The SWNT-based capacitors also have good charge/discharge reversibility and cycling perdurability. 基于SWNT的超级电容器也有着良好的充放电可逆性和循环稳定性。
The existence of hydrogen bond within or between the molecules of pigment can enhance the perdurability, light fastness and weather resistance. 分子内和分子间氢键的存在可提高颜料的耐久性、耐光性和耐气候牢度等。
It has the features of simple structures,desirable appearance,convenient and quick loading and unloading,use of safety and reliability,hygiene and perdurability etc. 它具有结构简单、外形美观、装拆方便快捷、使用安全可靠，卫生条件好和经济耐用等优点。
With the development of building technology, the need of construct materials is more and more, especially to the high strength and long perdurability of concrete. 随着建筑技术的发展，人们对结构材料的要求越来越高，尤其是对混凝土的高强性和耐久性的要求越来越高。
In the past few years, with the development of building technology, the performance demand of construction materials is more, especially to the high strength and long perdurability of concrete. 在过去的十几年中，随着建筑技术的发展，人们对结构材料的要求越来越高，尤其是对混凝土的高强性和耐久性的要求越来越高。
