Installing more AC lines or more powerful superconducting lines alone would increase transmission capacity but could lead to bigger ripples in the grid if something went wrong. 接更多條的交流電線(xiàn)或超導線(xiàn)可以增加傳輸容量，但出問(wèn)題時(shí)也會(huì )在電力輸送網(wǎng)內引成更大的漣漪。
Technology progress is distinguished by immensely increased speed, capacity and functionality for information storing and processing and by the ability to transmit at lower cost. 技術(shù)進(jìn)步的特點(diǎn)是大幅度提升了的信息儲存與處理的速度容量和功能，以及成本更為低廉的傳播能力。
