Excitation and Detection of Nonlinear Waves on a Charged Surface of Liquid Hydrogen

A new technique for exciting nonlinear waves on a charged surface of liquid hydrogen is described. Methods of optical detection of surface oscillations in experiments on capillary turbulence at frequencies of up to 10 kHz are discussed. The results of a study of capillary waves on the surface of liquid hydrogen are presented.     

多进制数字调相系统分析与设计方法的探讨

对数字通信中MPSK系统的调制与解调问题进行了较为的分析，并以8PSK和循环码16PSK系统为例，阐述其调制器电路的逻辑设计方法。在此基础上给出了8PSK系统调制与解调的一种方案，讨论了循环码和自然二进制码16PSK系统的调制器的具体设计过程，该设计方法可应用于一般MPSK系统的逻辑设计。     

Features in the electromagnetic field intensity distributions near the source in a stochastic discrete medium

Spatial distributions of the average and coherent intensities of the electromagnetic field in a stochastic, strongly fluctuating discrete nonlossy medium are studied by experimental and theoretical methods. It is established that, at a certain density of the medium, the average field intensity near the source immersed into this medium can significantly exceed the value in the free space.
