Through investigation on the Eh values of cinnamon soil,sierozem,brown desert soil in situ with new electrochemical methods and summarization of the same results of laterite,red soil and yellow brown soil,a horizontal zonal variation of oxidation-reduction characteristics in semi-humid,semiarid and arid areas from south China to north China is revealed.

用新的电化学方法原位考察了褐土、灰钙土、棕漠土、黑土、风沙土、灌淤土、盐土、碱土、亚高山草甸土、灰褐土、水稻土和旱地土壤的氧化还原状况。综合已有原位测定结果，地带性土壤的电位由南向北的空间分异与其水平地带谱相应；亚高山草甸土和灰褐土的氧化还原状况随山体高度和植物群落而呈垂直分异趋势。

The content included (1) characterizing macropres shapes;(2) obtaining the index to charaterizing soil macropore quantificationally through digitalizing and analysising the photo of soil section;(3) comparing the shapes of macropores among soils, which reasons were discussed;(4) studying the influence of the zonal diversity, soil depth and land utilization on macropore characeristics;(5) estimating the space variability of macropore in the microscale using spore variability index;(6) analysising the connectivity and sinuosity of macropore using preferential flow breakthrough curve;(7) discussing the feasibility of indicating the preferential flow degree using macroporosity and macropore perimeter.

系统划分了大孔隙类型；描述了大孔隙形态；通过对土壤切片图像数字化处理和分析，获得了描述大孔隙特征的两个基本指标：大孔隙度和周长，并对大孔隙进行了定量化地描述；比较了各土类之间大孔隙的形态差异，从土壤发生学的角度对其原因进行了分析；研究了地带性差异、土壤层次和土地利用方式对大孔隙特征的影响；阐明了小尺度范围大孔隙的空间分布特征；结合Br〓标记优先水流穿透曲线分析了大孔隙的连通性和弯曲性，探讨大孔隙形态指标评价大孔隙优先水流作用强弱的可行性。

The distributions of subaerial algae in Jilin's terrestrial ecosystem are different with the difference of zonal vegetations. The distinction is embodied in the species quatity and subaerial algae's thallus shape.

由于各种因素的综合影响，东北森林-草原样带中的各地带性植被内的亚气生藻类在分布上有较大差别，这种差别主要体现在种类数量和藻类的原植体形态上。

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。
