The method comprises the steps of dipping and mixing the mipor asphaltic base globular active carbon prepared by the traditional method with an inorganic metal salt solution by a certain ration; heating under an inert atmosphere to 600 to 1200 DEG C at a temperature increasing rate of 1 to 20 DEG C/min for the secondary carbonization; using acid to wash off the remaining metal inside the carbonized material, so as to obtain the asphaltic base globular active carbon with a high mesoporous rate and narrow distribution of mesoporous spertures.

本发明提供了一种浸渍金属盐二次炭化制备中孔沥青基球形活性炭的方法，该方法是将传统方法制备得到的微孔沥青基球形活性炭按一定比例与无机金属盐溶液浸渍混合，然后在惰性气氛下以1～20℃/min的升温速率加热到600～1200℃下进行二次炭化，炭化料经酸洗除去内部残留的金属后，可制得中孔率较高、中孔孔径分布窄的沥青基球形活性炭。

For low molar ratios of Al/Zr, a hypsochromic shift of the initial catalyst absorption band, corresponding to the monomethylation of the catalyst, was observed. Further addition of AlEt2Cl was accompanied by a continuous bathochromic shift of the maximal wavelength corresponding to the formation of more dissociated ionic active species. Then, there would be a coordination of monomer to the ionic active species.

结果表明，无论是AlEt_2Cl还是MAO，少量的助催化剂首先使催化剂发生单烷基化反应，主催化剂金属中心的最大吸收峰波长发生蓝移，而当助催化剂量进一步增加时，金属中心的最大吸收峰波长红移，单烷基取代的催化剂被大量的助催化剂夺去电子成为缺电子的阳离子活性中心，以便烯烃单体的配位插入。

The aberrance itself is a kind of active research, which not only lengthways reviews the developing state of television art but also breadthwise compare the aberrant relationships between traditional arts and television arts, in order to find out aesthetic rules. The comparative method I adopt accord with the subject, appropriate revealing the active research characteristic.

电视研究是一种动态的研究，国家政策、经济发展、技术革新等因素都影响着电视的传播，电视艺术生态在呈动态发展，电视艺术美学也如此，&变异&问题本身就是一种动态的研究，它从纵向考察电视艺术的发展状态，同时还通过横向比较各传统艺术与电视艺术之间的变异关系，最终寻找出电视艺术的美学规律，而我所采用的比较的方法与影响研究是很符合这个选题的，这恰恰显示出了动态研究的特性。

在这篇教程中图的大小是1024×1024.STEP_SIZE是我们用来绘制地形的正方体的大小，减小步长，地形图就会变得更加平滑。有一点很重要，步长越小你的程序所做的工作就将越多，特别是在使用大的高度图时。HEIGHT_RATIO用来缩放地形的Y轴的值，较小的HEIGHT_RATIO可以用来绘制较平的山，较大的HEIGHT_RATIO用来绘制较高的山。在下面的代码中，你会看到变量bRender。如果bRender的值为真，我们就填充模式绘制多边形，如果它的值为假，那么我们就用线框模式绘制地形。

When the large vacuole in active cambial cells divided into smaller ones during the dormant phase, proteinaceous material that disappeared in active cambial cells refilled many of these small vacuoles.

活动期形成层细胞中的大液泡在进入休眠期后逐渐分成许多小液泡分散在细胞质中。随着液泡融合逐渐消失的深色蛋白类物质又重新充满了大部分液泡。

Chapter 2 Study on the preparation and application of a new electrical active-inactive switch molecular beaconWe developed a new electrical active-inactive switch molecular beacon and used carminic acid as signal molecule.

第二章：新型电化学活性-非活性转换分子信标的研制及其应用本章中，首先提出了一种基于电化学活性-非活性分子转换的新型分子信标。

Sn with the content of 0.004% in the lithosphere is almost in presence of cassiterite and little in presence of Sn-contained sulfide. Since 1980s, the anticancer active study on organic complex compounds has attracted considerable attentions, it becomes another hot issue after the study on Pt. When time up to the year 1989, the anticancer active measurement of more than 2000 kinds of Sn-contained complex compounds have been carried out by Cancer Academy, U.S, with the results showing half of these Sn-contained complex compounds posses antileucocythemia(P388) activity. Thereafter, Sn-contained complex compounds synthesized by hydrothermal reaction also become a hot issue people focus on.

Sn在地壳中的含量为0.004%，几乎都以锡石的形式存在，此外还有极少量的Sn的硫化物。20世纪80年代以来，人们对Sn有机配合物抗癌活性的研究产生了浓厚兴趣，成为继顺铂之后又一活跃的研究热点，到1989年，美国国家癌症研究所对2000多种Sn的配合物进行了抗癌活性测定，结果表明，50%的配合物具有抗P388白血病活性，故水热溶剂热合成锡的配合物也成为人们的研究热点。
