In order to reduce the natural aging time of 2024 aluminum alloy, a new artificial aging technique of 2024 which aging time is shorter than that of the natural aging technique, based on the hardness and conductivity test and aging principle analysis, was proposed in this paper.

高立柱 ，刘艳红，田秀云为缩短2024铝合金的自然时效时间，本文通过对2024铝合金导电率和硬度实验研究以及对它的时效机理的分析，初步确定了2024铝合金的一种新的时效时间较短的人工时效制度。

During aging, Gastel index which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.

彩色沥青老化过程中，沥青胶体不稳定指数对沥青老化条件很敏感，随老化温度的升高和老化时间的延长而增加；粘度随老化时间的延长近似呈指数关系增加，所以可以用胶体不稳定指数和老化指数来评价彩色沥青的老化性能。

This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。

CFacing to 21 century,that of our thinking and knowledge aboutpopulation aging must be outdate with the global fertility decline,and akind of the population aging which can be better expressed"the increaseof median age or mean age"of population aging itself and human'slongevity will be emerging,that is so called"aging of the aged".

面对新世纪，随着全球生育率的持续下降，以往我们所认知的那种"老龄化"将会渐渐淡出，而一种能更好地体现老龄化"增龄"本意并反映人类长寿现象的新形式的老龄化将日益凸现，这就是人口的"高龄化"。

It is shown that Mn and Ti had refined the microstructure,and formed to precipitation affluent of Mn or Ti ,which approved the performance of the Shape Memory Alloy.For a certain strain,the shape memory effect vayied functionly together with the aging time:alloy performance the best coorperative status that the martensite lathing was close and ordered,the precipitation rich of Mn and Ti dispersed orderly in the microstructure and little or even no eutectoid phase had precipited in the alloy ,in a special aging temperature and time. With the prolonger of the aging time,the different aging time affects the microstructure rulely.

结果表明：Cu-Al-X系形状记忆合金中，Mn和Ti的加入细化了组织，并且形成了富Mn和富Ti相，起到沉淀强化和弥散强化的作用；对于同一种变形量，合金在母相时效时，形状记忆效应随时效保温时间呈现规律性变化，不同时效温度下，合金对应一个不同的时效时间，此时合金的显微组织呈现最佳自协作状态，马氏体板条细密有序，富Ti和Al相均匀的弥散在组织中，合金中没有或很少有共析相出现，且随着时效时间的延长，在不同的特定温度下，Cu-24Al-3Mn-2Ti合金的组织会有规律性的变化。

This relationship between body composition and cognitive function in old age is still unclear, the authors write. To address this question, the researchers used data from the Chicago Health and Aging Project, a longitudinal study conducted from 1993 to 2003 in a biracial community on the south side of Chicago, with an average of 6.4 years of follow-up. The cohort included 3885 community-dwelling adults aged 65 years and older who participated in at least 2 assessments.

作者表示，年长者的身体组成和认知功能之间的关系仍不清楚，为了找出此问题的答案，研究者使用芝加哥健康与老年计画「Chicago Health and Aging Project 」的资料，从1993到2003年，在芝加哥南部的一个双种族社区进行纵向研究，平均追踪期间为6.4年，该世代包括3，885位居住於该社区的65岁以上住民，且参加至少2次评估。

The univariate analysis between successful aging and MCI shows that education, marriage ,diet , exercise, somnus conduce to successful aging; drink ,smoke ,HBP , diabetes, COPD ,arthritis don"t conduce to successful aging .The multivariate analysis show that education, marriage ,diet ,exercise ,somnus conduce to successful aging; drink ,arthritis don"t conduce to successful aging.

成功老龄组与轻度认知损伤组单因素分析表明，文化程度、婚姻、饮食、饮酒、吸烟、锻炼、睡眠，高血压、糖尿病、慢性阻塞性肺病及关节炎病史等组间具有显著差异；多因素分析的结果提示较高的文化程度、婚姻、素食饮食、锻炼、正常的睡眠促进老龄化人群向成功老龄化转变，而饮酒、关节炎病史可使轻度认知功能损伤的可能性增加。

Up to 1749 participants from the Baltimore Longitudinal Study of Aging completed tests of verbal and nonverbal memory, attention, perceptuo-motor speed, confrontation naming, executive functions, and cognitive screening measures, as well as concurrent sphygmomanometric assessment of blood pressure (for derivation of pulse pressure) on 1 to 8 occasions over 14 years.
