The methods determing the groups in the modified starch have been developed, that is acidimetry for the basicity of acidified starch, complexing titration for the substitution degree of carboxymethyl starch, and heat paste titration and carbonyl process respectively for the carboxyl and nitrogen of oxidized starch.

建立了以酸碱滴定测定酸化淀粉的碱量、络合滴定法测定羧甲基淀粉的取代度、热糊滴定和羟胺法测定氧化淀粉中羧基及羰基、消化定氮测定阳离子淀粉等几种变性淀粉的基团分析方法。

Notch and groove were produced on fiber's surface by plasma's pHysical bump and corrasion, meanwhile oxygenic or nitrogenic radicals were also grafted on the surface. Through hydrolyzation, acetate fiber's surface will be denuded by cellulase enzyme. Surface of the fiber will be granulated and specific surface area will be enlarged by plasma and enzyme treatment, therefore obviously improve fiber's surface performance.

等离子体对纤维的物理撞击和表面刻蚀使纤维表面产生凹坑和沟槽，同时可在纤维材料表面引入含氧或含氮基团；而纤维素酶对纤维素的水解作用，促使纤维表面被剥蚀；等离子体与生物酶处理都能使纤维表面粗糙化，比表面积增加，使纤维的表面性能得到明显改善。

Based on the correlation matrix of the data sets, a two factor model was extracted to interpret the aquatic chemical characteristics of the lake.

主因子分析的结果表明，由氮营养化引起的污染是控制山丹湖富营养化水化学特征的主要因子

3 Recently, we reported an efficient tin-free version of this reaction involving thiophenol for the preparation of cyclopentane derivatives through a 1,5-hydrogen transfer/cyclization sequence [Eq.(1); AIBN=azobisisobutyronitrile].

最近，我们报道了高效的、不使用锡试剂而使用苯硫酚的反应，这个反应是通过1，5-氢转移/环化步骤制备环戊烷衍生物的[化学反应式(1)；AIBN=偶氮二异丁腈][4]。

Methods: We divide the rats into 5 groups in random, with Morris method, detect the change of some active oxygen radicals such as super-oxide demitasse, Nitric Oxide Synthase, malondialdehyde etc. Also, we detect the change of cholinesterase, Monoamine Oxidize; using HE,PAS staining, immuno-histochemical technique, detect hippocampus CA1 cerebral pathology slices optical density value of NOS, CHE and lipofuscin of neural cell; detecting apoptosis rate and the expression of P53 , which are neuronal apoptosis related genes.

The changes of amino-N were basically identical both in saccharificated and liquidized WWWSIs They reached the lowest point at 16h, then rose slightly.

在糖化和液化两种废水中的氨态氮变化趋势基本一致，均在16h达到最低水平后有少量的回升。

Second, we discuss two materials which are cinnamoyl chloride and azobenzene. The cinnamoyl chloride can induce the photo-dimerization reaction under linear-polarized UV light. Similarly, azobenzene can induce the cis-trans photoisomerization under UV light.

第二部分采用光诱导配向的方式，将偶氮苯与PI结合，再利用偏极化紫外光曝光使其产生顺-反异构化反应，再用polarized-ATR-FTIR研究其三度空间之分子排列，做为未来显示器配向膜的参考。

Plasma concentrations of nitric oxide, atracurium, and 1-acid glycoprotein were measured and acetylcholine receptor numbers were quantified.

The novel molecular topological index was recommendedrelating to such atomic properties as electronegativity,electron number of valence shell,number of bonding electrons,the main quantum number of valence shell and bond length.

采用该拓扑指数对饱和烷烃、烷基苯、烷氧氯硅烷、卤代苯、含氮杂环化合物、碱金属卤化物及卤化锡的性质/活性进行了相关关系的研究。

Ocular crosssections were prepared for staining of HE and eyeball slicing parallel TUNEL staining. To observe the cell morphology of 4 groups RGCL.

眼球切片并行TUNEL染色和HE染色，观察4组RGCL的细胞形态，免疫组化染色观察诱生型一氧化氮合酶的表达。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
