JS 拷贝：浅拷贝 / 深拷贝原理 + 常用方法

In this letter, we show a nilpotent matrix representation of the exterior derivative operator in noncommutative geometry (NCG), by translating the noncommutative relations of the algebraic formalization into the original one. As a result, we can construct the extended gauge theory without complicated algebraic rules nor excessively large differential algebra and non-monomorphic representation.

在清管、检测作业中如何对清管器和内检测器进行监测跟踪与定位是长期困扰管道运营的一个技术难题。而光纤传感技术，可以实现对清管器和内检测器的监测跟踪和准确定位。论文详细介绍了光纤传感技术的原理，并通过具体的案例详细介绍了其在油气管线内检测作业中的应用。
