theoretically the aliasing of sparse arrays could be discriminated by two signals with different frequencies, but it could not be eliminated completely in the presence of noise.
理论上根据两个不同频率信号可以解稀疏阵列相位模糊,但由于噪声干扰并不能完全消除稀疏阵列相位模糊。
the pollution of sulfur dioxide is eliminated completely and the sulfur resource is utilized effectively by the way of producing sulfur, liquid sulfur dioxide, sodium sulfite and sodium pyrosulfate.
