—12.—JL.日IJ 面 成组技术与计算机技术紧密结合是现代成组技术(GT)发展的重要标志之一。编码是将有关设计、制造和管理方面的信息数字化,以便使用计算机检索、分析和处理生产中应用的火量信息。所以,编码是实现计算机辅助GT的重要基础。重 庆 大 学 学 报 为了对零件有关生产信息作较详细的描述,现代编码系统正向着多码位方向发展。在此情况下,用手工编码工作繁锁、出错率高及效率低的弊端将会日益突出。因此,应采用计算机辅助编码。此外,机助编码时就直接将零件编码作为基本数据存入计算机,免除了将手工编码输入计算机的工作,以及输入编码时不可避免的差错。 CD—CAC一1机助编码系统是根据CD.QJBM.1编码系统(为某厂研制的零件分类编码系统,14位码,.主、付结构)研制的。采用解释BASIC计算机语言,使用IBM-PC/XT微型计算机。屏幕显示和打印输出皆用汉字。二、系统主要任务本系统能实现下列主要功能:1. 自动编码及编码改错,2....

1.IntroductionLithium-ion batteries(LIBs)have attracted considerable researchinterest during the past decades due to their high energy density andlow self-discharge[1–3].Among numerous anode materials of LIBs,tin dioxide(Sn O2)has been considered as a promising anode for LIBsdue to its much higher theoretical capacities(782 m Ah/g)than con-ventional graphite(372 m Ah/g)[4,5].However,there are still prob-lems for prac...

1. Introduction Due to higher power output and excellent cycling performance,supercapacitors (SCs) become a competitive system in the field of energy storage [1–3]. However, enhancing energy density without fading the high-power density is still a challenge for SCs. During past decades, many carbon-based electrode materials with high capacity and polymer electrolytes with high-voltage window have been used in SCs, bo...
