To determine the principal maximal stress-strain cycle of engine components is an important step in research on engine components' life.
确定发动机零部件的最大应力应变循环是进行零部件寿命研究的重要内容之一。

The major reason for such low values is the fact that most crop plants display their maximal photosynthetic efficiency for relatively brief periods of time during the life cycle of the plant.
这样低值的主要原因是，大多数作物只能在整个生命周期中相对短的时期内表现出最大的光合效率。

The result shows that using the residue stress we can calculate accurately the maximal stress-strain cycle, which is the main factor influencing component life.
