Simulated annealing of multi - parameters optimization is the simulated annealing wave impedance inversion with some constraints, including s / n ratio, adjacent - channel correlation, deviation of initial model, and threshold value of reflection coefficient
摘要多參數優化的模擬退火法波用抗反演是通過調整地震資料信噪比，相鄰道的相關性、初始模型偏差、反射系數門檻值等約束條件進行地震資料反演的。 -
The analyses given in this paper to quasi - three - level for 946 nm laser are complete. the relation between 946 nm laser transmission and optimal crystal length has been derived from the rate equations describing the population inversion and the photon density in the laser cavity in the steady - state case. the minimal claims to coating have been given on the base of contrasting 946 nm transmission with 1064 nm transmission in the condition of different cavity losses and how the pump beam radius in the laser crystal and optimal crystal length affect the laser threshold and output power of 946 nm laser has been given as well
對產生946nm譜線的準三能級結構給出了較為完整的分析，利用激光諧振腔處于穩態時的速率方程，導出了準三能級nd ： yag946nm起振時，透射損耗與最佳激光晶體長度的關系，在與1064nm透射損耗相比較的基礎上，給出了不同的腔損耗情況下的最低鍍膜要求，並且給出了激光閾值、輸出功率和最佳激光晶體長度及泵光光斑大小的關系，這為設計室溫下高效運轉的946nm激光器的提供了理論基礎，這種分析方法對研究此類低增益，準三能級或三能級激光系統輸出特性有借鑒意義。 -
