Analytic personage points out , the share price of firm of not alexandrine city goes sign is possible because be restricted to make work current appear on the market in succession and appear differentiation , but current although a quantitative addition can arise to the market decrease maintain pressure , but the bounds of lift a ban made work 2007 current market prise photograph total to huge market market prise and do not calculate for the abundant financing on the market at present big 有分析人士指出,不同上市公司的股价走势有可能因限售流通股陆续上市而出现分化,可流通股数量的增加虽然会对市场产生减持压力,但2007年解禁的限售流通股的市值相对于庞大的市场总市值以及目前市场上充裕的资金来说并不算大。

According the key factors we find , we bring forward a new conception : multilevel suppressor and design a new high performance suppressor whose ion - exchange membrane has bigger areas and using three electrodes including one cathode ( anode ) and two anodes ( cathode ) , at the same time we fill the suppression compartment with one kind of ion exchange resin which has moderate exchange capacity . according to our experiment ' s results , we find the new type suppressor has quite high working current efficiency and suppressing capacity . in most cases , the suppressor ' s current efficiency is over 90 % ; the suppressor can transform the naoh ( concentration : 200mmol / l , flow rate : i . oml / min , conductance : over 10000 i - i s cm " ) to pure water ( conductance : 8 . 9 it s cm in chapter 3 , the high performance suppressor is applied in determination some trace - amounts ions in plating solution , sewage . in this chapter , we also have a research on the gradient ion chromatography 第二章首先以xyz - 1型电化学抑制柱为例,分析了电化学抑制柱的抑制过程得出影响抑制容量的主要因素主要是抑制柱的电流效率和离子交换膜的极限电流密度,因此采用中等交换能力的离子交换树脂作为抑制室的填料以提高电流效率,在通常情况下电流效率可达到90以上;在选用同种离子交换膜的前提下,可通过增加离子交换膜的有效面积达到提高极限电流的目的从而提高抑制柱的抑制容量,因此提出了多级抑制的概念并据此研制了共电极式高容量电化学抑制柱,该抑制柱最高可将流速为1 . 0ml / min ,浓度为200mmol / l电导率超过10000 s ? cm ~ ( - 1 )氢氧化钠溶液抑制为电导率低至8 . 9 s ? cm ~ ( - 1 )的纯水,并且具有稳定性高、分析结果准确等优点。
