In 1876, Robert Koch a German doctor and bacteriologist found that anthrax, a disease occurring in warm-blooded animals grew from only viable rods or spores of bacillus anthracis.

1876年，德国微生物学家Robert Koch由牛眼中发现炭疽菌的纯种培养法，并获得1905年的诺贝尔医学奖，使得日后的法国生物学家巴斯德得以发现疫苗的制作方式，人类从此免於疫病的烦恼。

By discussing the position hypothesis of fractional-dimension derivative about general function and the formula form the hypothesis of fractional-dimension derivative about power function, the concrete equation formulas of fractional-dimension derivative, differential and integral are described distinctly further, and the difference between the fractional-dimension derivative and the fractional-order derivative are given too. Subsequently, the concrete forms of measure calculation equations of self-similar fractal obtaining by based on the definition of form in fractional-dimension calculus about general fractal measure are discussed again, and the differences with Hausdorff measure method or the covering method at present are given. By applying the measure calculation equations, the measure of self-similar fractals which include middle-third Cantor set, Koch curve, Sierpinski gasket and orthogonal cross star are calculated and analyzed.

Methods :we used step increased load running training way to establish a aerobic and fatigue training model of rat, then applied respectively HE staining、Masson staining and immunohistochemisty SABC method to observe the change of AVN tissue structure and Cx43 and Cx45 expression of Koch triangle; and used electron microscope to observe the ultramicroscopic structure change of AVN parenchymal cell of Koch triangle.

采用跑台训练方式，建立大鼠有氧训练和疲劳训练模型，分别采用普通HE染、Masson染色及免疫组化SABC法，观察Koch三角区AVN组织结构变化及其Cx43和Cx45的表达；采用电镜观察Koch三角区AVN实质细胞的超微结构变化。

Koch.m the program draws files Helge von Koch snowflake, a fractal graphics, the realization of fractal geometry in a basic graphics, the debris is not an integer number of graphics.

详细说明：文件 Koch.m 该程序画出Helge von Koch 雪花，一个不规则碎片图形，实现分形几何中的一个基本图形，该碎片图形的为数不是整数。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
