GaAs films were grown with molecular beam epitaxy (MBE) method on Si substrates defected from plane (001) at 6° towards [110]. The processes of epitaxial layers nucleation and growth were controlled with the RHEED method. Investigations of the crystallographic properties of the grown structures were carried out by the methods of X-ray diffractometry and transmission electron microscopy (TEM). It is shown that the cyclic annealing and the LT-GaAs layers reduce the density of threading dislocations. The orientation GaAs film and the introduction of dislocation filters have little effect on the crystallographic properties of flms of GaAs/Si (001). It was found that in the LT-GaAs/Si layer the arsenic clusters are formed, as it occurs in the LT-GaAs/GaAs system without dislocation.
采用分子束外延（MBE）方法，在平面（001）向[110]方向倾斜 6° 的硅衬底上生长了砷化镓薄膜。外延层的成核和生长过程由 RHEED 方法控制。利用 X 射线衍射仪和透射电子显微镜（TEM）对生长结构的晶体学特性进行了研究。结果表明，循环退火和 LT-GaAs 层降低了穿线位错的密度。取向砷化镓薄膜和引入位错过滤器对砷化镓/硅（001）薄膜的晶体学特性影响很小。研究发现，在低温砷化镓/硅层中形成了砷簇，就像在没有位错的低温砷化镓/砷化镓系统中一样。

The article describes the model of the interaction of cavitation zone formed under the action of ultrasonic vibrations and interphase boundary of gas and liquid media, which spreads on solid surface in the form of liquid layer. It is shown that this interaction leads to the generation of capillary waves and consequently to the increase of efficiency of physical-chemical processes due to enlarged “liquid-gas” boundary. The analysis of the model allows determining square of interphase surface in dependence on amplitude, frequency of ultrasonic oscillations and liquid properties. It allows to determine the modes of ultrasonic action, which is necessary for maximum increase of contact surface area, in turn it leads to the growth of speed of the realization of physical-chemical processes based on surface interaction of dissimilar substances. As a result of the analysis it was determined that the most appropriate frequency of ultrasonic action is 60 kHz, at which increase of contact surface from 200 to 780 m2/m3 (at 5 mm thickness of liquid flm) can be achieved.

Two new simple printed structures providing low-cost and effective protection against ultrawide band pulses are proposed. The possibility of the 20 times attenuation for the structure of asymmetrical modal filter without resistors is shown. The possibility of the 2.5 times attenuation for another widely spread structure - a widely spread turn of a meander line - is demonstrated. Devices based on the proposed structures will be reliable, cheap and radiation-resistant due to the absence of any components.
