新型的高效复合聚铁净化剂PISC，并对印染、洗煤、造纸和城市污水等工业废水进行净化实验，证实该净水剂具有除浊、脱色、降低COD、BOD5及SS的功能。

The type and concentration of thiophenic sulfur in gasoline and diesel fuel were determined separately by gas chromatography with a sulfur chemiluminescence detector.With activated carbon and 30％aqueous solution of H2O2 as catalyst and oxidant respectively, the experimental studies of oxidative desulfurization of gasoline and diesel were carried out.

采用气相色谱-硫化学发光检测器分析了汽油和柴油中噻吩类硫化物的分布及浓度；以活性炭作为催化剂，以30％过氧化氢溶液为氧化剂，在甲酸存在条件下考察了汽油和柴油中噻吩类硫化物催化氧化脱除的选择性，讨论了硫化物中硫原子电子密度对硫化物氧化选择性的影响。

In this article, three representative oil and fat resourse (edible raw oil, unedible linseed oil and waste oil and fat) were used to study the fatty acid methyl ester preparation technology, and the products from different technologies were compared and analysed. For plant oil, ester exchange process was performed immediately after simple decolorating and alkali refining pretreatment.

对于植物油脂，采用简单的脱色、碱炼预处理后，直接进行酯交换的工艺；对于废油脂，由于其成分变质较严重，预处理也显得相对复杂，采用了先预酯化再酯交换的工艺和先皂化酸化后再酯化的两种工艺。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
