at specific angle造句

• The diffracted electrons interfere constructively at specific angles according to the crystal structure and spacing of the atoms at the sample surface and the wavelength of the incident electrons.
• The characteristic X-rays come out at specific angles, and since the angular position for every X-ray spectral line is known and recorded it is easy to find the sample's composition.
• The tracks are traced at specific angles to prevent " mis-tracking, " or the distortions that can result when a signal is picked up from an adjacent track during playback.
• Incident electrons diffract from atoms at the surface of the sample, and a small fraction of the diffracted electrons interfere constructively at specific angles and form regular patterns on the detector.
• In support of this theory is the experimental observation that the visual cortex neurons respond even more robustly to sine-wave gratings that are placed at specific angles in their receptive fields than they do to edges or bars.
• The then-conventional use of a single detector rotated about an illuminated sample with intensities collected at specific angles was called " differential light scattering " after the quantum mechanical term " differential cross section ", " ? ( ? ) " expressed in milli-barns / steradian.
