黄骥回答：

　　好长== 　　我翻译一些关键词好了: 　　EEPROMs:ElectricalErasableProgrammableReadOnlyMemory(可用电子方式洗、写的唯读记忆体) 　　transistor:电晶体　　surroundingcomponents:周围的元件　　temperaturesensor:温度感测器　　conducting:导通　　resistance:电阻　　approximately:大约　　impedance:阻抗　　其他有一些电子领域的专有名词(Schottky-diodes,slewrate,crosscoupling...),如果你有学过的话应该会知道；如果没有学过,不知道你的背景,在这里难以用几句话解释它们.

罗怡回答：

　　谢谢。我是学过这个的。然后您给我翻译的这些词我都认识。我希望能够有全面的翻译。连缀成句子，短文。我有图片。应该是原理图结合的。这里补充一下。希望您能抽出一些时间。帮我一下。O(∩_∩)O谢谢。
