When the liquid heights change, an "error" signal is produced and amplified to drive a servomotor . 当液柱高度变化时，产生一个“误差”信号，经放大后驱动伺服马达。
The relatively small reduction in stress intensity magnification factor with increasing stiffness of the stiffener . 随着加强肋刚度的增加，应力强度放大因子则相应有所减小。
Operating on the borderline of superconductivity and ordinary conductivity, they produce immense amplification . 它们在超导性和普通导电性的临界线上操作，产生巨大的放大效果。
Most of the planets, on the other hand, are magnified to clear disks by a telescope of even modest power . 然而，即使用一个倍数适中的望远镜，也能把大部分行星放大成清晰的圆面。
We may conclude that transistors will be used wherever efficient amplification required within a small space . 我们可以得出结论，凡是在小体积里需要有效放大的场合，都要采用晶体管。
Wardlaw reproduced to the same scale photographs of the vegetative shoot apex of many primitive and advanced land plants . 沃德劳以同样的放大倍数复制了许多原始的和进化的陆生植物营养茎尖的照片。
When you put on the glasses, one of the elbows that fit over the ears carries the amplified sound to the bone above the ear . 当你戴上这种眼镜时，套在耳朵上的一只镜腿就会将放大的声音传到耳朵上方骨。
Industrial design places much emphasis on previous practice or on careful scale-up coupled with a liberal sprinkling of safety factors . 工业设计十分着重过去的实践经验，或者细心地进行放大，同时选用大的安全系数。
The same procedure can be used to remove the graininess of highly enlarged photographs, which is of value e.g. in aerial photo reconnaissance . 同样的步骤可以用来去掉放大很多倍的照片上的颗粒特性，这在航空摄影侦察中是有价值的。
By reducing the feedback of the cavity, a laser will no longer be self oscillatory but it will amplify an incident wave which has triggered stimulated emission . 减小腔的反馈，激光器就不再会自己振荡，而只是放大触发受激发射的入射波。
