The inverter (2) inverts the inverter (1) and provides the carryingloadability for the output of the sensitive amplifier circuit.
反相器2对反相器1进行反相，并提供灵敏放大器电路输出的带负载能力。

Secondly, it discussed the deflection in stability of arch bridge and geometry nonlinear theory on ultimate load-carryingability.
其次，论述了关于拱桥稳定性的挠度问题和极限承载力的几何非线性理论。
3
After being set state load, optimized timbering adds support yielding deformation, increases the load-carryingability and improves the effect of controlling the surrounding rock.
