what are the first two frequencies at which destructive interference occurs?
前两个是什么在这毁坏性的干扰频率发作?
we have destructive interference here.
这里是相消干涉。
it is found that the complete destructive interference in the four-pinhole interferometer may appear, and there may exist phase singularities of intensity and spectral degree of coherence.
结果表明,一定条件下,可出现完全相消干涉,并存在光强和光谱相干度的相位奇点。
in this way the summer palaces - new and old - are also associated in popular culture with the destructive interference of foreigners.
至此新老结合的颐和园也关系到通俗的文化就是外国人的破坏性干扰。
just like we see destructive interference with water waves or with light waves, we can also see destructive interference with orbitals.
就像我们看到水波,和光波的相消干涉,我们也可以看到轨道的相消干涉。
but besides the many potential advantages of ultra-high field mri, there are also some methodological challenges like the destructive interference of transmit rf fields within typical volume coil.
