| 1. | This couldn ' t have come at a better time . researchers in italy say moderate drinking may lengthen your life , while too much may shorten it
意大利研究者表示适度饮酒可延长人的寿命，而过度则会导致寿命缩短。这一结果来得正是时候。 |
| 2. | Cheap edxrf ' s detector has one 3 - 5 year life , whose sensitivity will be down as the time pass ; high performance detector has 10 - 15years working time
低端的edxrf的检测器寿命会随着时间的使用寿命缩短，灵敏度下降，寿命在3 - 5年；高端的检测器寿命在10 - 15年以上。 |
| 3. | Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking , particularly cigarette smoking , is associated with shortened life expectancy
许多研究小组进行的研究不容置疑地表明，吸食烟草，特别是吸卷烟与预期寿命缩短有关。 |
| 4. | When it is operated in the dank circumstance , zns tend to be hydrolyzed and zn is separated out . the lifetime is decreased due to the destruction of luminescent configuration
此发光材料在潮湿的环境中使用，基质材料zns容易发生水解而析出锌，从而破坏了发光体的结构，致使材料的寿命缩短。 |
| 5. | The maximum thermal stress will rise while the thickness has been reduced , the intensity of piston will decline , and the progress of the engine power will be affected
活塞顶部厚度越小，活塞的最大热应力值也将增大，从而使活塞的强度变低，活塞的寿命缩短，影响发动机的强化程度的提高。 |

| 8. | This phenomenon makes the circumferential velocity of the driven wheel be slower than the drive wheel ' s decrease the efficiency of the belt drive abrade the belt and shorten its life . so , it is very important for those who design and use it to know and understand qualitatively and quantitatively the phenomenon of elastic slippage
弹性滑动的存在使从动带轮上的圆周速度低于主动带轮上的圆周速度，带传动效率降低，带磨损和工作寿命缩短，因此，定性和定量地认识和理解带传动中的弹性滑动现象对于带传动的设计和使用是十分重要的。 |
| 9. | In addition , under high sintering temperatures , iron powder can result in the graphitization of diamonds . these two reasons will affect the mechanical properties of the metal bond and its retention capacity . as a result , the wear resistance of metal bond is poor and diamond grits can be easily pulled out from the matrix , thereby shortening the life of the saw - blade
而且在高温下，铁粉会对金刚石产生较严重的化学侵蚀，这两方面的原因都会影响结合剂本身的力学性能及其对金刚石的有效把持，导致锯切过程中结合剂耐磨性差，金刚石容易脱落，使锯片寿命缩短。 |
