Physical model of computer box is established and through analyzing the changing curves of change of electromagnetic field with time and change of coupling coefficient with frequency, the coupling regulation of electromagnetic on computer box is obtained. It is as follows: electromagnetic pulse has a great effect on components of computer box through apertures and slots, the coupling energy in the box increases first and then decreases. The existence of components decreases the shielding effectiveness and resonant frequency.

建立计算机机箱的物理模型，通过分析机箱内的电磁场随时间的变化曲线和耦合系数随频率的变化曲线，得到电磁脉冲对计算机机箱的耦合规律：电磁脉冲可以通过孔缝进入机箱内部，对机箱内元件的瞬间影响较大；机箱内的耦合能量是先增加后减小；元件的存在使得机箱的屏蔽效能降低，谐振频率下降。

On the basis of foreign research achievements, two kinds of domestic cold-formed steel sections are used as the parent materials to design Rosette-joints. Different styles of joint and various influencing factors (including form of hole, aperture, and the edge distance from the center of joint to the edge of the sheet) are taken into account, and four series of test specimens are schemed out. A series of axial-tension tests on all test specimens are carried out to investigate the shear strength of every rosette-joints.

本文结合国外的研究成果，采用我国常用的两种较大尺寸的冷成型钢型材作为母材来设计插座式连接，考虑了节点的不同形式以及影响节点承载力的各种因素(包括孔形、孔径、端距等)，设计出四组不同形式的节点试件，并对各组试件进行轴向拉伸试验来考察各种类型插座式节点的抗剪承载性能。

Simply shortening a suit's hems and sleeves can leave the collar too broad, the pockets oversized, the armholes gargantuan, the elbow curves too low and the rear droopy.

仅仅修短衣服的下摆和袖子是远远不够的，领口、口袋、袖孔都还是太大，肘弯处太低，后摆也是耷拉着的。

Stamens included; filaments flattened, usually dilated towards base; anthers oblong, dehiscing by terminal pores, with 2–4 awns or minute projections.
