摘 要：建立了几个军事短波通信系统仿真模型，并简要叙述了军事短波通信系统中跳频、扩频的干扰方程。文章给出了仿真物理结构图以及功能模块图，也给出了军事短波通信抗干扰性能仿真评估的指标，提出了利用云模型及云不确定性推理对仿真结果进行评估，并给出了干扰和无干扰条件下军事短波通信的抗干扰性能评估结果。-Abstract: A number of military HF communications system simulation model, and a brief description of the military short-wave frequency-hopping communication systems, spread spectrum interference equation. In this paper, simulation of the physical structure and function module map also gives the military a short-wave communications simulation to assess anti-interference performance indicators, the use of cloud model and the cloud of uncertainty reasoning to assess the simulation results are also given interference and non-interference under the conditions of military HF communication the results of the assessment of anti-interference performance.

为了便于我们分析和识别电路，更好的理解555电路，这里我们这里按555电路的结构特点进行分类和归纳，把555电路分为3大类、8种、共18个单元电路。-In order to facilitate our analysis and the identification circuit, a better understanding of circuit 555, here we are here by the structural characteristics of the circuit 555 classified and summarized in the circuit 555 is divided into 3 broad categories, eight kinds, a total of 18 unit circuit.

本作品采用Atmel公司的AT89C51单片机，以汇编语言为程序设计的基础，设计一个用四位数码管显示时、分的时钟。在实物图中，左边靠近电源的绿色发光二极管（长亮）是电源指示灯，表示的是5V稳定电源工作正常；单片机左下角红色发光二极管是秒灯，每闪烁一次表示时间走动一秒钟；按键正上方绿色发光二极管是设置灯，当时间正常走动时此时不亮，当第一次按下设置键（右键）时，此绿灯亮，同时秒时熄灭，且分钟的两位数码管出现闪烁，时间停止走动，进入校时状态，表示此时可以进行分钟的调整，当按一次加一键（左键）可实现分钟的加一功能，分钟以60分为极限，超出60分则返回数值0，从0再重新算起；如果再次按下设置键时，这时秒灯和设置灯仍旧保持熄灭和点亮状态，表示分钟的数码管停止闪烁，反过来表示小时的两位数码管则开始闪烁，此时可进行小时的调整，按加1键可实现小时的加1功能，小时调整以24为上限，同样超出24小时则从新回0；当第三次按下设置键时，数码管停止闪烁，设置灯熄灭，秒灯重新闪烁，时间以设定值计时。-err

给出了一种适用于PHS基带系统中的高性能成形滤波器,对比两种实现方法在基带芯片中 的性能,利用最少的非零比特位来表示符号数的编码技术即符号数(Canonic Sign Digit, CSD) 。-Applicable to this paper, a PHS base band system of high-performance shaping filter, compares the two methods in the base-band chip performance, the use of the least bit non-zero-bit symbols to express the number of coding technology that is the number of symbols ( Canonic Sign Digit, CSD).
