说明： This article introduces two new configurations for precision current sources and current mirrors. Both
circuits use n-p-n bipolar devices, but one provides a current source while the other provides a current sink. This
permits the use of current sources in IC designs implemented with processes that do not allow p-n-p devices.
Analog building blocks such as voltage-to-current converters, active loads, and sink and source current mirrors
can be constructed from the new circuits using only n-p-n devices. Furthermore, because these circuits achieve
the required precision without the use of high-gain amplifiers, the bandwidths of the circuits are large compared to conventional configurations. The source currents are dependent on a single reference voltage and exhibit good temperature sensivitity

说明： ARM与51编写程序的区别
测试环境：KEIL ARM的空间统一编址，单片机的空间独立编址 ARM没有bool变量，单片机可采用bit变量(ARM write programs with 51 different test environment: KEIL ARM room for a unified addressing, single-chip ARM addressing space is not an independent bool variable, the variable bit microcontroller can be used)

Waveguidecharacteristicsofradiowavepropagation
说明： 对流层大气波导，可以使电波在较小的衰减下实现超视距传播，从而对无线电电子系统的运作产生严重的影响。对于通讯电路，它使系统间的相互干扰题目变得复杂；对于探测系统，产生的则是雷达空洞、超视距探测等题目。因此开展大气波导环境中电波传播特性及其应用的探究具有重大的理论意义和军事价值。
(Tropospheric waveguide, can make waves in the smaller attenuation achieve-the-horizon communication, and thus the operation of radio-electronic systems have a serious impact. For the communications circuits, which allows the mutual interference between systems has become a complex subject for the detection system is generated by the radar empty-the-horizon detection and other topics. Therefore, to carry out atmospheric environment of radio wave propagation characteristics of waveguides and its application to explore the theoretical significance and of great military value.)
