The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j . r . l . allen ; gets a group of parameters including the reservoir thickness , porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters , that is x h , kxh and h / h , and accounts the favorable region . on the base of above - mentioned studies , the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field Allen )等人提出的统计方法，用垂向上砂体密度的界限来推测砂体侧向连通情况；根据每口井的测井解释资料，利用克里金插值法对外间进行插值，得到了一组反映储层特征在平面上变化的参数，包括储层厚度分布、孔隙度以及渗透率，并且成图；利用变差函数法，通过球状函数模拟，确定储层优势渗透率方向：根据流动单元法，以储能系数、容积系数以及净毛厚度比三个参数为依据，通过聚类分析方法进行流动单元划分，并且按照参数特征将其分为五类，统计各砂层有利流动单元区块。
A great deal of research is being devoted to the understanding of systems , biomimetic and otherwise , that self - assemble into organized structures . liquid crystals represent one of the best known classes of self - organizing materials , exhibiting properties that range from surfactants that can form micelles , monolayers , and membranes , to the rodlike molecules used in liquid crystal displays , to the recently discovered disc - like liquid crystals 卟啉液晶分子是一种共轭大环化合物，其周边有十二个活性部位可与不同的柔性侧链相连接，且分子的长径比与直径厚度比等均可以调整，因此，可以通过分子设计在卟啉的周边引入柔性侧链合成出新型具有期望性质的卟啉液晶材料。
The low re k - model in software phoenics3 . 3 were applied to simulating indoor air temperature field in this two kinds of heating room contrastively . it shown that temperature gradient at human altitude in floor heating room is lower 3 ~ 4 c than radiator heating room , temperature adjacent out wall and out window near by radiator is higher 6 ~ 7 c than mean indoor temperature , temperature different of room top with mean indoor temperature in top floor radiator heating room is higher 1 ~ 2 c and thickness is 0 . 3 ~ 0 . 5m thicker than floor heating room 结果显示：在人员活动高度区域内，低温地板辐射供暖房间的室内空气竖向温度梯度比散热器供暖房间小3 4 ；在散热器供暖房间内，靠近散热器的外墙附近和散热器上部的外窗附近空气温度高于室内平均空气温度6 7 ；在顶层房间，散热器供暖房间顶部温度与房间平均温度之差比低温地板辐射供暖房间高1 2 ，高温区厚度比低温地板辐射供暖大0 . 3 0 . 5m 。
For confirming the results , a full - size model ( dj / dj = 0 . 6 , t / t = 1 . 5 ) was analyzed by means of strain gauge test . the reliability of finite element analysis was proved because the results basically accorded with that of the test . secondly , in this paper , in order to carry out a fair assessment of the reinforcement design on spherical shell with transnormal nozzle , a comparison of reinforcement method was done between jb4732 - 1995 steel pressure vessels ? esign by analysis appendix a4 and hg20582 - 1998 specification for stress calculation of steel chemical vessels 为了验证ansys分析结果的可靠性，对其中一组参数下(开孔率0 . 6 、厚度比1 . 5 )的模型容器，采用电测法进行了应力测试，并将得到的实验结果与有限元结果进行了比较，二者在应力分布状况和大小上均基本吻合，证明此种结构运用ansys进行分析，其结果是完全可靠的。
Therefore , the solution of the problem can be reduced to a seri es of algebraic equations and solved numerically by truncating the finite terms of the infinite algebraic equations . finally , given two kinds of incident wave and different dimensionless parameters , numerical examples are provided to show the influence of wave number , shear modulus , thickness and distance between the center of the cavity and ground surface upon the dynamic stress concentration by incident steady sh - wave 最后作为算例，给出了第一类和第二类两种不同的sh波入射方式对衬砌的散射，并选取了两种无量纲参数值，得出了圆形衬砌对sh波散射的数值结果，讨论了不同的波数比、弹性模量比、厚度比以及不同的圆形衬砌中心到水平地面距离与衬砌内半径的比值对动应力集中系数的影响。
