在电力现代化建设中，提高发电机发电效率是其中重要的一环，氢气作为导热性冷却介质广泛的应用于发电设备，作为冷却剂，它可以有效地提高其发电效率，但它又是一种易燃易爆气体，所以使氢气参数处于正常范围，保证发电机高效、安全正常工作就变得至关重要，因此对氢气参数进行实时监测有着重要的意义。 本论文研究和开发了 ...

BGA布线指南 BGA CHIP PLACEMENT AND ROUTING RULE BGA是PCB上常用的组件，通常CPU、NORTH BRIDGE、SOUTH BRIDGE、AGP CHIP、CARD BUS CHIP…等，大多是以bga的型式包装，简言之，80﹪的高频信号及特殊信号将会由这类型的package内拉出。因此，如何处理BGA package的走线，对重要信号会有很大的影响。 通常环绕在BGA附近 ...

Abstract: Most magnetic read head data sheets do not fully specify the frequency-dependent components andare often vague when specifying other key parameters. In some cases, the specifications of two very similarheads from two different manufacturers might be quite different in terms of parameters ...

A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Tur ...
