Introduced the second order analysis of the thin - walled members based on the theory of the rotation of a cross section around a fixed axis , and discussed the general methods of the loading capacity and the space stability coefficient for the thin - walled columns . used a programme , a large amount of space stability coefficient of t - shaped and l - shaped axes columns with a initial bend was computed to gain the curves of the columns . the procedure of the computation behaved the simplification and the convenience of the method 介绍了以定轴转动理论为基础的薄壁柱空间稳定二阶分析方法，初步论证了以此为基础的薄壁柱空间稳定承载力的验算及空间稳定系数的计算方法，并借助程序对具有初弯曲的各种“ t ”形和“ l ”形轴压柱的空间稳定系数进行了计算，作出其柱子曲线图，从而验证了此方法的可行性和简便性，同时提出以此为基础对钢结构截面优化的方法。
With the recent advent of deep submicron technology and new packing schemes , the components in the integrated circuit are often not rectangular . on the basis of the representation of corner block list , we propose a new method of handling rectilinear blocks . in this paper , the handling of the rectilinear blocks is simplified by transforming the l t - shaped block problem into the align - abutment constraint problem 尤其在深亚微米工艺设计中， ip模块的广泛使用和新的封装工艺的使用使得集成电路器件并不局限于矩形的模块，如数据电路模块data path block由于其相互关联的控制关系使其具有特殊的形状l t型，这使得电路设计中需要考虑l t型模块的处理。
After the comparison of the stability checking computations and the section categorised situation both at home and abroad the current standard , some problems was discussed in the standard of our country . contraposed these questions , the paper computed the space stability coefficient of some general t - shaped and l - shaped sections and all the sections of t - shaped , l - shaped and 2 - angle iron t - shaped in the formed - steel - table , and worked out the curves . according to the comparison of the curves the paper got and the curve in the standard , some simple conclusions was put 对国内外现行规范轴压柱稳定验算方法及柱子曲线截面分类情况进行了对比，讨论了我国规范曲线中存在的一些问题，并针对这些问题，以规范初始弯曲值对任意“ t ”形和“ l ”形截面和型钢表中所有t型钢、 l型钢、双角钢t形钢截面的空间稳定系数进行了计算，作出其与规范曲线的比较图，通过计算结果的分析对各类截面归类情况作了简单的评述，其中提出的一些建议可以作为规范修订的参考依据；同时，这些计算结果也进一步证明了本文的柱子空间稳定分析方法的正确性。
Three types of cuticular thickening at the polar region of the guard cells are observed : slight cuticular thickening ; rod - shaped culicular thickening and rarely t - shaped thickening . with data obtained from the former research and personal observation , the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted by out - group comparison using , the related genus kadsura . as result , a new system of the genus schisamdra michaux was reconstructed , and schisandra michaux was subdivided into 2 subgenus , 3 section , 2 series 10 species in this dissertation 整理有关五味子属植物研究的资料，补充搜集近期发表的资料和本人研究所得数据，以种为基本单元，选择近缘的南五味子属( kadsura )作为外类群，采用paup4 . 0b4a软件对本研究得出的性状数据作分支分析，重建五味子属的系统发育，修订和补充五味子属分类系统，在五味子属下设2亚属、 3组、 2系、 10种。
For three - short - pier shear wall under vertical loads , the results remain the same , and transfer beam at this moment will work with the middle pier , constituting a t - shape beam to sustain the moment and axial tensions together . 4 . under the horizontal loads , the inner stress distribution in the frame supported short - pier shear wall shows similarities with that of the short - pier shear wall underneath the fastened supports 4 、水平荷载作用下,框支短肢剪力墙墙肢内的应力分布形式接近于下部固支的短肢剪力墙的应力分布;转换梁承受上部墙肢传递的拉力、剪力和弯矩,当短肢剪力墙墙肢数量较多时,转换梁上、下边缘拉、压应力交替出现,剪应力的最大值处于洞口下方的转换梁体内。
We devise the block rejoining process and block alignment operation for forming the l t - shaped blocks into their original configurations . the shape flexibility of the soft blocks , and the rotation and reflection of l t - shaped blocks are exploited to obtain a tight packing . the empty rooms are introduced to the process of block rejoining 本文提出的多边形模块处理方法，能够对l t形模块进行快速有效的布局，保持其多边形构形，不仅可以处理二划分结构，同时也可以处理非二划分结构的布图结果。
The paper introduced the space stability theory based on the method of the rotation of a cross section around a fixed axis of the thin - walled member , and made some simply discursions . according to the theory , a programme was worked out to analyse [ - shaped , t - shaped and l - shaped axes columns . using the results of the programme , the paper has made the graph of the critical force changing by , and furthermore analysed the characteristic of the thin - walled members " space stability 本文对基于绕定轴转动理论的薄壁构件的空间稳定理论进行了介绍和简单的分析论证，并根据此理论编程对“ [ ”形、 “ t ”形和“ l ”形轴压构件进行了大量计算，作出其空间稳定临界力随长细比的变化曲线图，对其空间稳定特性作了一定的分析。
