因为微波波长比广播的波长要长，它会被各种物体吸收，特别是水——比如微波炉的使用原理。
Because they have a longer wave length than radio waves, microwaves can be absorbed by tissues, especially watery tissues, -hence their use in the kitchen.
大战以后，科学家又开创了微波波谱学，目的是探索光谱的微波范围并把其推广到更短的波长。
After the war, the scientists also created themicrowave spectroscopy, the purpose is to explore the microwave rangespectrum and its extension to shorter wavelengths.
