Nowadays, it has been extensively accepted that the double exchange interaction plays a key role in perovskite manganites. Therefore, in this thesis the effect of the double exchange is studied by doping on Mn sites.

目前，普遍认为双交换作用对钙钛矿结构氧化物中存在的CMR效应起到非常重要的作用，因而本论文通过对Mn位的元素替代来考察掺杂后对双交换作用的影响。

The calculation is based on the actual length of the first line if this line has a full or partial double. Not included are double tracks, station sidings, tracks under the charge of stations, branch lines, special-purpose lines and non-payable connecting lines.

凡是全线或部分建成双线及以上的线路，以第一线的实际长度计算；复线、站线、段管线、岔线和特别用途线以及不计算运费的联络线都不计算营业里程。

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.
