查询词典 crest

And by applying the linear dispersion relation of wave, all the properties of wave refraction including wave rays, constant phase lines, phase function and crest lines etc., can be expressed in explicit functions. By introducing an orthogonal curvilinear coordinate along the wave ray and the constant phase line, and with an estimated scale factor, the refraction coefficients along any wave ray can then be determined. The present results are verified by ordinary wave ray theory and some previous numerical results.

就此特例情况在波浪的线性分散关係的应用下，前进波浪折射现象的整体特性，包括波向线、等位相线、位相函数与波峰线皆被导述出明確显然的函数表示；同时引入由沿著波向线与等位相线所构成的完全符合波浪折射几何通性的正交曲线座標，求出其尺度因子后，由能通量守衡原则定出沿著任一条波向线上的折射係数；並由之对往昔纯依两相邻的波向线间的几何类比所给定的折射係数给予导証之。

For wedge grafts the cuts are made at a right angle to the crest. Jones[1] et al. have found that full-thickness iliac grafts harvested with a power saw are stronger than those harvested with an osteotome, presumably because of less microfracturing of bone with the saw.

与髂嵴成直角可切取楔形骨块，Jones[1]等发现以动力锯切取的全厚髂骨块的强度要高于骨刀切取的骨块，可能是因为应用骨刀切取对髂骨块可造成更多的显微骨折。
