Law of the propagation of errors caused by the inconsistency of the boundary scale similitude in river model experiment is presented in this paper. The fluctuation of scale transfers along the characteristic line,if the discharge and sediment at entrance and the water level at the tail gate drift. The fluctuation of scale propagates with the derived scale function due to topographic deviation. All errors will accumulate to the final measured data

目的比较Wnt4＇Bmp2,PRL在一胎早孕，二胎早孕，一胎胚胎停育，二胎胚胎停育蜕膜中的表达差异，探讨它们与早孕的关系及一胎分娩史与胚胎停育的关系。方法选取一胎，二胎胚胎停育患者及正常一胎，二胎早孕自愿流产女性各30例，用免疫组化法检测蜕膜中Wnt4，Bmp2，PRL的表达。结果Wht4，Bmp2，PRL在正常早孕蜕膜中的表达显著强于胚胎停育蜕膜（P〈0．01），Wnt4，Bmp2，PRL在一胎和二胎胚胎停育蜕膜中的表达差异无统计学意义（P〉0．05）。结论早孕期蜕膜中Wnt4，Bmp2的正常表达对子宫内膜蜕膜化及维持妊娠有重要意义，单纯一胎分娩史与胚胎停育无相关性。

本文通过估算2011-2020年我国成品油需求,进而估计原油总需求及由此可能产生的能源缺口。研究结果表明,我国汽车和交通运输业对成品油的需求量较大、增长较快。如果基于能源安全考虑把原油对外依存度控制在60%-65%之间,就会产生明显的原油和成品油缺口。弥补原油缺口的途径主要有液态生物质燃料补充、发展混合能源和新能源汽车、节能降耗等几个方面。其中最快捷有效的途径是采用燃料乙醇与生物柴油补充成品油的不足,因此要加强对液态生物质燃料产业的扶持和激励,促进液态生物质燃料的发展。

随着互联网技术的发展,P2P网络借贷的用户与数据量与日俱增。识别出异常的借款标的,促进平台的健康发展一直是社会关注的热点与焦点。针对这一问题,本文提出了"多层次分类"方法,以lending club发布的交易数据为研究对象,分层次进行数据分析。在第一层次,首先采用基于密度的DBSCAN聚类算法,排除大量正常用户,减弱数据中正负两类分布不均衡的缺陷;在第二层次,采用一般分类算法进行分类,最终识别出平台的异常借款标的。数值实验发现,将"多层次分类"方法应用在P2P网络借贷中,相比于其他方法,能在保证分类器整体性能的情况下,更有效地识别出异常还款的借款标的。
