Open-shelf design method is put forward to frame the fault diagnosis expert system which could supervise locomotives with different types and different internal structures; moreover, the problem of various fault sources with complicated logic connections on electric locomotive is solved by the bidirectional fault diagnosis mechanism.

机车定位、设备故障等信息通过数据传输平台实时传输到监控中心，由故障诊断系统进行分析和诊断；而非实时信息直接存储在机车上并在离线状态下转储到监控中心数据库，作为机车状态变化趋势分析的依据，为机车的"状态修"提供参考和指导。

In this study, we performed sequential combined PI and DAPI staining and FISH with two different 45S rDNA clones on meiotic pachytene and mitotic metaphase chromosomes in tomato.

采用CPD染色对番茄减数分裂粗线期和有丝分裂中期染色体进行了显带分析，随后用两种不同的45S rDNA 克隆在相同的分裂相进行了荧光原位杂交定位分析。

A novel fault location algorithm for parallel transmission lines by one-terminal current is presented.

A novel three-dimensional localization method is proposed. Firstly, the tomato effective centric spots are obtained from the left multi-sensor fusion image and the right multi-sensor fusion image. Then, being looked as symmetries, image pairs other point to point correspondences are searched from two directions by pixel neighbor area correlation values by using the polar line restraint, the unique restraint and the disparity gradient restraint.

即从双目定位的几何模型出发，在双目匹配搜索中，提取多源传感融合图像的番茄凸壳有效形心点，采用极线约束、唯一性约束进行立体视觉图像的特征点及其邻域灰度相关的双向匹配，利用体视原理获取唯一被测目标的空间坐标。

Nephrometry Score consists ofadius,xophytic/endophytic properties of the tumor,earness of tumor deepest portion to the collecting system or sinus,nterior/posterior descriptor and theocation relative to the polar line.

结果：肾脏散色比浊法评分由下列部分组成：半径（以肿瘤最大直径作为衡量肿瘤大小的依据），肿瘤的外生/内生特性，与肿瘤最深处接近肾集合系统或肾窦的距离，对肿瘤前方/后方部位的描述以及与极线相关的定位。

Background and preprint lines are first removed;then seals are segmented ...

首先去除图像中的底纹和定位格线；然后通过迭代的方法选取阈值去除印章图像；最后采用基于连通区的区域增长算法提取字符图像，去除碎块。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
