first arrival的用法和樣例：
例句
- The tomographic inversion of the surface layer velocity model with the first break is the important base of the tomographic static correction.
初至波表層速度模型層析反演是層析靜校正的重要基礎。 - This problem was effectively solved by using nonlinear first break tomography inversion static method to take the place of the small refraction and uphole.
為此，用非線(xiàn)性初至波層析反演靜校正方法替代小折射和微測井技術(shù)，有效地解決了長(cháng)波長(cháng)靜校正問(wèn)題。
