横截面

In this study, four boundary layer flows with the same mean velocity profile (the exponent of power law is 0.30) but different turbulence intensities are first simulated, the turbulence intensities at the model height are 10%, 15%, 20% and 26% respectively.

在此基础上，对不同截面不同高度的两个建筑物间的相互干扰特性进行了系统研究，主要针对建筑物间的静力、顺风向动力、横风向动力的干扰效应进行研究，然后对两个建筑物间的干扰机理进行了详细分析。

When a ductile material is tested, the reduction in cross-sectional area due to waisting causes an increased stress without an increased force, to ensure that extension proceeds uniformly.

当韧性材料被测试时，由于颈缩使横载截面面积减小，以至在受力没有增加的情况下引起应力的增加，以保证延伸继续如常进行。

The results indicated that the cross sections of fibers were porous and the surface had many cross markings, endwise lines. The FT-IR of the three fibers were basically similar. Ramie fiber accorded to the character of cellulose I, and with the highest crystallinity.

实验结果表明，这三种纤维的截面内均有孔隙，同时表面具有横节竖纹；它们的红外光谱图基本相似；苎麻纤维符合纤维素I的特征，且结晶度最高；黄麻的耐热性能最好，其次是苎麻。

The round cross-section rods in quayside container crane are very easy to induce wind resonance,and the main form of the rod wind vibration is crosswind vibration,especially the vortex vibration.

岸边起重机川的圆截面杆件容易发生风致振动，风致振动山的主要表现形式为横风向的振动，其中以涡激振动为主。
