正如管道的长度和截面会影响水流一样,导体对电流的影响也是如此。
Just as the length and cro - section of the pipe affect the flow of water so it is with conductors of electric current.
试验结果表明,出水池长度较长,收缩角较小的高位井中的水流流态较好,但池内泥沙淤积程度较重。
Test results show that the flow regime is good in a head tank with a greater length of the outlet pond and a smaller contract angle, while the sediment deposition is heavy.
正如管道的长度和截面会影响水流一样,导体对电流的影响也是如此。with表示关系和范围,有“关于”,“对”,“就”之意。
Just as the length and cross-section of the pipe affect the flow of water so it is with conductors of electric current.
