failure density function
解釋
故障密度函數-
Based on the count of failure in the samplers, this paper analyzes the weak link of the quality of domestic automobile products. with the help of mathematical statistics and automobile reliability theory, we get the failure law of bus, truck and car of the domestic automobile industry and their failure distribution function, reliability function, probability density function, and failure rate function. accordingly, the present situation of reliability in domestic automobile products is expounded
本文通過對樣車的故障進行統計，分析了我國汽車產品質量的薄弱環節，並藉助數理統計手段和汽車可靠性理論，得出了國產客車、載貨汽車以及轎車的故障規律和相應的故障分佈函數、可靠度函數、故障密度函數及故障率函數，論述了國產汽車產品的可靠性現狀。 -
At the same time, the formulas on reliability, mean time to failure and availability, mean time between failure etc were deduced respectively based on the distribution density function and markov state - transition diagram
同時依據分佈密度函數和馬爾可夫模型的數學理論分別推導了兩種系統的可靠度、平均故障前時間和可用度、平均故障間隔時間等指標的計算公式，為軟體內核程序的開發奠定了理論基礎。 -
First, according to the definition of n - dimensional density function, this thesis decomposes it into the conditional probability about variable alone, which can be expressed by conditional failure rate function about variable alone
本文首先根據多維密度函數的定義把它分解成關于各個變量的條件概率，而這些條件概率可以由各變量的條件失效率來表達。 -
S - eeing that the analysis process is loaded down with trivial details an $ is difficulty extended in multivariate case. however, taking advantage of relation between multivariate failure rate and distribution density function built by the author and endowing conditional failure rates with reasonable value joint with the fatal shock meaning, we easily obtain three - dimensional and even n - dimensional exponential distribution
鑒于該方法分析過程繁瑣，難于得到高維情形。本文另闢蹊徑，利用建立的條件失效率與多維壽命分佈之間關系，並結合致命沖擊含義賦予條件失效率合理的值，得到三維乃至一般的n維指數分佈。
