The influence of a glow electrical discharge on the wake behind two cylinders was studied. This effect consists in a redistribution of the power in the velocity pulsation spectrum due to the discharge action on fluid flow. To treat this observation, we need a simple model of intermittent turbulent wake in the vicinity of cylinders. A variant of such model has been developed in the form of two coupled van-der-Pole oscillators representing two interacting von Karman vortex streets behind the cylinders. According to the model, the set of the global wake modes and its concurrence are discussed. Accordingly, a mechanism of the glow discharge effect on the cylinders wake has been proposed.

非晶合金具有独特物理和力学性能,如何建立非晶合金微观结构非均匀性与物理/力学性能之间的关联是非晶固体的重要研究课题之一.微合金化是调控非晶合金微观结构有效手段之一.本研究以玻璃形成能力优异的Zr_(50-x)Cu_(34)Ag_(8)Al_(8)Pd_(x)(x=0,2)非晶合金为模型合金,借助差示扫描量热仪和电磁声转换设备,研究非晶合金铸态、弛豫态和结晶态热流和剪切模量随温度的演化规律,以及物理时效(低于玻璃转变温度)过程剪切模量的变化随时间演化规律.基于自间隙原子理论,利用热流曲线表征非晶合金在相同热历史剪切模量热效应.通过分析铸态和弛豫态自间隙缺陷浓度和激活能谱,发现结构弛豫导致自间隙缺陷浓度减小,诱导剪切模量随温度演化偏离软化过程,并伴随体系放热.与此同时,研究发现添加微量Pd元素可抑制模型合金体系原子迁移,增加特征弛豫时间.本研究从非晶合金模量热效应角度进一步理解非晶合金微观结构非均匀性.

The mechanisms of the laser-stimulated diffusion of indium in CdTe have been studied. The structures of a thin In film on the CdTe substrate were irradiated by nanosecond pulses of ruby, KrF excimer and Nd: YAG lasers. It is established that the dominanting mechanism of In diffusion in CdTe at solid-phase (before CdTe melting) doping is baro-diffusion. The diffusion coefficient and average drift velocity of indium are determined. The temperature dynamics and kinetics of laser-induced phase transitions are studied by numerical simulation on the basis of Stefan problem.

The paper reports some technical solutions, which suggested or used for increasing of environmental protection during accidents at NPPs. For NNPs with two protective shells and pressure release system such as WWER-1000 a comprehensive, passive-mode environmental protection system of decontamination of the radioactive steam-air mixture from the containment and the intercontainment area was suggested. This system includes the “wet” stage (scrubbers, etc.), the “dry” stage (sorption module), and also an ejector, which in a passive mode is capable of solving the multi-purpose task of decontamination of the air-steam mixture. For WWER-440/230 NPPs three protection levels: 1) a jet-vortex condenser;2) the spray system;3) a sorption module were suggested and installed. For modern designs of new generation NPPs, which do not provide for pressure release systems, a new passive filtering system together with the passive heat-removal system, which can be used during severe accidents in case all power supply units become unavailable, was proposed and after modernization was installed at the KudanKulam NPP (India).
