The traditional distinction based on the matrix attribute reduction algorithm analysis, for distinction in the matrix "repeat" Too many elements, these "duplicate" elements not only in solving attribute reduction in the process does not work, But also reduce the time efficiency by improving the shortcomings that distinction in the matrix structure in the process of using Proposition calculus in the absorption of the law removed the distinction between the functions of the non-functional "repeat"element, a property Reduction of improved algorithm RADM, improve the efficiency of the attribute reduction.

通过对传统的基于区分矩阵的属性约简算法进行分析后，针对区分矩阵中"重复"元素过多，同时这些"重复"元素非但在求解属性约简的过程中不起作用，而且还降低时间效率这一缺点进行了改进，即在构造区分矩阵的过程中，利用命题演算中的吸收律去掉了在区分函数中不起作用的"重复"元素，提出了一种属性约简的改进算法RADM，提高了属性约简效率。

The main collagens in skin are type I and III. In this research, total collagens were separated from rat skin by enzymatic digest and acetum methods. The collagens were denatured at 60℃ and digested with trypsin. Characteristic peptides typical for collagen type I and III were identified with high performance liquid chromatography/mass spectrometry.

哺乳动物皮肤真皮中胶原蛋白含量约为70%，主要为是I型、III型胶原蛋白，本实验利用稀酸溶解和酶法提取了大鼠皮肤中的总胶原蛋白，将胶原蛋白粗提品在60℃变性后用胰蛋白酶进行降解，液相色谱/质谱联用法分析了两种胶原蛋白的特征多肽，利用特征多肽比较了不同生长期大鼠皮肤中I型和III型胶原蛋白相对含量。

After acetylation of cellulose, the allomorph of CTA changed and the crystallinity decreased; however, amorphism is dominant in CDA obtained by hydrolysis from CTA and spinning resulted in the reduction of crystallinity in CDA.

纤维素乙酰化后形成CTA，其晶型发生变化，结晶度降低；而CTA水解后得到的CDA，无定形占明显优势，纺丝过程中的取向又会进一步降低CDA的结晶度。

The surface analysis results indicated by FTIR show that the RCO3Li obviously in the SEIof the carbon electrode with the introduction of a trace of anisole, after the first intercalation of Li＋ into the carbon electrode.

用FTIR对首次离子嵌入过程结束后的石墨电极表面SEI进行组成分析，发现加入苯甲醚后，电极表面SEI中的RCO3Li含量明显减少，但Li2CO3基本不变，并发现有新的产物CH3OLi生成。

The results showed that with treatment of the fixative solution added with antimonite,the free Ca2+ in pear different organs and tissues could be changed into antimonite calcium and precipitated in situ,which,after being stained,appeared as black particles under electronic microscope,whereas such particles could not be observed in the treatment without antimonite.

结果表明：在固定液中加焦锑酸钾处理进行制样，梨树不同器官或组织细胞中的自由态Caa2+，都能生成焦锑酸钙在原部位沉淀，经染色后在电子显微镜下呈现出黑色颗粒，而固定液中不加焦锑酸钾处理的则没有这种颗粒。

修改后的债务条款中涉及或有应收金额的，债权人不应当确认或有应收金额，不得将其计入重组后债权的账面价值。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

The corrosion rate, corrosive wear rate and polarization curves of aluminium brass and cupronickel alloy were determined in 3.5%NaCl and 3.5%NaCl+NH3(NH4+)solutions, the wear tracks of copper alloys were observed by SEM, the specific energy of the surface layer after corrosion was also measured by single pendulum scratching test.

本文通过测定HA177－2，BFe30－1－1在3.5％NaCl和3.5％NaCl＋NH3（NH4+）溶液中的腐蚀速率、腐蚀磨损率和电化学行为以及观测腐蚀磨损后铜合金的微观形貌，研究了腐蚀后样品的表层性能。

A study was conducted in the lab from April to June in 2000. Mnipponense were fed in different vitamin D3 diets for four weeks and in vitamin D2 and D3 (70001U/ I OOg) for three weeks. After four weeks, we measured the effect of vitamin D3 in diet on survival, moult, length and weight gain, and the effect of the content of Ca P in plasma, in curst, in muscle, and also measured the effect of vitamin D3 on RNA/DNA value, on protein content in plasma and AEC of muscle.

本研究于2000年4-6月间在实验室条件下，用不同含量的维生素D_3投喂日本沼虾(Macrobrachium，nipponense)，饲养4周；用7000IU/100g饵料的维生素D_2和维生素D_3投喂日本沼虾，饲养3周后，测定了饵料中添加维生素D_3 对其存活率、蜕皮率、体长和体重的增长率等形态指标的影响；同时测定了虾血、虾壳和虾肌肉中的钙含量、磷含量以及维生素D对RNA/DNA值、血中蛋白含量和肌肉中的能荷的影响；并从上述指标的测定中，比较了饵料中添加维生素D_2和维生素D_3对日本沼虾生长的影响。
