The medium used to transmit information limits the speed of the network, the effective distance between computers, and the network topology. 传输信息的媒介质限制了网络传输的速度和制约着两台计算机之间的距离,并影响着网络的拓扑结构。
The effective distance of TV system in electro-optic tracker is one of the key performances, which must be calculated, analyzed and studied when the system is designed. 光电经纬仪是靶场重要的测轨设备,经纬仪的电视系统作用距离是其关键指标之一,在系统设计过程中,必须给予充分论证。
Similarly for a weapon of lower energy, the effective distance is less, but so also is the rate of ascent of the cloud. 同样,对于威力较低的武器来说,有效距离(ED)要小些,云的上升速度也同样小些。
The ionization has an effective distance of1m. 离子作用距离可达一米。
Increase the effective distance between fracture length and acid by acid-fracturing treatment is a key to improve acid-fracturing producing rate for carbonate reservoir. 碳酸盐岩储层通过酸压改造,提高裂缝长度和酸液有效作用距离,是提高酸压措施建产率的关键。
