急急急！把中文翻译成英文！（不是很难）

把下面这段话翻译成英文： 传统的电缆故障检测方法包括电桥法、时域反射法和频域反射法，这些方法只能离线检测电缆的故障，因此，无法检测持续时间很短的间歇性故障。序列时域反射法和扩频时域反射法利用随机序列的相关特性实现了电缆故障的在线检测，解决了这一问题。然而，二者的空间分辨率均受限于伪随机码的码率，要想进一步提高分辨率需要昂贵的高速伪随机码发生器，而且受伪随机码周期性的影响常常会引入虚警和误判。 |

| traditional ways to examine the problem of electric cable include bridge method,time domain reflection method and frequency domain reflection method,but those methods must be applied off-line,so they can't detect intermittent problems of short time.Sequantial time domain reflectometry and extended frequency domain reflection make on-line detecting possible.Still,the space resolution of this two methods are limited by code rate of the pseudo-random code,not only the expensive high speed pseudo-random code generator is required if you need to improve resolution,but also false-alarm and erroneous judgement are brought in with the periodicity of the pseudo-random code. |
