作大改变

The aerostatic bearing levitates the actuating rod with four radial air inlets on each side. The frictionless aerostatic guide can improve the actuating rod is electromagnetically driven by a fixed solenoid and a actuating solenoid. Through adjusting the axial position of the actuating solenoid, the actuating stroke can be fine regulated.

双列径向供气之气静压轴承提供致动轴作径向的支撑，其低摩擦之特性有助於提升定位精度，致动轴两端外侧设有固定线圈与致动线圈，调整致动线圈轴向位置可以改变致动器最大行动范围。

Fish-bellied cable truss of point supported glazing has been widely used for the characters of lightness and transparency. And commonly it is systematically supported, when additional support is added, the structure is turned from symmetrical support into unsymmetrical support, the mechanical performance will be changed greatly because of its weak ability to resist unsymmetrical deformation, and more discussion will be needed.

点支式玻璃幕墙鱼腹式索桁架结构由于其轻盈、通透的特点得到了广泛的应用，其一般都是对称支承布置，当结构由对称支承变为非对称支承时，由于其抵抗不对称变形的能力较弱，结构的力学性能会发生较大的改变，需要作进一步的探讨。

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。
