苏修已建成一条供实验用的远距离激光中继电话通讯线,从亚美尼亚首都埃里温到27公里以外的保鲁肯天体物理观测台,然后再到莫斯科。实验表明,它能以极高的精度传递大量的信息。一般情况下,雾和其他低层大气现象会影响光传输,但由于苏修南部 Su Xiu has built an experimental long-distance laser trunk telephone communication line, from the Armenian capital Yerevan to the Pauruk astrophysics observatory 27 km away, and then to Moscow. Experiments show that it can transmit a lot of information with high precision. Under normal circumstances, the fog and other low-level atmospheric phenomena will affect the light transmission, but due to Soviet revisionism southern
