In 0.015 mol/L NaOH medium, AuCl4(superscript -)reacted with hexadecyl trimethyl ammonium bromide, forming water soluble CTMAB-AuCl4 complex that exhibited a weak absorption peak at 400 nm. In the presence of hydrazine, the reaction produced orange-red nanogold particle and exhibited a surface plasma resonance absorption peak at 520 nm.

在0.015mol/LNaOH介质中，氯金酸根离子AuCl(上标-下标 4与阳离子表面活性剂十六烷基三甲基溴化铵反应生成水溶性的CTMAB-AuCl4缔合物，在400nm处产生一个很弱的吸收峰，当有肼存在时，反应生成橙红色的金纳米粒子，在520nm处出现一个表面等离子体共振吸收峰，从而可实现废水中微量肼的分光光度测定。

The key technique to realize the system such as: the establishment of electronic map database ^ the search of the best pattu gobal position, map match and coordinate alternate etc, are discussed. The database of road information and main targets which is of much benefit to the realization of the system are built to manage the information of roads and main targets.

在研究电子地图数据库的建立方法时，为了克服现有电子地图的图幅接边在接边处会出现扭曲错位、难以管理地图信息、信息量少且难以更新等缺点，采用路网数据库和物标上题数据库来管理地图上的路网信息和主要物标信息。

Versicolor suited to grow and produce laccases at pH value 3.5-5.7, and unbuffered media were able to get good laccase productivity though buffered media could get higher laccase activity. Metal ions Cu(superscript 2+) and Mn(superscript 2+) in the culture could remarkably increase the activity of laccases. The optimal concentration of Cu(superscript 2+) was 0.008-0.08mmol/L, and the optimal concentration of Mn(superscript 2+) was about 0.01mmol/L, when the culture contained 0.1mmol/L 2,5-dimethoxyaniline.

结果发现该菌种适宜在pH值3.5~5.7环境下生长并合成漆酶，培养基中添加缓冲液可以获得更高的酶活，但不加则有较高的酶产率；铜和锰可以显著提高漆酶活力，当以0.1mmol/L 2，5-二甲基苯胺为诱导剂时，培养基中宜含0.008~0.08mmol/L Cu(上标 2+)，0.01mmol/L左右的Mn(上标 2+)。

In the reasonable drug molecular design,analyzing the conformations of the substrate without three-dimension structure and confirming its active conformation are very important to illustrate the spatial shape and active site of target enzyme. The active conformation of protoporphyrinogen IX substrate of protoporphyrinogen oxidase has been established using the Distance Comparisons DISCO method. In this paper, four different conformational molecules of Protogen IX and crystal molecule of diphenylethersAF are analyzed by comparing their geometry parameters. The results show the lower energy active conformation from the DISCO model is more reasonable.

在合理药物设计方法中，当靶标酶的三维结构未知时，对其底物进行构象分析，特别是确定其活性构象，对阐明靶标酶活性中心的空间形状和作用位点具有十分重要的意义我们曾利用距离比较法确定了原卟啉原氧化酶的底物—原卟啉原IX的活性构象，本文从构象分析的角度对4种不同构象的原卟啉原IX分子与二苯醚类分子的晶体学构象进行了几何参数的比较和分析，结果进一步证实了距离比较法所确定的活性构象更为可靠

The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。

Acting as an antenna molecule in the supramolecular system, Mg(superscript 2+)-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N, N-dimethylaniline.
