This paper set up a new method of SeC determination by differential pulse voltammetry at the / GC electrode.

依据SeC的还原峰电流与其浓度成线性递增关系，在充分探讨多种影响因素的基础上建立了／GC电极上微分脉沖伏安法测定SeC含量的新方法，其线性范围为5.0×10~(-8)～7.0×10~(-4) mol·L~(-1)，检出限为3×10~(-8) mol·L~(-1)。

It was found that the PCCG of the derivative could be 31.32% when 3 g starch and 3 g maleic acid were initiated by both 0.009 85 mol/L Fe2+ and 4.412 mol/L H2O2 and copolymerized at 60 ℃ for 5 h.

将中性的淀粉转化为含羧基的阴离子型聚电解质，是赋予淀粉功能性而提升其价值的一种有效途径。

MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.

铁浴中硅和钛的扩散是影响铁浴及熔渣与耐火材料作用的重要因素，耐火材料中添加的TiO〓和SiC受熔渣氧化和侵蚀，将被部分还原形成Si，Ti向铁浴中扩散，Si、Ti在铁浴中的扩散研究结果是： D〓=1.84×10〓exp（－5988.7/T） cm〓/S E〓=49766 J/mol D〓=7.76×10〓exp（－53225.5/T） cm〓/S E〓=442304 J/mol 铁浴式熔融还原熔体对粘土砖，高铝砖，镁砖的侵蚀速度很高，镁碳砖抗侵蚀能力比前几种耐火材料强，但不如铝碳砖；对不含碳耐火材料在熔体中的侵蚀是熔渣中FeO及其它氧化物与耐火材料组分的化学反应形成低熔点物熔蚀进入渣相，产生损毁。

The culture was treated with lutein of different concentrations 10^(-8mol/L、10^(-7)mol/L、10^(-6)mol/L, respectively. The culture cells were fixed and were stained for tartate-resistant acidic phosphatase after 7d. The formation of osteoclasts was quantified by counting the number of TRAP(superscript +) multinuclear cells. The percentage of bone resorbed surface, TRAP activity and the expression of receptor activator of NF-KB mRNA were analysed. The appearance of reduced mice osteoclasts was typical.
