老化

The application of this method will improve the study of age and degradation of polymer material.

根据自适应过滤法的特点，将其用于高分子材料老化与降解的研究，对我们的研究工作将起到推动作用。

Methods: We divide the rats into 5 groups in random, with Morris method, detect the change of some active oxygen radicals such as super-oxide demitasse, Nitric Oxide Synthase, malondialdehyde etc. Also, we detect the change of cholinesterase, Monoamine Oxidize; using HE,PAS staining, immuno-histochemical technique, detect hippocampus CA1 cerebral pathology slices optical density value of NOS, CHE and lipofuscin of neural cell; detecting apoptosis rate and the expression of P53 , which are neuronal apoptosis related genes.

大鼠随机分为5组，采用"Morris水迷宫"法观察脑缺血性模型大鼠学习记忆功能，检测超氧化物歧化酶、一氧化氮合酶、丙二醛等自由基代谢异常的改变，检测胆碱酯酶、单胺氧化酶等老化相关酶的变化、脑组织神经细胞免疫组织化学技术、检查海马CA1区脑组织的病理切片，检测NOS、CHE光密度值；流式细胞技术：检测细胞凋亡率，及促细胞凋亡基因、P_(53)蛋白表达；病理切片采用HE染色、PAS染色及免疫组化法检查，检测对大鼠海马神经元细胞一般病理变化及脑细胞内脂褐含量。

"It really raises the question of what should be considered normal ageing," says Kenneth Manton, a demographer from DukeUniversity in North Carolina.

"这真的引起的问题是什么，应该认为是正常的老化，说："丁 manton ，人口统计学家，由杜克大学，在北卡罗来纳州。

The aging or denaturalization can not happen in the CSP when phase system was transformed, so it has some stability.

所制备的CSP在相体系转化时不发生老化和变性，显示了一定的稳定性。

So you can derive the age of your battery.

所以你可以推导出你的电池老化。

Results revealed that the large side insulation of the stator bar in slot is available for ultrasonic pulse-echo testing; Coupling transducer on the surface of a practical stator bar could minimize the influence on the measurements of velocity, contributing no destructivity of the ultrasonic testing for stator insulation; The simultaneity of same velocity and higher attenuation can be used to detect insulation delamination from conductors; Compared with the wide sides of the bars in slot, the short sides of the bars near the exit from slot and the end bars had a same velocity and a higher attenuation; The velocity might be exactly measured on the shot sides of the bars near the exit from slot and the end bars, while the attenuation might not, which were examined though filed tests; V min decreased greatly and V av decreased slightly with the service time of the bars.

在实验室对线棒多种结构处的主绝缘和不同运行年数(未老化、16、18 和23年)线棒的主绝缘进行了低频超声反射法检测试验，并进行了现场试验，发现(参见 Hao et al， IEEE DEI， to be published)，槽部线棒的宽面绝缘不受换位绝缘的影响，比窄面绝缘更适合超声测量；线棒表面平滑的半导体层减小了耦合剂对超声测量的影响，实现了无损性；波速不变而声衰减减小可以检测线棒出现绝缘与导体脱壳缺陷；出槽口和端部线棒的窄面绝缘与槽部线棒的宽面绝缘相比，声衰减大而波速一致；现场试验验证了波速不受绝缘结构和现场测试条件的影响，而声衰减受以上因素影响很大(参见 Hao et al，中国电机工程学报， Vol.23 No.4)； V min 随运行年数明显减小， V av 随运行年数慢慢越小。

It is inevitable that such a mechanism is subject to a certain amount of deterioration over time.

无可避免的，这样的机械装置随着时间的推移会有一定的不见老化情况发生。

In this paper,with the aid of discontiguous diagnostic technology and method of accumulated damage using accelerated aging or heat air-oven the critical service life was determined and the service life for CMDB solid pram Pedant was predicted'The results in this paper are of practical significance for service life prediction of solid rocket grain.

采用药柱空穴率非接触诊断技术和热加速老化累积损伤法，实测得CMDB固体推进剂的贮存寿命失效临界点，预测了其使用寿命。

In the culture phase, a great deal of protease, lipase,α_amylase and diastase were accumulated on the skin of beancurd. After 36 h, the thallus began to decay and the activity of all these enzymes began to decline.

培菌阶段在豆腐坯表面积累了大量的蛋白酶、脂肪酶、α_淀粉酶及糖化酶，培菌36 h后菌体开始老化，酶活有所下降。

Within a decade, its rapidly aging population will suffer a severe labor shortage, and China will have millions of elderly people with few kids, and a Dickensian social system, to care for them.

在十年内，它迅速老化的人口将面临严重的劳动力短缺，而且中国将有大量老人，却没有多少孩子照顾他们，一个狄更斯式的社会体系。
