The paper-like display that named electronic-paper is studied intensively in recent years. For the properties of digital driving, bistable information storing, portability and flexibility, Lambert' s reflection and wide visual angle, electronic paper will be widely used in the fields of display, decoration, electronic book, electronic newspapers and so on. So the market potential of electronic paper is great. Encapsulated electrophoretic ink is studied in this paper. Based on the preparation of electrophoretic liquid, the study is focused on the relationship between composition and properties of the electrophoretic ink. Most of the reported prototype electronic papers are based on the electronic ink colloidal suspension, which take the inorganic pigment titanox or silica as electrophoresis particle. The property of inorganic particle system is studied perfectly. There are less reports about organic pigment particle electrophoresis colloid. This paper focused on the system of organic pigment electrophoretic liquids is illustrated as follows: The colloidal suspension is the active and most crucial part of the eletrophoresis electronic paper. The adsorption of dyes on the surface of pigment was tested qualitative by thin-layer chromatography (TLC) for a series of dyes. The coloration of solvent dyes on microcapsule film was tested too. Combined with the spectrum of solvent dyes and pigments, the dyes of solvent Sudan Red series are selected. The spectrum and the zeta potential of different brand diarylide yellow pigment in mixed xylene and tetrachloroethylene were compared. The testing result shows that the C. I. PY14 which density matched to, and dispersed in, a solvent medium of tetrachloroethylene and xylene is the best one. The reaction between many charge control agents (CCA) and C. I. PY14 proved that the mechanism of PY14 charging is based on Lewis acidic-basic reaction. And the basic property of substituted amines was found by the zeta potential:(1) in the nopolar media colloidal system, primary is weak than secondary, and the third ethylamine is the stro ngest. (2) as to the longer chain substituted amines, the steric always lead to weaker basic. An imide-type copolymer namely polyisobutylene imide (PIBI) is a good CCA and stabilizer of C. I. PY14. The copolymer consists of a 100-200nm long hydrocarbon chain acts as a steric I part of the stabilization and an amine group which assists in the charging and adsorption mechanism of the pigment surface. All the components such as solvent dyes, CCA, pigment and dye were balled to produce electrophoretic ink in different ratio. The affecting of water to nopolar media electrophoretic ink was studied. It is found both water-based acid and base lead to the stability and zeta potential change of electrophoretic ink. The electrophoresis properties such as response speed, optic density and displaying density field were studied. The influence of CCA, dispersion of pigment and thicker of test cell to the display were also studied. Based on the above study, the electrophoretic liquid was optimized. It is found that ET-14 is a good stability of the electrophoretic ink and many electrophoresis properties were improved. The encapsulating of electrophoretic ink is one of the key technologies of electronic paper. Three microencapsulation techniques are used in this paper: the coacervation approach, the in situ polymerization and suspension polymerization. Many experiments were carried out to choose the better curing agent and better process. Conclusions were made that the microcapsule produced by coacervation features high transparency, good flexiblity, and the prepolymer of urea and formaldehyde is a good curing agent of gelatin and acacia. The binder was selected according to the property of microcapsule. High contrast displaying film of microencapsulated electrophoretic ink was achieved, and the electrophoresis property of the film was tested. It was found that the property of microcapsulated electrophoretic ink display is similar to the non-encapsulated electrophoretic display.

减速机一般用于低转速大扭矩的传动设备，把电动机.内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速效果，大小齿轮的齿数之比，就是传动比。

