We have studied the most promising material of semiconductor nanotechnology BaTiO3. Barium titanate, a compound of barium and titanate oxides, was studied in three dimensional varieties: in the form of powder with a diameter of 1÷1.5 mm, solid BaTiO3 target with a diameter of 76 mm and thin films obtained by ion-plasma sputtering with a thickness d ≈ 10÷50 nm, on the Si (III) surface. The spectra were recorded at room temperature on an XRD-6100 powder X-ray diffractometer, and spectra were taken from room temperature to 673 K, and the amorphous and crystalline phases of this substance were determined based on the obtained X-ray diffraction spectrograms. The peaks of the spectrogram based on the Miller indices and interplanar distances dhkl show complex compounds that are newly formed on the basis of barium titanate.
The article describes the dynamics of drill bits, drilling modes, distribution of resistance forces when drilling with bits. The theory of drilling a well of arbitrary shape, possible shapes of contacting figures at the bottom hole and the type of drill bit operating in the rotation pair mode are considered. This type of bit has the properties of a double center of rotation, which results in attrition drilling. At the same time, during drilling, the load on the bit will be located the same throughout the working part, it is also theoretically shown that the specific volumetric and contact work of the cutting parts will be the same, which leads to the same wear of the bit. It also discusses the issues of improving the flushing and blowing of wells when drilling with rotary steam bits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
