植物染料

For some dyes, the dye concentration of less than 1ppm in receiving water bodies is highly visible, so that even small quantities of dyes can color large water bodies. This not only affects aesthetic merit but also reduces light penetration and hydrophyte photosynthesis. In addition, some dyes or their metabolites are either toxic or mutagenic and carcinogenic.

某些染料在浓度低于1ppm时就能使接受水体明显着色，所以即便是少量的染料也会污染大面积水体，这不仅影响了水环境的美观而且会减少水体透光量，进而影响水生植物的光合作用，况且，有些染料或其降解产物有毒，甚至能诱发基因突变或致癌。

The indigo plant or the blue dye obtained from it.

靛蓝一种从木蓝属植物中得到的蓝色染料，或是人工合成的蓝色染料

In order to improve the dyeing properties of the plant indigo dye, the optimum ultrasonic dyeing process of pure cotton fabric with the plant indigo dye is determined through the orthogonal experiment, and the effects and mechanism of ultrasonic wave on dyeing properties of the plant indigo are investigated.

为提高植物靛蓝染料的染色性能，通过正交试验确定了超声波对植物靛蓝染料染棉织物的最佳染色工艺，探讨了超声波对植物靛蓝染料染色性能的影响及其作用机制。

Mangrove English word, derived from Spanish mangle, American Indians Taino language was originally called transliteration of the red dye, which dyes are from mangrove plants, the Spanish "mangrove" and English "bush" Combined, they form the word of mangroves.

英文mangrove一词，源于西班牙语mangle，原是美洲印地安人泰诺语红色染料称呼音译，而这些染料均来自红树科植物，西班牙文的"红树"和英文的"树丛"组合，就形成了红树林一词。

Natural Substantive Colours.—Indigo, one of the most valuable dyes, is the product of a large number of plants, the most important being different species of indigofera, which belong to the pea family.

天然直接染料——最宝贵的染料之一的靛蓝，是多种植物所产生的，其中最重要的是属于豌豆科靛蓝属中一个特殊的品种的植物。

Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.

使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵，从古时起，人们就知道从植物或者动物产品中提取天然染料。这周，我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说，就是用洋葱皮来染羊毛。这一例子中，用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是，媒染是来天然的，比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦，来交换多一点点的幸福

Modern, manufactured deys can be costly. Natural dyes form plant and animal products have been used since ancient times.

现代的人造染料会比较贵，而从动、植物提取的天然染料在远古时期就已被使用了。

These techniques were applied primarily to yellow-dyed textiles and to plant dyestuffs that contain yellow dyes, most of which are glycosides that are hydrolyzed by the strong acid used in earlier studies.

这些技术主要适用于黄色染色纺织品和染料植物含有黄色染料，其中大部分是糖苷水解是由强酸中使用的早期研究。

Acids are chemical compounds that, in water solution, have a sharp t aste, a corrosive action on metals, and the ability to turn certain blue ve getable dyes red.

酸是一种化合物，它在溶于水时具有强烈的气味和对金属的腐蚀性，并且能够使某些蓝色植物染料变红。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
