Then, a linear time approximation algorithm was developed, which also provided a solution with the same worst case approximation bounds as LP-approximation. 然後設計了一個非常簡單有用的可以和廿近似演算法得到一樣好的近似解的線性時間近似演算法。
Normality tests show that fire time of 105 Electric fire caps is distributed lognormally, its fire time reliabilities are respectively computed. 利用正態性檢驗方法，得出它的發火時間近似服從對數正態分佈，並計算出了相應的發火時間性能可靠度。
