The vehicles will have to provide substantial savings over petrol-powered alternatives, not just over their life-times, but upfront. 这些车必须比汽油驱动汽车更加省钱&不仅是就使用期间而言,还包括前期费用。
Reliability Survey of G-PH Type CIMS Production Line with the Phase Type Life-Times 有相型寿命G&PH型CIMS生产线的可靠性研究
This paper studies the stochastic structures and properties of G-PH type CIMS production line with the phase type life-times by using analysis theory of phase type structure matrix. 利用位相结构矩阵分析理论,研究了具有相型寿命G一PH型CIMS生产线的随机结构和性态。
