中文拼音 [jiēchéngfēnbù]
階乘分佈
英文
factorial distribution-
The normalized factorial moments ( nfm ) show good scaling properties in isotropical partition of phase space ; the nfm ' s projected into three directions versus the. partition. number appear, to be saturated curves with similar in scaling behavior ; and the three hurst exponents are very close to unity. the levy - stability holds for the q = 2 ~ 5 order moments in 3 - dimensional phase - space
發現：三維歸一化階乘矩（ nfm ）的分佈呈現出很好的標度特性；階乘矩在各個方向上的一維投影呈現出彼此十分相似的飽和曲線，且特徵參量hurst指數都接近於1 ；高維相空間各階階乘矩的分佈滿足l vy穩定性的要求。In the aspect of blind - identification, the mutual power spectrumx time - frequency distribution product of two delay signals are used as the features of classification. the cluster analysis and cumulant invariants of mpsk signals are used to automatically classify communication signals
在信號識別中，選取信號的互功率譜、時頻分佈、 mpsk信號的延遲相乘信號作為分類特徵，利用模式識別中的聚類分析以及mpsk信號的基於高階累積量構成的分類特徵不變量實現了信號調制類型的自動分類。On the contrary, the fractal in space - time evolution in e + e - collisions turns out to be self - similar, which is due to the isotropy of qcd dynamics
另一方面，在e ~ + e ~ -對撞所產生的末態粒子階乘矩的分佈中呈現出各向同性，表明時空演化中的分形結構為自相似。This thesis introduces the key technique of the us military distributed information system, with focuses on algorithms about related navigation of military tactics. kalman filtering combined with least square method is proposed for the current military development stage. the method of observation result including velocity component minimizes the convergence time, improves the positioning precision and acquired satisfied experiment results, which makes the pla independence of the us high - tech equipments
本文簡要介紹了現階段美軍在戰術信息分佈系統實現中所採用的關鍵技術，重點對戰術飛機相對導航的各種實現演算法進行了深入探討，針對我軍當前在該系統領域中的技術現狀，提出了以最小二乘法輔助卡爾曼濾波，濾波過程中觀測量加入速度分量的方法，縮短了導航濾波起始階段的收斂時間，提高了定位精度，在工程上取得了較理想的實驗數據，在一定程度上擺脫了我軍在相對導航領域對美軍先進技術裝備的依賴。分享友人
