Then, with the concept of accumulated failure probability, the proposed approach combines the least ? quares method with bayes " theorem, takes advantage of the parameter estimation for single weibull distribution to each derived subgroup data set, and estimates the parameters of each subpopulation. the estimates given by this paper also satisfy the maximum likelihood equation. the mean time to failure and the reliability estimation of the mixed population are given
然後通過利用累積失效概率等概念，對每個導出的子組數據集聯合運用最小二乘法、貝葉斯定理和對單一威布爾分佈的參數估計法，從而得到每個子總體的滿足極大似然原理的參數估計，給出了該混合總體平均壽命和可靠度的估計。 -
The results showed that : 115 polymorphic loci from yuzong 5 and gold queen maize population were amplified by 40 ssr primers ; the genotypic number accumulated by 40 primer amplification were 196 for yuzong 5 and 194 for gold queen ; the mean genetic distances were 0. 3834 for yuzong 5 and 0. 3397 for gold queen ; the mean observed heterozygosity was 0. 3826 for yuzong 5 and 0. 3292 for gold queen, while their mean anticipant heterozygosity was 0. 4747 and 0. 4143, respectively
結果表明： 40對引物在兩群體中都擴增出115個多態位點；累加40對引物擴增的基因型種類，豫綜5號196種，金皇后194種；豫綜5號的平均遺傳距離為0 . 3834 ，金皇后綜合種為0 . 3397 ；豫綜5號的平均觀察雜合度是0 . 3826 ，平均期望雜合度是0 . 4747 ；金皇后綜合種的平均觀察雜合度是0 . 3292 ，平均期望雜合度是0 . 4143 。 -

We researched and established data model of the site data for the main shaft bearings, and appraised its reliability life by the surviving ratio method, the mean hitch method and the accumulated hitch method
研究並建立了主軸軸承現場數據的可靠性數據模型，並對軸承進行了平均壽命的評估。 -
In part three, according to the viewpoint of system, giving consideration to all kinds of condition of forming hillslope debris flow, taking five indexes as follow : the shape index of ditch, the mean value of greatest precipitation within 24 hours, the developing degree of unstable mass, the mean depth of loose " accumulated clay and the rate of plant cover, applying fuzzy mathematics, the paper designs a suit of scheme about judging hillslope data
第三部分，依據系統的觀點，全面兼顧了山坡泥石流形成的各種條件，選取溝谷縱剖面形態指數、最大24小時暴雨均值、不良地質體發育程度、鬆散堆積層平均厚度和植被覆蓋率五個指標，運用模糊數學方法在室內設計出一套山坡泥石流溝與非泥石流溝的判定方案。然後以野外實例數據進行檢驗，結果表明本方案分辯率較高，為84 . 6 ，且偏於安全一側。
