失调量 meaning in Chinese
misalignment rate
Examples
- Among the adaptive beam - forming algorithms , the least mean square algorithm is widely used because it has a simple configuration and it is apt to come true and have nice convergence . on the other hand , it has a disadvantage that it converges slowly and there is a conflict between the fixed step and the convergence pace or the error in stabilization . so people have developed many improved least mean square algorithms which generally start from convergence , stabilization , misadjustment , and robustness and come to a formula about variational step in the end
在自适应波束形成算法中，最小均方( lms )算法因结构简单，易于实现，能稳定收敛而得到广泛应用，但它也存在收敛速度受限的缺点：固定步长因子无法解决收敛速度和稳态误差之间的矛盾。因此，人们提出了各种改进的最小均法算法来解决这一问题。改进的最小均方算法通常从如何改进收敛速度、稳态误差、失调量和鲁棒性等指标上出发，最后在新算法最终表达式中的步长公式上变化。 - So a computer - aided alignment method for a series of reference lens is studied in detail in this paper . based on analyzing the optical quality affecting factors and optical design , the folio wings are described in detail in this paper : ( 1 ) how to choose merit function of optical quality in terms of the specific reference lens , and sensitive structure parameters to optical quality would be determined according to their tolerance data ; ( 2 ) discussing the relationship between the aberrations and the misalignment of reference lens ; ( 3 ) building the mathematical model for the misalignment optical system , and then calculating the misalignment value by the alignment software compiled on zemax and matlab platforms ; ( 4 ) experiments are made to examine the computer - aided alignment method . the theoretical and experimental data and plots are given in the paper
