说明：需改动的地方比较多，一一描述实在太费功夫，麻烦楼主对照一下即可。已在原翻译基础上做了修改，可以放心采用。从具体技术角度分析Analysis from the angle of specific technology通过走向图我们可以清楚的看到一项具体技术的发展变化，比如在松下公司拥有多项基础专利、核心专利的储氢合金技术方面，1990-1995年主要采用的是利用难熔金属与还原金属来储存氢，而1996年在此基础上发展了新的难熔合金，1999年则尝试通过热处理技术和改变有色金来储存氢，2000年则是通过对金属粉末加工来达到储氢的目的。From the trend chart we can clearly see the development change of a specific For example, the hydrogen storage technology which Panasonic owns many basic patents and core patents, from 1990 to 1995, it mainly used refractory metals and reducing metal to store hydrogen, and in 1996 Panasonic developed a new refractory alloy on this basis, In 1999, Panasonic tried to store hydrogen by heat treatment technology and changing nonferrous metals, and in 2000 it tried to achieve the goal of storing hydrogen by processing metal 电极技术方面也是如此，从最初的镍、钴、铁到之后的碳基电极，松下公司尝试着使用多种材料用于电极技术的开发。It is also the case for electrode technology, from initial nickel, cobalt, iron electrodes to subsequent carbon-based electrodes, Panasonic tried to use various materials for the development of electrode 在经过长达10年的储氢合金与电极技术研究之后，松下选择了向制氢技术领域发展，并且曾在1998年采用金属氢化物来提取氢，而在2001年之后，提取氢的技术已转向使用氢混合物。After 10 years of research on hydrogen storage alloy and electrode technologies, Panasonic chose to develop hydrogen production technology, and tried to extract hydrogen from metal hydride, and after 2001 the hydrogen extracting technology has been switched to use hydrogen
