| 6. | Structural modifications focus on increasing the minimum life of the wing main spar ( originally set at 800 hours ) have carried through several proposed progressive stages of modification with the intention of reducing fatigue problems and providing a life extension of up to 1 , 250 hours for a complete refurbishment with a newly manufactured main spar
机体结构上的修改着重于延长主翼梁的最低寿命（ 800小时） ，以进行多次渐进式阶段的改造方法来达到减少疲劳和延长寿命至1250小时的目标。 |
| 7. | Therefore , the structural modification of n - glycan and the functional changes of egf receptor ( egfr ) in different transfected cells were investigated . it was found that the 1 , 6 glcnac branch on the n - glycans of immuno - precipitated egfr on gntv - s / h7721 cells was increased while it was reduced in gntv - as / h7721 cell despite the unaltered expression of egfr protein
因此本文对不同转染细胞egf受体( egfr )的糖链结构及功能的改变作进一步研究，结果发现，不同转染细胞中，免疫沉淀egfr的蛋白量没有改变，但gntv - s h7721细胞egfr上n -糖链中1 ， 6glcnac分支比mock细胞增多，而gntv - as h7721细胞相反。 |
