How well do I remember her parlour half filled with the organ which her husband had built, and scented with a withered apple or two from the pyrus japonica that grew outside the house; the picture of the prize ox over the chimney-piece, which Mr Pontifex himself had painted; the transparency of the man coming to show light to a coach upon a snowy night, also by Mr Pontifex; the little old man and little old woman who told the weather; the china shepherd and shepherdess; the jars of feathery flowering grasses with a peacock's feather or two among them to set them off, and the china bowls full of dead rose leaves dried with bay salt.

To make special sets, the same principle as for standard domino sets is used: each bone has two ends; on each end there are several dots; a set contains bones with all possible combinations of ends; there are no two equal bones (there is no distinction with respect to left or right ends, so, for example, bones 2-5 and 5-2 are considered equal).

作出特别规定，同样的原则作为标准是：每一个多米诺骨牌集骨有两个顶点；在有几个点(从0加速到给定的数字)；一组包含骨与所有可能的组合；没有两个相等的骨头无区别就向左或向右结束，所以，举个例子，骨头2 - 5和5 - 2被认为是平等的。

According to structural characteristics of floating slab tracks, a track segment element was taken between two adjacent fasteners. For each element, rails were regarded as Euler beams supported by discrete viscoelastic supports. The fasteners and rubber supports were replaced by a linear spring and damp. So the vibration model of the floating slab track was established. In constructing vibration model of a metro train, each car of the metro train with two suspensions was modeled as a multi-rigid body system, in which rigid bodies were connected with each other by a linear spring and damp. Combining the potential energy of vertical vibration of the track with that of the metro train, the total potential energy of vertical vibration of the train and track was obtained. And then, the matrix equation of vertical vibration of the system was established using the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-position" rule for formulating system matrices. The vibration responses of the system can be obtained by solving the matrix equation with the direct time integration such as Wilson-θ method.

摘 要：针对浮置板式轨道结构特点，取相邻2个扣件之间的轨道为1个轨段单元，钢轨视为连续弹性点支承Euler梁，浮置板视为弹性薄板，扣件系统及橡胶支座均模拟为线性弹簧及粘滞阻尼器，建立浮置板式轨道振动模型；将城轨列车中的车辆均离散为多刚体系统，各刚体之间通过线性弹簧及粘滞阻尼器相连，建立列车振动模型；将浮置板式轨道及列车振动势能叠加，得到系统竖向振动总势能；基于弹性系统动力学总势能不变值原理及形成系统矩阵的"对号入座"法则，建立此系统竖向振动矩阵方程；采用Wilson-θ逐步积分法求解此矩阵方程，得出此系统竖向振动响应。

The basic theories of mathematical morphology for binary image are stated, and the most simple structure elements of morphologic transformation for binary images are proposed and proved. The geodetic morphologic transformation models are also developed. For the purpose of improving the speed of transformation in computer, the"set symmetric difference"is introduced to adapt each model. Some new morphologic filtering models and quantitative evaluating model of filtering effects in image processing are proposed, under the applied condition. The morphologic thinning methods are studied, and two new morphologic thinning models are developed. On the basis of analyzing the characteristics of mining maps, the image vectorizing tactics and a series of algorithms are proposed, including dynamic adaptive image thresholding using two thresholds, graphic and text separation, noise removal, and multi elements extracting models with mathematical morphology. Accuracy preserving compressed vectorizing model for image vectorization is put forward to generate vector data in multi layer.
