限幅器

A bridge limiter is a bridge circuit used as a limiter circuit.

桥式限幅器用桥式电路作为限幅电路。

The experiment and test results are in good accordance with the requirements and performance data of the limiter.

实验测试结果表明，限幅器完全达到技术指标要求。

The result indicates that the output power oscillates and weakens along with increasing input power,and its oscillation period depends on the distance between the medium and beam focal point.Limiter′s limiting ability will decrease if waist size of the incident Gaussian beam and the aperture size increase.With a fixed input power scope,medium′s best limiting position will move towards the focal point if waist size of Gaussian beam and the aperture size increase,but the best limiting position will change a lot with different input power scopes.

结果表明：限幅器的出射功率随入射功率的增加衰减振荡，其振荡周期取决于介质相对于光束焦点的位置；限幅器的限幅能力随入射光束腰半径和光阑孔径的变大而减弱；入射功率范围固定，入射光束腰半径和光阑孔径增大时，介质的最佳限幅位置向入射光束的焦点靠近，但是在某些入射功率范围内会存在多个最佳限幅位置；光限幅器的箝位输出功率随光阑线性透过率的增加存在线性增加和非线性增加两个不同区域，实际应用中应在线性增加区域确定光阑孔径的大小。

When this button is in the Out position, the 166XL operates as a hard knee compressor/limiter. Yellow OverEasy LED is active only in OverEasy Mode.

当这个按钮处于这个位置之外时，166XL就像硬拐点压缩器/限幅器那样处理（黄灯仅在OVEREASY模式时激活）。

As a example, four kinds of switch structures are discussed, numerical results show that the off/on extinction ratio can be less than -90 dB and the dynamic switching range can be less than 0.03 Pc/100, and as an optical stabilizator, the fluctuation of the limiting power level can be less than 10-7Pc.

数值分析表明，级联耦合器作为全光开关，消光比可小于-90 dB，动态开关区可小于3×10-4 Pc；作为光功率稳定器和光学限幅器，其输出光功率起伏可小于10-7 Pc。标签非线性耦合光开关光限幅器 nonlinear coupling optical switch optical limiter

The main parameters for the reception path is a very low noise figure (2dB typical including the duplexer and the limiter losses), the amplitude/phase control with a very high accuracy.

接收支路的主要参数是很低的噪声系数(典型值是2dB，包括收发开关和限幅器损耗)，以及很高精度的幅相控制。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
