The ab initio evolutionary algorithm is used to search for all thermodynamically stable Na-Te compounds at extreme pressure.In our calculations, several new structures are discovered at high pressure, namely, Imma Na2Te, Pmmm NaTe, Imma Na8Te2 and P4/mmm NaTe3.Like the known structures of Na2Te (Fm-3m, Pnma and P63/mmc), the Pmmm NaTe, Imma Na8Te2
When conducting scientific research, the authors solve the problem of implementing a multi-purpose and accurate external target designation in real time, for the targets and critical facilities along the line of sight and beyond it.They achieve Drive Shaft minimal dependencies of the external target designation result on the complexity of the targe
