老化

The hygrothermal aging behavior of the CF /epoxy NOL rings in distilled water at 35℃, 55℃, 65℃and 75℃was analyzed in terms of the absorption characteristics, static and dynamic mechanical properties.

本论文旨在碳纤维缠绕复合材料压力容器的加速湿热老化方案的设计以及储存寿命预测提供基础数据，并对其寿命预测进行初步研究。

It is shown by Infrared spectra that relative concentration of amino formic acid ester has prominent relationship with compressive stress at 10% strain in the process of accelerated hygrothermal tests, which means that hydrolysis of amino formic acid ester is main factor resulting in decrease of compressive properties.

经红外光谱测定，在人工加速湿热老化试验过程中，材料的活性基团氨基甲酸酯的相对浓度与10%定应变压缩应力的相关性显著，氨基甲酸酯水解是材料室内贮存过程中力学性能下降的主要原因。

Many of the issues, which arise in teaching practice, are closely related with the imperfect teachers' qualities. The universal problems of primary-school teachers are the deficiencies of advanced educational theoretical knowledge and scientific research ability, the outdated knowledge structure, the inadaptation to the need of quality-oriented education, the low ability level of computer , English and employing modern educational technique, the lack of comprehensive ability, especially comprehensive liberal arts and comprehensive science, and the great difficulty in establishing selective courses and activity courses.

毋庸质疑，我国的师范教育还比较落后，小学基础教育师资的整体水平还不高，教育实践中出现了各种问题，例如：有些教师缺乏先进的教育理论知识；知识结构老化；不适应素质教育需要；计算机、外语能力差；运用现代教育技术手段的能力差；综合能力欠缺，特别是综合文科、综合理科的能力欠缺；等等。

In accordance with the ageing of most electric equipment s of the mining area of Jiaozuo Mining Group,the lower natural power actor and the increscent energy cost per ton,the method of improving the natural power actor was introduced.

针对焦煤集团矿区的大部分用电设备的自然功率因数都较低，设备老化，吨煤能耗增大等问题。

The case is unpleasantly similar to one two years ago involving another tissue broker, this one from New Jersey, who also sold ineligibly old or diseased tissue including bone from the cancer-ravaged, 95-year-old corpse of the British radio journalist Sir Alistair Cooke.

此案是两年前另一位人体组织经纪人案的翻版，后者来自新泽西，他从终年95岁、死于癌症的英国电台记者阿里斯泰尔？库克爵士的遗体上购得并随后出售包括骨骼在内的老化、患病组织。

By adding appropriate copper stearated, melamine, the PVC U products have excellent properties of pulverization preventing and ageing resistance such as inoxidizable, uvioresistant, weatherproof, ageing resistant properties, and excellent heat stabilization.

在户外用PVC U型材配方中加入适量的硬脂酸铜和蜜胺，既可防止PVC U表面的粉化现象，同时又能抑制其耐热老化性能的降低。
