The edge detection approach based on cp neural network is valid to overcome the randomness of fragment dispersing and complexity of distribution of perforation holes. applying neural network approach, the influence of the negative factors is reduced in artificial detection and statistics. in this way, the target image was detected exactly and successfully
基於cp神經網路的邊緣檢測方法有效地克服戰斗部破片穿靶試驗中破片飛散的隨機性和破片孔分佈的復雜性，從而減小了人為檢測和統計中諸多不利因素的影響，完成對靶板圖像的準確檢測。 -
Based on the analysis about the test requirements and the saturated magnetization of the armor plate, the excitation magnetic circuit satisfying the testing condition and a validation system are designed. because the geometric, of the magnetic leakage at the direction of the normal of the roundness fault has the feature of two peaks : a positive and a negative, using the linear regression and the software matlab, two regression equation are proposed : one is about the peak value of the magnetic leakage and the diameter and depth of the roundness fault ; the other is the distance between the two peaks and the diameter of the roundness fault. the result of the validation system proves that the two equations are valid, and an applied method using for quantificationally inspecting the roundness faults is proposed according to the two equations
根據實驗要求，通過對鋼板達到飽和磁化的必要性進行的分析，設計了符合試驗條件的勵磁磁路，並設計了一套實驗驗證系統；根據圓形缺陷法線分量漏磁場幾何圖形正負雙峰值的特點，採用線性回歸擬合的原理和matlab軟體及其統計工具箱中的相關函數，給出了圓形缺陷漏磁場幾何圖形的峰峰值與圓形缺陷的直徑和深度以及峰峰值間距與圓形缺陷直徑的兩個回歸擬合方程，並通過實驗驗證系統驗證了擬合方程的正確性，利用這兩個簡單實用的擬合方程，提出了一種工程定量檢測圓形缺陷的應用方案。 -
The frequency analysis results show conclusions as follows : 1. the relative valid spectral power is declined with the volume percentage of inclusions in terms of exponent curve and the tendency of negative direction is same to that of forward direction
當ly12鋁合金細小夾雜物（小於0 . 16mm ）的體積百分數從0 0 . 35時，在35 50mhz的頻帶范圍內，超聲波形的有效譜功率按近似指數曲線快速下降，沿相反方向檢測時其變換趨勢相同。 -
First, this text distinguishes the economic influence of the foreign loan with the negative effect and the positive effect, and explain the condition that develop the positive effect in foreign loan at the same time, to emphasize the necessity of foreign loan scale management. second, considering the contact of foreign capital with the foreign loan, and study of the foreign loan scale first is from the foreign capital scale, the text reviews and evaluates the main theories of valid scale of the foreign capital and foreign loan. third, analyze the reason, the positive and negative affect to economy of foreign loan, then summarize the foreign loan experience of representative korea and latin america. fourth, assure the condition to the valid foreign loan scale after the
本文首先從外債的正面效應和負面效應分別對外債對經濟的影響做出闡述，同時對發揮外債正面效應的條件做出說明，強調外債規模管理的必要性;其次考慮到外資和外債之間的聯系以及研究外債規模首先是從研究外資規模開始的，所以從外資和外債適度規模兩個方面對外債管理的內涵和主要理論成果進行回顧並進行評價;再次分析了我國引入外債的原因和外債引入對我國經濟發展的正反兩方面影響，同時對國際上外債規模管理具有代表性的韓國和拉美國家進行了經驗總結;接著通過對有效外債規模內涵的分析，確定滿足的條件，從理論和實際操作兩個方面建立有效外債規模模型，並進行分析，從而為有效外債規模的確定提出了新的思路;最後分別從長期、短期和實際操作三個方面對我國的有效外債規模管理提出建議，並且對長期、短期和實際操作模型中應遵守的事項做出總結。 -
