撑杆

In this paper,a nonlinear planning method, quasi Newton multiplier method ,is introduced for the optimization of the bracing stiffness in braced frame structures with symmetric bracings.

本文针对设置有对称斜腹杆的钢筋混凝土框架－桁架结构，运用非线性规划方法拟牛顿乘子法，对框架－桁架结构体系中斜撑的刚度进行优化。

The benefits were seen particularly in the mid-afternoon, the scientists said - at a time when many of us can be found rifling through desk drawers looking for matchsticks to prop open our eyelids.

科学家们表示，睡午觉的好处，在下午3点左右表现得尤其明显——在这个时候，我们中的许多人都在&洗劫&抽屉，寻找火柴杆似的东西来撑着眼皮。

By supporting schemes comparison, considering of characteristics of foundation excavation and geological conditions, arch selfsupporting technology is adopted.That is shallow mining steel grid technology compounding with partial soil nails, anchors and pouring concrete scheme.

通过旋流井支护方案比选，考虑基坑特点、工程地质条件，采用拱形自撑技术，即浅埋暗挖钢格栅工艺、局部加土钉锚杆喷射混凝土支护方案。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