减速机是一种动力传达机构，利用齿轮的速度转化器，将马达的反转数减速到所要的反转数，并得到较大转矩的机构。

vat dyes can bring a little color to life. Most clothing is colored with dyes. Modern, manufactured dyes can be costly. Natural dyes from plant and animal products have been used since ancient times. So this week, we describe a natural way to dye wool. 染料可以给生活带来一些颜色。大部分的衣物是用染料来着色的。现代中人造染料可能很昂贵。来自动植物的自然染料从古自今一直被使用着。所以这周我们来描述一种自然染料染羊毛的过程。
The advice comes from information written by Jenny Dean of the Intermediate Technology Development Group in Britain. This anti-poverty group is now called Practical Action. 这篇报告所涉及的信息是jenny Dean所写，他是英国的一个叫做中级技术发展组织的成员。
There are several methods to put dye onto material. The vat method, for example, can be used to dye wool with onionskins. For this example, use one hundred 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 squeeze out the extra water. 把染料添加到物质中的方法有很多。比如，在染缸中的方法可以用在将羊毛染成洋葱皮染色的过程中。在这个例子中，用一百克天然羊毛。羊毛必须是干净的。在有肥皂水的水中浸泡一整夜。接着用清水清洗直到他有一点发热。轻轻的拧干他的水分。
A solution called a mordant is used in the vat dyes process. A mordant helps fix the dye to the material. Traditionally, mordants were found in nature. Wood ash is one example. But chemical mordants such as alum are popular today. Alum is sold in many stores. It is often mixed with cream of tartar, a fine powder commonly used in cooking. 一种叫做媒染剂的液体被用在染色过程中。媒染剂可以帮助染料与材料的结合。以前媒染剂实在自然界中被发现的。草木灰就是一个例子。但是化学媒染剂比如明矾在今天使用的很广泛。明矾在很多商店都有出售。它经常和酒石膏混合在一起，是一种用于烹调的细小粉末。
Mix eight grams of alum with seven grams of cream of tartar in a small amount of hot water. Add the solution to a metal pan of cool water. Next, add the wool and place the mixture over heat. Slowly bring the liquid to eighty-two degrees Celsius. Heat the mixture for forty-five minutes. After it cools, remove the wool and wash it. 将八克明矾和七克酒石膏用少量的热水混合在一起。将混合物放在装有冷水的金属盆中。下一步，放入羊毛将他们一起加热。使这种液体慢慢升至八十二摄氏度。当他冷却后，拿出羊毛并洗干净他。

他的怒和大臣的排法这个小故事，可以看出来在唐初世族的力量虽不像以前那样可以左右数个朝代，但任然有巨大的能量，而李世民发还重修天下姓氏谱，将皇室李姓排在首位，也是进一步打击世族阀门的一个小小政治手腕。显然,央行是希望通过此举为银行信贷打开阀门,以确保通过刺激消费和投资保持经济增速不大起大落。 不过,记者了解到,由于经济运行风险加大,企业信贷需求开始减弱,出于风险防范考虑,银行已经开始惜贷,贷款规模已不再是银行放贷的障碍。电子液压系统及部件，船用阀门遥控和液位遥测系统，液压驱动头电液驱动头，温控阀以及不同尺寸，不同用途的液压马达，种类繁多的塑料产品，还提供与激光光学相关的产品与服务。 普莱格船用技术 自1963年以来，普莱格船用控制系统已经广泛应用于世界上的数千条船舶。不锈钢管件卫生级阀门管件是哪些人采购,如果有人想要,请到我的阿里商铺来打我不会有私人自已去大批量采购这类东西的，一般应该是那些专业维修公司，或是装修承包商，或是物业管理公司等等会大批量采购。

适当增加多种维生素(含有叶酸胶囊的，或加上叶酸胶囊)，当然是天然的食品好。 均衡营养最好。最好多吃提高免疫力的、补脑的食品，避免感冒等。 例如，大蒜是抗癌之王!注意!吃法有讲究，必须先把它切成片，一片一片的薄片放在空气里15分钟，它跟氧气结合以后产生大蒜素，就生吃。但是医生没有给我开叶酸，让我自己到药店买。结果，可能是被美罗药方的忽悠了，给我介绍了宁波纽斯康出的叶酸胶囊，大概要69元一瓶。价钱贵一点倒无所谓了，不知道补充叶酸的效果怎么样啊? 叶酸又称维生素M，有抗贫血性能，可以降低神经管畸形的发生率。还有利于提高胎儿的智力，还是很有用的。具体要怎么吃那位朋友可以告诉我吗? 是因为先兆流产才要用"黄体酮胶囊"的吗?如果是的话，推荐你可以去医院打"绒毛膜促性腺激素"，或是打针剂的"黄体酮"因为这些是纯天然的没有什么添加剂。

闸阀:闸阀是指关闭件(闸板)沿通道轴线的垂直方向移动的阀门，在管路上主要作为切断介质用，即全开或全关使用。一般，闸阀不可作为调节流量使用。它可以适用低温压也可以适用于高温高压，并可根据阀门的不同材质。但闸阀一般不用于输送泥浆等介质的管路中。低温阀门的种类、型式很多，现以低温截止阀为例，常见的故障可分为三类: 第一类:发生在阀顶上的故障。这种阀的阀顶(阀头)与阀杆是活动联结，以便在阀门关闭时两个密封面能"自动找正"。在长期使用后，有时因防退垫片损坏，使锁紧螺帽松脱，最后在开阀时使阀顶脱落。"中国社科院金融所货币理论和货币政策研究室主任彭兴韵这样表示。 显然，央行是希望通过此举为银行信贷打开阀门，以确保通过刺激消费和投资保持经济增速不大起大落。 不过，记者了解到，由于经济运行风险加大，企业信贷需求开始减弱，出于风险防范考虑，银行已经开始惜贷，贷款规模已不再是银行放贷的障碍。 "
