在小来流动压情况下，结构几何非线性引起了切尖三角翼的LCO，计算结果和试验值吻合较好。

For lower inflow dynamic pressures, the LCO of the delta wing is caused by structural geometric nonlinearity, and the numerical results correlate well with experimental data.

研究结果显示，切尖三角翼的L CO不仅与结构几何非线性密切相关，而且受到结构材料非线性的显著影响。

The study shows that the LCO of a cropped delta wing is not only closely related to its geometric nonlinearity, but also remarkably affected by its material nonlinearity.

粽子是一个三角形，外面是绿色的，尖尖的硬硬的，但是里面又白又软，很像是一个包着婴儿的绿毯子。

Zongzi is a triangle, the outside green, sharp and hard, but also the inside soft and white, like a green blanket wrapped a baby.
