All studies show that weak plane inclination, thickness and whether be run through or not have a significant impact on longitudinal wave velocity, average modulus and strength of specimens.

研究结果表明：弱面的倾角、厚度及是否贯通等对试样的纵波速度、平均模量和强度具有显著的影响。

I would expect, whether you're a Red Sox fan or not, you to be able to look at a list of different pitchers and their average velocity for their fastball, and tell me who has the longest or the shortest wavelength.

无论你是否是一个红袜队球迷，我预想你会看到一系列,不同的投手和他们,投出快球的平均速度，告诉我谁有最长的,或者最短的波长。
