1. The flowers often form a conspicuous flat-topped umbel.

2. "You see that big, flat-topped hill over there?" he said, pointing west.

3. A flat-topped beam can be achieved by a suitable choice of the transform order for the Cosine-Gaussian beams with the modulation parameter.

4. The Focusing property of flat-topped multi-Gaussian laser beam by lens with spherical aberration is discussed. on the basis of generalized Huygens-Fresnel Diffraction integral formula.

5. Specially, the behavior of the spectral transition of flat-topped beams in turbulence is very different from that of Gauss-Schell-model (GSM) beams, and the difference is discussed.

6. The fractional Fourier transform of partially coherent flat-topped beams is also studied.

7. But the complex, differentiated teeth with the high-crowned, flat-topped and multifaceted molars that are unique to some mammals told a different story.

8. The flat-topped mountain, formed by six million years of erosion, is home to one of the world's most diverse floral kingdoms, with nearly 1, 500 species of flower.

9. The flat-topped type is used for the electron velocity distributions.

10. The influence of atmospheric turbulence on partially coherent flat-topped Gaussian beam is studied numerically in this paper.

11. A flat-topped or rounded flower cluster in which the individual flower stalks arise from about the same point, as in the geranium, milkweed, onion, and chive.

12. It is shown that a flat-topped intensity profile of the resulting beam can be obtained at a certain plane by an appropriate choice of the parameters of Hermite-Gaussian beams.

13. The flat-topped mountain, formed by erosion, is home to one of the world's most diverse floral kingdoms, with nearly 1,500 species of flower.

14. Teams of horses in single file hauled trains of a dozen flat-topped wagons loaded with granite along these rails.

15. The spherical aberration results in an increase of the beam quality factor of flat-topped beams.

16. The results show that we can conveniently control the intensity distribution of the partially coherent flat-topped beam by use of the fractional Fourier transform optical system.

17. A model of flattened Gaussian is used to simulate the flat-topped beam, and the beam order N is defined as the flattened degree.

19. The analytical expressions for the mode coefficients and M2-factor of partially coherent flat-topped beams which can be combined by independent Hermite-Gaussian beams have been derived.

20. A felt cap for a man; shaped like a flat-topped cone with a tassel that hangs from the crown.
