The nickelous chloride both may use in to galvanize, and is prepares the galvanization chemical thionamic acid nickel the important raw material, lead is affects the electronickelling quality a important attribute, in the present industry 331 ion exchange resin deleading effect still could not arrive in the electronickelling the lead content standard, used pocket weak basicity resin XSC312 after the screening experiment determination to take from the nickelous chloride solution intermediate ion exchange except the micro lead resin, inspected the material fluid pH value, the contact duration in the ionic exchange column to the ionic exchange adsorption lead influence, has determined the resin adsorption capacity and inspected the resin analysis performance.

氯化镍既可用于电镀，又是制备电镀化学品氨基磺酸镍的重要原料，其中的铅是影响电镀镍质量的一个重要因素，现行工业中的331离子交换树脂除铅效果尚不能到电镀镍中铅含量标准，经过筛选试验确定采用大孔弱碱性树脂XSC312作为从氯化镍溶液中离子交换除微量铅树脂，在离子交换柱中考察了料液pH值、接触时间对离子交换吸附铅的影响，测出了树脂的吸附容量并考察了树脂的解析性能。

Through on-site observation, interviews, analysis of their parents and teachers to exchange dynamic behaviour drawed: The purpose of parents' meeting with children is too simple and lack of opportunity for the exchange of awareness; Most of them are so impatient that miss the opportunities of communicating with teachers. Facing more than 30 parents at the same time, teacher can alleviate pressure on exchange through cooperation with other teachers. In exchange status, teachers played a dominant role to give professional guidances, major parents will listen to the views of teachers, less be active to express their own views. Whether parents or teachers, the use of communication strategies can effectively enhance communication effectiveness.

通过现场观察、访谈，分析接送交流中家长和教师的动态行为得出：家长接孩子目的单一，较心切，缺乏等待交流时机的意识；教师需要合作分工缓解交流压力；在交流地位上，教师发挥专业指导作用处于主导地位，家长以听取教师意见为主，有陈述己见趋势；但无论是家长还是教师，交流策略的使用能有效地加强交流的有效性。

Shanghai exchange resin resin plant special enterprises in China are domestic professional research and development, application, management services, OEM resin enterprise as a whole.major enterprises in China have Styrene, acrylic acid series, strong acid, strong base, weak acid, weak base, chelating , inert ion exchange resins, special enterprises in China for many years with several well-known enterprises to explore the application of ion exchange resins, the key products used in softened water, desalination water treatment-exchange resins; condensate treatment resin; food, fermentation industry Decoloration, dedicated Absorption resin, petroleum, chemical, medical, chelate resin and catalyst series dedicated resin as well as ancillary treatment, such as a series of packing products, such as a variety of grades.

If selects in the research the base period is different, for example some people take the high bloating year as the base periods, some people take the low bloating year as the base periods, has take the nominal exchange rate big adjustment before as the base period, has depreciates after year take the standard currency as the base period, finally obtains the balanced actual exchange rate difference extremely is big, causes one person to have a judgment exchange rate detuning standard, has like this lost the balanced exchange rate research significance.

如果在研究中选取的基期不同，例如有人以高通胀年为基期，有人以低通胀年为基期，有以名义汇率大调整前为基期，有以本币贬值后的年份为基期，最后得到的均衡实际汇率差异就非常大，导致一人有一个判断汇率失调的标准，这样就失去了均衡汇率研究的意义。

Because our country is the exchange control country, our company pays foreign currency of USD9762.50 to your company through Industrial and Commercial Bank of China, need going to Administration of Foreign Exchange Control to cancel after verification according to the customs declaration of the goods at the Chinese customs, if did not go to Administration of Foreign Exchange Control to cancel after verification, this sum of foreign currency that our company pays to your company will be determined as the true-false method expenditure foreign currency, our company will be listed in the blacklist by Administration of Foreign Exchange Control, thus freeze all foreign currency operation of our company.
