Daily maintenance of computer this paper focuses on the research of soft, hardware, the computer's performance into full play, life is the maximum increase.
本文重点研究计算机软、硬件的日常维护，使计算机的性能得到充分的发挥，寿命得到最大限度的提高。
The delayed elastic deformation stage came later, the bend deflection increased more quickly, and breaking life shortened with the increase of the prolongation of the maximum load hold time.
随着最大载荷保持时间的增加，塑木复合材料进入延迟弹性变形阶段越晚，弯曲挠度增加越快，断裂寿命降低。
So the increase of 12 years in maximum life expectancy during the 20th century was just one-third as large as the increase in average life expectancy during the period (36 years).
因此，20世纪最长寿命12年的增长幅度只不过是同期平均寿命增幅(36年)的三分之一。
The results showed that:fatigue life significantly reduced as the maximum depth of dent increase;
结果表明：最大凹陷深度的增加使立管的疲劳寿命大大减少；
