Summer high temperature season, especially in highly alkaline (pH 8 ~ 9.5) and high-nitrogen low-phosphorus breeding water body, often there will be kind of the large population of blue-green algae in the water to form a layer of green, cloud porphyritic, ribbon objects , commonly known as "water-hua."

盛夏高温季节，尤其是强碱性(pH 8～9.5)和高氮低磷的养殖水体，往往会出现蓝绿藻类的大量繁殖，在水面形成一层绿色、云斑状、带状的物体，俗称&水华&。

In this paper, the preparations, analytical methods, physical characteristics of ferrates and the application of ferrates in the fields of synthesis of organic compounds, treatment of waste water and the usage as cathode material in alkaline batteries are summarized. The electrochemical preparation of sodium ferrate is described and the relationships between the main parameters in the process are deeply investigated. One method of in-situ electrosynthesizing potassium ferrate of high purity with both high efficiency and low energy consumption is invented. The cyclic voltammogram and feature characterization of iron anode in alkaline solutions is studied. One preparation method of ex-situ electrosynthesizing tripotassium sodium ferrate of high purity is created.

Methods by using a broad pH range column(Gemini NX C18,4.6mm×150mm,5μm),basic mobile phase which was[H_2O-ammonia-glacial acetic acid] (96:3.6:0.4)-methanol,the related substances in etimicinsulfate were separated and detected by electrospray ionization and positive ion monitoring,the ESI ion source condition was following: temperature is 350℃,nebulizing pressure is 50 psi,dry gas flow is 10 L /min.some related substances in etimicinsulfate were identified by comparing the retention time in chromatography,~+ spectrum and MS~2 spectrum with reference substances\',the others which haven\'t reference substances were identified or speculated by analyzing their MS~2 fragmentation with the help of a rule summarized from the MS~2 fragmentation of gentamicin C1a,micronomicin and etimicin.Results nineteen related substances in etimicinsulfate were separated and detected.

方法利用宽pH范围的Gemini NX C18(4.6mm×150mm，5μm)色谱柱，在碱性条件下，以[水-氨水-冰醋酸(96：3.6：0.4)]-甲醇(70：30)为流动相，直接分离各组分；并用HPLC-ESI-MS~2检测样品中各组分，质谱条件：ESI离子源，离子源温度350□，雾化室压力50 psi，干燥气流速10 L/min，正离子检测方式；对有对照品的有关物质采用比对有关物质与对照品的色谱保留时间、准分子离子的质荷比及二级质谱方法进行鉴定，无对照品的有关物质，则是先通过解析庆大霉素Cla、小诺霉素、依替米星的二级质谱，对该类化合物的二级质谱裂解规律进行归纳，并以此推测未知新化合物进行结构，再用推测的结构对二级质谱进行解析，如所有的碎片离子均合理解释，表明推测合理。

Therefore, we developed a call "NaMi-863" of thermoplastic pipe (the franchise has been granted, state: ZL200620009651.8) It is mainly iron pipes do not solve the basic acid-fast, short life-corrosion flaws , As long as 50 years of its life, but also a metal pipe to solve the water pollution, never to corrosion, but also solved the general strength of small plastic pipe, the flange-shedding and other shortcomings, and its strength has greatly exceeded its design Requirements, specifications and the same iron pipes, iron pipes is the alternative.

因此我们研制出一种叫&NaMi-863&的热塑钢管(已被国家授予专利权号：ZL200620009651.8)它主要解决了铁管不抗酸碱性，易腐蚀寿命短的缺点，它的寿命长达五十年，同时也解决了金属管子对水的污染。它永不腐蚀，也解决了普通塑料管强度小、法兰盘易脱落等缺点，它的强度大大超过了其设计要求，规格与铁管相同，是铁管的替代品。

That is the reason we drink Alkaline anti-oxidant Water!

那就需要饮用我们的碱性抗氧化水！

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
