  1. Ion suppression chromatography, isc

    離子抑制色譜法
  2. Ion chromatography with suppression conductometric detection was applied to the determination of anions and cations in sea water

    摘要採用離子交換抑制電導法測定海水中陰、陽離子。
  3. 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型電化學抑制柱為例，分析了電化學抑制柱的抑制過程得出影響抑制容量的主要因素主要是抑制柱的電流效率和離子交換膜的極限電流密度，因此採用中等交換能力的離子交換樹脂作為抑制室的填料以提高電流效率，在通常情況下電流效率可達到90以上；在選用同種離子交換膜的前提下，可通過增加離子交換膜的有效面積達到提高極限電流的目的從而提高抑制柱的抑制容量，因此提出了多級抑制的概念並據此研製了共電極式高容量電化學抑制柱，該抑制柱最高可將流速為1 . 0ml / min ，濃度為200mmol / l電導率超過10000 s ? cm ~ （ - 1 ）氫氧化鈉溶液抑制為電導率低至8 . 9 s ? cm ~ （ - 1 ）的純水，並且具有穩定性高、分析結果準確等優點。
  4. Therefore in terms of relativistic heavy ion collisions it is possible for quark and gluon to deconfine in wider range and form quark - gluon plasma. the initial consideration of j / ? suppression in deconfined medium is based on color screening

    相對論性重離子碰撞實驗是用高能加速器把重離子加速到很高能量實現重離子與重離子的碰撞，從而有可能在一個相對較大的范圍解除夸克、膠子的禁閉，形成qgp 。
  5. Ion suppression chromatography

    離子抑制色譜法
  6. The newly identified gene, nyd - sp27 has structural similarity to an isoform of phospholipase c. nyd - sp27 was expressed endogenously in human pancreatic - duct cells and upregulated in cystic fibrosis. researchers has proved that suppression of the gene resulted in augmentation of phospholipase - c - coupled calcium - ion release and protein kinase c activity, improvement in the amount of mutated cftr reaching the plasma membrane, and thus restoration of pancreatic anion secretion

    Nyd - sp27內源性表達在人體的胰腺導管上皮細胞，並在囊性纖維化時表達增高，顯示該基因可能與病變有關。研究人員發現通過抑制該基因在人體囊性纖維化胰腺導管細胞中的表達，可以糾正缺陷的胰腺陰離子分泌。
