Journal of Rare Earths 1995年第4期13卷 295-301页

作者： McMasters O.D. ETREMA products inc Ames United States

The development of the giant magnetostrictive rare earth-iron materials is reported from their discovery in the early 1970's to their present use in transducer and sensor applications. Fifteen broad market areas, ranging from miniature devices in the medical industry to high powder sonar and seismic sources have been identified. A world-wide customer base in these high technology fields has been established and the superior properties of these materials are responsible for the rapid growth of the magnetostrictive transducer industries. The critical design criteria that lead to efficient devices are reported and the performance of several of these products is presented. The key patents associated with these giant magnetostrictive materials and devices using these materials are reviewed. The present and future of these technologies in reference to commercialization, market growth and the impact on the many transduction industries are discussed. (Author abstract) 9 Refs.

作者： Alec M. Makdessian maxim integrated products inc

在大多数应用场所,尤其是工业应用环境,电流模式通常是优先考虑的信号传输方式,一般采用常见的2线4-20mA的电流环,通过一对双绞线既向模块供电,又传输信号。另一种使用较少的模式是3线制,它的优点是能够向模块输入更大的功率(2线制系统... 详细信息

在大多数应用场所,尤其是工业应用环境,电流模式通常是优先考虑的信号传输方式,一般采用常见的2线4-20mA的电流环,通过一对双绞线既向模块供电,又传输信号。另一种使用较少的模式是3线制,它的优点是能够向模块输入更大的功率(2线制系统的最大允许工作电流仅为4mA)。

人们对D类放大器的日益接受帮助它们从线性AB类放大器那儿赢得了市场份额。这种接受并不令人吃惊．D类放大器的优点很多，但这类放大器也需要新的评估方法。以线性放大器的基本正弦波测试为例。加电．向输入端施加合适振幅的正弦波．并把示波器探头连到输出端。将会看到输入的复制品，通常偏移半个电源电压。即使线性放大器驱动BTL（桥接负载），也仍会在负载的任何一端看到可识别的输入复制品，尽管是可用输出信号的一半。
