  gain level
It was found that the reaction temperature has no significant effect on dimensional stability provided the same weight gain level is obtained.
      
By adjusting the power combination of pumps 1 and 2, the clamped gain level can be controlled.
      
Gain settings were optimized for image quality with the maximal color gain level that would not introduce signals outside areas of flow.
      
If the amplifier gain level is not controlled, the first oscillation condition is reached by saturation.
      
It basically describes a very high gain level that causes a slight distortion of the incoming signal, resulting in a warm, rounded sound.

In conclusion, flow volume can be accurately measured by Doppler power imaging. The method has the potential value for the quantification of tissue perfusion and neovascularity of malignancy.

本研究的目的在于建立应用Doppler能量图进行血流量测定的方法。应用标准预设的超声Doppler能量图测定体外模拟循环系统管道内流体的Doppler散射能量,观察一定液体浓度及Doppler增益水平时管道横截面上Doppler能量信号变化。利用计算机辅助图像处理求得各水平的管道截面上平均能量强度(彩色亮度),并与实际流量对比。结果显示在一定的增益浓度水平,管道截面上平均能量强度与实际流量之间存在直线相关关系(P值<0.01)。本研究证明在适当的图像设置条件下Doppler能量图能较准确地反映血流量变化的信息。此方法在组织灌流、肿瘤血管定量分析等领域有潜在的应用价值。

In broadband (~35 nm) EDFAs, gain flattening filter can be inserted between the two stages of EDFs. In this paper, an iteration algorithm for designing the filter′s transmission function is proposed. The principle of this algorithm is taking the advantages of homogeneous broadening and gain compensation between two stages. In each iteration step, the average gain level is taken as reference, and within the wavelength range where the gain is higher than the reference, an inverse gain spectrum is used to modify the transmission function. Then the gain within other wavelength range will be compensated automatically. Simulation results show that by using this iteration algorithm, the flattened gain can reach the possible highest value of the original amplifier, and noise penalty is the minimum.

针对在两段掺铒光纤中插入滤波器实现宽带 (35nm)增益平坦的滤波器透过谱的设计问题 ,提出了一种新的迭代算法。其原理是利用放大器的均匀展宽特性和级连放大器自动增益补偿的特性。在每次迭代中 ,都取要求带宽内增益 (分贝数 )的平均值为参考轴 ,在增益比该轴高的波长范围内再附加一与增益谱反对称的损耗谱。而增益低于参考值的波长处则会得到自动的增益补偿。模拟计算结果表明 ,用该方法得到的滤波谱能使放大器的增益平坦在原放大器可能得到的最高增益水平 ,同时因滤波器的引入带来的噪声特性恶化也最小。
