摘　　要：核磁共振NMR是一个基于原子核特性的物理现象,在稳定磁场作用下,原子核处于一定的能级,如果用适当频率的交变磁场,可使原子核在能级间产生共振跃迁,称为核磁共振。核磁共振技术是利用水中氢质子的磁共振现象,在不破坏物质结构的前提下,快速、准确获得物质内部结构信息的一种探测技术。近年来,该技术已经被广泛应用于物理、化学、医疗、石油、化工、考古、食品等众多科技领域。由此核磁共振的技术原理,昭示了其在水利行业的广泛应用前景。Nuclear magnetic resonance(NMR)is a physical phenomenon based on nuclear characteristics.The nucleus is in a certain energy level under the action of stable magnetic field.The nucleus can produce resonance transition between energy levels if alternating magnetic field with appropriate frequency is used.It is called nuclear magnetic resonance.NMR technology is a kind of detection technology that the magnetic resonance phenomenon of hydrogen protons in water is utilized to obtain the internal structure information of substances quickly and accurately without destroying the structure of substances.The technology has been widely used in physics,chemistry,medical treatment,petroleum,chemical industry,archaeology,food as well as many other scientific and technological fields in recent years.Therefore,the technical principle of NMR shows its wide application prospect in the water conservancy industry.
