Chapter 5 . ceoi nanoparticles of average diameter about 30 nm were prepared by sol - gel method in lower temperature 另外，我们用自制的纳米氧化怖粉末制备了以醋酸纤维素为母体的稀土元素离子选择电极。
Zhuhai cellulose fibers co . , ltd held a ceremony meeting for the completion of the 2nd phase and the company ' s 20th anniversary on may 24th 珠海醋酸纤维有限公司24日举行大会,庆祝二期扩建工程圆满完成和公司成立十二周年。
As a excellent material for preparation of biomembrane , cellulose acetate ( ca ) is a fine carrier for the immobilization of cholesterol oxidase ( cod ) 醋酸纤维素( ca )作为一种优异的生物传感用薄膜制备材料，是胆固醇氧化酶( cod )优良的固体载体。
By gel filtration on sepharose cl - 6b and cellulose acetate pellicle electrophoresis test , hpa and hpb were respectively a single strait symmetry apex and the result of electrophoresis assume a single spectrum strip 经sepharosecl - 6b柱层析和醋酸纤维素薄膜电泳检验， hpa和hpb均为单一狭窄对称峰且电泳呈单一谱带。
Fluorescent brightening agent er is compound of chrysophenine , fluorescent brightening agent er is green yellow crystal , mainly used in the bleach of terylene , estron , polyamide fibre and washing powder 荧光增白剂er为二苯乙烯类化合物。荧光增白剂er的结晶为绿黄色结晶物，可用于涤纶、醋酸纤维、锦纶和洗衣粉的增白。
Concentrations , bore flow rate , dope solution temperature , coagulant bath temperature , 5 types of composite pu hollow fiber membranes were prepared . the recovery extent of different composition hollow fiber membrane pore size is different . the ability to recover of type 另外，在pu纺丝液中混入适量醋酸纤维素( ca ) ，也可有效改善pu溶液的可纺性，提高pu中空纤维膜的支撑强度和耐压强度，但压力响应性有所减弱。
In this paper are described the development history , present production situation and processing technology of acetate fiber of both at home and abroad , and introduced the main production now and its mechanical features of the fiber with some suggestions to develop china ' s acetate fiber industry put forward 摘要论述了醋酸纤维的发展史、国内外生产现状，以及醋酸纤维的生产技术，介绍了主要生产流程及纤维的物理机械性能，并对我国发展醋酸纤维工业提出了几点建议，包括建设规模、建设方式及设备国产化等问题。
After study on the technology of probe head of the optical fiber , a biosensor for determination of cholesterol which based on fluorescence quenching and adopted phase shift & phase lock technique to detect the change of light intensity was developed , in this biosensor , the cellulose acetate cod enzyme membrane was took as sensitivity basic dollar , ru ( phen ) 32 + was took as indicator of oxygen and furcated optical fiber as conduct carrier of light signal 通过对光纤探头组装技术的研究，以醋酸纤维素cod酶膜为敏感基元，钌( ) -邻菲咯啉为氧指示剂，分叉光纤为光信号传导载体，采用相移法和锁相放大技术设计了一种基于荧光猝灭原理的测定胆固醇用的生物传感装置。
The transport flux of k + and na + have been measured by those systems . in those systems the transport flux of k + and na + is higher than in supported liquid membrane systems , because of " jumping " transport model in fixed - site carrier membrane . in addition , polymer inclusion membranes ( cta - pim ) is tested 另一种是聚合物包含膜(三醋酸纤维素包含膜) ，并进行了促进传递试验，测定了在这两个体系中k ~ +和na ~ +的传递通量，比在支撑液膜体系中的高，这是由于在固定位置载体膜中载体浓度相当高，传递方式由扩散方式转变为跳跃传递方式。
