One, the exterior reason of get into trouble of railroad construction company those who build product value is unreasonable be since one of main reasons that cause depression of benefit of railroad construction company are long-term, building product fixes a price not the price system of discomfit economy, the quota that the cost that builds a product still sets by the country reachs standard extraction cost to decide.

一、铁路施工企业陷入困境的外部原因建筑产品价格的不合理是导致铁路施工企业效益不景气的主要原因之一长期以来，建筑产品定价未打破计划经济的价格体制，建筑产品的造价仍由国家规定的定额及取费标准来决定。

The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

Point clouds are discrete data points without the topology relationship between them. So, to facilitate and expedite the extraction of contour points for the late NPR style, firstly we should simplify the point cloud data. In other words, non-contour points should be eliminated but their contour points and feature points should be retained .

点云数据本身是无拓扑关系的离散数据点集，所以，为了方便和加速后期非真实感绘制风格化所需轮廓点的提取，首先对点云数据进行了"粗略"地简化处理，即剔除点云数据中非轮廓点保留了其轮廓点和特征点；然后应用判定准则提取出所表示物体的轮廓点并对其进行"归并"形成便于NPR风格化处理的特征轮廓线；最后再对得到的轮廓线进行NPR风格化效果"加密"处理。

Due to discretization error of image points and inevitable location shifts embedded in feature extraction processes, the parameters of a line determined by two feature points must possess some uncertainties.

由于图像特征点的离散误差和特征点提取过程中的位移现象，使得由二图像点所确定的直线的参数随之产生某种不确定性。
