针对致密砂岩储层的孔隙度、渗透率极低,物性及孔隙结构定量表征困难等问题,将图像处理技术引入铸体薄片分析中,通过改进Sigma滤波有效去除图像噪声,得到高分辨率和信噪比的铸体薄片图像.应用多维阈值分割和形态学滤波方法实现孔隙提取和二值化.在孔隙提取的基础上,应用计点统计技术和拓扑学方法实现了孔隙微观参数如平均孔隙半径、圆度、孔隙纵横比的定量计算,突破了过去对铸体薄片以定性和半定量为主的局限性,有效地挖掘了铸体薄片的孔隙结构内涵信息.将结果与压汞毛管压力参数对比可知,基于铸体薄片的孔隙微观参数与压汞孔隙微观参数在表征孔隙结构上具有一致性.与压汞毛管压力、岩心核磁共振等实验相比,铸体薄片对样品要求简单,测试速度快,且由于高温高压注入技术能将染色树脂极大程度地注入孔隙空间,在致密砂岩储层孔隙结构定量表征中具有无可比拟的优越性.

Some tube hydroforming process tests and further research work were conducted to manufacture hollow guide vane liners( made of super alloy GH3030).The relative thickness( t0/ OD) of the tubular blank is approximately 0. 01,and the maximum expansion ratio( Dmax/ OD) of the needed part is more than 40%,and the length to diameter ratio of the expansion regionis more than 3. 0. It is very hard to manufacture this kind of ultra-thin-wall,curved axis and large expansion ratio tubular part without fracture and wrinkles. The success of the process is highly dependent on useful wrinkles with appropriate internal pressure and axial feeding. A simplified finite element model and a theoretical model are used for detecting the deformation behavior and forming laws. Further study results demonstrate that the useful wrinkles do not appear at the same time and middle-wrinkles need bigger axial force than tube-end-wrinkles and feeding-wrinkles. The wrinkles can transfer bigger axial force after its wave peak has come into contact with the die inner surface. The thickness thinning rate of the element at the peak is bigger than that at the trough. With the increase of the axial and hoop stress ratio,the critical buckling stress also increases. Microstructure examination results show that the grain size in the maximum thinning zone has been stretched and refined after the large deformation and annealing *** process is feasible and the finished part is qualified.

In order to clarify the correlations between the free spindle pruning mode and various factors in Fuji apple,the growth data of the free spindle-shaped short branch Fuji apple Tianhong No. 2 and the free spindle-shaped long branch Fuji apple Changfu No. 2 in the Apple Demonstration Park of Xingtang County,Hebei Province were investigated. Using SPSS statistical software,the correlations between the stem tapering grade and various growth traits were analyzed. The results showed that in Tianhong No. 2,the stem tapering grade was negatively correlated with various growth traits of the central shaft,and the correlation coefficients between the stem tapering grade and the central shaft total thickness,the central shaft average thickness,the central shaft total length and the central shaft average length were-0. 228,-0. 033,-0. 411 and-0. 430,respectively; and in Changfu No. 2,the stem tapering grade was positively correlated with various growth traits of the central shaft,and the correlation coefficients between the stem tapering grade and the central shaft total thickness,the central shaft average thickness,the central shaft total length and the central shaft average length were 0. 475,0. 181,0. 120 and 0. 258,respectively. This paper can provide a scientific basis for guiding the construction of free spindle pruning mode in densely planted dwarf apple trees.

欧洲会计协调是指欧盟为了协调各成员国的会计活动,通过制定和颁布一系列指令,对各国会计准则上的差异设定限度,以增加欧盟内各国会计实务和财务信息的统一性和可比性。从集体行动逻辑理论的观点看,这可视为一种两个以上的个人(此处指政府)形成的一项以会计准则为标的的特殊契约交易的集体行动。本文将对欧洲会计协调的分析与思考纳入集体行动逻辑的理论框架中,在解释其现已取得成就的基础上,重点对欧洲会计协调中出现的障碍加以深入的研究和剖析,并展望其未来的发展之路。

In order to clarify the correlation between short-shoot Fuji apple tree structure and different factors under different trimming and pruning modes,we investigate the trunk taperingness of free-spindle short-shoot Fuji and slender-spindle short-shoot Fuji,respectively,as well as the total thickness,average thickness,total length and average length of small main branches in the standard demonstration apple garden in Xingtang County of Hebei Province. By SPSS analysis,we study the correlation between trunk taperingness of trees with different shapes and the growth indices of their small main branches. The results show that the trunk taperingness of free-spindle short-shoot Fuji apple is negatively correlated with the total thickness,average thickness,total length and average length of small main branches,but the correlation is not significant; the trunk taperingness of slender-spindle short-shoot Fuji apple is negatively correlated with the total thickness but positively correlated with other factors,and the correlation with average length reaches a significant level. The results of this study can provide a scientific basis for guiding the high-density dwarf rootstock short-shoot Fuji apple tree trimming technology.
