The positron lifetime spectra were measured for the dehydration by pumping vacuum or by heating for USY samples respectively. Comparing with NaY, the results show that it is necessary to use four components to characterize Y zeolite with faujasite structure, and it needs another, i. e. the fifth component, to show the micro-structure information of the secondary pore for the Y zeolite which include much secondary pore.

测量了USY真空脱水以及加热脱水过程的正电子寿命谱，并与NaY的测量结果相比，结果表明：对于具有八面沸石结构的Y沸石需要用四个寿命分量来表征，对于含有大量二次孔的Y沸石还需要用第五寿命分量来表征二次孔的微结构信息。

Last month, a UK insurance company Lucida announced the first longevity swap transaction based on the LifeMetrics index, agreeing to pay JPMorgan an income stream based on current longevity expectations in return for JPMorgan's promise to pay an income stream based on how long people actually live for.

上月，英国保险公司Lucida宣布了首笔基于LifeMetrics指数的寿命掉期交易，同意根据目前的寿命预期向JP摩根支付收入流，以换取JP摩根的承诺：根据人们的实际寿命支付收入流。

It is found that the lifetime of excited states is monotonically reduced with decreasing quantum-well width,from 350 ps in bulk to 55 ps in a 100 ?

实验结果表明：随着量子限制效应的增强，受主激发态寿命而减少，实验测得体材料中Be受主2p激发态的寿命是350 ps，而阱宽10 nm的多量子阱中的寿命是55 ps。

Present multiaxial fatigue life analysis method are discussed, and show that equivalent stress-strain approach based on uniaxial fatigue life analysis method can not predict low-cycle fatigue life under nonproportional cyclic loading.

对现有的多轴疲劳寿命分析方法进行了讨论，论证了以单轴疲劳寿命分析方法为基础的等效应变法不能预测多轴非比例加载下的低周疲劳寿命。

The fresh weight and basal diameter of the cut curcuma flowers decreased with time after harvested without inserted them into water immediately. Thus, the vase life decreased. The even of the off-water time is only 30 minutes. One gram of fresh flower can absorb 30-40mg of fresh water, and the vase life increased 2-4 days if the stem base were recut, The curcuma flower per se after carting didn't posses peak of respiration and release of ethylene as well.

姜荷花切花采收后随著离水时问增长，鲜重与花茎基部直径渐减，瓶插寿命亦随之缩短，离水仅0.5小时切花即明显受要影响，花茎基部重新切除可增加10-20mg/gF.W的吸水量，而延长瓶插寿命，但同样随著离水时间延长而降低瓶插寿命。

Take the 10~12ml single-valve capacity as the example, with flings turns the head to separate evenly, 36.000rpm 60 the hour, turns the head with the angle type to separate 45, OOOrpm 36 the hour, the former including adds the deceleration to use in common 130,000,000 revolution of actuation department lives, the latter must use 100,000,000 revolution of actuation department lives, this was 100 ~ 20,000,000,000 transfers to at that time the supercentrifuge total life looked, without doubt each time tests the expense to be excessively high, in addition the CsCl amount used are many, price expensive and so on factors, causes this kind of separation purification work to become the very expensive experiment.

以10~12ml单管容量为例，用甩平转头分离，36.000rpm 60小时，用角式转头分离45，OOOrpm 36小时，前者包括加减速在内共用去1.3亿转驱动部寿命，后者也要用去1亿转驱动部寿命，这对当时超速离心机总寿命为100~200亿转来看，无疑每次实验费用过高，加上CsCl用量多、价格贵等因素，使这类分离纯化工作成为非常昂贵的实验。

Tension-tension fatigue experiment was carried out at three different stress-level, the fatigue life and the S-N curve of the unnotched laminates were acquired.

进行了三种不同应力水平下的拉-拉疲劳试验，得到无孔试件的疲劳寿命及其S-N曲线；通过研究复合材料疲劳寿命预测的方法，建立了该无孔层合板剩余刚度疲劳累积损伤寿命预测模型。

Second Life users, and various Linden Lab staff are referring to this as 'a revolution', likening it to the original Second Life Tax Revolt in 2003, which was in a large part responsible for the formation of the modern Second Life economy as it stands today.

第二个寿命使用者、和各种不同的菩提树实验室职员正在提及这作为'革命'，在 2003 年对最初的第二寿命税叛乱比喻它，这是在一大大地部份有责任为现代第二的寿命经济的形成，当它今天站着。
