(1) Trunk and branches usually without adventitious sprouts; umbo flat or blunt.

(2) The handle of the malleus, with the umbo at its tip, crosses the drum obliquely from the cone of light upward toward the short process.

(3) Compared with the D-larvae and the umbo -larvae, the densities of the post larvae and the settled spats show rapid reductions at the end of the development process.

(4) Results: The results showed that the effusion of the middle ear decrease the amplitude of stapes footplate and umbo, weaken the incoming energy of the inner ear, thus leading to hearing loss.

(5) Sandaogou gold ore is the deposit of new type which is found in the middle of the umbo in Jiamusi these years, the district is volcanic in Mesozoic.

(6) My was held in July 1948, six months before our migration . Umbo was the only Chinese person invited and I still remember him explaining the significance of his gift to me.

(7) The relative concentrations of carotenoid in nacre are closely associated with the color of nacre and tend to reduce gradually from posterior to umbo region in nacre of the same shell.

(8) Result Amplitude variation laws of the stapes footplate and umbo were obtained by comparing the frequency response analytic results between the normal ear and pathological ear.
