电子技术与液压技术

<P>电子技术与液压技术是一对矛盾的兄弟,一方面,电子技术的进步,特别直线电机得出现,使得液压技术又多了竞争对手,而且在许多方面都对液压技术造成了影响,另一方面,电子技术与液压技术的结合,又拓宽了液压的应用范围,也提高了技术水平,当前电液结合的液压元件是液压技术发展中的一个亮点。下面的材料是一些电液结合方面的资料,希望对大家有所帮助。</P>

Re: 电子技术与液压技术

外国人真黑,淘汰的给我们,高端的全掐在自己手里.
也不怪人家,我们自己也忒不争气,普通阀还做的磕磕绊绊的呢.
我搞阀的时候,不是材料没有就是加工不出来,直到现在,我们的弹簧质量仍不稳定.做了几十年了都,一点进步都没有,提起这些事就发堵.
